CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors. Every 6
months, inspect the exhaust ducting and remove any lint build up.
C. DRYER ENCLOSURE
Bulkheads and partitions should be made of noncombustible materials.
D. AIR INTAKE
Make-up air will effect drying time, efficiency, and fire safety margins. Make-up air openings from an outside
source should be two (2) to three (3) times the cross section area of the exhaust on gas and electric dryers, and
four (4) to five (5) times the area for steam dryers. The dryer must be installed with provisions for adequate
combustion and make-up air supply.
E. EXHAUST DUCTING
Whenever possible, exhaust each dryer separately. Never reduce the air outlet diameter of the dryer.
Avoid 90º right angle turns in the ducting. Where turns are necessary, use 45º or 30º angles instead.
Avoid any screw or object that would protrude inside the exhaust duct and create a lint build up.
DO NOT use screws or caps on exhaust.
If the exhaust duct goes through the roof, it may be protected from the weather by using a 180º turn to point the
opening downward. If it goes through the wall, use a 90º turn to point the opening downward. (Refer to the
illustration below.) The dryer must be installed with a proper exhaust duct connection to the outside.
CAUTION: This dryer produces combustible lint and must be exhausted to the outdoors.
