INSTALLATION REQUIREMENTS
WARNING: To reduce the risk of re, this dryer MUST BE
EXHAUSTED OUTDOORS.
IMPORTANT: Observe all governing codes and ordinances.
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 exible metal vent shall be used for
exhausting.
■ Only a 4" (102 mm) heavy, metal exhaust vent and clamps
may be used.
■ 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 nal dryer location.
■ Remove excess to avoid sagging and kinking that may result
in reduced airow and poor performance.
■ Do not install in enclosed walls, ceilings, or oors.
■ The total length should not exceed 7
3
⁄
4
ft. (2.4 m).
NOTE: If using an existing vent system, clean lint from entire
length of the system and make sure exhaust hood is not
plugged with lint. Replace plastic or metal foil vents with rigid
metal or exible metal vents. Review “Vent System Chart” and
if necessary, modify existing vent system to achieve best drying
performance.
NOTE: Although each single-load dryer should typically have
an unobstructed outdoor air opening of 24" (154 cm) (based
on 1" [6.5 cm] per 1,000 Btu [252 kcal]), common make-up air
openings are also acceptable.
Set up common openings so the make-up air is distributed
equally to all dryers. Coverage area must be increased by 33%
to account for the use of registers or louvers.
Make-up air openings should not be installed near the building
exits for exhaust vents.
4"

4" (102 mm) heavy, metal exhaust vent
Elbows:
■ 45° elbows provide better airow than 90° elbows.
Clamps:
■ Use clamps to seal all joints.
■ Exhaust vent must not be connected or secured with screws
or other fastening devices that extend into interior of duct
and catch lint. Do not use duct tape.
Improper venting can cause moisture and lint to collect
indoors, which may result in:
Moisture damage to woodwork, furniture, paint, wallpaper,
carpets, etc.
Housecleaning problems and health problems.
