Vent System Length
Maximum length of vent system depends upon the type of vent
used, number of elbows, and type of exhaust hood.

A 102 mm (4") outlet hood is preferred. However, a 64 mm
(2 1 ⁄ ") outlet exhaust hood may be used. A 64 mm (2

outlet creates greater back pressure than other hood types.
For permanent installation, a stationary vent system is required.
Multiple Dryer Venting
I A main vent can be used for venting a group of dryers.
Main vent should be sized to remove 5663 l/min (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 airflow of
all the dryers in the room.
I Back-draft Damper Kit, Part No. 3391910, is available from
your 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.

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 610 mm (2 ft.) above the highest part
of the building. The opening in wall or roof shall have a diameter
13 mm (1/2") larger than the vent diameter. The vent should be
centered in the opening.
Do not install screening or cap over the end of the vent.
Use sealing compound to seal exterior wall opening around
exhaust vent.
