FLOOR CROSSOVER
When making electrical connection(s) in the floor, use one of the wiring options de-
scribed below:
Method 1: Access panel i
1. Access wires. Find the crossover location(s) and remove the access panel(s)
if attached. If access panel openings are not provided, cut through bottom
board to expose the wiring (Figure 47). '
2. . Route wires. Pass the wires through predrilled holes or notches in the rim
joist or if there is a single bumped -out access panel as in Figure 48, then un-
der the rim joists. If holes or notches have not been provided and there is no
bumped -out access panel, drill maximum one -inch diameter hole(s) half -way
up the rim joists on each home section, making sure the holes align and feed
the wire through the hole.
3. Connect wires. Connect wires via a junction box or snap-connector(s) as de-
scribed above.
4. Secure wires. Secure wires with staples to adjacentjoists or studs within
eight inches of junction box or snap-connector(s).
5. Install smash plates. For notched perimeter joists, install steel wire protec-
tors (smash plates).
I
6. Seal bottom board. Replace insulation and re -install access panels and/or
seal the bottom board with tape specially made for that purpose (may be: pro-
vided). The access panel(s) may be temporarily installed near the crossover
location or shipped loose with the home. '

1. Access boxes. If junction boxes are not exposed, access them inside the
floor by cutting the bottom board or by removing the access panel(s). Remove
the junction box covers.
2. Connect wires. If wire is coiled inside one junction box, insert it into provided
flexible conduit and pass it under the rim joists to the opposing box and make
the connection as described above. If no coiled wire is provided, install pro-
vided ship -loose conduit with wire making connections in both boxes (Figure
49).
3. Cover boxes. Replace and secure covers on junction boxes.
4. Seal floor. Replace any displaced insulation and replace access panel or seal
the bottom board with tape specially made for that purpose (may be provided).
Variation to Method 2: Ajunction box may be installed only on one side with the
other side containing conduit behind an access panel. Bring the conduit to other
side and make one connection in the junction box.

3. Test. Conduct a two-part leakage test on the completed drainage system as
follows:
• Part 1. With all fixtures connected, and all tub and shower drains plugged,
fill the system with water to the rim of the toilet bowl through a higher fix-
ture. Release all trapped air, replace tub and shower plugs, backfill fix-
tures, and allow the system to stand at least 15 minutes. Check for leaks.
Drain the system. If leaks are found, repair and retest.
• Part 2. Plug all fixtures, sinks, showers, and tubs and fill with water. Re-
lease the water in all fixtures simultaneously to obtain the maximum pos-
sible drain piping flow. As water is draining, check for leaks. If any are
found, repair and retest.

6. Insulate. Replace all insulation and make sure all potentially exposed portions
of the DWV system are well insulated to protect against freezing.
STEP 6. CONNECT GAS LINES
The gas crossover connection may use quick disconnect fittings or threaded connec
tors. Find the connection location below the Floor at the marriage line and gather the
connectors (they may be shipped loose if not present under the home).
For quick disconnect fittings (Figure 59), remove any dust caps and then with one
hand, pull back on the quick disconnect device, snap it over the quick disconnect adap-
tor and release it to complete the connection.
For threaded connectors (Figure 60), remove the black cap and nipple (or any other
plugs, such as a black iron plug) from both the supply and receiving sides and screw
the connector onto the supply and return pipes as necessary.
Check for leaks before connecting to gas service (see Connect Utilities, STEP 3.
CONNECT GAS SERVICE, p. 81).

1. Install panels. Install ship loose gypsum panels using a 1/4 inch diameter
bead of adhesive on all framing members and minimum 1-1/2 inch long dry-
wall screws, nails, or staples at six inches o.c. along panel edges and 12
inches o.c. in the field into framing members.
2. Mud seams. Mud and tape all seams and comers, filling all fastener depres-
sions. Follow mud manufacturer's directions.
3. Paint. When the final coat of mud is dry, prime and paint all unfinished gyp-
sum board to match existing paint color and finish texture.
STEP 3. COMPLETE WALL AND CEILING FINISHES

Install Stabilizing Systems
This chapter covers the design and installation of the stabilizing system which secures the home against lateral and up-
ward forces caused by wind. The system covered here uses earth (or ground) anchors and steel straps connected to the
home's longitudinal steel beams and/or exterior walls. Stabilizer plates may also be used to prevent the anchor head from
moving laterally in the ground. An anchor, strap, and stabilizer plate (if used) together are referred to as a tie -down.
Anchors can also be mounted in concrete footings when there is enough concrete mass (weight) to resist the lateral and
upward forces. This type of system is not covered in this manual.

STEP 4. INSTALL ANCHORS (p. 70)
STEP 5. INSTALL STRAPS (p. 71)
STEP 6. TIGHTEN AND ADJUST STRAPS (p. 74)
STEP 1. DETERMINE ANCHOR LOCATIONS
Create a sketch of the home plan showing the exterior walls, marriage line(s) (if any)
and frame 1-beams (this will be similar to the base sketch created in Prepare Footings,
page 17).
See Table 21 for a list of anchor locations, types, and where they are required. Pages
where the requirements are provided are noted in the last column.
As each anchor location is determined, mark it on the sketch, noting important dimen-
sions such as spacing between anchors. When complete, this will be the home's tie -
down plan (Figure 61 and Figure 62).

