CHAPTER 1 - INTRODUCTION
1.1 How to use this manual. This manual contains. detailed
installation instructions, including specifications and
procedures for erection and hookup of your manufactured
home It has been written in an objective .and easy-to-
understand manner so it can be understood by people without
extensive technical training. It discusses the set-up of
the home from preparing the site through final inspection
It includes many tables and figures giving important data
for .proper setup. Careful adherence to this manual by the
homeowner and installation crew, and consultation with a
registered professional or structural engineer in those
unusual circumstances it does not cover, will assure you of
a quality, safe and affordable home for many years to come
1.2 Pre-installation consideration. Prior to locating or
relocating your home, contact the local authority having
jurisdiction for installation to see if permits for such
procedures as blocking, anchoring, or utility connections
are required Inspections may be required during
installation On private property, zoning or development
covenants may apply and should be taken into consideration
NOTE: Preparation of the site, when accomplished by other
than the home installer, may not be in accordance with these
instructions.
1.3 safety. Only trained crews should install the home
Installers should follow the safety instructions provided in
this manual
THIS HOME WEIGHS SEVERAL TONS
USE ENOUGH TEMPORARY WOOD BLOCKING TO SUPPORT THE HOME
DURING SET-IIP. No one should be allowed under the home
unless it is securely in place, even if it is not moving
1.4 Consumer information card Fill out the CONSUMER
INFORMATION CARD and return it to Karsten Homes, so that you
may be notified of revised instructions or new products

2
CHAPTER 3 - SITE PREPARATION
3.1 Location and Layout
3 1. 1 Use of zone maps Your home is designed for certain
weather conditions and roof loads (See zone maps,
permanently attached near home's main electrical panel (or
other location) and in Figure 3 1 of this manual. ) Do not
site or relocate. your home in a zone requiring greater
wind, roof load,1 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 of 40 psf may be sited in the southern roof load
zone.
3 1.2 Access for transporter. Before attempting to move your
home to the installation site, be sure the transportation
equipment can get through Remove any overhanging
branches and raise any overhead wires Special
transportation permits may be required from state, county
or city officials
3.1 3 Encroachments and setback distances. Obey local laws
regarding encroachments in streets, yards and courts, and
permissible setback distances from property lines and
public roads. Consider future additions, such as awnings
and screen rooms
3.1.4 Issuance of permits Be sure that all necessary local
permits have been obtained and fees paid.
3 2 Boil Conditions
3 2. 1 Requirements. �To help prevent settling of your home, site
it on firm, undisturbed soil or fill compacted to at least
90% of its 1mum relative density. Installation on
loose, uncompacted fill 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
pressures 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
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. 6
3 4 2 Elimination of depressions Grade the homesite to permit
water to drain from under the home
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
3.5. 1 Importance If the crawl space under the home is to be
enclosed with skirting or other material, a vapor retarder
that keeps ground moisture out of the home shall be
emplaced
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 conditions permit placement
of footings at grade level, place the sheeting directly
beneath them

CHAPTER 4 - FOUNDATIONS
4.1 Piers
4.1.1 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
4.1 2 Acceptable types Piers may be concrete blocks or pressure-
treated wood, capped .and shimmed with wedges, or adjustable
manufactured metal or concrete devices (see Figure 4 1)
Adjustable devices are more accurate. Manufactured piers
should be listed and labeled for the required load capacity
4.1.3 Design requirements
4.1.3.1 Load-Bearing Capacity. The load that each -pier must
li carryi 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 multisection homes
See Tables 4 1 and 4.2 for pier capacities
Manufactured piers must be rated at at least these
capacities, and locally-constructed piers must be
designed to transmit these loads safely (see
4.1 3.2)
t
4.1.3.2 Configuration Figure 4 1 shows, the recommended
arrangement of concrete block piers constructed on-
sitel. Concrete blocks- should have nominal
-dimensions of at. least 6" x 16" They must be
stacked with their hollow cells aligned vertically
