Venting Requirements

WARNING
Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to follow these instructions can result in death
or fire.
WARNING:
To reduce the risk of fire, this dryer MUST BE
EXHAUSTED OUTDOORS.
4" (10.2 cm) heavy metal exhaust vent and clamps must be used.
DURASAFE™ vent products are recommended.
DURASAFE™ vent products can be purchased from your dealer
or by calling Whirlpool Parts and Accessories. For more
information, see the "Assistance or Service" section of this
manual.
The dryer exhaust must not be connected into any gas vent,
chimney, wall, ceiling, or a concealed space of a building.
Do not use an exhaust hood with a magnetic latch.
Do not install flexible metal vent in enclosed walls, ceilings or
floors.
Use clamps to seal all joints. Exhaust vent must not be
connected or secured with screws or other fastening devices
which extend into the interior of the duct. Do not use duct
tape.
IMPORTANT: Observe all governing codes and ordinances.
Improper venting can cause moisture and lint to collect
indoors, which may result in:
Moisture damage to woodwork, furniture, paint,
wallpaper, carpets, etc.
Housecleaning problems and health problems.
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 metal vent
to avoid sagging and kinking that can result in reduced airflow
and poor performance.
An exhaust hood should cap the vent to prevent rodents and
insects from entering the home.
Exhaust hood must be at least 12" (30.5 cm) from the ground or
any object that is in the path of the exhaust (such as flowers,
rocks or bushes, etc.).
If using an existing vent system, clean lint from the entire length
of the 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.
