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. This unit is fitted with an integral back
draft damper (inside the 8-inch [20.32 cm] exhaust
connection). 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 dryer 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.
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.
