Make-Up Air Requirements
A dryer exhausts 214 cfm (measured at back of dryer)
and sufficient make-up air must be supplied to replace air
exhausted by each dryer.
An unobstructed opening of at least 260 cm 2 (40 square
inches) of outdoor make-up air MUST be provided for
each dryer. Protective louvers in the opening to the
outdoors can reduce air movement approximately 35 to
40 percent. Be sure the opening is large enough to
compensate for any louvers.
If it is necessary to duct make-up air to the dryer, increase
the area of the ductwork by 25 percent to compensate for
any reduction in air movement. In addition, the make-up
air duct should extend down to within approximately two
feet from the floor, directly behind the dryer.
Exhaust System
IMPORTANT: Keep exhaust duct as short as
possible.
NOTE: Be certain old ducts are cleaned before
installing your new dryer.
For best drying results, recommended maximum length
of exhaust system is shown below.
To prevent backdraft when dryer is not in operation, outer
end of exhaust pipe must have a weather hood with
hinged dampers (obtain locally).
NOTE: Weather hood should be installed at least
30.5 cm (12 inches) above the ground. Larger
clearances may be necessary for installations where
heavy snowfall can occur.
Exhaust Direction
The dryer can be exhausted to the outdoors through the
back, left, right or bottom of the dryer. EXCEPTION:
Gas dryers cannot be vented out the left side because
of the burner housing.
Dryer is shipped from factory ready for rear exhaust; no
kits required.
Exhausting the dryer through sides or bottom can be
accomplished by installing a Directional Exhaust Kit
528P3 available as optional equipment at extra cost.
