CONNECT 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.
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 considera-
tion is necessary when exhausting
through the roof. Use MAXIMUM
EXHAUST LENGTH table to calcu-
late system length. Use a roof cap
that provides air flow equal to
weather hood.
Exhaust Directions
Dryer can be exhausted to the out-
doors through the back, right, or
bottom of the dryer. 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.
To exhaust dryer through sides or
bottom, install a DK1 Sales
Accessory (Directional Exhaust Kit
528P3). Available as optional equip-
ment at extra cost.
Exhaust System Materials
Exhaust duct must be four inches
(10.2 cm) in diameter without
obstructions. Rigid metal duct is
recommended. Non-combustible
semirigid flexible metal duct is
acceptable.
DO NOT use plastic pipe, foil pipe,
or flexible plastic pipe, because it
contributes to poor drying perform-
ance 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 fin-
gers. If the coils can be brought
together, do not use the duct.
