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

through wall, install a 180° sweep elbow on end of vent at least
2 ft. (610 mm) above surface of roof.

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 (air supply) equal to or greater than CFM of all the dryers
in the room.
Back-draft dampers are available from your distributor and
should be installed in the vent of each dryer to keep exhausted
air from returning into dryers and to keep exhaust in balance
within main vent. Unobstructed return air openings are required.
Although usually each single-load dryer should have an
unobstructed outdoor air opening of 24 in.

air openings are also acceptable. Set up common openings so
the make-up air is distributed equally to all of the dryers. Keep
in mind that the coverage area must be increased by 33% to
account for the use of registers or louvers over the openings.
Also, make-up air openings should not be installed near the
location where exhaust vents exit the building.
Each vent should enter the main vent at an angle pointing in the
