The “Vent System Chart” provides venting requirements that
will help achieve best drying performance.
NOTE: Side exhaust installations have a 90º turn inside the
dryer. To determine maximum exhaust length, add one 90º
turn to the chart.
Special provisions for mobile home installations:
The exhaust vent must be securely fastened to a noncombustible
portion of the mobile home structure and must not terminate
beneath the mobile home. Terminate the exhaust vent outside.
Determine vent path:
■ Select route that will provide straightest and most direct
path outdoors.
■ Plan installation to use fewest number of elbows and turns.
■ When using elbows or making turns, allow as much room
as possible.
■ Bend vent gradually to avoid kinking.
■ Use as few 90° turns as possible.
Determine vent length and elbows needed for best
drying performance:
■ Use following “Vent System Chart” to determine type of vent
material and hood combinations acceptable to use.
NOTE: Do not use vent runs longer than those specied
in “Vent System Chart.” Exhaust systems longer than those
specied will:
■ Shorten life of dryer.
■ Reduce performance, resulting in longer drying times
and increased energy usage.
INSTALL VENT SYSTEM
1. Install exhaust hood
12" min.
(305 mm)
12" min.
(305 mm)
2. Connect vent to exhaust hood
Install exhaust hood and use caulking compound to seal
exterior wall opening around exhaust hood.
Vent must t over the exhaust hood. Secure vent to exhaust
hood with 4" (102 mm) clamp. Run vent to dryer location using
straightest path possible. Avoid 90° turns. Use clamps to seal
all joints. Do not use duct tape, screws, or other fastening
devices that extend into interior of vent to secure vent,
because they can catch lint.