Use Table 22, Table 23 and Table 24 to determine the spacing between anchors for
Wind Zones I, II, and III, respectively. Spacing requirements will vary depending on the
type of home (single or multi -section), the slope of the roof, the width of the floor, for
each section, the sidewall height, I-beam spacing, and the height from the ground to
the strap attachment point. Determine the values for the home. Using the table for the
appropriate wind zone, determine the column and row that corresponds to the charac-
teristics of the home. The value on the tables is the maximum distance between -an-
chors. Keep in mind that sidewall frame tie -downs must be located no more than two
feet from each end wall.
Notes to Tables:
1. Designs based on max 99 Y:" I -Beam spacing.
2. Tables apply to both Multi section and Tag units and are for Exposure "C" sites.
3. When using the FAR beam method and utilities prevent strap from being properly installed
to the top of the Main I-beam, the strap may alternatively depart from the bottom of the beam,
but must be within 3" of a crossmember or approved I-beam brace.

SIDEWALL VERTICAL ANCHORS j
Homes designed for Wind Zones II and III also require vertical tie -downs along the ,
sidewalls. The vertical tie -down anchor straps (or brackets for connecting to the home)
are factory installed and indicate the locations. Vertical and frame sidewall tie -downs 0
may connect to one double -headed anchor or each to its own dedicated anchor.
Any factory -installed sidewall tie -down straps must be connected to a ground anchor
regardless of the wind zone in which the home is placed.
END WALL FRAME ANCHORS
End wall frame tie -downs are especially important for homes that are wider and have
higher roof pitches because those features increase the surface area exposed to wind 4 * L
loads at the ends of the home. Use Table 25 to determine the number of end wall a. J
frame anchors required at the each end of each home section. Palm Harbor Homes
recommends the use of Longitudinal Stabilizing Devices (LSD) or other ap-
proved systems. These devices or systems are NOT provided by Palm Harbor i �I�ROfi` �i dAt�
Homes. Companies, such as Tie -Down Engineering, Inc., and other manufactur-
sp
ers, may be contacted to obtain such devices. Table 25 is based on Tie -Down ; l �•. �. ';

STEP 2. DETERMINE TIE -DOWN CONFIGURATION
There are two primary tie -down configurations: the near beam and the far beam meth-
ods. (Figure 63).
Near beam method. For all Wind Zones, connect an anchor strap from the
anchor head to the beam closest to the anchor. See Figure 67. In -line anchor
configuration and Figure 68. Stabilizer plate configuration .For Wind Zones II
and III connect a vertical strap from the sidewall factory installed tie of the
home to the anchor head using a double -headed anchor; connect the other
strap to the beam closest to the anchor. Refer to Table 22 for maximum
heights from ground.
Far beam method. For Wind Zones II and III connect one anchor strap) from
the anchor head (using a double -headed anchor) to the home's near beam or
far beam and one to the sidewall of the home. Refer to Table 23 andTable 24
for maximum heights from ground.
STEP 3. SELECT ANCHORS
Use the torque probe results from Prepare the Site, STEP 5. DETERMINE SOIL -
BEARING CAPACITY AND FROST LINE (p. 14) and the anchor manufacturer instruc-
tions; select the type and length of anchor to use. The installed ground anchor size
(length) must be listed (i.e. approved) for the soil class.
Make sure the anchor is of sufficient length such that the top of the helix is below the
frost line. Select a shaft diameter sufficient to resist excessive torsion, "ring -off' (when
the helix or anchor head separates from shaft) or shaft splitting. Consult the anchor
supplier for guidance.
Review all of STEP 3. INSTALL ANCHORS (p. 69) and STEP 4. INSTALL STRAPS
(p. 70) before making final anchor selections to determine when single -headed vs.
double -headed anchors should be used. Follow the specifications in Table 30 when se-
lecting stabilizing system components.

Figure 66. Lateral tie -down con -

Anchors must be tested and listed to resist aminimum ultimate load of 4,725 Ibs and a minimum allowable
working load of 3,1501bs or ultimate and corresponding working load limited by soil conditions and anchor
length. The working load is the maximum load the designer can use. Ground anchors must be provided
with protection against weather deterioration and corrosion ehleast equivalent. to that provided by acoating
of zinc on steel of not less than 0.30 oz per sq ft of surface coated.
Straps must be minimum 1-1/4" x 0.035" zinc -coaled (0.30 oz per sq ft) steel strapping conforming to
ASTM D3953-97, Type 1, Grade 1, Finish B with a minimum allowable working load capacity of 3,150 Ibs
and a minimum ultimate load of 4,725 Ibs. Slit or cut edges of zinc -coated strapping do not need to be zinc
coated.
The size and type. of stabilizer plate, if required by the ground anchor manu acturer, will be specified in the
anchor manufacturer's instructions. Stabilizer plates mustbe provided with protection against weather
deterioration and corrosion at least equivalent to that provided by a coating df zinc on steel of not lass than
0.30 oz per sq ft of surface coated. Alternatively, ABS stabilizer plates may e. used when listed and certi-
fied for such use. �;.

