INSTALLATION REQUIREMENTS INSTALLATION REQUIREMENTS
3. Tighten hose clamp with Phillips screwdriver.
4. Make sure the vent is secured to exhaust hood with
a 4" (102 mm) clamp.
5. Move dryer into final position. Do not crush or kink vent.
Make sure dryer is level.
NOTE: Testing for proper ventilation should be done with a
Manometer. Minimum: 0.01" (0.2 mm). Maximum: 0.6" (16 mm).
For vent systems not covered by the vent specification chart,
see your 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" (102 mm) outlet hood is preferred. However, a 2½" (64 mm)
outlet exhaust hood may be used. A 2½" (64 mm) outlet creates
greater back pressure than other hood types. For permanent
installation, a stationary vent system is required.
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 ft. (610 mm) above the
highest part of the building.
The opening in the wall or
roof shall have a diameter
1/2" (13 mm) 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.

Multiple Dryer Venting
A main vent can be used for venting a group of dryers. The
■
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.
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 prevent 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°.

Air flow
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.