When piers are constructed of blocks stacked side-
by-side, every layer should be at right angles �o
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 may be of solid masonry or pressure treated
lumber, at least 4" thick, or of steel, 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 lumber shims to level the home and fill any gaps
between the base of the I-beam and the top of the
pi r cap Always use shims in pairs (see
7
Figure 4 1) Drive them in tightly so they do not
occupy amore than i" of vertical space When the
space to be shimmed is less than the minimum
thickness of available caps or concrete blocks,
dimension lumber may be used under the caps
Select manufactured pier heights so that their
adjustable risers do not extend more than 1" when
finally positioned (or beyond the limits specified
by the manufacturer)
All piers must rest on footings (see paragraph 4 2)
that either extend below the frost line or are
otherwise protected from frost effects, and are
placed on either undisturbed soil or compacted fill
4.1.4 Design procedures
4.1.4.1 Piers less than 361, high. You .may construct piers �
less than 36" high out of single, -open or closed-
cell concrete blocks, 8" x 81" 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 required Manufactured piers should
be listed and labeled
4.1.4.2 Piers 361' to Solo high. Construct all piers between
36" and 80" high, out of double, interlocked
concrete blocks (see Figure 4.1) Mortar will not
be required
4..1.4.3 Piers over Sol# 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
4.1.5 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 (single- or
multisection) , and other factors such as the locations of
doors or other openings and heavy pieces of furniture
ti
8
4 1 5 1 Bingle-section homes. Figure 4 2 shows the
recommended location and spacing of -piers for your
single-section home.
4.1.5.2 Multiseotion homes. .Figure 4.3 shows the
recommended location and spacing of piers for your
multisection home
4.2.5.3 Under doors and heavy furniture. Place piers on
both sides of sidewall exterior doors and other
sidewall openings 4 ' or wider (such as recessed
entries; bay windows, and sliding glass doors) ,
under porch posts, fireplaces and wood stoves, and
under the expected locations of heavy pieces of
furniture such as pianos, organs, waterbeds, etc
4.2.5.4 Maltisection Ridgebeam support Piers. In addition
to piers located along main beams. and at exterior
openings, piers should be placed at each ridgebeam
column location These piers are necessary to.
transfer concentrated roof loads safely to the
ground) The location of these piers are shown by
either dimensioned drawings provided with your home
or by paint marks or decals on the bottom side of
the center line floors See Figure 4 4
The influence spans are the sums of adjacent opening
spans See Figure 4 5 for an illustration of the
method for determining these spans See Table 4 2
for the minimum pier capacity
4.2 Footings. Support every pier with a properly designed
footing, as follows
4.2.1 Acceptable types of footings
4.2. 1.1 Coaarete. Footings may consist of precast or
poured-in-place concrete, pads, slabs or ribbons
3 ,000
with a 2s-day compressive strength of at least
psi. Unreinforced footings must have a depth offt
aat
least 1 1/2 times the length of the footing
projection from the pier (See Table 4 3 )
4.2.1.2 Pressure-treated lumber. Two fastened layers of 2"
thick pressure-treated wood planks, with the long
dimension of the second layer placed perpendicular
to that of the first, and cut edges painted or
retreated, may also be used
9
4.2.2. Placement in freezing climates
4.2.2.1 Conventional Footings. To preclude the harmful
effects of ground frost heave, footings should
usually be placed below -the frost line Consult
local authorities to determine frost penetration
4.2.2.2 Floating slab Systems.. When properly engineered by
a registered professional engineer, compatible with
the anchorage requirements of section 5 4, and
accepthble to the local authority having
jurisdiction, "floating slab system" may be used
above the frost line
4.2.3.3 Insulated Foundations. Footings may also be placed
above the frost line when the home is provided with
a perimeter foundation or skirting having insulation
properties sufficient tb ,prevent freezing of the
soil under or adjacent to every load-bearing
component of the foundation and acceptable for this
purpose to the local authority having jurisdiction
Useful design guidelines may be .found in references
4.5 7 and 4 5.8 at the end of this chapter
Insulation systems should be compatible with the
requirement to cross-ventilate the entire space
under the home (see paragraph 5 5)
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 3 for recommended footing sizes for
various pier capacities.
