■ The dryer vent 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.
■ 4" (10.2 cm) heavy metal vent and clamps must be used.
■ Use clamps to seal all joints. Vent must not be connected or
secured with screws or other fastening devices which extend
into the interior of the vent. Do not use duct tape.
IMPORTANT: Observe all governing codes and ordinances.
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 may result in reduced airflow
and poor performance.
An exhaust hood should cap the vent to prevent rodents and
insects from entering the home or business.
Exhaust hood must be at least 12" (30.5 cm) from the ground or
any object that may be in the path of the exhaust (such as
flowers, rocks or bushes).
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
For vent systems not covered by the vent specification chart, see
Whirlpool Service Manual, “Exhausting Whirlpool Dryers,” Part
No. LIT603197, available from your Whirlpool parts distributor.
If dryer is installed in a confined area, such as a bedroom,
bathroom or closet, provision must be made for enough air for
combustion and ventilation. (Check governing codes and
ordinances.) See “Recessed Area and Closet Installation
Instructions” in the “Location Requirements” section.
A 4" (10.2 cm) outlet hood is preferred. However, a 2¹⁄₂" (6.4 cm)
outlet exhaust hood may be used. A 2¹⁄₂" (6.4 cm) outlet creates
greater back pressure than other hood types. For permanent
installation, a stationary vent system is required.
Multiple Dryer Venting
■ A main vent can be used for venting a group of dryers. Main
vent should be sized to remove 200 CFM of air per dryer.
Large-capacity lint screens of proper design may be used in
the main vent if checked and cleaned frequently. The room
where the dryers are located should have make-up air equal
to or greater than the CFM of all the dryers in the room.
■ Back-draft Damper Kits, Part No. 3391910, are available from
your Whirlpool dealer and should be installed in each dryer's
vent to prevent exhausted air from returning into the dryers
and to keep the exhaust in balance within the main vent.
Unobstructed air openings are required.
Each vent should enter the main vent at an angle pointing in the
direction of the airflow. Vents entering from the opposite side
should be staggered to reduce the exhausted air from interfering
with the other vents.
The maximum angle of each vent entering the main vent should
be no more than 30°.
