DRYER VENTING REQUIREMENTS

If an Exhaust Hood Cannot be Used

The outside end of main vent should have a sweep elbow directed downward.

12" min. 24" min. (305 mm)* (610 mm)

*Minimum clearance above any accumulation of snow, ice, or debris such as leaves

If main vent travels vertically through the roof, rather than through wall, install a 180° sweep elbow on end of vent at least 2 ft. (610 mm) above surface of roof.

The opening in wall or roof shall have a diameter 1⁄2" (13 mm) larger than vent diameter. Vent should be centered in opening.

Do not install screening over end of vent for best performance.

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 main vent if checked and cleaned frequently. The room where the dryers are located should have make-up air equal to or greater than CFM of all the dryers in the room.

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.

Back-draft Damper Kit, Part No. 3391910, is available from
your distributor and should be installed in the vent of each	30˚ max.
dryer to keep exhausted air from returning into dryers and to
keep exhaust in balance within main vent. Unobstructed return	air ￿ow
air openings are required.

The maximum angle of each vent entering the main vent should be no more than 30°.
