Set -Up Manual Page 2
3.1 Location and Layout Use Of Zone Maps. Your
home is designed for certain weather conditions and
roof loads (see zone maps in a bedroom closet or
near main electrical panel and Figure 31 of this
manual). Do not site or relocate your home in a zone
requiring greater wind, roof load, or heating /cooling
capabilities than those for which it was designed.
However it is safe to locate your home in an area
with lower load or weather requirements. For
example, a home designed for a northern roof load or
40 psf may be sited in the southern roof load zones.

3.2. Soil Conditions
3.2.1 Requirements. To help prevent settling of your
home, site it on firm, undisturbed soil or fill
compacted at least 90% of its maximum relative
density Installation on loose, uncompacted fill
may cause the home to shift and settle in such a
way as to damage the home which may invalidate
the home's limited warranty
3.2.2. Bearing Capacity Test the bearing capacity of
the soil at the depth of the footings after completing
any grading and filling (see 3.2.3) If you can't test
the soil but can identify its type, use the foundation
bearing pressure shown in Figure 3.2 as a guide.
If you cannot identify the soil, use the lowest value
(1 000 psf from Figure 3.2). Under unusual
conditions, or if the soil appears to be peat or
uncompacted fill, consult a local geologist or
professional engineer
3.2.3. Soil Bearing Testing Methods and Equipment.
A pocket penetrometer (available from engineering
supply houses) or other methods acceptable to
local jurisdictions may be used.
3.3. Removal of Organic Material. Remove all
decayable material such as grass, roots, and wood
scraps from beneath the home, especially in areas
where footings are to be placed, to minimize
settling of footings and insect damage. Remove
shrubs and overhanging branches from the
immediate vicinity of the homesite to prevent
windstorm damage.
3 4 Drainage.
3 4 1 Purpose. Drainage prevents water buildup under
the home which may cause settling of the
foundation, dampness in the home, damage to
siding and bottom board, buckling of walls and
floors, problems with the operation of doors and
windows, AND COULD VOID YOUR WARRANTY
3.4.2. Elimination of Depressions. Grade the homesite
to permit water to drain from under the home and
away from home for a minimum of 10 feet from the
side of the home. See Figure 3 3

3 4 3. Drainage Structures. Depending on the local
landscape, ditches and culverts may be needed to
drain surface runoff If so, consult a registered
professional engineer
3.5 Ground Moisture Control.
3.51 Importance. If the crawlspace under the home is
to be enclosed with skirting or other material, a
vapor retarder ground cover shall be installed that
keeps ground moisture out of the home. Where a
concrete pad is installed (solid) under the entire
home floor area, the vapor barrier is not required, if
the concrete is a minimum of 4' thick.
3 5.2. Acceptable Types of Ground Cover Use
polyethylene sheeting or its equivalent, at least six
mils thick.
3.5.3. Proper Installation. Cover the entire area under
the home with the sheeting and overlap it at least
6' at all joints. Where soil and frost condition
permit placement of footings at grade level, place
the sheeting directly beneath them.

4 Chapter 4- Foundations
NOTE. This chapter covers only foundations.
Figure 4 1 and Table 41 summarizes the usual
types. Set -up procedures and methods for
securing the home to its foundation are discussed
in Chapter 5
4 1 Piers.
41 1 Importance. Incorrect size, location or spacing of
piers may cause serious structural damage to your
home. It is important to install piers around the
perimeter if required for your home. Failure to do
so may lead to sagging floors, walls and roofs, and
could void your limited warranty
41.2. Acceptable Types. Piers are to be concrete
blocks capped and shimmed with wedges, or
adjustable manufactured metal or concrete stands
(See Figure 4 1).
4 1 3. Design Requirements.
41 3 1 Load Bearing Capacity The load that each pier
must carry depends on factors such as the
dimensions of the home, the roof live load the
spacing of the piers, and the way they are used to
support the home. Center beam/marriage wall
blocking is required for multi- section homes.
See tables 4.2 and 4 3 for pier loads. Piers must
be rated to resist the noted loads (see 4 1 3.2)
4 1 3.2. Configuration. Figure 4 1 shows the
recommended arrangement of concrete block piers
constructed on -site. Concrete blocks are to have
nominal dimensions of at least 8' x 16' They must
be stacked with their hollow cells aligned vertically
When piers are constructed of blocks stacked side
by -side, every layer must be at right angles to the
previous one (see Figure 4 1).
Cap hollow block piers as shown in Figure 4 1 to
distribute the structural load evenly across them.
Caps shall be of solid masonry or hardwood, and
of the same length and width as the piers they rest
upon. Avoid plywood, as it may lead to unwanted
settling or movement.
Use 4 x 6' hardwood shims to level the home and
fill any gaps between the base of the I -beam and
the top of the pier cap Always use shims in pairs
(see Figure 4 1) Drive them in tightly so they do
not occupy more than 1 of vertical space. When
the space to be shimmed is less than the minimum
thickness of available caps or concrete blocks,
pressure treated hardwood dimension lumber may
be used under the caps.
Set -Up Manual Page 5
Select manufactured pier heights so that their
adjustable risers do not extend more than 3' when
finally positioned.
All piers must be set on footings (see Paragraph 4.2)
that are installed in such a manner so as to provide a
stable environment for your home
41 3.3 Clearance Under The Home. After the
home is leveled, the resulting distance
between the bottom of the chassis and the
ground must be no less than 12' for 75% of
the home. The remainder of the home may
be less than 12' above the ground but may
not touch the ground. The maximum
clearance should be no more than the
maximum described in Figure 4 1
4 1 4 Design Procedures.
4 1 4 1 Piers Up To 36' High. You may construct
piers less than 36' high out of single, open or
closed -cell concrete blocks, 8' x 8' x 16'
Install them so that the long side is at right
angles to the supported I -beam (see Figure
4 1) Position open cells at right angles to the
footers. Horizontal offsets should not exceed
1/2' top to bottom. Mortar is not normally
required. Manufactured piers should be listed
and labeled. Do not extend their adjusting
studs beyond the limits specified by the
manufacturer of the pier
4 1 4.2. Piers 36' To 80' High. Construct all piers
between 36' and 80' high, and all corner piers
over three blocks high, out of double,
interlocked concrete blocks (see Figure 4 1).
Mortar will not normally be required.
4 1 4 3 Piers Over 80' High. Where permitted by
local codes, lay them in concrete mortar with
steel reinforcing bars inserted in the block
cells and fill the cells with concrete Where
such construction is not permitted by local
codes, have piers over 80' high designed by
a registered professional or structural
engineer
41 5 Location And Spacing. The location and
spacing of piers depends upon the
dimensions and weight of the home, the roof
load zone, the type of construction and other
factors such as the locations of doors or other
openings and heavy pieces of furniture In
general, locate piers no more than 2' from
either end (unless specified) Place piers of
your home as follows:
4.1.5.1 Single And Multi- Section Homes.
A) Homes not requiring perimeter support.
Figure 4.2 shows the recommended location
and spacing of piers for homes not requiring
perimeter blocking generally located at south
(20 PSF) and middle (30 PSF) roof zone areas.
B) Homes requiring perimeter support. See
Figure 4 3 for homes requiring additional
perimeter supports (generally at 40 PSF or
higher roof load zones)
4 1 5.2. Under Doors And Heavy Furniture. Place
piers on both sides of all exterior doors,
sidewall openings wider than 4 (such as entry
and sliding glass doors), under porch posts,
fireplaces and wood stoves, and under the
expected locations of heavy pieces of furniture
such as pianos, waterbeds, etc. This
additional blocking is required with all types of
foundation.
4.2. Footings. Support every pier with a properly
designed footing as follows.
4.2.1 Acceptable Types Of Footings.
4.2.5 1 Concrete. Footings may consist of precast of
poured -in -place concrete, pads slabs, or
ribbons with a 28 -day compressive strength of
at least 3 000 psi (see Figure 4 4 for minimum
footer thickness).
4.2.5.2. Other Materials. You may also use other
materials approved for this use by local
authorities if they provide equal load- bearing
capacity and resistance to decay
4.2.2. Footer Placement. For homes which are to
be set in areas susceptible to frost, in order to
prevent the potentially harmful effects of frost
heave, footings should be placed below the
frost line or the home must be installed in such
a manner as to provide a stable environment.
4.2.3. Proper Sizing Of Footings. Proper sizing of
footings depends upon the load- carrying
capacity of both the piers and the soil. See
Table 4 4 for recommended footing sizes
based on pier load (Table 4.2 and 4 3) and
minimum soil bearing capacity
4.2.4 Other Footing Design Considerations. You
should check with applicable state or local
building authorities concerning any other
requirements they may have concerning
design, construction or placement of
acceptable footings.
4 3. Permanent Foundations. Check local
building codes and regulations and consult a
registered professional or structural engineer
when you are setting your home on a
permanent foundation (such as a full
basement, crawl space or load- bearing
perimeter foundation) You may get a
Set Up Manual Page 6
permanent foundation design that meets most
local codes by writing to the address located
on the back cover of manual, Attention
Customer Service.
4 3 1 Flood -Prone Areas. We do not recommend
setting your home in river or coastal flood
prone areas. Special local regulations or flood
insurance provisions may apply Special
elevation and anchoring techniques are
required when locating in a flood -prone area.
Consult a registered professional or structural
engineer to make sure that the home design
and construction conform to applicable federal,
state and local codes and regulations. The
FEMA publication listed in Section 4 4 3
contains design and construction
recommendations.
4 3.2. Severe Wind Areas. Special foundation and
anchoring techniques are required when your
home is located in a severe wind area.
Consult a registered professional or structural
engineer HUD foundations design guide listed
in Section 4 4 4 contains recommendations for
designing foundations and anchoring systems.
Do not place your home in a wind zone more
severe than the one indicated on your home's
Data Plate.
4 3 3 Special Snow Load Conditions. Homes
designed for and located in heavy snowfall
areas or subject to other extreme loading
conditions will require special piers or footings.
See Table 4.2 for pier loads up to 50 psf roof
load For higher roof load consult a registered
professional engineer for your foundation
design. Do not place your home in a roof zone
more severe than the one indicated on your
home data plate

