EXHAUSTING THE DRYER
WARNING –
To reduce the
risk of fire or personal injury:
• This dryer must be exhausted to the outdoors.
• Use only metal duct.
• Do not terminate exhaust into a chimney, any
gas vent, under an enclosed floor, in a crawl
space, wall, ceiling, into an attic or other
concealed space of a building. The accumulated
lint could create a fire hazard.
• Provide an access for inspection and cleaning
of the exhaust system, especially at turns.
Inspect and clean at least once a year.
• Never terminate the exhaust into a common
duct with a kitchen exhaust. A combination
of lint and grease could create a fire hazard.
• Do not obstruct incoming or exhausted air.
• This dryer comes ready for rear exhausting.
If space is limited, use the instructions
on pages 28–31 to exhaust directly
from the sides or bottom of the cabinet.
TOOLS AND MATERIALS YOU WILL
NEED TO INSTALL EXHAUST DUCT
❒ Phillips-head screwdriver
❒ Duct tape or duct clamp
❒ Rigid or UL-listed flexible
metal 4
″
(10.2 cm) duct
❒ Vent hood
❒ Drill with 1/8
″
drill bit
(for bottom venting)
❒ Hacksaw
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.
• If roof vents or louvered plenums are used, they
must be equivalent to a 4
″
dampened wall cap in
regard to resistance to airflow, prevention of back
drafts and maintenance required to prevent
clogging.
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.
For turns less than 4 ft. apart, see the Ducting
Component Equivalency Chart.
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
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.