STEP 4. INSTALL ANCHORS
Before beginning anchor installation, check for obstructions under the home such as
piers and frame members that may interfere with the tie down strapping. Check with
utility companies to determine the location of underground utilities, such as electrical
and phone lines, and water, sewer, and gas pipes that may be buried in potential an-
chor locations. Also check for homeowner -installed wires and pipes, such as those
connecting exterior lighting or sheds to the home. These must also be avoided.
FRAME ANCHORS
Frame anchors can be installed in two ways, in -line and against a stabilizer plate. The
two methods are discussed below:
In -Line Configuration
The in -line configuration (Figure 67) for homes can be used in Wind Zone I only. Typi-
cally, in -line anchors are used under high homes where the anchors can be installed
from under the home after the home is set. In -line anchors can also be installed before
the home is set, however, precisely aligning the anchor with the home both vertically
and horizontally is difficult. Using swivel connectors for the strap to beam connection
can provide some horizontal flexibility.
To install in -line frame anchors, drive the anchor into the ground at an angle and loca-
tion such that a straight line can be drawn from the tip of the anchor through the anchor
head and to the connection point on the I-beam (Figure 68).

StabSaerNta
Stabilizer Plate Configuration
Stabilizer plate configurations (Figure 68) are suitable for homes in all wind zones. An-
chors may be installed after the home is set. A stabilizer device, typically an ABS or
metal plate, is used to prevent the top of the anchor from slicing through the soil when
the load is applied. Stabilizer plates are available in a variety of widths. Choose the
widest plate that can be driven into the soil to maximize resistance to movement. The
LAHJ may have stabilizer plate requirements.
Install anchors with stabilizer plates as follows:
1. Locate anchor. Select a location for the anchor under the home but within
six inches of the exterior wall (Figure 69). Avoid locations that will interfere
with skirting.
10/20/08
@Grading area
around anchors. Anchor
heads should not rest in
sunken spots. Grade the
ground so that water does
not collect around anchor
heads, but runs away from
the anchor and out from
under the home. Do not
bury anchor heads.

configuration

HUD niHCSS
10/20/08
2. Install anchor. To assure that the anchor attachment point will end up at the
stabilizer plate, start the anchor insertion approximately 12 inches back from
from the desired location if using a 48 inch long anchor, or approximately 16
inches if using a 60 inch long anchor. Install the anchor at about 15 degrees
off vertical, with the head tilted away from the home. Install the anchor to a
depth of approximately -one half its length.
3. Drive stabilizer plate. Drive the stabilizer plate into the ground to its full depth
at the point determined in Step 1.
4. Complete anchor installation. Screw the anchor the rest of the way into the
ground. The finished anchor must be installed to its full depth.
VERTICAL ANCHORS
To install vertical anchors, screw the anchor into the ground directly under the strap at-
tachment point on the home until the bottom of the anchor head is flush with the ground
or no more than one inch above grade.
STEP 5. INSTALL STRAPS
Follow the instructions below to connect straps from the home to sidewall frame, end
wall frame and vertical anchors.
Always protect straps at sharp corners including around I -beams with radius clips or
other methods (Figure 70). Radius clips may be fabricated from 26ga (min) by 1 '/<-
inch wide galvanized steel strap formed to fit around corners.
1 Longitudal
Bracket
SPLICING STRAPS
Splicing may be required when a pre-cut strap is of insufficient length. Splices in tie -
down straps are not permitted in a configuration. Overlap straps by 12 inches, ap-
plying one splice clip from above and the other from below•, use a crimping tool to
tightly seal the splice clips (Figure 71). Do not run any portion of the splice through an
anchor head bolt.

(approximately 2 1/2 inches per turn or 71/2 to 13 inches total). Fewer than
three turns and the strap may not hold onto the bolt when force is applied.
Conversely, more than five turns may not fit within the U-channel of the an-
chor head. Follow the procedure outlined in Figure 73.

3. Pretension anchor. For anchors with stabilizer plates, pretension the anchor
by pulling it up to the stabilizer plate using the strap and take-up bolt to move
the anchor head. Continue pulling the strap until the plate moves a small
amount (about 112 inch). This is called packing the plate and it will yield the
strongest resistance (the bottom of the anchor head should be maximurri 1/4
inch above the top of the stabilizer plate).
END WALL FRAME ANCHORS
Attach straps to the bracket welded by the manufacturer to the frame (Figure 74). If no
brackets have been installed, use approved beam clamps designed specifically for this
purpose, available from anchor suppliers. Connect straps to anchors following same
procedure as for sidewall frame anchors.

