exhaust hoods with magnetic latches.
• Metal exhaust vent must be four inches
in diameter.
• Do Not exhaust dryer into a chimney,
furnace, cold air vent, attic or crawl space,
or any other vent used for venting.
• Do Not install flexible vent in enclosed
walls, ceilings or floors.
Plan the exhaust vent installation
Route the vent
exhaust
outlet
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.
Panel C
Important: Observe all governing codes and
ordinances.
Dryer MUST BE EXHAUSTED 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
venting products are
TM
recommended and are available from your
dealer.
Four-inch diameter vent is required.
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.

acceptable
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.
Determine vent length
The maximum length of the exhaust system
depends upon:
• the type of vent (rigid or flexible metal).
• the number of elbows used.
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.
Mobile home installation