4.3 Special Conditions (See also section 5.4.3)
4.3.1 Flood-prone areas. Karsten Homes does not recommend siting
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 home
design and construction conform to applicable federal, state
and local codes and regulations The FEMA publication listed
in section 4 5 contains design and construction
recommendations
4 3 2 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
tables and special manufacturer's instructions provided with
your home Ventcaps, plumbing vents, gas furnace and water
10
heater stacks, Blend Air systems, etc shall be extended by
retailer or homeowner as necessary to assure proper operation
during high snow depth conditions
4.4 Basement Foundations. Figures 4 6, 4 7, 4 8 and 4 9 show a
typical basement foundation design if you desire .your home
to be placed on a permanent foundation numerous special
construction techniques must be used in the home's setup
These condiderations are contained in these figures
4.5 Important reference documents

CHAPTER 5 - SETUP PROCEDURES
5.1 Moving home to location. Make sure the following items are
completed before placing the home
The site is properly prepared See Chapter 3
All concrete work necessary to setting the home is finished
Utilities are installed or available
Any trenching, for crossover drain lines or for wheels that
will be left in .place, is complete
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. GUERDON
HOMES RECOMMENDS WOOD BLOCKING
5 2 Setup Procedure Instructions
Please Read Carefully
5 2 1 Leveling and Blocking.It is important that these instructions
and precautions are adhered to closely if you are to enjoy
the comfortable, safe and trouble free home- that has been
.designed and built for you The following four items apply
to the set-up of all homes (single-section and multi-section
homes) . Each step should be checked off as it is completed
The set-up crew- should consist of a minimum of two
experienced set-up members
In following the procedures below for set-up, it. is
recommended that your home be installed as close as possible
to the ground as local codes permit, yet still providing a
crawl space for periodic inspection This may require that
wheels and tires be removed and that the ground in the axle
hub and drum area be "dug out" so the drums can be set lower
1 After selecting the foundation system desired, select the
footing area and load capacity from the information
contained in Chapter 4 , Foundations, by relating the
information in Chapter 4 to the structural load zone for
which your home was designed and will be set up in
2 If the support foundation or tiedown types selected
cannot be installed when the home is in its final
Position, these portions of the support foundation systen►
23
must be installed before the home is positioned in its
final desired location For example, ground anchors
required for a tiedown system normally must be installed
before the home is placed in its final position
3 Upon delivery of your new home, and before placing in its
final position, you should inspect both interior and
exterior for possible shipment damage. Any damage should
immediately be reported to your dealer
4 Prior to se,-up of your home, the soil beneath the final
home location should be prepared as outlined on Chapter
3
5.2.2 Bingle Wide set-up Procedure Pier Foundation
1 Position your home in its proper final location.
2 Using an adequate jack at the hitch, "rough" level the
home This is only a "rough" level and not the "final"
1eve1
3 Placing the individual support foundations under the home
in the correct sequence is very important and should be
done as follows Place the first lifting jack under the
chassis' matin beam, just forward, of the front spring
shackle Locate the lifting jack so that a support
foundation can be placed next to the front spring
shackle
4 Position a second lifting jack under the same chassis'
main beam just behind the rear spring shackle
5 Using both jacks uniformly, lift one side of the home and
place a support foundation (using appropriate sized piers
and footings as referenced in Chapter-- 4.) next to the
front spring shackle.
6 Place a second support foundation within 8 feet of the
first or, if necessary, immediately behind the rear
spring shackle On three, four or five axle units where
these two support foundations could be further than 8
feet apart; place a third support foundation between
axles spaced as evenly as possible between the first two
support foundations
7 Place one additional support foundation towards each end
of the chassis ' main beam within 2 feet of the extreme
end of the home
24
8 Lift the opposite side main beam as outlined above and
"rough" level by placing support foundations directly
opposite those placed on the first side
S Complete the "rough" leveling from front to rear and side
to side by adjusting the support foundations as required
10 Evenly .space intermediate- support piers under the main
beams so that the home is supported as required (See
Figure 4 2 )
11 Place additional supports at each side of doors or
openings 4 feet wide or wider
12 Additional support foundations are desirable under
chassis , main beams or floor joists where extra heavy
furniture or appliances are located
13 Make a "final" level adjustment of the home using a
standard bubble level or a manometer type level Work
from front to rear and side to side to obtain "final"
level conditions throughout the home Each individual
Support foundation should be snug and in contact with the
home
14 The tiedourn system must be connected as discussed in
Section 5 4 of these instructions, and in accordance with
the instructions of the tiedown and anchor manufacturer
15 In the event of a slight settlement any time after the
initial installation, releveling can be accomplished by
following the procedures detailed above for "final"
leveling.
