Dryer Exhaust Requirements
Exhaust System Materials
Exhaust system materials are not supplied with the
unit.
Exhaust duct must be 4 in. (10.2 cm) in diameter
having no obstructions. Rigid metal duct is
recommended. Non-combustible flexible metal duct is
acceptable. Do not use plastic or thin foil ducting,
because it contributes to poor drying performance and
collects lint, which can lead to a fire hazard.
Never install flexible duct in concealed spaces, such as
a wall or ceiling.
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 duct joints with duct
tape or pop-rivets.
NOTE: Kits described above are optional exhaust
system materials available at extra cost.