steel pedestals on permanent wood crushed stone or concrete footers. Ground anchors in soil angled to resist
straps or embedded in concrete deadmen soil. Straps tied to the frame with or without over the -top straps
2. Concrete slab or continuous footing. Home rests on a concrete slab or ribbons of concrete. Straps tied
between frame and perimeter footers or concrete slab Recommend installing earth anchors prior to pouring
concrete slab Concrete slab should be sloped to prevent water accumulation under home
3 Pile /post system. Home rests on piles /posts. Place sufficiently deep in the ground to resist all wind snow frost
heave and earthquake forces. Straps fasten home to piles /posts or caps placed thereon
4 Concrete or concrete block load- bearing perimeter walls (basement or crawl space). Home rests on exterior
load bearing walls which sit on concrete footings, sufficiently heavy to hold down home to resist all external forces.
REQUIRED FOOTINGS PIER BLOCKING
(For Homes NOT Requiring Perimeter Blocking)
In Table 4.2 below are the design loads used to determine the support structure for homes not requiring perimeter blocking.
The minimum values to be used for pier and footing design based on the indicated roof live load and a floor live load of 40
pounds per square foot (PSF) are specified in Table 4.2. See Figure 4.2 for typical pier layout. All required support locations
for marriage wall columns, side wall openings and any other special supports are marked by paint, label, decal or stencil.
Provide support (piers footings) at all marked locations per tables 4 4 4.5 as required. Note. Do not remove this support
location marking as these locations must be visible after home is installed.
All load bearing pier supports and footings may be subject to approval by the local enforcement agency As specified in
Table 4.2, each pier shall have adequate capacity to support the design load shown. The required sizes of footings will
depend on soil bearing capacity test results. In lieu of soil tests, confer with the local building authority for recommended soil
bearing capacity in your area. The areas beneath the footing shall have all grass and organic materials removed before
installation. All footers must be placed on either undisturbed soil or compacted fill. +��-�yy

NOTES.
1 See Table 4 4 for minimum footing sizes based on pier loads and allowable soil bearing capacities. The footing sizes and
pier loads are minimums required for the applicable conditions. The footing shall not be smaller than the pier it supports or
256 square inches.
2. The maximum spacing of supports is not to exceed 12 feet.
3 Where it is impractical to maintain spacing such as in the axles area, the average of the distance to each adjacent support
may be used to determine support requirements, for example if the distances to the adjacent supports were 6' -0' and 8' -0'
the average spacing would be 7' -0'
4 Homes located in the north (40 PSF) roof load zones MUST have perimeter blocking per Table 4.3 unless indicated
otherwise by a letter from plant of manufacturing

