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.

W116

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.

W115

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.

W045

To reduce the risk of fire, DO NOT use plastic pipe or flexible plastic pipe to exhaust the dryer.

W041

Never install flexible duct in concealed spaces, such as a wall or ceiling.

Exhaust System Materials

Exhaust system materials are not supplied with the dryer unit.

Exhaust duct must be four inches (10.2 cm) in diameter having no obstructions. Rigid metal duct is recommended. Non-combustible semi-rigid flexible metal duct is acceptable. Do not use plastic pipe or flexible plastic pipe, because it contributes to poor drying performance and collects lint, which can lead to a fire hazard.

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.

NOTE: Kits described above are optional exhaust system materials available at extra cost.

Make-Up Air Requirements

A dryer unit exhausts 214 cfm (measured at back of dryer unit) and sufficient make-up air must be supplied to replace air exhausted by each dryer unit.

An unobstructed opening of at least 40 square inches (260 cm2) of outdoor make-up air MUST be provided for each dryer unit. Protective louvers in the opening to the outdoors can reduce air movement approximately 35 to 40 percent. Be sure the opening is large enough to compensate for any louvers.

If it is necessary to duct make-up air to the dryer unit, increase the area of the ductwork by 25 percent to compensate for any reduction in air movement. In addition, the make-up air duct should extend down to within approximately two feet from the floor, directly behind the dryer unit.
