Installation Instructions
EXHAUSTING THE DRYER
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
(semi-rigid 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 page 26
of this manual.
• 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.
• 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.
• This dryer comes ready for rear exhausting. If space
is limited, use the instructions on pages 29–31 to
exhaust directly from the sides or bottom of the
cabinet.

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.