15 Chapter 5 Set -Up Procedures
5.1 Moving Home To Location. Make sure the
following items are completed before placing the
home:
1 The site is properly prepared. See Chapter 3.
2. All concrete work necessary to setting the home is
finished.
3 Utilities are installed or available.
4 Any trenching, for crossover drain lines or for wheels
that will be left in place is complete.
5 Items that could be difficult to install after the home is
sited (such as anchors and ground moisture retarders)
are in their proper locations.
CAUTION: THE HOME WEIGHS SEVERAL TONS. USE
ADEQUATE TEMPORARY SUPPORT BLOCKING TO
SAFEGUARD WORKERS. WOOD BLOCKING FOR YOUR
HOME IS RECOMMENDED.
51 1 Positioning the home. When not placing the home
on a concrete slab or poured -in -place footings, mark
the corners of the home and lay out footings, and
support devices close to where they will be used.
5 1.2. Then move the home or first section into position.
5.2. Singlewide Homes Blocking and
Leveling
5.2.1 Before doing any jacking place support piers for the
home in the locations under the home as specified in
the home installation instructions.
5.2.2. Use a minimum of two jacks, each with a. rating of at
least ten tons.
5.2.3. Jack only on the main chassis I -Beam. Locate the
jack directly under the vertical web of the I -Beam. Do
not jack on the seam (joint between flanges) of a twin
I -Beam.
5.2.4 Use a large 3/8 inch thick steel plate, C- channel or
other equivalent plate between the main chassis
Beam and the jack head to distribute the load.
5.2.5 The jack base, and any blocking, must be located on
firm ground
5.2.6. Do not operate the jacks while you are under the
main I -Beams of the home.
5.2.7 Use jacks only for raising the home. Do not rely on
the jacks to support the home
5.2.8 Place 4' x 6' x 48' minimum safety timbers between
the I -Beams and ground in case of jack failure.
Timber should be hardwood.
5.2.9 Raise the home in small increments and provide
additional blocking between the home and the piers
and safety piers as the home is raised.
5.2.10 Do not go under the home while it is supported on the
jacks.
FAILURE TO FOLLOW THESE WARNINGS MAY
RESULT IN SERIOUS INJURY OR DEATH.
Set -Up Manual Page 13
Reminders before jacking.
1 Use only jacks in good condition with a
minimum rating of 10 tons.
2. Use a Minute Man C- Channel jacking plate or
equivalent between jack and steel I -Beam to distribute the
concentrated loads from jack to I -Beam.
3 Use a firm support under the jack base to prevent
tipping or settling of the jack. A 12' x 12' or larger pad is
recommended.
4 Always follow the sequence of jacking outlined below to
avoid overstressing structural members.
5.2.11 The jacking procedure is as follows:
5.2.11 1.After the home is located in its final position,
you can preliminary level it by using the hitch
jack but only after adequately wheel blocking
the home so it does not roll.
5.2.11.2.Jack up one side of the home by placing one
jack just forward of the front spring hanger
and the other just behind the rear spring
hanger of the same I -Beam. These two
jacks must be operated simultaneously to
raise the home. Jack low side of the home
first. Install footings and piers; one just
forward of the front jack and another just
behind the rear jack (taking care not to
exceed the correct spacing selected from
Table 4.2.)
5.2.11 3 Next, jack the main I -beam at the front and
position a pier within 2' -0' of the end of the
I -Beam. At the completion of this step, this
side of the home should be approximately
level.
5.2.11 4 Repeat Steps 5.2.11.2 and 5.2.11 3 for the
other side of the home. At the completion of
this step, the home should be roughly level
from front to rear and from side to side.
5.2.11 5 Place the remaining pier supports under the
main I -Beam on each side taking care to
maintain a maximum distance of no more
than the spacing determined from Table 4.2
with piers located as specified at each end of
each I -Beam (see Figure 4.2)
5.2.11 6 Level the home within reasonable
tolerances, using a 6 foot carpenter's level,
water level or similar equipment. The final
height adjustment is obtained by jacking the
I -Beam and placing hardwood shims
between the piers and I -Beam or other
approved methods such as adjustable piers.
THIS LEVELING PROCESS IS
IMPORTANT FOR THE APPEARANCE
AND IS ESSENTIAL FOR THE PROPER
OPERATION OF DOORS WINDOWS AND THE
DRAINAGE SYSTEM.
5.2.11 7 Place additional supports at each side of
sidewall openings over 4' -0' wide and each
side of exterior doors.
5.2.11 8 Within 90 days after initial set -up the home
should be releveled; if necessary to
compensate for any pier settlement. Following
the procedure in Item 5.2.11 6 above.
5.2.11 9 NOTE. DURING THE LEVELING OR
RELEVELING PROCESS, LOOSEN FRAME
TIES AND OVER THE -ROOF TIES (IF
PROVIDED) PRIOR TO JACKING THE
HOME.
5 3 Multi- Section Homes
Blocking and Leveling
With the exception of the requirement for support
under the marriage walls of multisection units,
leveling and blocking procedure are the same as for
single section units. Prepare the site as previously
described. It may be desirable to construct the
footing and piers (to grade height) prior to moving the
home to its final location. Figure 4.2 and 4 3 illustrate
the typical pier layouts, making special note of
additional piers required at center beam support
locations. The following procedure describes the
setting of a double- section home only The
procedure required for a triple- section home is
similar except for the blocking leveling the 'T
Section first, prior to that of the 'U' Section and 'X'
section.
5 3 1 Leveling and blocking the U Half Figure 5 1
shows the way we recommend you level the home
To prevent tipping or settling, use a firm support
under jacks. Use a steel channel or plate between
jacks and steel beams to distribute the load Use
equipment in good working condition and strong
enough to handle the loads. Work safely whenever
you are under in or around a home that is being set.
Use the following jacking sequence.
5 3 1 1 Using the water level described in Figure 5 1
or a 6' level, check the level of the floor crosswise
in the axle area. If the floor is not level from side
to side, place the 10 ton jack under the low side I-
beam at the axle area and carefully raise the I-
beam until the floor is level. Place blocks under
the I -beam, on each side, at the pier points closest
to the jack. Insert wedges, as shown on Figure
5 1 so that the blocks bear the weight.
5 3.1.2. Place the level lengthwise on the floor and
working towards each end of the home, place
blocks and wedges under both I- beams, at
selected pier spacings. Make continuous checks
with the level, both lengthwise and crosswise. If
you must jack the U -side to keep it level as you
Set -Up Manual
work towards the ends, jack it only under the
beams and only enough to make it level.
5 3.2. Leveling and Blocking the X Half
CAUTION Do not proceed with the X -half
until the U -half is completely level and properly
blocked. After it is, proceed as follows:
5 3.2.1 Remove the plastic used to close up the open
side of each half during transportation, but DO
NOT remove the wood supports holding up the
ceiling at the open sides. Park the X -side as
closely as possible to the U -side. At this point,
insert a mating gasket between the two halves
at the floor line, endwalls and roof We
suggest use of 6' fiberglass insulation or an
equivalent sill sealer Slide the X -half
sideways to the U -half by using two come -a-
longs, placing one end on the U -half I -beam
and the other end on the X -half I -beam. Use
one come -a -long at the front and one at the
rear or more if necessary at interim locations.
5 3.2.2. Place a 10 ton jack under the X -half inside
beam about 1/3 of the floor length from each
end. Carefully jack the X -half inside I -beam
until the X -half floor edge is about even with
the U -half floor edge, as shown in Figure 5 3
5 3.2.3. Loosely lag the X -half floor joists to the U -half
floor per Figure 5 10 at Wind Zone 1 and per
Figure 513 for Wind Zone 2 and 3 To
prevent the splitting of rim joist pre drilling of
holes may be required. Do not tighten these
lags at this time.
5 3.2.4 Temporarily block the X -half inside I -beam at
selected pier spacings, removing the jacks and
place them under the X -half outside I -beam
about 1/3 of the floor length from each end.
5 3.2.5 Carefully jack the X -half outside I -beam until
the X -half floor is approximately level
crosswise. Temporarily block the X -half
outside I -beam at pier points. The X -half
should be very close to the U -half and the
small space (if any) between the floors and
ceilings of the X and U halves should be the
same. The two sides should now be loosely
attached at the floor joists. The U -side is
completely level and blocked. The X -side
should be nearly level because the ceilings
and floors were made to match up You are
now ready to level the X -half so that it is even
with the U -half and to permanently block it.
5 3.2.6 Place a 10 ton jack under each I -beam of the
X -half at the axle area. Carefully adjust the
floor to the X -half until it is level with the floor of
the U -half Go to the outside I -beam of the X
half and adjust it so that the X -half floor is level
crosswise. The X -half floor should now be
level crosswise and even with the U -half floor
Page 14
5 3.2.7 Place blocks under the I -beams on each side
of the X -half at the pier points closest to the
jacks. Insert wedges, as shown on the
drawing, so that the blocks bear the weight.
5 3.2.8 Work towards either end, placing blocks and
wedges under the I -beams on both sides, at
selected pier spacing. Make continuous
checks with the level to be sure that the floor of
the X -half is level and even with the U -half
CAUTION Do not over jack the X -half or you
will strain the lags attaching the two halves
together make the floor unlevel or cause other
problems.
5 3.2.9 Both halves should now be blocked and level.
Before tightening the lags through the floor
joists underneath the home, check all
alignments. Are the front and rear end walls
flush? Are the floors and ceilings flush? Space
floor lags per Fig. 5 10 at Wind Zone 1 and Fig
5 13 at Wind Zones 2 3
NOTE. When the two sections are in place,
aligned and leveled gaps between floors or
ridge beams, 1 1/2' wide maximum, which DO
NOT extend the full length of the home may be
closed up with plywood or lumber shims. The
lag screws in the shimmed portion may need to
be increased in length to ensure that they
engage both the floor rim or roof ridge beam
with the same penetration as area's without
gap Reduce the lag application angle to 30
degrees in gap area for proper penetration (see
Detail A fig 5 4)
5 3.2.10 Now that each half is properly
leveled and blocked, and the floors are securely
lagged together you are ready to move to the
ridge beam.
5 3 3 Roof Ridge Fastening. See Figure 5.4
5 3 4 End Wall Fastening.
5 3 4 1 Secure the end wall studs, where the
two halves come together, by driving #8 x 4"
wood screws every 8' into both sides of the
matching end wall studs at Wind Zone 1 (Ref
Figure 513 at Wind Zone2&3)
The home should now be level, properly blocked
and properly and securely fastened together
CAUTION Once again use the level and be
sure that the floor is properly level throughout
the home Many problems will result if the floors
are not level or if the home is not properly
fastened togetTher This is your final check for
level. Adjust the wedges between the blocks
and the I -beams so that the floor is level.

