Venting Requirements

WARNING:
To reduce the risk of fire, this dryer MUST BE
EXHAUSTED OUTDOORS.
IMPORTANT: Observe all governing codes and ordinances.
The dryer exhaust must not be connected into any gas vent,
■
chimney, wall, ceiling, attic, crawlspace, or a concealed space
of a building. Only rigid or flexible vent shall be used for
exhausting.
Only a 4" (102 mm) heavy, metal exhaust vent and clamps
■
may be used.
Do not use an exhaust hood with a magnetic latch.
■
Use clamps to seal all joints. Do not use screws or other
■
fastening devices that extend into the interior of the duct
and catch lint. Do not use duct tape.
Do not use plastic or metal foil vent.
■
Rigid metal vent:
Recommended for best drying performance and to avoid
■
crushing and kinking.
Flexible metal vent (acceptable only if accessible to clean):
Must be fully extended and supported in final dryer location.
■
Remove excess to avoid sagging and kinking that may result
■
in reduced airflow and poor performance.
Do not install in enclosed walls, ceilings, or floors.
■
The total length should not exceed 7¾ ft. (2.4 m).
■
An exhaust hood should cap the vent to prevent rodents and
insects from entering the home or business.
Exhaust hood must be at least 12" (305 mm) from the ground
or any object that may be in the path of the exhaust (such as
flowers, rocks, or bushes).
If using an existing vent system, clean lint from the entire length
of the system and make sure exhaust hood is not plugged with
lint. Replace any plastic or metal foil vent with rigid metal or
flexible metal vent.
Plan installation to use the fewest number of elbows and turns.

INSTALLATION REQUIREMENTS INSTALLATION REQUIREMENTS
Allow as much room as possible when using elbows or making
turns. Bend vent gradually to avoid kinking.
Vent outlet is located at the back of the dryer, at bottom center.
The vent can be routed up, down, left, right, behind the dryer,
or straight out the back of the dryer. See "Product Dimensions"
in the "Location Requirements" section.
Make-up air:
Although each single-load dryer should have an unobstructed
outdoor air opening of 24 in
inch [6.5 cm ] per 1,000 Btu [252 kcal]), common make-up air
2
openings are also acceptable. Set up common openings so that
the make-up air is distributed equally to all of the dryers. Keep
in mind that the coverage area must be increased by 33% to
account for use of registers or louvers over the openings. Also,
make-up air openings should not be installed near the location
of exhaust vents exiting the building.
Vent System Length
Maximum length of vent system depends upon the type of
vent used, number of elbows, and type of exhaust hood.
The maximum length for rigid vent is shown in the chart.

For vent systems not covered by the vent specification chart,
see your parts distributor.
Provision must be made for enough air for combustion and
ventilation. (Check governing codes and ordinances.) See
"Recessed Area and Closet Installation Instructions" in the
"Location Requirements" sections.
A 4" (102 mm) outlet hood is preferred. However, a 2½" (64 mm)
outlet exhaust hood may be used. A 2½" (64 mm) outlet creates
greater back pressure than other hood types. For permanent
installation, a stationary vent system is required.

Connect Vent

1. If connecting to existing vent, make sure the vent is clean.
2. Using a 4" (102 mm) clamp, connect vent to exhaust outlet
in dryer.
NOTE: Do not remove vent collar.
