DRYER TO
EXHAUST
SYSTEM
Secure all joints with clamps or duct
tape. DO NOT use sheet metal
screws or other fastening means
which extend into the duct to attach
exhaust pipe joints. They could
catch lint and reduce the efficiency
of the exhaust system.
IMPORTANT: Keep exhaust duct
as short as possible.
Be sure old ducts are clean before
installing your new dryer.
Exhaust System Materials
Exhaust duct must be tour inches
(10.2 cm) in diameter without
obstructions. Rigid metal duct is
recommended. Non-combustible
semi-rigid flexible metal duct is
acceptable.
DO NOT use plastic pipe, foil pipe,
or flexible plastic pipe, because it
contributes to poor drying
performance and collects lint, which
can lead to a fire hazard. To identify
flexible foil or plastic duct, pinch the
coils of the duct between your
fingers. If the coils can be brought
together, do not use the duct.

To prevent backdraft when dryer is
not in operation, outer end of
exhaust pipe must have a weather
hood with hinged dampers (obtain
locally).
Weather hood should be installed
at least 12" (30.5 cm) above the
ground. Higher clearances may be
necessary in areas where heavy
snowfall can occur.
No extra system length
consideration is necessary when
exhausting through the roof. Use
MAXIMUM EXHAUST LENGTH
table to calculate system length.
Use a roof cap that provides air
flow equal to weather hood.
Exhaust Directions
Dryer can be exhausted to the
outdoors through the back, left,
right or bottom of the dryer.
Dryer is shipped from factory ready
for rear exhaust, No kits required.
To exhaust dryer through sides or
bottom, install a DK1 Sales
Accessory (Directional Exhaust Kit
528P3). Available as optional
equipment at extra cost.
