• DO NOT use plastic or thin foil ducting. Rigid
metal duct is recommended.
• Locate dryer so exhaust duct is as short as
possible.
• Be certain old 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 duct tape or pop-rivets on all duct joints. DO
NOT use sheet metal screws or fasteners on
exhause pipe joints which extend into the duct.
• 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 secured to mobile home structure.
• Dryer exhaust duct MUST NOT terminate under
mobile home.
• Dryer exhausts 220 cfm (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 .6 inches water column (1.5 cm),
measured with manometer placed on exhaust
duct two feet (61 cm) from dryer (check with
dryer running and no load). In multi-dryer
installations, 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 optional equipment at extra
cost).
• Sufficient make-up air must be supplied to
replace the air exhausted by the dryer. The free
area of any opening for outside air must be at
least 40 in
2 (260 cm 2 ).
• Energy efficient buildings with low air
infiltration rates should be equipped with an air
exchanger that can accommodate on demand
make-up air needs in the laundry room. These
devices can be obtained through your building
contractor or building material suppliers.
• Do not draw make-up air from a room containing
a gas fired water heater, a dry cleaner or a hair
salon.
• Failure to exhaust dryer properly will void
warranty.
NOTE: Venting materials are not supplied with the
dryer (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.