16 Install all light shades and light fixtures as needed
17 Connect and test utility systems (electrical, water.,
drain lines and gas lines, as applicable) as detailed in
Chapter 8 (This is a retailer/set-up contractor
responsibility )
18 Check and adjust the entire home for items which may have
become misaligned in transit or during set-up, such as
the following
a- Adjust passage doors to close easily with proper
alignment
b Realign cabinet doors
c Adjust drawers to open and close easily
d Adjust closet doors, aligned and square with walls
e Adjust exterior doors to close easily and be square
with frame, and to lock and unlock easily
f Adjust all windows to open and shut easily
25
g Adjust drapes to operate easily and completely close
h Recaulk over the top of all windows and doors and other
seams as necessary
i Retack any loose moldings, panel connections, and trim
j Retighten "p" trap fittings
19 On some models, it may have been necessary to ship loose
appliance Vent piping to assure the pipe's safe
transportation to the final site Check all appliances
to confirm that all venting is installed per the
appliance installation instructions
20 Install and/or connect all other parts and items shipped
loose with the home
21 Conduct final clean-up operation in the home
22 Your Karsten Home is ready for occupancy
5.2.3 Multivide bet-up Procedure: Pier Foundation
1 Strip all plaistic and wood braces from both units
(weather proof covering and temporary supports) Be sure
all exposed nails and staples are removed
2 Position one7half (usually the heaviest half) of the home
in its proper final location
3 "Rough" level this half of your home as outlined in Steps
2 through 12 of the Single Wide Set-Up Procedures (See
Figure 4 3 for spacing and location of individual support
piers )
4 Place an additional support foundation under the floor
rim joist at leach ridge beam column location (See Figures
4.. 4 and 4 5) .
5 On models with the heat duct crossover in the floor or in
the ceiling, lcheck the mating gasket for proper alignment
and installation
6 Once the first half of the home is in place, a strip of
sill-seal insulation should be attached per Figure 5 1 to
the marriageljoint of the first half The sill-seal
insulation will fill any gaps between the. two halves of
the home and help prevent air infiltration (Sill-seal
provided by others )
7 Position second unit along side the first unit being
careful not to jar the first unit Approximately six
inches or less should separate the floors Bring the two
floors together using jacks or similar devices Draw the
26
floors together tight (at this stage the ceiling will
usually be open at the center)
8 Loosely attach the floors together (See Figure 5 2) .
Predrill holes in the floor rim joist and insert -the lag
screws Do not fully tighten (The optional methods
shown in Figures 5 3, 5 4 and 5 5 may be used, but are in
addition to Figure 5 2 )
9 Starting with the -inside main beam, rough level -the
second floor as detailed in the Single Wide Set-up
Procedure, Steps 2 through 11-
10 Close the gap in the -center of the ridge beam halves by
raising the outside of the second unit Connect the top
of the ridge beam using one of the methods shown in
Figures 5 6, 5 7 or 5 8 It may be necessary to adjust
the ceiling joint flush before installing the
connections. A jack and tee is used to raise whichever
ceiling. is low Start in the front and work through the
home to the rear On homes which have ridgebeam column
supports in only one half, the ridge beams must be bolted
together at each column location See Figure 5 12 for
quantity and location
11 Tighten the lag screws to securely fasten the floors
together
12 Make a final level adjustment of the home using a
standard bubble level or a manometer type level Work
from front to rear and side to side to obtain final level
conditions throughout the home Each individual support
foundation -should be snug and in contact with- the home.