STEP 1. CONNECT ELECTRICAL SERVICE
The home is designed for connection to an electrical wiring system rated at 120/240
volt AC. All electrical field work must be done by a licensed electrician or other person
approved by the LAHJ.
FEEDER WIRE AND EQUIPMENT SIZES i
The current rating (in amperes) of the home can be found on the tag located on the
outside next to the feeder or service entrance, and on the electrical distribution panel.
Using this information, determine the required feeder wire size from Table 34. These

FEEDER CONNECTIONS
Feeder connections are made from above or from below the home as follows:
From above — mast weatherhead feeder
The routing, connection, and support of the service drop must meet local codes.
Homes equipped this way contain all necessary conduits to the electrical distribution
panel. However, the feeder conductors (not provided with the home) are installed on
site. If the masthead is located above the roof overhang, allow a minimum clearance of
eight feet above all roof points that the conductors pass over. There are two exceptions
to this rule: (1) The vertical clearance may be reduced to three feet if the roof has a
minimum slope of 4 in 12: and (2) The vertical clearance may be reduced to 18 inches
if no more than four feet of service -drop conductors pass above the roof overhang, and
if they terminate at a through -the -roof raceway or approved support. A minimum clear-
ance must also be provided from the final grade to the service -drop conductors. This
measurement may vary from 10 feet to 18 feet, depending on the types of traffic antici-
pated below the service drop (refer to the NEC). 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.
From below — underside junction box feeder
A section of conduit is factory installed through the Floor cavity. Connect to that conduit
with approved fittings and conduit (not provided with the home) to the point where the
service entrance cable enters the crawl space. Install properly -sized service entrance
conductors from the main power supply to the panel board. Depending on the location
of the main panelboard inside the home, or the point at which the service entrance
conductors enter the crawl space„a separate service disconnect may be required. Re-
fer to Table 34 for the conductor and junction box requirements. The installer must
provide the supply connection including the feeder conductors, junction box, and con-
duit connectors. Protect conductors emerging from the ground from a minimum of 18
inches below grade to eight feet 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 the minimum burial requirements outlined in the NEC.
Use a moisture -proof bushing at the end of the conduit from which the buried cable
emerges.
GROUNDING
The home must be properly grounded to protect the occupants. The only safe and ap-
proved method of grounding the home is through an electrically -isolated grounding bar
in the manufactured home distribution panel board. This grounds all non -current -
carrying metal parts to the electrical system in the home at a single point.
Each neutral conductor must be connected to the system grounding conductor on the
the supply side of the main disconnect in accordance with Articles 250.24, 250.26, and
250.28 of the National Electrical Code, NFPA No. 70-2005.
Where the meter base has a disconnect (typically when the meter is more than 6 feet
from the service electric panel, although this may vary by LAHJ) the ground and neutral
should be bonded at that disconnect and then grounded to the driven earth
ground. Four wires will leave the service electric panel to the disconnect. Three wires
will enter the disconnect from the meter base (refer to Figure 75).
Where there is no disconnect on the meter base or between the meter base and ser-
vice electric panel (typically when the meter is within 6 feet from the service electric
panel, although this may vary by I.AHJ), the main circuit breaker in the service electric
panel becomes the first disconnect. In this case, the neutral and ground are bonded in
the service electric panel and connected to the driven earth ground from the service
electric panel. Three wires lead between the meter base and the service electric panel
(refer to Figure 76).
! / A
Power supply. A large
enough power supply must
be available at the site. An
inadequate power supply
may result in improper op-
eration of and possible
damage to motors and ap-
pliances. It may also in-
crease electricity costs.
Grounding the electrical
system. Do not provide
electrical power until the
grounding electrode is in-
stalled and connected.
When the meter base is not
on the house never use the
neutral conductor of the
feeder cable as a ground
wire.

In all cases, a grounding electrode conductor and a ground wire must be installed ac-
cording to the following specifications:
1. Grounding wire to be per Table 34 provided by the manufacturer. If manufac-
turer provides a minimum 1/2 inch EMT or conduit raceway, the #6 minimum
bare copper wire is provided by the retailer for installation.
2. The clamp connecting the grounding wire to the electrode shall be suitable for
direct burial and located flush or below ground level.
3. Use a listed 518 inch diameter by eight foot long iron electrode or nonferrous
rod of at least 1/2 inch diameter by eight feet long for grounding (larger sizes
may be required by the LAHJ due to soil impedance).
4. Drive the electrode to a depth of not less than eight feet so that at least eight
feet of the electrode is in contact with the soil.
5. When rock is encountered, the electrode may be driven at an angle not'to ex-
ceed 45 degrees from vertical or buried in a trench that is at least 2-1/2 feet
deep.

• The grounding bar may be installed separate from the neutral bar for pur-
poses of testing the electrical system.
• The grounding bar may be isolated during the electrical check and re-
attached, after the tests are completed.
• Check with the local electrical utility to verify meter base requirements and lo-
cations and distances for the main panel and meter box.
• The field installed meter base enclosure must be installed in accordance with
its listing. Fasten securely to exterior wall studs and provide for a weather -
tight seal.

STEP 2. CONNECT WATER SERVICE
CONNECTION
To connect the home's water system to the water source, identify the water inlet lo-
cated under the home (usually below the water heater compartment or utility room) and
follow the procedure described below (refer to Figure 78):
1. Flush pipe. Flush field -installed water piping free of all debris prior to connec-
tion to the home's water inlet.
2. Clean threads. Ensure that pipe threads are clean.
3. Install pressure -reducing valve. If the local water supply exceeds 80 psi in-
stall a pressure -reducing valve.
4. Connect valve. Install a main shut-off valve between the water supply and
the inlet on the home. Locate the riser for the shutoff valve underneath or ad-
jacent to the home. Select a full Flow gate or ball shutoff valve, or equivalent
valve. To prevent the possibility of fresh water contamination install an anti -
siphon valve on all field installed exterior faucets.

