Following are important instructions and information concerning the exhaust requirements for your dryer.
,_t Important Warning: To reduce the risk of fire, combustion, or accumulation of combustible gases, DO NOT
exhaust dryer air into an enclosed and unventilated area, such as an attic, wall, ceiling, crawl space, chimney, gas
vent, or concealed space of a building. To reduce the risk of fire, DO NOT exhaust the dryer with plastic or thin foil
ducting.

Exhaust Requirements and Instructions:
1. Venting materials are not provided with the dryer
and you should obtain the necessary venting
materials locally. For example, the outer end of
exhaust pipe must have a weather hood with
hinged dampers to prevent back-draft when the
dryer is not in use.
2. The exhaust duct must be four 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 your
new dryer.
3. Rigid metal duct is recommended. Do not install
flexible duct in concealed spaces.
Non-combustible flexible metal duct is
acceptable. Do not use plastic or thin foil ducting.
4. DO NOT use sheet metal screws on exhaust pipe
joints or other fastening means which extend into
the duct that could catch lint and reduce the
efficiency of the exhaust system. Secure all joints
with duct tape.
,
To maximize operating results, please observe the
duct length limitations noted in the chart above.
