EXHAUST INFORMATION 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 REAR EXHAUST LOCATION The dryers come ready for rear exhausting. Units have separate exhausts. duct. – Use only 4” rigid metal or UL-listed flexible metal – – – – – – – – (semi-rigid or foil-type) duct to connect the dryer to the home exhaust duct. It must be installed in accordance with these instructions and local codes. 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. The accumulated lint could create a fire hazard. 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. In special installations, it may be necessary to connect the dryer to the house vent using a flexible metal (foiltype) 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 in 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. EXHAUST LENGTH The MAXIMUM ALLOWABLE duct length and number of bends of the exhaust system depends upon the type of duct, number of turns, the type of exhaust hood (wall cap), and all conditions note below. The maximum allowable length for rigid metal duct is shown in the table below. More than two 90˚ turns is not recommended. The total length of flexible metal duct shall not exceed 8 ft.(2.4 m). In Canada and in the United States, the required exhaust duct diameter MAXIMUM LENGTH is 4in (102mm). EXHAUST NUMBER – HOOD TYPE – OF 90˚ TURNS A B RIGID METAL DUCT 0 45 ft. 30 ft. 35 ft. 20 ft. 4" DIAMETER 2 25 ft. 10 ft. PARTS AVAILABLE FROM LOCAL SERVICE ORGANIZATION • Rigid Metal Duct Components WX8X63 4" X 1' Duct WX8X51 4" Elbow WX8X64 4" x 2' Duct WX8X59 4" Aluminum Hood • Flexible Metal Duct Components WX08X10077 4" dia. flexible metal (semi-rigid) UL-listed transition duct (includes 2 elbows) EXHAUST INFORMATION (continued) EXHAUST SYSTEM CHECK LIST 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 air flow and should require little or no maintenance to prevent clogging. • Wall caps must be installed at least 12" above ground level or any other obstruction with the opening pointed down. SEPARATION OF TURNS Separate all turns by at least 3 ft. of straight duct, including distance between last turn and dampered wall cap. If two turns must be closer than 3 ft., deduct 10 ft. from the maximum lengths shown in the table for each occurrence. TURNS OTHER THAN 90˚ • One turn of 45˚ or less may be ignored. • Two 45˚ turns should be treated as one 90˚. • Each turn over 45˚ should be treated as one 90˚. 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 duct work with fasteners that extend into the duct. They will serve as a collection point for lint. • Duct joints can be made air and moisture-tight by wrapping the overlapped joints with duct tape. INSULATION Duct work which runs through an unheated area or is near an air conditioning duct should be insulated to reduce condensation and lint build up and be sloped down toward outdoors. NOTE: Never install screen inside exhaust duct. SIDE OR BOTTOM EXHAUST STEPS TO CHANGE DRYER TO SIDE OR BOTTOM EXHAUST DIRECTLY ON CABINET NOTE: Protect your hands and arms from sharp edges when working inside dryer cabinet. • Detach and remove the desired knockout. • Remove the screw inside the dryer exhaust duct end. Keep the screw for step 5. Pull on the duct to remove it. • Cut the duct as shown. Keep portion A. • Through the rear opening, locate the tab in the middle of the dryer base.
