8_ Installing your dryer
DUCTING REQUIREMENTS
• Use a 4-inch (10.2 cm) diameter rigid aluminum or rigid galvanized steel duct.
• Do not use a smaller duct.
• Ducts larger than 4 inches (10.2 cm) in diameter can result in increased lint accumulation.
Lint accumulation should be cleaned regularly.
• If a flexible metal duct must be used, use the type with a stiff sheet metal wall. Do not use a flexible duct
with a thin foil wall. Serious blockage can result if the flexible metal duct is bent too sharply.
• Never install any type of flexible duct in walls, ceilings, or other concealed spaces.
• Keep the exhaust duct as straight and short as possible.
• Secure joints with duct tape. Do not use screws.
• DO NOT EXHAUST DRYER INTO ANY WALL, CEILING, CRAWL SPACE, OR CONCEALED SPACE OF
A BUILDING, GAS VENT, OR ANY OTHER COMMON DUCT OR CHIMNEY.
THIS COULD CREATE A FIRE HAZARD FROM LINT EXPELLED BY THE DRYER.
• Plastic flexible duct can kink, sag, be punctured, reduce airflow, extend drying times, and affect dryer operation.
• Exhaust systems longer than recommended can extend drying times, affect machine operation, and
may collect lint.
• The exhaust duct should end with an exhaust hood with a swing-out damper to prevent back drafts and
entry of wildlife. Never use an exhaust hood with a magnetic damper.
• The hood should have at least 12 inches (30.5 cm) of clearance between the bottom of the hood and
the ground or other obstruction. The hood opening should point down.
• Never install a screen over the exhaust outlet.
• To avoid lint buildup, do not exhaust the dryer directly into a window well. Do not exhaust under a house or porch.
• If exhaust ductwork must run through an unheated area, the duct should be insulated and slope slightly
down towards the exhaust hood to reduce condensation and lint buildup.
• Inspect and clean the interior of the exhaust system at least once a year. Unplug the power cord before cleaning.
• Check frequently to be sure the exhaust hood damper opens and closes freely.
• Check once per month, and clean at least one time per year. Note: If clothes are not getting dry, then
check ducting for obstructions.
