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 cause 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. • 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 the 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. • 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.
