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 back guard 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.
NOTE 1 Opening from combustible materials must be 2-inches (5.08 cm)
larger than the duct (all the way around). The duct must be centered
within this opening.
NOTE 2 Distance should be 2 times the diameter of the duct to the nearest
obstruction.
Multiple Dryer (Common) 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.
If it is not feasible to provide separate exhaust ducts for
each dryer, ducts from individual dryers may be channeled
into a "common main duct." The individual ducts should
enter the bottom or side of the main duct at an angle not
more than 45º in the direction of airflow. The main duct
should be tapered, with the diameter increasing before each
individual duct is added. The minimum diameter of the
individual ductwork must be at least 8-inches (20.32 cm).
IMPORTANT: No more than four dryers should be
connected to one main common duct.
