Dryer Exhaust Requirements
WARNING
A clothes dryer produces combustible lint.
To reduce the risk of fire and combustion
gas accumulation the dryer MUST be
exhausted to the outdoors.
This gas appliance contains or produces a
chemical or chemicals which can cause
death or serious illness 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.
To reduce the risk of fire and the
accumulation of combustion gases, DO NOT
exhaust dryer air into a window well, gas
vent, chimney or enclosed, unventilated
area, such as an attic, wall, ceiling, crawl
space under a building or concealed space
of a building.
To reduce the risk of fire, DO NOT use
plastic or thin foil ducting to exhaust the
dryer.
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.
