EXHAUSTING THE DRYER (cont.)
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.
• Wall caps must be installed at least 12" (30.5 cm)
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. (1.2 m) of straight duct, including distance
between last turn and dampened exhaust hood
(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.
• Duct joints should be made air- and moisture-tight
by wrapping the overlapped joints with duct tape or
aluminum tape.
• Do not assemble ductwork with any fasteners that
extend into the duct. These fasteners can accumulate
lint, creating a potential fire hazard.
• Horizontal runs should slope down towards the
outdoors 1/4" (6.4 mm) per foot.
• 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.
INSULATION
• Ductwork that runs through an unheated area or is
near air conditioning should be insulated to reduce
condensation and lint build-up.
BEFORE YOU BEGIN
• Remove and discard existing plastic or metal foil
duct and replace with UL-listed duct.
• Remove any lint from the wall exhaust opening.

STANDARD REAR EXHAUST
We recommend that you install your dryer before
installing your washer. This will permit direct
access for easier exhaust connection.
Slide the end of the exhaust duct on the back of the
dryer and secure with duct tape or a hose clamp.

NOTE: We strongly recommend using rigid metal
exhaust duct. However, if flexible ducting is used it
must be UL-Listed metal, not plastic.
• For straight line installation, connect the dryer
exhaust to the external exhaust hood using duct
tape or clamp.
RECOMMENDED CONFIGURATION
TO MINIMIZE EXHAUST BLOCKAGE
Using duct elbows will prevent duct kinking and
collapsing.
