Exhaust Requirements

A drying tumble dryer produces combustible lint. To
reduce the risk of fire, the tumble dryer must be ex-
hausted to the outdoors.
To reduce the risk of fire, DO NOT use plastic or thin
foil ducting to exhaust the tumbler.
To reduce the risk of fire and accumulation of com-
bustible gases, DO NOT exhaust tumble dryer air in-
to a window well, gas vent, chimney or enclosed, un-
ventilated area such as an attic wall, ceiling, crawl
space under a building, or concealed space of a
building.

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 grav-

ity vented appliances between tumble dryer(s) and make-up air
openings. If it is necessary to duct make-up air to tumble dry-
er(s), increase area of duct work by 25% to compensate for re-
strictions in air movement.

Venting

To reduce the risk of fire due to increased static
W059R1
pressure, we do not recommend installation of in-
line secondary lint filters or lint collectors. If secon-
dary systems are mandated, frequently clean the
system to assure safe operation.
IMPORTANT: Installing in-line filters or lint collectors
will cause increased static pressure. Failure to main-
tain 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 possi-
ble 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 B
flexible ducts - rigid metal ducts are recommended. Use exhaust
ducts made of sheet metal or other noncombustible material. DO
NOT use sheet metal screws or fasteners on exhaust pipe joints
which extend into the duct and catch lint. Use of duct tape or
