3.3 Exhausting requirements
WARNING
- The dryer shall not be exhausted into a chimney, a wall, a ceiling, an attic, a crawl space, or
a concealed space of a building.
- The dryer must be exhausted to the outside to reduce the risk of fire when installed in alcove
or closet.
Exhausting the dryer to the outside will prevent large amounts of lint and moisture from being
blown into the room.
- NEVER USE A PLASTIC OR NON-METAL FLEXIBLE DUCT
- If your existing ductwork is plastic, non-metal, or combustible, replace it with metal.
- Use only a metal exhaust duct that is non-flammable to ensure containment of the exhaust
air heat, and lint.
- Refer to the “Ducting requirements” section on page 8 for the maximum duct length and
number of bends.
- All dryers must be exhausted to the outside.
- Do not assemble the duct with screws or other fastening means that extend into the duct and
catch lint.
- The exhaust duct should be 4 inches (102mm) in diameter.
- The total length of flexible metal duct shall not exceed 7.8 feet (2.4 meters).
For usage in United States:
- Use only those foil-type flexible ducts, if any, specifically identified for use with the appliance
by the manufacturer and that comply with the outline for Clothes Dryer Transition Ducts,
Subject 2158A, shall be used.
