• DO NOT use plastic or thin foil ducting. Rigid 

metal duct is recommended.

• Locate dryer so exhaust duct is as short as 

possible.

• Be certain old ducts are cleaned before installing 

your new dryer.

• Use 102 mm (4 inch) diameter rigid or flexible 

metal duct.

• The male end of each section of duct must point 

away from the dryer.

• Use as few elbows as possible.
• Use duct tape or pop-rivets on all duct joints. DO 

NOT use sheet metal screws or fasteners on 

exhaust pipe joints which extend into the duct 

and catch lint.

• Ductwork that runs through unheated areas must 

be insulated to help reduce condensation and lint 

build-up on pipe walls.

• Install backdraft dampers in multi-dryer 

installations.

• In mobile home installations, dryer exhaust duct 

must be secured to mobile home structure.

• Dryer exhaust duct MUST NOT terminate under 

mobile home.

• Dryer exhausts 220 cfm (measured at back of 

dryer).

• DO NOT install flexible duct in concealed 

spaces, such as a wall or ceiling.

• Static pressure in exhaust duct should not be 

greater than 1.5 cm water column (.6 inches), 

measured with manometer placed on exhaust 

duct 61 cm (two feet) from dryer (check with 

dryer running and no load). In multi-dryer 

installations, all dryers connected to the main 

collector duct should be operating when pressure 

is checked.

• Exhausting dryer in hard-to-reach locations can 

be done by installing 521P3 Flexible Metal Vent 

Kit (available as optional equipment at extra 

cost).

• Sufficient make-up air must be supplied to 

replace the air exhausted by the dryer. The free 

area of any opening for outside air must be at 

least 260 cm

 (40 in

).

• Energy efficient buildings with low air 

infiltration rates should be equipped with an air 

exchanger that can accommodate on demand 

make-up air needs in the laundry room. These 

devices can be obtained through your building 

contractor or building material suppliers. 

• Do not draw make-up air from a room containing 

a gas fired water heater, a dry cleaner or a hair 

salon.