Apply a 2" wide strip of duct tape at the marriage joint of the
endwalls for the entire height of the walls. Apply the duct
tape directly over the sheathing.
The siding panels should be attached using 7/16 x 1 1/2" x
16 gauge galvanized steel or aluminum staples. (6d
galvanized nails may also be used.) Staples should be
driven so that there is a 1/32' clearance between the siding
and staple crown to allow some lateral movement. Fasten
every 16" to each stud. See Detail A for proper fastening.
Snap the bottom course of siding into the starter strip and
fasten to the wall. Leave a 1/4 space at corner posts and J'
channels around window and door openings to allow for
expansion. Do not fasten within 4 of an accessory Vertical
butt joints in panels should overlap 1 Do not fasten the
panel within 4 of the joint. Install vinyl aluminum, felt or
other suitable material for flashing at bottom corners of doors
and windows per Detail E. Apply caulk around siding and
light blocks, water faucets, or other small penetrations.
Install successive courses similarly to the first. Butt joints in
adjacent courses should be offset by at least 24 Joints in
alternate courses should be aligned vertically (see Detail B)
Panels will have to be cut at headers and sills. A single
panel should extend without joints across the width of the
opening When cutting a panel at a sill, measure the
distance between the bottom of the opening and the top lock
of the lower course, then deduct 1/4 (see Detail C
Slide the cut panel into the under sill trim and install. Note
that the undersill trim piece may have to be furred to
maintain the proper pitch of the siding
Measure and cut the header panel in the same manner as
indicated above.
The top sections at the gable will need to be angle cut. Use
two scrap pieces of siding to make a pattern (see Detail D)
Interlock one piece with the siding panel below Hold the
other piece on top against the gable. Mark a line on the
bottom piece and cut. Use this piece as a pattern for cutting
gable pieces. Install the gable pieces by interlocking with
the lower course, sliding into the gable J' rail and fastening.

5.5. Tie Down Requirements For Single And Multi
Section Homes.
5 5 1 Anchoring Instructions. After blocking and
leveling, the installer should secure the home
against the wind loads. The type of installation
determines how this should be done, as follows:
CAUTION* In order to avoid electrocution and
the possibility of damage to underground
services, prior to digging for the purpose of
securing anchors, make sure that the location
of underground electrical cables, gas lines,
sewer lines, and water lines are clearly marked
above ground.
5 5 1 1 Number And Location Of Anchors. Select the
number and location of straps and anchors from the charts
and diagrams from Figures 5 9 thru 5 13 Only listed and
approved ground anchors capable of resisting at least the
minimum loads given in the chart must be used.
5 5 1.2. Installation Of Anchors. Tie down systems are
designed using anchors with minimum working capacity of
3150 lbs. Installation of anchors (angle, stabilizer plates,
type of soiling, should be per anchor's installation
instructions.
When connecting more than one strap to a single anchor
lining the shaft of each anchor between the two straps is
recommended (refer to anchor's installation instruction.)
5 5 1 3 Tie -Down Instructions. Because high winds can
occur anywhere, the home should be 'tied down' to the
ground in order to withstand sliding and /or overturning.
See Figures 5 9 through 5.13 for anchor and tie down strap
at applicable wind zones. Vertical ties or straps positioned
at studs are available as an optional item for additional
stability in Wind Zone 1 (standard at Wind Zone 2 and 3)
When provided, attach to ground anchors with 3 150#
minimum rating.
5 5 1 4 Steps to Proper Tie Down. To properly install
ground anchors and tie -down straps for a home, certain
criterias must be established These criterias are as
follows.
1 Wind Zone area where home is to be placed
2. Main I -beam spacing of the home
3 Width and length of the home
4 Distance from top of I -beam to ground
5 Torque reading of the soil.
6 Nominal roof pitch of unit (for doublesection.)
After determining the above criteria.
1 Make sure the distance from the bottom of
the floor to ground level is within allowable range
noted on the tables. Note. Allowable heights
vary based on the wind zone width of the home
and frames main I -beam spacing For example
the Table in the Figure 511 would allow 42'
maximum height from ground for 28' double
Set -Up Manual Page 20
section in Wind Zone 2 with 75 5' I -beam
spacing
2. Based on your wind zone, space the anchor
and straps per Tables in Figure 5 9 through 5 13
Note. Homes with roof pitch higher than 4/12
(roof slope in excess of 20 degrees) may require
additional tie downs. See addendum to
installation instructions for this option
3 Determine the correct soil anchors to be
used. An anchor soil test probe is required to
test the soil where the home is to be set. The soil
test probe looks like a long drill bit with a fitting at
the top which accepts a torque wrench The
torque required to turn the probe when the probe
reaches the desired anchor depth is measured
The anchor manufacturer provides a chart
relating the measured torque value to the type of
anchor required to provide the desired holding
force. AN INCORRECTLY SELECTED
ANCHOR WILL NOT PROVIDE THE
REQUIRED LOAD RESISTANCE. For example,
assume a torque of 300 inch pounds was
measured at a probe depth of 4 feet. A class 4
soil is indicated from the anchor manufacturer
data. The correct anchor would be identified and
rated for a class 4 soil.
Soil anchors must be installed as directed by the
anchor manufacturer The anchor manufacturer
installation instructions should describe the
correct anchor placement with regard to
direction, water table level and frost line location.
5.5.2. Severe Climatic Conditions.
5 5.2.1 Freezing Climates. Be sure anchor
augers are installed below the frost line During
period of frost heave, be prepared to adjust
tension on the straps to take up slack.
5 5.2.2. Severe Wind Zones. Installing your
home in any zone that requires greater wind
resisting capabilities than those for which it was
designed is not recommended. (See data plate
5 5.2.3 Flood -Prone Areas. Installation of our
manufactured homes in flood prone areas are not
recommended Foundation considerations are
discussed in section 4 3 1 and the FEMA
document referenced in Paragraph 4 4 3
Unconventional anchorage and tiedowns often are
needed in designing and constructing the special
elevated foundations that may be required in flood
prone areas. Consult a registered professional or
structural engineer
5 6 Installation Of On -Site Attached
Structures. Design all attached buildings and
structures to support all of their own live and dead
loads, and to have fire separation as required by
state or local ordinances.
5 6 1 Attached Garages. Attached
garages must be installed according to the
manufacturer's instructions and to all
applicable local codes. They must be
supported independently of the factory-built
portion of the home. Electrical circuits in
garages should be provided with ground fault
interruption.
5 6.2. Porches. Site constructed porches
must be constructed and inspected according
to applicable local building codes. They must
be supported independently of the factory-
built portion of the home
5 6 3 Steps, Stairways and Landings.
Steps, stairways and landings must be
constructed and inspected according to
applicable local building codes.

