22 INSTALLATION
• If connecting to existing ductwork, make sure it
is suitable and clean before installing the dryer.
• Venting must conform to local building codes.
• Use only 4-inch (10.2 cm) rigid, semi-rigid or
flexible metal ductwork inside the dryer cabinet
and for venting outside.
• The exhaust duct must be 4 inches (10.2 cm) in
diameter with no obstructions. The exhaust duct
should be kept as short as possible. Make sure to
clean any old ducts before installing the new
dryer.
• Rigid, semi-rigid or flexible metal ducting is
recommended for use between the dryer and
the wall. All non-rigid metal transition duct must
be UL-listed. Use of other materials for transition
duct could affect drying time.
• DO NOT use sheet metal screws or other
fasteners which extend into the duct that could
catch lint and reduce the efficiency of the
exhaust system. Secure all joints with duct tape.
• Ductwork is not provided with the dryer. You
should obtain the necessary ductwork locally.
The vent hood should have hinged dampers to
prevent backdraft when the dryer is not in use.
• The total length of flexible metal duct must not
exceed 8 ft. (2.4 m).
• When pushing the dryer into the installed
position, do not crush or collapse ductwork.

• In Canada, only those foil-type flexible ducts, if
any, specifically identified for use with the
appliance by the manufacturer should be used.
In the United States, only those foil-type flexible
ducts, if any, specifically identified for use with
the appliance by the manufacturer and that
comply with the Outline for Clothes Dryer
Transition Duct, Subject 2158A, should be used.
Routing and Connecting Ductwork
Follow the guidelines below to maximize drying
performance and reduce lint buildup and
condensation in the ductwork. Ductwork and
fittings are NOT included and must be purchased
separately.
• Use 4-inch (10.2 cm) diameter rigid, semi-rigid or
flexible metal ductwork.
• The exhaust duct run should be as short as
possible.
• Use as few elbow joints as possible.
• The male end of each section of exhaust duct
must point away from the dryer.
• Use duct tape on all duct joints.
• Insulate ductwork that runs through unheated
areas in order to reduce condensation and lint
buildup on duct surfaces.
• Incorrect or inadequate exhaust systems are not
covered by the dryer warranty. Dryer failures or
service required because of such exhaust
systems will not be covered by the dryer
warranty.
