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 in table 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 12 inches (30.5 cm) 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.
Installation
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 DK1 Sales Accessory (Directional Exhaust Kit 528P3) available as optional equipment at extra cost.