the home must have non closing vents
located at or near each corner and as high as
possible to cross ventilate the entire space
under the home Open vent area must be
equal to at least one square foot for every 150
square feet of the home's floor area, and this
area must be further increased when insect
screens, slats, etc. are used over the open
vent area. In freezing climates, install skirting
so as to accommodate 1 2 inches of frost

6. Chapter 6 Installation of
Optional Features
6.1 Awnings And Carports. Choose free standing
products with columns to support their weight.
6.2. Accessory Windows. Install accessory windows
or components with the installation materials
supplied, and follow the manufacturer's installation
instructions.
6 3 Miscellaneous Lights And Fixtures.
NOTE: Circuits must be turned off to eliminate the
risk of shock.
Some exterior lights, ceiling fans and chain -hung
fixtures may not yet be installed when the home is
delivered. All of these fixtures must be grounded
by a fixture- grounding screw or wire. For chain
hung fixtures, use both methods. When fixtures
are mounted on combustible surfaces such as
hardboard, install a non combustible ring to
completely cover the combustible surface exposed
between the fixture canopy and the wiring outlet
box. If siding has not been installed at a fixture
location, remove the outlet box and install the
siding with a hole for the outlet box. Then reinstall
the outlet box and proceed as for other fixtures.
6 3 1 Exterior Lights. Remove the junction box covers
and make wire -to -wire connections using wire
nuts. Connect wires black to black, white to white
and ground to ground. Caulk around the base of
the light fixture to ensure water tight seal to the
sidewall. Push the wires into the box and secure
the light fixture to the junction box. Install the light
bulb and attach to the globe Refer to Figure
6.1(a).
6 3.2. Ceiling Fans. Follow manufacturer's installation
instructions. To reduce the risk of injury install
ceiling fans with the trailing edges of the blades at
least 6'4 above the floor (see manufacturers
instructions) If no instructions are available,
connect the wiring as shown in Figure 6 1(b) (max.
35# ceiling fan)

6 3 3 Whole House Ventilation. Your house is
equipped with one of the following to introduce outdoor
air to interior environment.
A) Fresh air through furnace. (Philips Ventline)
How it works:
When the furnace air circulator is ON a negative
pressure (suction) is created in the furnace plenum.
This suction draws in fresh air which is mixed with the
return air from the room, and distributed through the
home duct system. The fresh air supply to your
home may be energized at any time by switching the
furnace control (or thermostat control, if so equipped)
to ventilation.
B) Fresh air by an exhaust fan.
How it works:
Inside air is exhausted outside by a mechanical fan
allowing fresh air in through the louvered grill installed
in exterior wall. Exhaust fan is operated by a manual
switch.
6 4 Telephone And Cable TV CARELESS
INSTALLATION OF THE TELEPHONE AND CABLE
TELEVISION LINES MAY BE HAZARDOUS. The
walls and floors of your manufactured home contain
electrical circuits, plumbing and duct work. Avoid
contact with these home systems when drilling
through and placing cables within these cavities. Only
trained professionals should handle such work.
FAILURE TO FOLLOW THESE INSTRUCTIONS
MAY RESULT IN SERIOUS PERSONAL INJURY
OR DEATH. Figure 6.2 shows one procedure for
telephone crossover connections in multi- section
homes.

7 Chapter 7 Preparation of
Appliances
71 Clothes Dryer Vent. Your clothes
dryer must exhaust to the exterior of the home,
or of any perimeter skirting installed around it,
through a moisture -lint exhaust system, as
shown in Figure 7 1 IMPORTANT DO NOT
LET THE EXHAUST SYSTEM END UNDER
THE HOME WHERE EXCESS MOISTURE OR
FLAMMABLE MATERIAL CAN ACCUMULATE.
Install a flex duct after the home is set up at the
site. The access for the dryer vent is located
under the home in the bottom board at the dryer
location (bottom board is taped and marked with
paint or colored tape for access). Hold the duct
in place with metal straps spaced 2' on center
secured to the bottom of the floor joists or frame.
Vent openings are located in either the wall or
the floor After the duct is installed, seal the
openings, both inside and outside. Follow the
dryer manufacturer's instructions for installing
the exhaust system.
If your home did NOT come equipped for a gas
dryer remember that installing one requires
substantial alteration to the home. You must
provide gas supply piping and adequate venting
as specified by the gas dryer manufacturer
Only a trained and experienced person should
install a gas dryer Cutting major structural
elements (such as rafters or floor joist) to allow
for gas dryer installation is not permissible
Home manufacturer is not responsible for any
weakening of the home's structural soundness
resulting from dryer installation.
NOTE. Some dryer manufacturers require that
metallic duct be connected to the dryer and
vented through floor and or sidewall.
7.2. Comfort Cooling Systems. Only
qualified personnel may install any comfort
cooling system not provided with the home.
Follow the manufacturer's installation
instructions and conform to all local codes.
7.2.1 Air Conditioners. The air distribution
system of this home has been designed for a
central air conditioning system. Equipment you
install must not exceed the rating shown on the
home's compliance certificate.
Set -Up Manual Page 29
The home's electrical distribution panel may
contain optional factory installed circuits (Figure
7.2) for air conditioning. The maximum full load
amperes draw for the desired air conditioning
unit must not exceed the circuit rating shown.
On the other hand, electrical circuits within the
home may NOT have been sized for additional
load or non factory- installed air conditioning and
a separate outside electrical supply may have to
be provided.
Any field- installed wiring beyond the junction box
must include a fused disconnect located within
sight of the condensing unit. The maximum fuse
size is marked on the condenser data plate.
Local codes will determine the acceptability of
the air conditioning equipment, rating location of
disconnect means, fuse type branch circuit
protection, and connections to the equipment.
A coil air conditioning units must be compatible
and listed for use with the furnaces in the home.
Follow the air conditioner manufacturer's
instructions.
If a remote (self- contained, packaged) air
conditioner (cooling coil and blower located
outside the home, Figure 7 3) is to be connected
to the heating supply duct, install an automatic
damper between the furnace and the home's air
duct system, and another between the remote
unit and the home's air duct system. Secure the
duct system leading from the remote unit to the
home and do not allow it to touch the ground.
Insulate ducts with material of thermal
resistance (R) no less than 4 and a perm rating
of not more than 1 perm. Connect the duct
carrying air to the home to the main duct at a
point where there are approximately as many
registers forward of the connection as there are
to the rear Locate the return air duct in the
center of the home.
Do not cut or damage floor joists. Return air and
supply ducts are sized to fit between floor joists.
Replace insulation removed during the
installation, and seal the bottom board around
the duct connection.
Direct all condensation runoff away from the home by
connecting a hose to the equipment runoff outlet or
other means specified by the equipment
manufacturer
7.2.2. Heat Pumps. Install heat pumps according
to the heat pump manufacturer's installation.
7.2.3 Evaporative Coolers. Install a roof mounted
cooler following the manufacturer's instructions.
7 3 Fireplace Chimneys And Air Inlets.
Fireplaces require on -site installation of additional
section(s) of approved, listed chimney pipe, a spark
arrestor and a rain cap assembly See Figure 7 4
7 3.1 Minimum Extensions Above Roof To
assure sufficient draft for proper operation, extend the
finished chimney at least 3' above the highest point
where it penetrates the roof and at least 2' higher than
any buiilding or other obstruction located within a
horizontal distance of 10' If the site has obstructions
extending higher than the home's peak within 10' of
the chimney the installer may have to provide an
additional section of chimney pipe if required by local
codes.
7 3.2. Required Components. The required
components of a correctly installed chimney are as
shown in Figure 7 4
FIGURE 7 1 DRYER
EXHAUST SYSTEM
Dryer dropout tube
Flexible Duct Installed at Site
CAUTION: INSTALLATION OF
THE EXHAUST SYSTEM MUST
BE IN ACCORDANCE WITH THE
DRYER MANUFACTURER'S
INSTRUCTIONS.
7 3 3. Assembly And Sealing Sequence.
Assemble and seal your fireplace chimney in
accordance with the fireplace manufacturer's
instructions supplied with the home. Avoid cutting
any roof trusses or floor joists when installing chimney
pipes or combustion air intakes. Carefully seal all roof
penetrations to avoid leakage. Periodic inspections
and resealing of all roof penetrations are required.
7 3.4 Combustion Air Duct Inlets. Combustion
air intake ducts end just below the bottom covering of
the floor You must extend them to the outside when
your home has a basement or crawlspace. These
added ducts are not supplied, but may be purchased
at your local hardware store. The fireplace