13 a On metal roof homes, install the roof cap with sealant
tape along each side (See Figure 5 8) overlap
approximately two or three inches using sealant tape
between sections Screw roof cap along eachside at
three inches on center Screw cap sections together at
overlap two inches on center Seal along both sides of
roof cap, overlapping joints and all exposed screws
with roof coating Check entire roof and roof jacks
If in doubt, apply roof coating Install exterior
finish pieces on the front and rear of the home to
finish the center joint
b On shingle roof homes, install two layers of 15# felt
along the length of the home's ridge line and tack in
place The felt layers are to be overlapped 4" at each
seam, with the top layer seams offset a minimum of 48"
from the bottom seams Install the top courses of
shingles on each half with 4 shingle nails, positioned
27
5 5/8" above the butt and not in or above the -self-
sealing strip. The nails are to be placed -as required
by the instructions on the. shingle bundle wrapper. Cut
the tabs off of the shingles. to be used..for the, ridge
cap Bend the shingle lengthwise so as to have an
equal -exposure on each balf. of. the ridge Begin at
either end of .the ridge and lay the shingle. over the
top edge and secure it on each side with a nail located
5 1/.2 from the exposed end and 1" up from the edge
Lay the succeeding shingles so as to expose 5"
NOTE: In cold weather, warm the shingles before
bending them; field installed shingles and ridge caps
must be hand tabbed, using an approved tar and sealer.
14 Connect -gas line flex connector (crossover) where
bl
applicae (Sete Figure 8.10 )
15 Connect .,electrical crossover as required with the
material provided. (:See Figures..a 15 )

appliance vent piping to assure the pipe's safe
transportation to the= final site Check all appliances
to confirm that all venting is installed per the:
appliance installation instructions
27 Install and/or connect all other parts and items shipped
loose with the home
28 Conduct final clean-up operation in the home
29 Your Karsten Home is ready for occupancy
5.3 Anchoring Instructions. After blocking and leveling, the
installer should -secure the home against the wind
5.3.1 Number of location of "chore. Select the number and
location 'of straps and anchors from the chart and diagram of
the- appropriate Figure 5 10. Use only listed and approved
ground anchors capable of -resiating at least the minimum
loads given in the chart for the method you select.
5.3 .2 Installation of anchors. Install the anchors at the
locations selected from the appropriate Figure 5 10 ,
following the anchor manufacturer's instructions Install
double-head anchors at all over-the-roof-tie locations Line
up the shaft of each anchor with its strap (see appropriate
Figure 5 11 ) When connecting more than one strap to a
single anchor, line up the shaft of each anchor with the
calculated resultant of combined forces (see appropriate
Figure 5 11 ) You may want to consult a registered
professional or structural engineer to determine the correct
angles for the anchors
29
S.3.3 Strap Tensioning. If your home is releveled at some date
after the initial tensioning of .the anchoring straps, the
straps should be retensioned as specified .in 'the anchor
manufacturer's installation instructions.. Straps .must be
inspected periodically to assure that proper tension is
provided in each strap If straps are found to be loose,
then retensioning of the straps should, be performed
5.3 4 Optional Over-the-Roof Straps. Optional over-the-roof straps
may be used to provide additional stability for single-
sect�6h homes, above and beyond that. from the mandatory frame
tier-downs for Wind Zone 1 Straps and anchors should be
installed per Figures 5 10, and 5 it
5.3.5 severe climatic conditions
5.0..5..1 Frees.inq Climates. Be sure anchor augers are
installed below the frost line During periods of
frost heave, be prepared to adjust tension on the
straps tp take .up slack
5.3.5.2 severe grind .sones Karsten Homes does not recommend
installing your home in an area -known to experience
severe winds, or in any zone that requires greater
wind-resisting capabilities than those for which it
was designed (see data plate)
5.3 5 3 Flood-prone areas Karsten Homes does not recommend
siting manufactured homes in flood-prone areas
Foundation considerations are discussed in section
4 4 1 and the FEMA document referenced in paragraph
4 5 4 ( Unconventional anchorage and tie-down often
are needed. in designing and constructing the special
elevateid foundations that may be required in flood-
prone areas Consult •a registered professional or
structural engineer
5.4 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
5.4.1 Expanding rooms. See specific instructions and illustrations
included with your home
5. 4 2 Attached garages Attached garages must be installed
according to the manufacturer's instructions and to all
applicable local codes They must be supported independently
30
of the factory-built portion of the home Electrical
circuits in garages should be provided with ground fault
interruption See specific instructions and illustrations
included with your home
5.4.3 Porches. Site-constructed porches must be constructed and
