WARNING
!
Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to follow these instructions can result in
death or fire.
The ductwork should be laid out in such a way that the
ductwork travels as directly as possible to the outdoors with
as few turns as possible. There should be a minimum
6-inch (15.24 cm) clearance between the dryer top and the
first bend in the ductwork for ease of servicing. Single or
independent dryer venting is recommended. It is suggested
that the use of 90° turns be avoided; use 30° and/or 45° bends
instead. The radius of the elbows should preferably be
1-1/2 times the diameter of the duct. All ductwork should be
smooth inside with no projections from sheet metal screws
or other obstructions, which will collect lint. When adding
ducts, overlap the duct being connected. All ductwork joints
must be taped to prevent moisture and lint from escaping
into the building. Back draft dampers must be installed in all
commonly ducted systems. Inspection doors should be
installed at strategic points in the exhaust ductwork for
periodic inspection and cleaning of lint from the ductwork.
IMPORTANT: It is recommended that exhaust or booster
fans not be used in the exhaust ductwork system.
Exhaust back pressure measured by a manometer/
magnehelic in the exhaust duct must be no less than 0 and
must not exceed 0.6 in WC (1.48 mb).
NOTE: When the exhaust ductwork passes through a wall,
ceiling, or roof made of combustible materials, the opening
must be 2-inches (5.08 cm) larger than the duct (all the
way around). The duct must be centered within this
opening.
The ductwork for this appliance must be suitable for the
appliance category in accordance with national installation
regulations of the country of destination.
Outside Venting Protection
To shelter the outside end of the horizontal ductwork from
the weather, a 90° elbow bent downward should be installed
where the exhaust exits the building. If the ductwork travels
vertically up through the roof, it should be protected from the
weather by using a 180° turn to point the opening downward.
In either case, allow at least twice the diameter of the duct
between the duct opening and the nearest obstruction (refer
to the diagram).
IMPORTANT: Do not use screens, louvers, or caps on the
outside opening of the exhaust ductwork.

Single Dryer Venting
IMPORTANT: For extended ductwork runs, the cross-
sectional area of the ductwork can only be increased to an
extent. When the ductwork approaches the maximum
limits as noted in this manual, a professional HVAC firm
should be consulted for proper venting information.