5. Install water heater discharge drain. Inspect the drain opening on the water
heater to ensure that it is clear of any obstruction. If the home is to be installed
on a basement or enclosed crawlspace, install drain pipe connecting the dis-
charge from the water heater temperature and pressure relief valve to the out-
side or to a sump.
6. Install water heater drip pan drain. Assure that the drain for the water
heater drip pan does not terminate under the home. Using the materials pro-
vided and the accompanying instructions run a drain line from the water
heater drip pan through the wall or floor to the exterior of the crawl space.
Terminate the line between six and 24 inches above grade. (Figure 79). Make
the termination point rodent proof.

7. Insulate. In areas subject to freezing temperatures, protect with insulation or
heat tape pipes, valves and pressure reducers that are exposed to the out-
doors; and pipes in water heater compartments with non -insulated doors.
Connect heat tape to the electrical outlet under the home near the water sup-
ply inlet.
TESTING
After testing the electrical system and connecting the water lines check the water sys-
tem for leaks using one of the procedures described below. Before testing, close all
water faucets, spigots, and toilet -tank float valves.
Hydrostatic (preferred):
1. Bypass water heater. Bypass the hot water heater by disconnecting the hot
outlet and cold inlet water lines from the water heater and joining them to-
gether. This will protect the hot water tank from damage and protect those in-
volved in the test from possible injury.
2. Fill water heater. Confirm that the water heater tank is full of water.
3. Pressurize system. Connect a hydrostatic pump, valve, and gauge to the lo-
cation shown in Figure 78. Pressurize the system with water at 100 psi, and
then isolate it from the pressure source. Bleed all air from the highest and far-
thest points in the system.
4. Hold pressure. Monitor the pressure for at least 15 minutes.
5. Fix leaks. If the pressure drops below 100 psi, locate and correct any leaks
by cutting out and discarding bad pipe sections or joints and installing new
pipe orjoints with couplings.
6. Repeat. Repeat the test until all leaks have been eliminated.
Pneumatic:
1. Bypass water heater. Bypass the hot water heater by disconnecting the hot
outlet and cold inlet water lines from the water heater and joining them to-
gether. This will protect the hot water tank from damage and protect those in-
volved in the test from possible injury.
2. Pressurize system. Connect an air pump and pressure gauge to the water
inlet, pressurize the system to 100 psi and isolate the pressure source from
the system.
3. Hold pressure. Monitor the pressure for least 15 minutes. If the pressure
drops below 100 psi, locate any leaks by applying soapy water to the connec-
tions and looking for bubbles.
4. Fix leaks. Correct any leaks by cutting out and discarding bad pipe sections
or joints and installing new pipe or joints with couplings.
5. Retest. Repeat the procedure until all leaks have been eliminated.
6. Restore connections. Reconnect the water heater and the water supply.
FREEZE PROTECTION FOR UNOCCUPIED HOMES
If the home is to be left unheated in cold weather, protect water lines from freezing as
follows:
1. Disconnect supply. Turn off the water supply and disconnect the water sup-
ply inlet.
2. Drain water heater. Turn off the water heater; if necessary, attach a hose to
the valve to direct water away from under the home, open the drain valve and
drain the tank completely.
3. Drain faucets. Open all faucets throughout the home (including the laundry
area if plumbed, and any exterior faucets) and let them drain completely.
4. Drain toilets. Flush toilets and drain water tanks completely.
5. Close faucets. Close all water faucets with the exception of one.
6. Connect compressor. Connect a maximum of 30 psi air supply to the water
inlet connection using a low pressure compressor.
7. Open faucets. With the air supply on the system, open one faucet at a time
throughout the home.