inspected according to applicable local building codes
5 4 4 Steps, stairways and landings. steps, stairways and 'landings
must be constructed and inspected according to applicable
local building codes
5.5 Skirting. Skirting installed around the home should have
nonclosing vents located at or near each corner and as high
as possible to cross-ventilate the entire space under the
home. 'Vent free area should be equal to -at least one square
foot for "every 150 square feet of the home's floor area, and
this area should be further increased when insect screens,
slats, et6. are used over the open vent -area. In freezing
climates, install skirting so as to accommodate 1-2 inches of
frost heave uplift to prevent buckling of floors Take care
that rainwater cannot be channeled or trapped between the
skirting and siding

can accumulate. 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
manufacturerls instructions- for-installing the exhaust
system
If your home did .not come equipped with 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
Joists) to allow for gas dryer installation isnot
permissible Karsten homes is not responsible for any
weakening of the home's structural soundness resulting from
dryer installation
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 fora central air conditioning system.
Equipment you install must .not exceed the rating shown on the
home's compliance certificate
The home's electrical distribution panel may contain optional
factory-installed .circuits for air conditioning The-maximum
full load ampere 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 the additional load of 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,
51
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 . furnace 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
7.2) 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) not. 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 Replace insulation
removed during the installation, and seal the bottom board
around the duct connections
Direct all condensation runoff away from the home by
connecting a hose to the equipment runoff outlet or by other
means specified by the equipment manufacturer
7.2 2 Heat pumps Install heat pumps according to the heat pump
manufacturer's instructions
7.2.3 Evaporative coolers. Install a roof-mounted cooler following
the manufacturers instructions In the absence of
instructions, proceed as follows

following the color code scheme of Figure 7 3 using wire
nuts, and replace the cover on the box
Check to be sure a rigid base has been provided to evenly
distribute the cooler's weight over several rafters Tightly
seal all roof penetrations and the boot connecting the cooler
to the roof/ceiling opening to prevent leakage of water into,
and cool air out of, the home
Connect the cooler to an external water supply and attach an
overflow hose to its accumulation pan to route overflow water
away from the home
Do not attach guy wires to roof vents, flues or other items
projecting from the roof To eliminate potential leaks,
52
route guy wires over the side of the home and attach them to
the roof rafter edge rails rather than the roof itself Seal
all fastener penetrations Karsten Homes suggests installing
an insulated lightning protector, grounded directly to earth
7.3 Fireplace and wood stove chimneys and air inlets. Fireplaces
and wood stoves require on-site installation of additional
section(s) of approved, listed chimneyipipe, a spark arrestor
and 'a rain cap assembly. See Figure 7 4.
7.3. 1 ![inimum 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 building or other obstruction
located within a horizontal distance of 10' . If the site has
obstructions extending higher than the home's roof 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

just below the bottom covering of the floor You must extend
them to the outside when your home has a basement or crawl
space These added ducts are supplied, or may be purchased
at your local hardware store The fireplace manufacturer's
instructions for installing combustion air ducts are in the
fireplace/stove or with the chimney parts Do not allow the
combustion air inlet to drop material from the hearth beneath
the home Locate its inlet damper above expected snow level,
as shown in Figure 7 4
7.4 Range, cooktop and oven venting If your home is equipped
with a combination range (cook-top)/grill or oven that
contains its own exhaust system, route the exhaust so that it
does not exit under the home Connect flexible metallic duct
between the elbow protruding from the floor and the
termination fitting, and support it according to the
manufacturer's installation instructions
7 5 Window Air Conditioner Installation Do not plug a window
air conditioner unit into one of your homes lighting or
appliance circuit receptacles The majority of window air
conditioners require that a separate circuit be installed for
si
the connection of the unit See the air conditioner
manufacturer's installation instructions for the electrical
requirements for your specific model The circuits installed
in the home are for standard lighting and small appliance
fixtures only
CAUTION: pse of those receptacles for other
purposes may cause an overload and the
possibility of a potential fire hazard
arises.
