Exhaust Requirements
WARNING
A drying tumble dryer produces combustible lint.
To reduce the risk of fire, the tumble dryer must be
exhausted to the outdoors.
W057R1
WARNING
To reduce the risk of fire, DO NOT use plastic or
thin foil ducting to exhaust the tumbler.
W773
WARNING
To reduce the risk of fire and accumulation of
combustible gases, DO NOT exhaust tumble
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.
W059R1
Layout
Whenever possible, install tumble dryers along an outside wall
where duct length can be kept to a minimum, and make-up air
can be easily accessed. Construction must not block the airflow
at the rear of the tumble dryer. Doing so would prevent adequate
air supply to the tumble dryer combustion chamber.
Make-Up Air
A tumble dryer is forced air exhausted and requires provisions
for make-up air to replace air exhausted by tumble dryer.
IMPORTANT: Do not obstruct flow of combustion and
ventilation air.

Make-up air openings with louvers will restrict airflow. The
opening must be increased to compensate for area taken up by
louvers.
Make-up air openings in rooms containing tumble dryer(s) and/
or gas fired hot water heater or other gravity vented appliances
must be increased sufficiently to prevent downdrafts in any of
the vents when all tumble dryers are in operation. Do not locate
gravity vented appliances between tumble dryer(s) and make-
up air openings. If it is necessary to duct make-up air to tumble
dryer(s), increase area of duct work by 25% to compensate for
restrictions in air movement.
Venting
WARNING
To reduce the risk of fire due to increased static
pressure, we do not recommend installation of
in-line secondary lint filters or lint collectors. If
secondary systems are mandated, frequently clean
the system to assure safe operation.
W749
IMPORTANT: Installing in-line filters or lint collectors
will cause increased static pressure. Failure to
maintain the secondary lint system will decrease
tumble dryer efficiency and may void machine
warranty.
For maximum efficiency and minimum lint accumulation,
tumble dryer air must be exhausted to the outdoors by the
shortest possible route.
Proper sized exhaust ducts are essential for proper operation. All
elbows should be sweep type. Exhaust ducts must be assembled
so the interior surfaces are smooth, so the joints do not permit
the accumulation of lint. DO NOT use plastic, thin foil or Type
