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.
Exhausting the dryer through sides or bottom can be
accomplished by installing a Directional Exhaust Kit,
528P3, available as optional equipment at extra cost.
Exhaust System
For best drying results, recommended maximum
length of exhaust system is shown in
Table 1 .
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
12 inches (30.5 cm) above the ground. Larger
clearances may be necessary for installations where
heavy snowfall can occur.
