WARNING
To reduce the risk of fire, the exhaust duct and
weather hood MUST be fabricated of a material that
will not support combustion. Rigid or flexible metal
pipe is recommended for a clothes dryer.

• DO NOT use plastic, thin foil or type B ducting. Rigid metal
duct is recommended.
• Locate dryer so exhaust duct is as short as possible.
• Be certain old exhaust ducts are cleaned before installing your
new dryer.
• Use 4 inch [102 mm] diameter rigid or flexible metal duct.
• The male end of each section of duct must point away from
the dryer.
• Use as few elbows as possible.
• Use of duct tape or pop-rivets on all seams and joints is rec-
ommended, if allowed by local codes. DO NOT use sheet
metal screws or fasteners on exhaust pipe joints which extend
into the duct and catch lint.
• Ductwork that runs through unheated areas must be insulated
to help reduce condensation and lint build-up on pipe walls.
• In mobile home installations, dryer exhaust duct must be se-
cured to mobile home structure.
• Dryer exhaust duct MUST NOT terminate under mobile
home.
• Exhaust duct must not be connected to any other duct, vent, or
chimney.
• Dryer exhausts 220 cfm per unit (measured at back of dryer).
• DO NOT install flexible duct in concealed spaces, such as a
wall or ceiling.
• Static pressure in exhaust duct should not be greater than 0.6
inches water column [1.5 cm water column], measured with
manometer placed on exhaust duct 2 feet [610 mm] from dry-
er (check with dryer running and no load).
• Exhausting dryer in hard-to-reach locations can be done by
installing 521P3 Flexible Metal Vent Kit (available as option-
al equipment at extra cost).
• Sufficient make-up air must be supplied to replace the air ex-
hausted by the dryer. The free area of any opening for outside
air must be at least 40 in.

• Failure to exhaust dryer properly will void warranty.

area exposed to the conditioned air.
NOTE: Venting materials are not supplied with the dry-
er (obtain locally).
IMPORTANT: DO NOT block the airflow at the bottom of
the dryer’s front panel with laundry, rugs, etc. Blockage
will decrease airflow through the dryer, thus reducing
the efficiency of the dryer.
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 accomplish-
ed by installing a Directional Exhaust Kit, 528P3, available as
optional equipment at extra cost.
Exhaust System
For best drying results, recommended maximum length of ex-
haust system is shown in Table 2 .
To prevent backdraft when dryer is not in operation, outer end of
exhaust pipe must have a weather hood with hinged dampers (ob-
tain locally).
NOTE: Weather hood should be installed at least 12 in-
ches [305 mm] above the ground. Larger clearances
may be necessary for installations where heavy snow-
fall can occur.
