IN CANADA AND IN THE UNITED STATES, THE RE-
QUIRED EXHAUST DUCT DIAMETER IS 4 IN (102 mm).
DO NOT USE DUCT LONGER THAN SPECIFIED IN THE
EXHAUST LENGTH TABLE.
Using exhaust longer than specified length will:
• Increase the drying times and the energy cost.
• Reduce the dryer life.
• Accumulate lint, creating a potential fire hazard.

• Terminate in a manner to prevent back drafts or entry of
birds or other wildlife.
• Termination should present minimal resistance to the ex-
haust air flow and should require little or no maintenance to
prevent clogging.
• Never install a screen in or over the exhaust duct. This
could cause lint build up.
• Wall caps must be installed at least 12 in. above ground
level or any other obstruction with the opening pointed
down.

• 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 can be made air and moisture-tight by wrap-
ping the overlapped joints with duct tape.
• Horizontal runs should slope down toward the outdoors ½
inch per foot.
