• A clothes dryer produces combustible lint and
must be exhausted outdoors.
• If codes permit, dryer may be installed in a
recessed area or closet using dimensions shown.
• Dimensions are in inches and are the minimum
allowable.
• Additional spacing should be considered for ease
of installation and servicing. Companion
appliance spacing should also be considered.
✔Observe all governing codes and ordinances.
✔Check code requirements: Some codes limit or
do not permit installation of clothes dryers in
garages, closets, mobile homes or sleeping
quarters. Contact your local building inspector.
Important: Observe all governing codes and
ordinances.
A four-wire or three-wire, single phase, 120/240volt, 60-Hz, AC-only, electrical supply (or four-wire
or three-wire, 120/208-volt if specified on
model/serial rating plate) is required on a separate
30-ampere circuit, fused on both sides of the line. A
time-delay fuse or circuit breaker is recommended.
If codes permit and a separate ground wire is
used, it is recommended that a qualified electrician
determine that the ground path is adequate.
✔Comply with the installation specifications and
dimensions.
✔Consider spacing requirements for companion
appliances.
✔Make sure you have everything necessary for proper
installation.
✔Properly install dryer.

Exhaust requirements
Typical installations
exhaust from the
rear of the dryer.
better
exhaust air flow
acceptable
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.
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 exhausted outside.

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.
It is recommended that you exhaust your dryer to
the outside for best performance. 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

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.
• Do Not use non-metal flexible vent, or exhaust
hoods with magnetic latches.
• Do Not exhaust dryer into a chimney, wall, ceiling,
furnace, cold air vent, duct, concealed space, attic
or crawl space, or any other vent used for venting.
• Do Not install flexible vent in enclosed walls,
ceilings or floors.
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.
12" min.
The exhaust vent must be securely fastened to a
non-combustible protion of the mobile home
structure and must not terminate beneath the
mobile home.