The only exception to the above is if there is a separate
circuit installed and labeled in the main panel box as being
for the use of an air conditioner unit All wiring which is
to be installed for an air conditioner unit must be performed
by an authorized electrician and in conformance with all
applicable codes.
7.6 Furnace Deration. If your home is located at 4500 feet or
more above sea level, your gas furnace must be derated for
the altitude. This must be done by a qualified serviceman.
A licensed technician may be required Check with your local
authorities.
CAUTION: Failure to Berate the furnace can cause
the furnace to over-heat, operate poorly
and cause excessive sooting. Dangerous
levels of carbon monoxide could accumulate
in the home.

8.5 1. 1 vaporising (gravity-feed) furnaces Install
oil tanks that feed vaporizing-type oil furnaces so
that oil flows :freely by gravity To achieve
efficient gravity flow, install the tank so that its
bottom is at least 8" above the leve] of the
furnace's oil control and its top is �rithin 8 ' of
the oil control level
8.5 1.2 Gun (pump-fed) furnaces Since the furnace includes
a ruel pump, the tank may be- installed above or
below ground For tanks installed below ground, do
not exceed the lifting capacity of the pump, and
extend the filler neck 1' above grade and provide a
1-1/4" diameter minimum vent pipe extending at least
2 ' above grade
8 5 1 3 Sloping and draining requirahents. Regardless of
the type of oil furnace or the tank location,
install the tank to provide a gradual slope toward
the fill end or drain plug (if so equipped) This
facilitates pumping or draining of water or sludge
8.5.2 Shutoff valve and fuel line filter Inst-all an accessible
and approved manually-operated shut-off valve at the oil tank
outlet Guerdon Homes also recommends installing a suitable
filter in the fuel line near the tank to trap dirt and water
8 5.3 Leak test procedure Before operating the system, check for
leaks in the tank and supply piping Fill the tank to
capacity with fuel and examine all joints in the system for
leakage
a 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

codes Homes equipped this way contain all
necessary conduit to the electrical distribution
panel and feeder conductors 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 drop loops
66
8 6 4 3 Underside junction box feeder. A raceway from the
main panelboard 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. Install properly-sized conductors from the
main power supply to the panelboard Refer to
Figure 8 13 (a) and (b) for conductor 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
minimumlof 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
emerges1
8.6.4.4 Serviceequipment meter base Either an overhead or
underground entrance may 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,
connect1the neutral (white) conductor to the system
grounding (green) conductor on the supply side of
the main disconnect Refer to Figure 8 13 for
typical meter base installations and one method of
grounding the service equipment The homeowner must
provide the grounding electrode conductor(s) The
grounding electrode should be an 8 ' length of 1/2"
dia. 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 4rounding clamp For added protection, homes
with metal frames or siding should be connected to
earth by means Of additional bonding jumper ground
fault lturn paths to underground metallic water
pipes, round rings, additional ground rods, etc to
prevent the buildup of hazardous voltages
8 6 5 Crossover conneotions Refer to Figure 8 15 (a) , (b) , (c) ,
(d) , (e) , (f) and -(g) for typical crossover wiring
connections, for multisection homes (located along the
centerline between the sections) Crossover locations can be
distinguished bey metal junction boxes or access cover panels
Remove these p nels and connect the enclosed wires as
67
illustrated Some crossover connectors plug together and do
not require junction boxes
8 6. 6 System test procedures and equipment
8.6. 6 1 Pre-connection tests Conduct both of the following
tests before any electrical power is supplied to the
home
8.6 61 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 6 1 2 Grounding continuity. Using a continuity
tester, test all noncurrent-carrying metal
parts to assure continuity to ground The
Darts to be checked include
appliance enclosures, including fans;
fixture enclosures and canopies
metal siding and roofs;
• metal water supply and gas lines
metal ducts (except foil-covered
insulated ducts) ;
the home's frame
On multisection units, perform this test
only after completing all electrical and
bonding connections between the units
NOTE: GROUNDING I8 NOT REQUIRED ON THE
METAL INLET OF A PLASTIC WATER SYSTEM OR
ON PLUMBING FACTURES SUCH AS TUBS,
FAUCETS, SHOWER RISERS, AND METAL SINRB
WHEN THEY ARE CONNECTED ONLY TO PLASTIC
WATER AND DRAIN PIPING
8. 6 6.2 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
ACTIVATING THE WATER HEATER CIRCUIT FAILURE TO Do
BO WILL CAUSE THE WATER HEATER ELEMENT TO BURN OUT,
AN EVENT NOT COVERED BY THE WARRANTY

68
8. 6.6.2 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 end outlet configurations
Investigate any indication of reversed
polarity, open grounds or shorts and
correct it
8:6.6.2.2 Ground �Fault Circuit Interruption (aFCI) .