' //
Selecting heat tape. Use
only pipe -heating cable
(tape) listed for manufac-
tured homes, and install it
in accordance with the ca-
ble (tape) manufacturer in-
stallation instructions.
Testing water lines. Only
use pneumatic (air) testing
when hydrostatic testing is
not practical. Air under
pressure is explosive. Ex-
ercise extreme caution and
notify all site personnel of
the test. Wear protective
eyewear and take precau-
tions to prevent impact
damage to the system
while the test is in progress.
Do not pneumatically test
CPVC systems. Pneumati-
cally test Flow Guard Gold
systems only at low pres-
sure levels (20 psi or less).
Pressurizing water lines.
When pressurizing the wa-
ter system, connect the
pump to a location above a
closed shut-off valve so as
not to introduce pressure
into the municipal water
supply.
n
10/20/08
8. Disconnect compressor. After the entire system has been drained of all wa-
ter, disconnect the air supply and close the water inlet valve.
9. Pour anti -freeze. Pour an antifreeze solution into all drain traps, including
sinks, tubs, and toilets. Be sure that the antifreeze is safe for the fixtures and
P-traps.
STEP 3. CONNECT GAS SERVICE
CONNECTION
If the home uses natural or liquid petroleum gas (LPG, also known as propane) for'wa-
ter or space heating, cooking or other appliances, follow the procedure described be-
low:
1. Inspect vents. Assure that all exhaust vents on gas -fired equipment are se-
curely connected and that roof jacks and stacks have not come loose during
transit and they are properly installed.
2. Review appliance instructions. Review each appliance manufacturers in-
structions before the home is connected to the gas supply. Most gas appli-
ances are typically configured to operate on natural gas. If the gas supply will
be LPG, consult the appliance manufacturer's instructions to determine what
changes need to be made. For homes located above 3,000 feet, appliances
may require a different orifice.
3. Remove cap. Remove the protective cap from home inlet pipe and install a
full flow shut-off valve at the supply inlet (Figure 80).
4. Install regulator. The gas piping system is designed for a pressure that is at
least seven inches of water column (4 oz. per sq in or 0.25 psi) but not more
than 14 inches of water column (8 oz. per sq in or 0.5 psi). If gas from any
supply source exceeds, or could exceed this pressure, install a regulator if re-
quired by the LAHJ.
5. Connect supply. Using matching threaded fittings, connect the gas supply to
the inlet side of the shut-off valve.
6. Close valves. Close all valves at appliances prior to opening the main supply
valve. I

TESTING
Test the gas piping system in the following two ways: 1) piping only and 2) entire'sys-
tem. Consult with the LAHJ for any additional testing or start-up requirements.
Before testing is begun, the temperature of the ambient air and the piping should Ibe
approximately the same. Conduct the tests when and where air temperatures will re-
main constant.

3. Pressurize system. Using an air compressor, pressurize the system with
compressed air to three psi and isolate the pressure source from the system.
4. Monitor pressure. Monitor the pressure for at least 10 minutes.
5. Check for leaks. If pressure drops below three psi, check for leaks by apply-
ing a non -corrosive, ammonia -free gas leak detection fluid to the joints at all
valves, appliance connections, and crossover connections (do not use dish
washing detergents, soap, or other household chemicals). If bubbles form,
tighten the connection and recheck.
6. Repair leaks. If leaks persist, replace defective pipes or fittings with sound
material and retest.
7. Release pressure. Release pressure and open all appliance shut-off valves.
8. Rinse connections. Thoroughly rinse all tested connections with water to
remove leak detection fluid.
Entire system test (with appliances)
1. Close appliances. Close all gas equipment controls and pilot light valves ac-
cording to the individual gas equipment manufacturer's instructions.
2. Open valves. Assure that gas shut-off valves for all gas equipment are in the
open position.
3. Attach gauge. Attach to the home's gas inlet a pressure gauge calibrated in
ounces.
4. Pressurize system. Pressurize the system with compressed air to six to eight
ounces (3/8 to 112 psi, or 10 to 14 inches of water column).
5. Check for leaks. Check for leaks as described above in step 4 of the Piping
only test. Replace defective pipes or fittings with sound material and re -test.
6. Rinse connections. Thoroughly rinse all tested connections with water to
remove leak detection fluid.
GAS APPLIANCE START-UP
Open the shut-off valve for each appliance and adjust the burners according to the ap-
pliance manufacturers instructions. Verify that the furnace and water heater thermo-
stats are operating properly and set them to the desired temperatures.
STEP 4. CONNECT OIL SERVICE
Homes that are equipped with oil burning furnaces must have oil supply piping installed
and tested on site by a qualified professional in accordance with NFPA 31, Standard
for the Installation of Oil Burning Equipment, 2001 or the requirements of the LAHJ,
whichever is more stringent. The home manufacturer does not supply oil piping or
tanks.
OIL CONNECTION
Consult the furnace manufacturer's instructions for proper pipe -sizing and installation
procedures. Where piping is run through the bottom of the home, ensure all holes in
the bottom board are sealed tight with foam, mastic, and/or tape specially made for that
purpose and made rodent proof.
When equipping the home with an oil storage tank, comply with the following:
• Install the pipe with a gradual slope toward the fill end or drain plug (if so
equipped) to facilitate pumping or draining of water and sludge.
• Provide a readily accessible approved manual shut-off valve at the outlet, in-
stalled to close against the supply.
• Equip the tank with an approved oil filter or strainer located downstream from
the tank shut-off valve. Use a filter or strainer containing a sump with a drain
to trap water.
• Equip under ground tanks with a filler neck extending one foot above grade
and a minimum 1-1/4 inch diameter vent pipe extending at least two feet
above grade.
• Locate the tank to be accessible for service and inspection, and safe from fire

• If the tank is located inside a compartment of the home, provide ventilation at
the bottom of the compartment to permit diffusion of vapors. If the tank is
fixed to the home, provide for filling and draining from the outside.
• Insulate interior tanks from the structural members of the home. Provide tanks
so installed with an outside fill and vent pipe and an approved liquid level
gauge.
Install tanks that feed vaporizing type oil furnaces so that oil flows by gravity.
To achieve efficient gravity flow, make sure that the bottom of the tank is; at
least 18 inches above the furnace oil control level.
Tanks for gun type oil furnaces (these furnaces include a fuel pump) may be
installed above or below ground.
OIL SYSTEM TESTING
Before operating the system, fill the tank to capacity with the fuel to be burned and
visually check all joints in the system for leakage. Replace (do not repair) parts that
leak.