7.5 WATER HEATER Note. Your Water Heater is equipped with a pressure and temperature
relief drain and a separate drain for the pan under the water heater These drains are extended to
the bottom of your home upon final installation These drain pipes MUST be directed to exterior of
home. In case of installation of your home on a basement, extend the drain down to your
basement drain Refer to your water heater installation manual for additional information
7 6 WHOLE HOUSE VENTILATION. Your home is equipped with a system to introduce outdoor
freshness to interior environments It works in conjunction with the furnace blower and existing
duct system and is able to work independently when the heating and cooling system is off Fresh
air is a cost effective way to substantially improve air quality and help control attic condensation in
your home. It is encouraged to operate the WHOLE HOUSE VENTILATION system whenever the
home is occupied.
How it works. The home's Thermostat is the control device for selecting continuous
Whole -House Ventilation When the Thermostat is in the 'WHOLE -HOUSE VENTILATION'
position the unit blower will operate continuously independent of COOL or HEAT modes When
the furnace blower is operating, a negative pressure (suction) is created in the furnace plenum
This suction draws in fresh outdoor air which is mixed with the homes return air then distributed
through the home duct system When HEAT or COOL modes are selected, the fresh outdoor air
and home return air are conditioned prior to being distributed throughout the home
8 Chapter 8 Utility System
Connection and Testing
8 1 Proper Procedures. Consult local, county or state
authorities before connecting any utilities. Only
qualified service personnel, familiar with local codes
and licensed where required, should make utility
connections and conduct tests.
8.2. Water Supply
8.2.1 Maximum Supply Pressure and Reduction. The
water systems of your home were designed for a
maximum inlet pressure of 80 psi. If you are
located in a water district where the local water
supply pressure exceeds 80 psi, install a pressure
reducing valve.
8.2.2. Connection Procedures.
8.2.2.1 To Supply Mains. Connect the home's water
system to the water source through the inlet located
under the house, usually below the water heater
compartment. A tag on the side of the home marks
its location. The connection is via a single 3/4 inch
inlet beneath the home. A master shut -off full flow
valve must be installed in the water supply line
adjacent to the home, this valve should be a full port
gate or ball valve with threaded or solder joints.
After removing the aerators from all the faucets,
open all the faucet valves and allow the water to run
for 15 minutes. This should remove any foreign
particles left in the line that might cause an
unpleasant taste or become lodged at faucet
washers and cause dripping faucets.
8.2.2.2. Remove the shipping caps from the crossover
water line connectors, provided with the home, and
install as shown (see Figure 8.2).
8.2.3 Freezing Protection.
8.2.31 Necessity In areas subject to subfreezing
temperatures, protect exposed sections of water
supply piping, shut -off valves and pressure
reducers, and pipes in water heater compartments
with uninsulated doors, from freezing. Otherwise,
burst pipes and costly damage may result.
8.2.3.2. Use Of Heat Tapes. Heat tapes (either automatic
or non automatic) can protect exposed plumbing
from freezing. USE ONLY HEAT TAPES LISTED
BY A NATIONALLY RECOGNIZED TESTING
LABORATORY FOR USE WITH
MANUFACTURED HOMES AND INSTALL THEM
ONLY IN ACCORDANCE WITH THE
MANUFACTURER'S INSTRUCTION. Plug the 3-

Homes. If the home is to be left
unheated in cold weather drain the water
lines and blow them clear with
compressed air to prevent damage from
freezing.
8.2.4 Testing Procedures. Even though the
water system was tested at the factory it
must be rechecked for leaks at the
installation site. Close all water faucets,
spigots and stool tank float valves, and
use the following procedure
8.2.4 1 Hydrostatic. Be sure the water heater
tank is full of water Pressurize the
system with water at 100 psi, and then
isolate it from the pressure source. The
system must hold this pressure for at
least 15 minutes without any loss. If the
pressure falls off re- pressurize the
system and locate and correct leaks.
8.2.5. Anti Siphon Frost -Proof Sill Cock (Faucet)

8.2.5 4 Position siding wedge between faucet and side of
home.
8.2.5 5 Insert shaft of faucet through hole provided in sid
of home from outside.
8.2.5 6 Position faucet so the outside spout is pointing
down and in a slightly downward angle to the
outside (so it will drain properly)
8.2.5 7 Secure faucet to side of home with two (2) #8 or
#10 wood screws (provided) Make sure that
putty tape is between faucet mounting flange and
side of home to provide weatherproof installation.
8.2.5 8 Remove plug from end of factory installed tubing.
8.2.5 9 Thread on end of factory installed tubing to end of
faucet tightly
8.2.5 10 Pressurize water tubing system with air to 100
PSI and hold for 15 minutes. Check field installed
connection at exterior faucet.
8.2.5 11 Remove 100 PSI air from system and fill with on-
site water and again check field installed
connection for water leak.
Replace access panel, cover etc. making sure
the insulation is positioned between faucet/tubing
and access panel cover
8 3. Drainage System.
8.3.1 Assembly And Support. If portions of the
drainage system were not installed at the factory
all materials and diagrams required to complete it
have been shipped as loose items in the home.
Assemble the drainage system following these
specific instructions and diagrams. Start at the
most remote end and work toward the outlet,
supporting the piping with temporary blocking to
achieve the proper slope (see Paragraph 8 3.2)
When the entire system has been completed,
install permanent drain line supports at 4 on
center as shown in Figure 8 3
8.3.2. Proper Slopes And Connector Sizes. Drain
lines must slope at least 1/4 fall per foot of run
unless otherwise noted on the schematic diagram
(see Figure 8 4)
Exception: 1/8' fall per foot is allowed when a
cleanout is installed at the upper end of the run.
Connect the main drain line to the site sewer
hookup using an approved elastomer coupler