Make certain that all receptabies
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 the receptacle has been
u
interrpted, or follow the manufacturers
instructions Replace any GFCI that does
not operate properly
8 6 6.2..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 retesting

items
9 1 Water and drain systems All water and drain systems work
properly and do not leak
9 2 Appliance function and operation Appliances have been
tested and work properly
9 3 Windows, doors and drawers All windows, doors and drawers
work. properly
9 4 Exit windows One window in each bedroom is designated as
secondary exit to be used in case of emergency Each exit
window is labeled as such with operating instructions All
shipping hardware should be removed and the window should
operate as explained in the window manufacturer's
instructions (?dote Egress doors may be provided in place
of egress windows )
9 5 Exterior siding and trim There are no gaps, voids, or
missing fasteners, and all seams are sealed
9 6 Stack heads and vent pipe flashings on roof All stack head
or vent pipe flashings are properly attached and sealed
9 7 Composition roof. All shingles are properly attached, none
are loose or missing, all holes are filled and no fasteners
are exposed
9 8 Skirt and foundation venting The skirting around the home
has nonclosing vents, located at or near each corner as high
as possible to cross-ventilate the entire space under the
home The free area of these vents must be equal to at least
one square foot for every 150 square feet of floor area of
the home The vent size must be increased to allow for
insect screens, slats, louvers, etc , used over the open vent
area
9 9 Low-hanging trees and bushes If there are any low-hanging
trees or bushes near your home, trim or cut them Think
about the plants ' possible movement during windy conditions
or under snow or ice loads in limiting their future growth
9 10 Exhaust fan operation and air flow Check all exhaust fans
for proper operation and air flow
84
9 11 Bottomboard. Carefully inspect the bottom covering of the
home for loosening or tears from installation of pipes or
wires. Seal openings around the floor perimeter, pipes or
pipe hangers and splits or tears with weather-resistant tape
See bottomboard manufacturers patching and repair
instructions for proper methods (separately provided with
this manual)
9.12 Ground cover. Repair any cuts or tears in the ground cover
with tape
9 13 Anchors and straps. Be sure the correct number of anchors
have been installed at the proper angle, and that all straps
have been tightened
9 14 Interior detailsJ) Inspect for, and correct, all interior
finishing details, such as loose molding-, carpet seams, etc
The retailer" s representative should inspect the home with the
homeowner, give the homeowner a copy of the Homeowner's Manual, and
brief the homeowner about maintaining- the home
85
CHAPTER 10 - RELOCATING THE HOME
10.1 Relocation -of the home. If it is necessary to move your
home, HAVE IT ROVED BY A PROFESSIONAL MANUFACTURED HOME
MOVER, MAKE 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 damage will not be covered
under your warranty, and you may be held liable for any
failures Check with Karsten Homes, your home 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
10. 1. 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
10 1 6 Transit of furniture and belongings Substantial damage may
result if furniture, personal belongings, setup materials or
other items are stored in the home during transit TRANSIT
DAMAGE IS NOT COVERED UNDER YOUR WARRA "ry
10 1 7 Multisection homes Re-install temporary structural supports
and bracing materials before moving the home Cover open
sides of sections with weather-proof materials 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 at a
maximum of 4 ' on center
