Install Stabilizing Systems
This chapter covers the design and installation of the stabilizing system which secures the home against lateral and upward
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.

SIDEWALL VERTICAL ANCHORS
Homes designed for Wind Zones II and III also require vertical tie-downs along the side- conforms to
walls.The vertical tie-down anchor straps(or brackets for connecting to the home)are HUD iviHcss
factory installed and indicate the locations.Vertical and frame sidewall tie-downs may 1i15/09
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 re-
gardless 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
loads at the ends of the home. Use Table 23 to determine the number of end wall frame
anchors required at the each end of each home section. End wall frame tie-downs are
not required at Wind Zone I.

STEP 2. DETERMINE TIE-DOWN CONFIGURATION
There are two primary tie-down configurations:the near beam and the far beam meth-
ods. Skyline Corporation use the near beam method for all Wind Zone I applications.
The near beam method is also used at Wind Zones II and III,except when a unit has a 5
in 12 roof pitch,and then the far beam method is used. The two methods are described
below:
• Near Beam Method.Connect an anchor strap from the anchor head to the
beam closest to the anchor. (Figure 71). In addition for Wind Zones II and II,
connect a vertical sidewall strap from the sidewall of the home to the anchor
head using a double-headed anchor.
• Far Beam Method. Connect an anchor strap from the anchor head to the out-
side beam. (Figure 71). In addition for Wind Zones II and ll, connect a vertical
sidewall strap from the sidewall of the home to the anchor head using a double-
headed anchor. The far beam method is only required for double wide units at
Wind Zone II or III with a 5/12 roof pitch.

ASTM D3953-97,Type 1,Grade 1,Finish B with a minimum allowable working load capacity of 3,150 lbs
and a minimum ultimate load of 4,725 lbs.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 manufacturer,will be specified in the

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 util-
ity 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 anchor lo-
cations.Also check for homeowner-installed wires and pipes,such as those connecting Grading area

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 location
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 73).

vary from 10 feet to 18 feet,depending on the types of traffic anticipated below the ser-
vice 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 conduc-
tors 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 conduc-
tors enter the crawl space,a separate service disconnect may be required. Refer to
Table 25 for the conductor and junction box requirements.The installer must provide the
supply connection including the feeder conductors,junction box,and conduit 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 meas-
ured 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.

2. Review appliance instructions.Review each appliance manufacturer's in-
structions before the home is connected to the gas supply. Most gas appliances
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 86).
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 sup-
ply source exceeds,or could exceed this pressure,install a regulator if required
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.

3. Pressurize system.Using an air compressor, pressurize the system with com-
pressed 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 applying
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 de-
tergents,soap, or other household chemicals). If bubbles form,tighten the con-
nection and recheck.
6. Repair leaks. If leaks persist, replace defective pipes or fittings with sound ma-
terial 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 re-
move leak detection fluid.

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 1/2 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 re-
move leak detection fluid.

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 alarm is
provided for installation at a pre-wired location under the home.Connect the basement
smoke alarm and test all alarms as follows:
1. Check circuit. Ensure that electrical power to the home is activated and that
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 92). Use additional sec-
tion(s)of chimney pipe(not provided)if required by local code or if the site

In areas subject to freezing,the coverings for the ventilation openings must ing.
have an operable damper,permitting them to be in the open or closed posi-
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 X
area(or for each 1,500 square feet if a ground moisture retarder is installed r
according to STEP 2.INSTALL GROUND MOISTURE RETARDER, p.96). Z
Place vents as high above the ground as practical. m
4. Install access.Provide an access opening not less than 18 inches wide and p
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. Z
