Exhaust Requirements

WARNING

A drying tumbler produces combustible lint. To reduce the risk of fire, the tumbler must be exhausted to the outdoors.

W057

To reduce the risk of fire and accumulation of combustible gases, DO NOT exhaust tumbler air into a window well, gas vent, chimney or enclosed, unventilated area such as an attic, ceiling, crawl space under a building, or concealed space of a building.

W506

Make-Up Air

IMPORTANT: Do not obstruct the flow of combustion and ventilation air.

A tumbler is forced air exhausted and requires provisions for make-up air to replace the air exhausted by the tumbler.

Table 2

Make-up air openings with louvers will restrict air flow. The opening must be increased to compensate for area taken up by louvers.

If it is necessary to duct make-up air to tumbler(s), increase area of ductwork by 25% to compensate for any restriction in air movement.

Installation/Operation Supplement

Venting

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 to prevent the accumulation of lint.

DO NOT use plastic or thin foil flexible ducts. Use exhaust ducts made of sheet metal or other noncombustible material. Use duct tape or pop rivets on all seams and joints.

Verify that old ducts are thoroughly cleaned out before installing new tumbler(s).

NOTE: The ducts must be equivalent in strength and corrosion resistance to ducts made of galvanized sheet steel not less than 0.495 mm (0.0195 inches) thick.

IMPORTANT: For best performance, provide an individual exhaust duct for each tumbler. Do not install a hot water heater in a room containing tumblers. It is better to have the water heater in a separate room with a separate air inlet.

NOTE: This manual is only a supplement. Refer to installation/operation manual for full instructions.
