A WARNING
M
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.
Do Not use non-metal flexible vent, metal
vent that is smaller than four inches
(10.2 cm) in diameter or exhaust hoods
with magnetic latches.
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.
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.
Four-inch (10.2 cm) diameter vent is required
for best performance.
Rigid or flexible metal exhaust vent must be
used. Do Not use plastic or foil-covered 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
exhausted air from returning
to the dryer.
Exhaust outlet hood must be
at least 12 inches (30.5 cm)
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 vinyl or metallized plastic foil vent with rigid
metal or flexible metal vent.
Use duct tape to seal all joints. Do Not use
screws 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.
Mobile home installation
requirements
Four-wire power supply cord or cable must be
used in a mobile home installation.
The dryer must be exhausted outside.
If dryer is exhausted through the floor and the
area under the mobile home is enclosed, the
exhaust system must terminate outside.
Extension beyond the enclosure is
recommended to prevent lint and moisture
buildup under the mobile home.
Plan the exhaust vent installation
Route the vent
The exhaust outlet is located at the center of
the rear of the dryer.
better — good
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. Avoid making 90° 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.