PREPARE HEATING SYSTEM
If the home does not contain a factory installed heating appliance, install a remote
heating appliance according to INSTALL REMOTE HEATING AND COOLING
EQUIPMENT, p. 85. Prepare fuel-buming heating systems included with the home as
follows:
1. Inspect for damage. Inspect the furnace and report any damage to theihome
manufacturer.
2. High altitude. If the home is located more than 2,000 feet above sea level or
as indicated in the furnace manufacturer's instructions, derate gas furnaces
4% for each 1,000 feet above sea level. This work must be done by a qualified
(and in some jurisdictions, licensed) technician.
3. Convert for LPG gas. If LPG gas (propane) will be used, convert the appli-
ance from natural gas to LPG gas use. Conversion must be made by a quali-
fied and (if required by the LAHJ) licensed technician.
4. Install intake air pipe. Consult the appliance manufacturer's instructions for
maximum allowable pipe run length, requirements for air dampers, locations
relative to expected snow levels (check with the LAHJ for expected snow lev-
els), acceptable materials, pipe supports, and pipe termination requirements.
5. Install flue. For combustion appliances, install the flue roof cap and stack as-
sembly as described in PREPARE FIREPLACES, Chimneys (p. 88).
INSTALL REMOTE HEATING AND COOLING EQUIPMENT
Install remote units in compliance with all heating and cooling equipment requirements
in this chapter above and the following:
1. Locate connections to the home. Find the manufacturer -installed connec-
tors, labels, or tags under the home indicating the required connection points
for supply and return air. If connectors are not provided nor location indicated,
select a supply duct location such that there are approximately equal numbers
of supply registers forward and rear of the connection point. Locate the return
duct in the center of the home.
2. Install ducts. Install the appropriate supply and return ducts (not provided)
between the remote unit and the home (Figure 83), making connections ac-
cording to the instructions for crossover ducts in Crossover Connections (p.
48).
3. Install dampers. If installing a remote cooling unit in a home with a factory in-

PREPARE VENTILATION SYSTEM
Prepare the whole -house ventilation system according to the ventilation system manu-
facturer's instructions. Confirm that any fresh air intake ducts extend to the exterior and
do not draw air from the crawlspace under the home. Do not allow any fresh air ventila-
tion intake ducts to become kinked or restricted, forming a trap (Figure 83).
PREPARE FUEL -BURNING WATER HEATER
The water heater discharge and drip pan drains should have been installed in Connect
Utilities (p. 75).
In homes with direct -vent water heaters (that utilize gas, oil, or other combustion fuel),
and where the water heater is not independently vented to the exterior through a grilled
opening, provide combustion air from under the floor using pipe and cement acceptable
to the appliance manufacturer or through the roof via a double -walled flue pipe. If pro-
vided through the floor, run the air piping to the exterior of the home, with supports
spaced every 3-1/2 feet o.c. or less. Terminate the pipe facing downward a minimum of

PREPARE CLOTHES DRYER
DRYER VENTS
If the home includes a clothes dryer, the components for ventilating the dryer are in-
cluded with the home (but not necessarily installed) and a vent opening has been
roughed in either in the wall or floor. (If a dryer is not installed, seal all dryer vent open-
ings).
Run the dryer vent to the outside through the exterior wall or through the floor to a point
beyond the perimeter of the home, using materials approved by the clothes dryer
manufacturer (see Figure 84).

Install the vent as follows:
1. Remove temporary caps. Remove any temporary seals and duct caps from
the vent rough openings.
2. Install ductwork. Install ductwork using clamps (do not use screws or other
fasteners that penetrate into the duct) and support the duct with metal straps
connected to the floor joists or chassis at two feet o.c. or less. Ensure duct
connections are internally overlapped to prevent inhibiting the flow of air and
thereby causing lint accumulation.
3. Install cap and damper. Install an approved dryer vent cap with damper on
the exterior termination of the duct. If the vent terminates at skirting, secure
the cap to framing or skirting with sheet metal screws and seal edges with
caulk or sealant. If the vent terminates through a wall, apply a bead of sealant
to the back of the cap around the opening and secure with sheet metal screws
to metal, hardboard or fiber cement siding or with wood screws to a mouht
block for vinyl siding.
4. Seal opening. Seal openings inside and outside of the home including at the
floor, interior walls, siding and skirting (with caulk), and at the bottom board
using foam, mastic and/or tape specially made for that purpose.
GAS DRYERS
If the home was not fitted for a gas dryer, installing one requires substantial alteration
to the home. Gas supply piping and adequate venting must be provided as specified by
the dryer manufacturer and installed by a trained professional. Do not cut major struc-
tural elements to accommodate a gas dryer.
PREPARE SMOKE ALARMS
The home has several factory installed smoke alarms that are wired to a 120-volt,cir-
cuit. If the home was designed for placement on a basement, an additional alarmis
provided for installation at a pre -wired location under the home. Connect the basement

