WARNING

This gas appliance contains or produces a chemical
or chemicals which can cause death or serious ill-
ness and which are known to the State of California
to cause cancer, birth defects, or other reproductive
harm. To reduce the risk from substances in the fuel
or from fuel combustion, make sure this appliance is
installed, operated, and maintained according to the
instructions in this manual.

W115

WARNING

To reduce the risk of fire, DO NOT use plastic or thin
foil ducting to exhaust the dryer.

W354

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.

W048

WARNING

To reduce the risk of fire due to increased static
pressure, we do not recommend installation of in-
line secondary lint filters or lint collectors. If secon-
dary systems are mandated, frequently clean the
system to assure safe operation.

W749

IMPORTANT: Installing in-line filters or lint collectors
will cause increased static pressure. Failure to main-
tain the secondary lint system will decrease dryer effi-
ciency and will void machine warranty.

• 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.

• Install backdraft dampers in multi-dryer installations.
• In mobile home installations, dryer exhaust duct must be se-

cured to mobile home structure.

• Dryer exhaust duct MUST NOT terminate under mobile

home.

• 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). In multi-dryer in-
stallations, all dryers connected to the main collector duct
should be operating when pressure is checked.

• 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.

• Energy efficient buildings with low air infiltration rates

should be equipped with an air exchanger that can accommo-
