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 A back-draft damper kit is needed and is available from a
commercial laundry distributor; it should be installed in the
vent of each dryer to keep exhausted air from returning
into the dryers and to keep the exhaust in balance within
the main vent. Unobstructed return 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 items being dried.
A clean-out cover should be located on the main vent for periodic
cleaning of the vent system.
INSTALLATION INSTRUCTIONS – ELECTRIC DRYER
Install Leveling Legs
NOTE: Slide dryer onto cardboard or hardboard before moving
to avoid damaging floor covering.
1. Using two or more people, move dryer to desired installation
location.
2. Take tape off front corners of dryer. Open dryer and remove
the literature and parts packages. Wipe the interior of the
drum thoroughly with a damp cloth.
3. Take two of the cardboard corners from the carton and place
them on the floor in back of the dryer. Firmly grasp the body
of the dryer and gently lay it on its back on the cardboard
corners.

G. Roof

of building
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.
4. With one of the legs in hand, check the ridges for a diamond
marking. That's how far the leg is supposed to go into the
hole.
5. Start to screw the leveling legs into the holes by hand.
(Use a small amount of liquid detergent to lubricate the screw
threads so it is easier to turn the legs.) Use a 25 mm (1")
wrench or socket wrench to finish turning the legs until you
reach the diamond mark. Then fit a protective foot boot over
each foot.
Now stand the dryer up.
6. Remove cardboard or hardboard from under dryer. Adjust the
legs of the dryer up or down until the dryer is level.