the smoke alarm circuit is on.
2. Remove batteries. Make sure backup batteries (if any) are removed from all
smoke alarms.
3. Test alarms. Press the test button on each alarm sequentially. All alarms
should sound simultaneously when the test button on any one smoke alarm is
pressed. Replace (with the same brand as those installed elsewhere in the
home) any alarms that do not sound and retest.
4. Replace batteries. After successful test, replace the backup batteries, dis-
carding the protective tabs.
PREPARE FIREPLACES
Install chimneys, chimney flashing and roofing, fireplace combustion air inlets, and
hearths according to the manufacturer's instructions and the procedures described be-
low.
CHIMNEYS
Fireplace and wood stoves may require on -site installation of additional sections of ap-
proved chimney pipe, a spark arrestor, and a rain cap assembly. Follow the manufac-
turer's instructions and the procedures described below:
1. Remove coverings. Remove protective materials covering the roof flashing
and any foreign material from the installed part of the chimney.
2. Install chimney pipe. Assemble and seal the chimney per the fireplace or
wood stove manufacturer's installation instructions and if there is a conflict be-
tween the instructions and the figure, follow the instructions. To assure suffi-
cient draft for proper operation, extend the chimney at least three feet above
the highest point where it penetrates the roof and at least two feet higher than
any surface within 10 feet of the chimney (Figure 86). Use additional sec-
tion(s) of chimney pipe (not provided) if required by local code or if the site
has obstructions within 10 feet of the chimney.

COMBUSTION AIR INLETS
Combustion air inlets provide combustion air through the floor or an exterior wall to a
combustion appliance. If through an exterior wall, site installation is not required. If
through the floor, extend the duct from its point just below the floor to the outside (addi-
tional duct material required for this may or may not be provided with the home). Lo-
cate the inlet damper above expected snow levels (contact the LAHJ for snow levels).
Follow the fireplace manufacturer's instructions (typically in the fireplace/stove or with
the chimney parts).
HEARTHS
If shipped loose, install the fireplace hearth according to the fireplace manufacturer's
instructions.
PREPARE KITCHEN AND BATH APPLIANCES / FIXTURES

STEP 3. INSTALL SKIRTING
Skirting is any structural or non-structural perimeter crawlspace enclosure. Complete
site -built structures (see STEP 5. COMPLETE SITE -BUILT STRUCTURES, p.96) that
abut the home (such as porches, attached garages, and steps) prior to installing skirt-
ing.
SPECIFICATIONS
Skirting must be of weather -resistant materials or provided with protection
against weather deterioration at least equivalent to that provided by a coat-
ing of zinc on steel of not less than 0.30 oz per sq ft of surface coated.
Skirting made from wood or wood products and used within six inches of
the ground needs to be made of materials naturally resistant to decay and
termite infestation or pressure treated. IIIIIpp���
Ventilation openings must be covered for their full height and width wit
perforated (1/4 inch maximum opening in any dimension) corrosion an
weather -resistant covering that is designed to prevent the entry of rode ts.
In areas subject to freezing, the coverings for to ventilation openings r�usl
have an operable damper, permitting them to be in the open or closed pc�si
tion depending on the weather.
To design and install skirting, comply with the skirting manufacturer's instructions (if
provided) and the following:
1. Configure skirting. Run the skirting along the perimeter of the home's
heated, conditioned space. Do not enclose with skirting areas under recessed
entries, porches, or decks (whether constructed as part of the home or added
on site) unless skirting is of the fully vented type and installed so as to allow
water to freely flow out from under the home.
2. Fasten skirting. Recess the skirting under the siding or trim and attach it -to
the home in a manner that prevents water from being trapped between the
siding or trim and the skirting. For wood, aluminum, or fiberglass skirting, in-
stall a skirt rail (lumber strip) under the floor inset at least 1-1/2 inches from
the edge of the siding for attachment of the skirting. Allow for frost heave
when installing skirting in areas subject to frost.
3. Provide ventilation. Unless the skirting has integral ventilation openings,that
meet the following ventilation requirements, install equally sized ventilation
openings on at least two opposite sides of the foundation. Size ventilation
area to equal at least one square foot or each 150 square feet of under -floor
area (or for each 1,500 square feet if a ground moisture retarder is installed
according to STEP 2. INSTALL GROUND MOISTURE RETARDER, p. 94).
Place vents as high above the ground as practical.
4. Install access. Provide an access opening not less than 18 inches wide and
24 inches high and located so that any utility connections located under the
home are accessible.
5. Extend vents, drains, and inlets. Run appliance exhaust vents, combustion
air inlets, and air conditioner condensation drains through the skirting to the
outside and terminate each as instructed in the sections of this manual corre-
sponding to each appliance.
STEP 4. ASSEMBLE OPTIONAL WIND PROTECTION SHUT-
TERS
If desired, prepare temporary protective window covers for use during severe wind
storms and hurricanes according to Figure 91, Table 36, and the procedure below.
1. Assemble extension framing using with two 16d common nails at each con-
nection.
2. Assemble shutter panels as shown in Figure 91.
3. Store the shutters such that they are protected from the weather, are not in di-
rect contact with the ground, and are easily accessible by the homeowner.
