Mobile home installation
requirements
If codes permit, this appliance is suitable for mobile
home installations. The installation of the dryer must
conform to Manufactured Home Construction and
Safety Standard, Title 24 CFR, Part 3280 (formerly
the Federal Standard for Mobile Homes Construction
and Safety, Title 24, HUD Part 280) or latest edition.
The dryer must be fastened to the floor at time
of installation.
Order Mobile Home Installation Kit, Part No.
346765, from your dealer. Kit includes the necessary
fastening hardware and detailed installation
instructions. Metal exhaust system is also available
through your dealer.
Special provisions must be made for the introduction
of outside air into the dryer when installed in a
mobile home. The area of any opening for the
introduction of outside air (such as a nearby
window) should be at least twice as large as the
dryer exhaust opening.
The dryer must be exhausted outside.
Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to do so can result in death or fire.
WARNING
The exhaust vent must be securely fastened to a
non-combustible portion of the mobile home
structure. The exhaust system must not terminate
beneath the mobile home.

The maximum length
of the exhaust system depends
upon:
• the type of vent (rigid or flexible metal).
• the number of elbows used.
• side or bottom exhaust. Side or bottom exhaust
adds a 90° turn inside the dryer. To determine
maximum exhaust length, add one 90° turn to the
chart.
1. See the exhaust vent length chart that matches
your type hood for the maximum vent lengths you
can use.
Do not use vent runs longer than specified in
exhaust vent length charts.
Exhaust systems longer than specified will:
— accumulate lint creating a potential fire
hazard.
— shorten the life of the dryer.
— reduce performance, resulting in longer
drying times and increased energy usage.
2. Determine the number of elbows you will need.
3. In the column listing the type of metal vent you are
using (rigid or flexible), find the maximum length
of metal vent on the same line as the number of
elbows.
4. Determine the number of 4" clamps you will need.
The maximum length using a 2" x 6" rectangular
vent with 2 elbows and a 2-1/2" exhaust hood is
8 ft.
Plan the exhaust vent installation
Select the route that will provide the straightest
and most direct path outdoors.
Plan the installation
to use the fewest number of elbows and turns.
When using elbows or making turns,
allow as much
room as possible. Bend vent gradually to avoid
kinking.
For exhaust systems not covered by exhaust vent
length charts
(such as multiple unit hookups,
plenums, and power-assist fans), see Service
Manual, Part No. 603197. (To purchase the Service
Manual, see your Use and Care Guide for a toll-free
telephone number.)

Important: Observe all governing codes and
ordinances.
Exhaust your dryer to the outside.
Moisture and lint
indoors may cause:
• lint to gather around the dryer where it can be fuel
for a fire.
• moisture damage to woodwork, furniture, paint,
wallpaper, carpet, etc.
• housecleaning problems and health problems.
Dura Safe
TM
venting products are recommended
and are available from your dealer.
Four-inch diameter vent must be used.
Use a heavy metal vent.
Do Not use plastic or metal
foil vent.
Rigid metal vent is recommended
to prevent
crushing and kinking.
Flexible metal vent
must be fully extended and
supported when the dryer is in its final position.
Remove excess flexible vent to avoid sagging and
kinking that may result in reduced air flow.
An exhaust hood
should cap the
exhaust vent to prevent rodents and
insects from entering the home.
Exhaust outlet hood
must be at
least 12 inches from the ground or
any object that may be in the path
of the exhaust (such as flowers,
rocks or bushes, etc.).
If using an existing exhaust system, clean lint from
entire length of system and make sure exhaust
hood is not plugged with lint.
Replace any plastic or
metal foil vent with rigid metal or flexible metal vent.
Use clamps
to seal all joints. Do Not use duct tape,
screws or other fastening devices that extend into the
interior of the vent to secure vent.
Service check:
Back pressure in any exhaust system
used must not exceed 0.6 inches in water column
measured with an incline manometer at the point that
exhaust vent connects to dryer.

The exhaust outlet
is located at the center of the
rear of the dryer.
The exhaust vent
can be routed up, down, left,
right or straight out the back of the dryer. See
“Recessed area/closet installation” section, Panel A,
for general space requirements.
• Do Not use non-metal flexible vent, or exhaust
hoods with magnetic latches.
• Do Not exhaust dryer into any gas vent, chimney,
furnace, cold air vent, duct, wall, ceiling,
concealed space of a building, attic or crawl
space, or any other vent used for venting.
• Do Not install flexible vent in enclosed walls,
ceilings or floors.
