Installation Instructions EXHAUST SYSTEM CHECKLIST HOOD OR WALL CAP • Terminate in a manner to prevent back drafts or entry of birds or other wildlife. • Termination should present minimal resistance to the exhaust airflow and should require little or no maintenance to prevent clogging. • Never install a screen in or over the exhaust duct. • Wall caps must be installed at least 12″ above ground level or any other obstruction with the opening pointed down. SEPARATION OF TURNS • For best performance, separate all turns by at least 4 ft. of straight duct, including distance between last turn and dampened wall cap. SEALING OF JOINTS • All joints should be tight to avoid leaks. The male end of each section of duct must point away from the dryer. • Do not assemble the ductwork with fasteners that extend into the duct. They will serve as a collection point for lint. • Duct joints should be made air- and moisture-tight by wrapping the overlapped joints with duct tape or aluminum tape. • Horizontal runs should slope down towards the outdoors 1/4″ per foot. INSULATION • Ductwork that runs through an unheated area or is near air conditioning should be insulated to reduce condensation and lint buildup. Correct Do Incorrect Don't Don't Don't WARNING To reduce the risk of fire or personal injury: • This clothes dryer must be exhausted to the outdoors. • Use only 4″ rigid metal ducting for the home exhaust duct. • Use only 4″ rigid metal or UL-listed flexible metal (semirigid or foil-type) duct to connect the dryer to the home exhaust duct. It must be installed in accordance with the instructions found in "Connecting the Dryer to House Vent" on this page. • Do not terminate exhaust in a chimney, a wall, a ceiling, gas vent, crawl space, attic, under an enclosed floor, or in any other concealed space of a building. 12 WARNING • Never terminate the exhaust into a common duct with a kitchen exhaust system. A combination of grease and lint creates a potential fire hazard. • Do not use duct longer than specified in the exhaust length table. Longer ducts can accumulate lint, creating a potential fire hazard. • Never install a screen in or over the exhaust duct. This will cause lint to accumulate, creating a potential fire hazard. • Do not assemble ductwork with any fasteners that extend into the duct. These fasteners can accumulate lint, creating a potential fire hazard. • Do not obstruct incoming or exhausted air. • Provide an access for inspection and cleaning of the exhaust system, especially at turns and joints. Exhaust system shall be inspected and cleaned at least once a year. CONNECTING THE DRYER TO HOUSE VENT RIGID METAL TRANSITION DUCT • For best drying performance, a rigid metal transition duct is recommended. • Rigid metal transition ducts reduce the risk of crushing and kinking. UL-LISTED FLEXIBLE METAL (SEMI-RIGID) TRANSITION DUCT • If rigid metal duct cannot be used, then UL-listed flexible metal (semi-rigid) ducting can be used (Kit WX08X10077). • Never install flexible metal duct in walls, ceilings, floors or other enclosed spaces. • Total length of flexible metal duct should not exceed 8 feet (2.4 m). • For many applications, installing elbows at both the dryer and the wall is highly recommended (see illustrations at right). Elbows allow the dryer to sit close to the wall without kinking and/or crushing the transition duct, maximizing drying performance. • Avoid resting the duct on sharp objects. UL-LISTED FLEXIBLE METAL (FOIL-TYPE) TRANSITION DUCT • In special installations, it may be necessary to connect the dryer to the house vent using a flexible metal (foil-type) duct. A UL-listed flexible metal (foil-type) duct may be used ONLY in installations where rigid metal or flexible metal (semi-rigid) ducting cannot be used AND where a 4″ diameter can be maintained throughout the entire length of the transition duct. • In Canada and the United States, only the flexible metal (foil-type) ducts that comply with the "Outline for Clothes Dryer Transition Duct, Subject 2158A" shall be used.
