EXHAUST INFORMATION

WARNING -
THE UNITED STATES, THE REQUIRED EX-
HAUST DUCT DIAMETER IS 4 IN (102mm). 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.
The correct exhaust installation is YOUR
RESPONSIBILITY. Problems due to incorrect
installation are not covered by the warranty.
Remove and discard existing plastic or metal foil
transition duct and replace with UL listed transition
duct.
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 noted below. The
maximum duct length for rigid metal duct is shown in
the table below.

EXHAUST INFORMATION (cont)
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.
•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.
SEPARATION OF TURNS
For best performance, separate all turns by at least 4 ft.
of straight duct, including distance between last turn and
exhaust hood.
TURNS OTHER THAN 90º
• One turn of 45º or less may be ignored.
• Two 45º turns should be treated as one 90º turn.
• Each turn over 45º should be treated as one 90º turn.
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 can be made air and moisture-tight by
wrapping the overlapped joints with duct tape.
• Horizontal runs should slope down toward the outdoors
½ inch per foot
INSULATION
Duct work that runs through an unheated area or is
near air conditioning should be insulated to reduce
condensation and lint build-up.