drain line crossovers as shown in Figure 8 6
8.3 4 Solvent Welding Procedures. The solvent
cement used to connect drain lines must be
compatible with the pipe installed in the home.
Follow the manufacturer's instructions on the
container
8.3 5 Protection From Freezing. Fittings in the
drainage system subject to freezing, such as
P -traps in the floor have been insulated.
Replace this insulation if removed during
assembly or testing. Insulate drain lines
installed below the bottom board in areas
subject to freezing as shown in Figure 8.7 If
the home is to be left unheated in cold
weather pour an approved antifreeze into P
traps at all fixtures and stools.
8 3 6 Flood Level Test Procedure. You must
conduct a flood level test on the completed
drainage system before connecting it to the
site sewer With the home in a level position,
all fixtures connected, and all tub and shower
drains plugged, connect the drainage piping
system to the site water inlet and fill the
system with water to the rim of the toilet bowl
through a higher fixture. Release all trapped
air Allow the system to stand at least 15
minutes. Check for leaks. Drain the system.
Plug all fixtures, sinks, showers and tubs and
fill with water Release the water in each
fixture simultaneously to obtain the maximum
possible flow in drain piping. Check all P -traps
and the drain system for possible leaks.
Repair any leaks and retest.
8 4 Gas Supply
8 4 1 Type Of Gas System Furnished With Home.
All gas appliances in this home including the
heating system, are equipped for natural gas.
If LP gas is to be used as the gas supply
instead, a qualified service person must
convert the appliances to LP gas following the
instructions provided by each appliance
manufacturer
8 4.2. Proper Supply Pressure. THE GAS PIPING
SYSTEM IN YOUR HOME HAS BEEN
DESIGNED FOR A PRESSURE NOT TO
EXCEED 14 OF WATER COLUMN (8 OZ.
OR 1/2 PSI) IF GAS FROM ANY SUPPLY
SOURCE EXCEEDS OR MAY EXCEED
THIS PRESSURE, YOU MUST INSTALL A
PRESSURE REDUCING VALVE. To operate
gas appliances safely and efficiently do not
exceed the design pressure limitations. For
natural gas systems, the incoming gas
pressure should remain between 6' and 8' of
water column. For LP gas systems, the pressure should
lie between 12' and 14 of water column

8.5 Heating Oil Systems. Homes equipped with oil
burning furnaces must have their oil supply
tankage and piping installed on site. These items
are not supplied with your home. Consult the oil
furnace manufacturer's instructions for proper
pipe sizing and installation procedures. ALL OIL
STORAGE TANK AND PIPING INSTALLATIONS
MUST MEET ALL APPLICABLE LOCAL
REGULATIONS AND SHOULD BE MADE ONLY
BY EXPERIENCED QUALIFIED PERSONNEL.
8 6 Electricity A large enough power supply must
be available at the site An inadequate power
supply may result in improper operation of and
possible damage to, motors and appliances. It
may also increase your electricity costs. The
current rating in amperes of your home can be
found on the tag located outside next to the
feeder or service entrance and also on the
electrical distribution panel.
8 6 1 Description And Rating Of Housing Wiring.
Your home is designed for connection to an
electrical wiring system rated at 120/240 volt AC
PROPER AND SAFE CONNECTION DEPENDS
ON THE TYPE OF SUPPLY SYSTEM YOUR
HOME IS EQUIPPED WITH The connection to
this home requires feeder wiring at the site. The
following paragraphs describe the wiring and
grounding of electrical feeders; if your home is
equipped with a service meter base, skip directly
to Section 8.6 3 4
8 6 1 1 Proper Feeder Wiring And Junction Box
Material And Size. The main breaker and the
label on the electrical distribution panel give the
feeder current capacity and amperes. Using this
information, determine the required feeder size
from the tables at Figures 8 9 and 8 10 These
sizes are based on an ambient temperature of
86 F and do not take voltage drop into
consideration.
8.6 1.2.Overhead Feeders. Homes equipped with
overhead (mast weatherhead) feeder entrances
contain all necessary conduit to the electrical
distribution panel. However you must install
feeder conductors (not provided) on site. Refer to
Figure 8 9
8.6 1 3. Underside Feeders. Homes with an under the -floor
entrance come with a permanently- attached conduit
raceway that runs from the electrical distribution panel
to a point under the floor Install an approved conduit
panel to a point under the floor Install an approved
conduit fitting or junction box at the termination point.
Refer to Figure 8.10
8.6.2. Grounding Of Homes With Feeder Connections.
8 6.2.1 Necessity The home must be grounded properly to
protect the occupants. The only safe and approved
method to ground your feeder connected home is
through the grounding bar in the electrical distribution
panel. This bar grounds all noncurrent carrying metal
parts of the electrical system at a single point.
8 6.2.2. Procedure. The ground conductor of the power supply
feeder cable connects the grounding bar to a good
electrical ground. Follow the feeder connection
procedures described in 8 6 3 1 8 6 3.2, or -8 6 3.3 to
achieve proper grounding.
Insulate the grounded circuit conductor (neutral or white
wire) from the grounding conductors (green wires) and
from equipment enclosures and other grounded parts.
Insulate neutral circuit terminals in the distribution panel
board and in ranges, clothes dryers, and counter
mounted cooking units from the equipment enclosure.
Bonding screws, straps or buses in the distribution
panel board or in appliances should have been removed
and discarded at the manufacturing facility (Bonding
screws, straps, etc. in appliances must be removed on
appliances to be installed by persons other than the
manufacturer) You may provide the required continuity
of ground between sections of multi- section homes by
bolting outriggers together When the outriggers or
other overlapping metal joints of adjoining units are not
bolted together on houses with shingle roofs and non-
metallic siding install a ground wire connection between
the chassis. This bonding connection is commonly
made with a #8 AWG bare copper wire or other
approved positive connection between parts (Figure
8.11) using approved grounding lugs with bolts, star
washers and nuts, or self- tapping screws that are
shipped with the home.
8.6.2.3. Unacceptable Methods Of Grounding Homes.
Grounding to a rod, a water pipe, or through the home's
hitch caster will not satisfy the important grounding
requirement. NEVER USE THE NEUTRAL
CONDUCTOR OF THE FEEDER CABLE AS A
GROUND WIRE. DO NOT GROUND THE NEUTRAL
BAR IN THE ELECTRICAL DISTRIBUTION PANEL.
8 6 3 Connection Methods. Connections should be made
only by a qualified electrician. Connect homes
equipped for 100 amp or greater service by one of the
three following methods.
Set- Up Manual Page 36
8 6.3 1 A Feeder Cord. Your home may be equipped
with a permanently- connected 50 amp feeder
cord stored in a compartment under the floor If
so, it is ready to be plugged into a 5 amp, 3 -pole,
4 -wire, 120/240 volt grounding service receptacle
after electrical tests have been completed (see
8.6.6) WARNING: MANY HOMES ARE
EQUIPPED FOR 100 AMP OR GREATER
SERVICE. UNLESS YOUR HOME IS
EQUIPPED FOR ANY 50 AMP SERVICE, DO
NOT ATTEMPT TO USE A FEEDER CORD OR
'PIGTAIL CONNECTION
8 6 3.2. Mast Weatherhead Feeder The routing,
connection and support of the service drop must
meet local codes. Homes equipped this way
contain all necessary conduit to the electrical
distribution panel. However feeder conductors
(not provided) must be installed on site in
accordance with Figure 8 9 If the masthead is
located above the roof overhang, allow a
minimum 8' clearance above all roof points the
conductors pass over There are two exceptions
to this rule: 1) The vertical clearance may be
reduced to 3' if the roof has a minimum slope of 4
in 12; and 2) The vertical clearance may be
reduced to 18' if no more than 4 of service -drop
conductors pass above the roof overhang, and if
they terminate at a through- the -roof raceway or
approved support. A minimum clearance must
also be provided from the final grade to the
service -drop conductors. This measurement
may vary from 10' to 18' depending on the types
of traffic anticipated below the service drop (refer
to the National Electric Code). Unless
impractical, locate service heads above the point
of attachment of the service -drop conductors and
make them rain tight. If individual conductors do
not extend downward, form drip loops.
8 6 3 3 Underside Junction Box Feeder A raceway
from the main panel board to the underside of the
home allows for installing an approved junction
box or fitting, which must be used to connect it to
the supply raceway (see Figures 8 10 and 8 12)
Install properly -sized conductors from the main
power supply to the panel board Refer to Figure
8.10 for conductors and junction box
requirements. The homeowner or installer must
provide the supply connection including the
feeder conductors, junction box and raceway
connectors. Protect conductors emerging from
the ground from a minimum 18' below grade to 8'
above grade, or to the point of entrance to the
home. The distance measured from the top
surface of a buried cable, conduit or raceway to
the finished grade must meet minimum burial
requirements outlined in the National Electric
Code. Use a moisture -proof bushing at the end
of the conduit from which the buried cable
emerges.
8 6 3.4 Service Equipment Meter Base. Either an
overhead or underground entrance may be
provided. The exterior equipment and
enclosure must be weatherproof and
conductors must be suitable for use in wet
locations. When a meter is provided on the
home, connect the neutral (white) conductor
to the system grounding (green) conductor on
the supply side of the main disconnect. Refer
to Figure 813 for typical meter base
installation and on method of grounding the
service equipment. The homeowner must
provide the grounding electrode conductor(s).
The grounding electrode shall be an 8' length
of 1/2' diameter copper rod or 3/4' galvanized
steel pipe. Drive it into the ground at least 12'
below the surface and 2' from the foundation,
or bury it horizontally in a 2 1/2' deep trench.
Connect the grounding conductor wire to the
grounding electrode with a grounding clamp
For added protection homes with metal
frames or siding should be connected to earth
by means of an additional bonding wire to
underground metallic water pipes, ground
rings, additional ground rods, etc. to prevent
buildup of hazardous voltages.
8 6 4 Crossover Connections. Refer to Figure
8 14 for typical crossover wiring connections,
for multi- section homes (located along the
centerline between sections) Crossover
locations can be distinguished by metal
junction boxes or access cover panels.
Remove these panels and connect the
enclosed wires as illustrated. Some
crossover connectors plug together and do
not require junction boxes.
8.6 5. System Test Procedures And Equipment.
8 6 5 1 Pre Connection Tests. Conduct both of the
following tests before any electrical power is
supplied to the home.
8 6 51 1 Circuit Conductor Continuity Conduct a
continuity test by placing all branch circuit
breakers and switches controlling individual
outlets in the 'on' position. The test should
give no evidence of a connection between
any of the supply conductors (including the
neutral) and the grounding circuit. You may
use a flashlight continuity tester
8.6 5 1.2. Grounding Continuity Using a continuity
tester test all noncurrent carrying metal parts
to assure continuity to ground. The parts to
be checked include: appliance enclosures,
including fans; fixture enclosures and
canopies; metal siding and roofs; metal water
Set- Up Manual
8.6 5.2. Post Connection Tests. Conduct the
following three tests after turning on the main
circuit breaker and each individual circuit
breaker CAUTION: Allow the water heater
to fill completely before activatina the water
heater circuit. Failure to do so will cause the
water heater element to burn out. an event
not covered by the warranty
8 6 5.2.1 Polarity And Grounding Of
Receptacles. With receptacle and lighting
circuits energized check the polarity and
grounding of each 120 -volt receptacle and
light socket using a polarity tester capable of
determining an incorrect wiring configuration.
A conversion device may be required to test
various fixture bulb sizes and outlet
configurations. Investigate any indication of
reversed polarity open grounds or shorts and
correct it.
8 6 5.2.2. Ground Fault Circuit Interruption
(GFCI). Make certain that all receptacles
requiring GFCI protection are in fact on the
correct circuit(s) Check each ground fault
circuit interrupter device by pushing the test
button to determine if the power route to all
receptacles requiring GFCI protection has
been interrupted, and follow the manufacturer's
instructions. Replace any GFCI that does not
operate properly
8 6 5.2.3. Operational Checks. Check all light
fixtures by placing a bulb in the socket and
turning the switch on and off Using a pigtail
light, check all 240 volt receptacles to
determine if both legs of the circuit are
powered. Check all 120 volt receptacles to be
sure that each is operational. Switched
receptacles require the switch to be turned on
and off. It is not necessary to check
appliances, but their power sources must be
assured Failure of electrical wiring or fixtures
requires repair and re- testing.

