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 °.

Keep air openings free of dry cleaning fluid fumes. Fumes create
acids which, when drawn through the dryer heating units, can
damage dryers and loads being dried.
A clean-out cover should be located on the main vent for periodic
cleaning of the vent system.
if an exhaust hood cannot be used:
The outside end of the main vent should have a sweep elbow
directed downward. If the main vent travels vertically through the
roof, rather than through the wall, install a 180° sweep elbow on
the end of the vent at least 2 feet (61 cm) above the highest part
of the building. The opening wall or roof shall have a diameter 1A"
(1.3 cm) larger than the vent diameter. The vent should be
centered in the opening.
