Exhaust hoods:
Elbows:
Recommended Styles:
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.
An exhaust hood should cap the vent to keep rodents and ■
insects from entering the home.
Must be at least 12" (305 mm) from ground or any object ■
that may obstruct exhaust (such as owers, rocks, bushes,
or snow).
Do not use an exhaust hood with a magnetic latch. ■

Acceptable Style:
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).
The length of exible metal vent used must be included in ■
the overall vent system design as shown in the “Vent System
Chart”.
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.