supply and gas lines; metal ducts (except foil
covered insulated ducts); and the home's
frame. On multi- section units, perform this
test only after
completing all electrical and bonding
connections between the units. NOTE.
Groundina is not reauired on the metal inlet of
a plastic water system or on olumbina fixtures
such as tubs. faucets. shower risers. and
metal sinks when they are connected only to
plastic water and drain oioina.

Set -Up Manual Page 44
10 1 Relocation of Home. If it is necessary to move your
home, have it moved by a professional manufactured
home mover making sure he uses enough
temporary wood blocking, and check the following
items:
10 1 1 New Zones. Check the roof and wind load and the
temperature requirements at the new location. If the
new requirements are greater than those shown on
your home's compliance certificate check the cost of
adapting the home before moving. Otherwise any
resulting damages will not be covered under your
warranty and you may be held liable for any failures.
Check with home's plant of manufacturing, your
retailer or a qualified manufactured home mover about
making these home improvements.
10 1.2. Tires and Axles. Replace any removed tires or axles
as required by the manufacturer Be sure that tires are
inflated correctly have at least 1/16' tread, and do not
have any cracks or splits. Check and repair bearings
and brakes as necessary
10 1 3 Appliances. Secure appliances to prevent movement
during transportation.
10 1 4 Dust Caps. Place dust caps on the ends of all pipe
connections.
101 5 Blocking During Storage. Any home placed in
storage, including those on sales lots, must be
immediately blocked under each I -beam, both at the
rear of the home and midway between axles and hitch,
to prevent excessive deflection and possible structural
damage.
101 6 Transit of Furniture and Belongings Substantial
damage may result if furniture, personal belongings,
set -up materials or other items are stored in the home
during transit. TRANSIT DAMAGE IS NOT COVERED
UNDER YOUR WARRANTY
10 1 7 Multi- Section Homes. Re- install temporary structural
supports and bracing materials before moving the
home Cover open sides of sections with weather
proof material such as 6 mil plastic sheeting. After the
sections have been separated, secure 2' x 6' shipping
braces at the front end and in the axle area. Place
ridge beam supports in open areas or at a maximum of
4 on center
10 1 8 Multi- section homes with stairwell must have the
stairwell cutout reinforced for transportation. Locate
the factory installed framing plug and fasten to floor
framing with #8 x 3' wood screws. If the factory
installed stairwell plug cannot be located, construct a
temporary stairwell plug with 2 x 6's #3 SPF at 24
o c. with 5/8' APA rated decking. Fasten all framing
members with (3) 16d nails and decking with 10d
nails 6' o.c.
