Exhaust system setup
Hood or wall cap
■
■
Ensure the exhaust duct ends with a vent hood
with a swing out damper to prevent back drafts
and entry of wildlife.
■
■
Ensure there is minimal resistance to the exhaust
airflow. The structure should also require little or
no maintenance to prevent clogging.
■
■
Never place a screen in or over the duct.
■
■
The vent hood should have at least 12” (305 mm)
clearance between the bottom of the hood and
the ground or other obstruction.
■
■
The hood or wall cap should point downward.
Separation of turns
■
■
Separate all turns by at least 4 feet (1.2 m) of straight ducting (including the distance between
the last turn and the wall cap) to ensure the best performance of the dryer.
Turns other than 90°
■
■
One turn of 45
°
or less may be ignored.
■
■
Two 45
°
turns are to be considered equal to one 90
°
turn.
■
■
Each turn greater than 45
°
should be considered as equal to one 90
°
turn.
Important!
■
■
Choose a route that will provide the straightest and most direct path to the outdoors. Plan the
installation to use the fewest number of elbows and turns as possible.
■
■
When using elbows (rigid duct) or making turns (thick wall flexible metal duct), allow as much
room as possible. Bend thick wall flexible metal duct gradually to avoid kinking, and avoid
90
°
turns using this material.
