EXHAUST DUCT LENGTH INFORMATION
• The MAXIMUMALLOWABLElength 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. More than three 90° turns are not recommended.

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 over the exhaust duct.
• Wall caps must be installed at least 12" above ground
level or any other obstruction with the opening pointed
down.
TURNS OTHER THAN
90 °
• One turn of 45 ° or less may be ignored.
• Two 45° turns should be treated as one 90 °.
CONNECTING
THE DRYER TO HOUSE VENT
Rigid Metal Transition Duct
• For best drying performance, a rigid metal transition
duct is recommended.
• Rigid metal transition ducts reduce the risk of crushing
and kinking.
UL-Listed Flexible Metal (Semi-Rigid)Transition Duct
• If rigid metal duct cannot be used, then UL-listed
flexible metal (semi-rigid) ducting can be used (Kit
WX08X10077).
• Never install flexible metal duct in walls, ceilings, floors
or other enclosed spaces.
• Total length of flexible metal duct should not exceed
8 feet (2.4 m).
• For many applications, installing elbows at both the
dryer and the wall is highly recommended. Elbows
allow the dryer to sit close to the wall without kinking
and or crushing the transition duct, maximizing drying
performance.
• Avoid resting the duct on sharp objects.
CONNECTING
THE DRYER TO HOUSE VENT
(CONT.}
UL-Listed Flexible Metal (Foil-Type)Transition Duct
• In special installations, it may be necessary to connect
the dryer to the house vent using a flexible metal
(foil-type) duct. A UL-listed flexible metal (foil-type)duct
may be used ONLYin installations where rigid metal
or flexible metal (semi-rigid) ducting cannot be used
AND where a 4" diameter can be maintained
throughout the entire length of the transition duct.
• In Canada and the United States, only the flexible
metal (foil-type) ducts that comply with the "Outline for
Clothes Dryer Transition Duct, Subject 2158A" shall be
used.
• Never install flexible metal duct in walls, ceilings, floors
or other enclosed spaces.
• Total length of flexible metal duct should not exceed
8 feet (2.4 m).
• Avoid resting the duct on sharp objects.
For best drying performance:
1. Slide one end of the duct over the clothes dryer outlet
pipe.
2. Secure the duct with a clamp.
3. With the dryer in its permanent position, extend the
duct to its full length. Allow 2" of duct to overlap the
exhaust pipe. Cut off and remove excess duct. Keep
the duct as straight as possible for maximum airflow.
4. Secure the duct to the exhaust pipe with the other
clamp.
SEALING
OF JOINTS
• All joints should be tight to avoid leaks.
NOTE: T he male end of each section of duct must point
away from the dryer.
• Do not assemble 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.
INSULATION
• Ductwork that runs through an unheated area or
is near an air conditioning duct should be insulated
to reduce condensation and lint buildup.
