The “Vent System Chart” provides venting requirements that
will help achieve best drying performance.
Special provisions for mobile homes:
Exhaust vent must be securely fastened to a noncombustible
portion of mobile home and must not terminate beneath the
mobile home. Terminate exhaust vent outside.
Determine vent path:
n Select route that will provide straightest and most direct
path outdoors.
n Plan installation to use fewest number of elbows and turns.
n When using elbows or making turns, allow as much room
as possible.
n Bend vent gradually to avoid kinking.
n Use as few 90° turns as possible.
Determine vent length and elbows needed for best
drying performance:
Use the 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 specified
in “Vent System Chart.”
Exhaust systems longer than those specified will:
n Shorten life of dryer.
n Reduce performance, resulting in longer drying times
and increased energy usage.

Connect vent to exhaust hood
Install exhaust hood and use caulking compound to seal
exterior wall opening around exhaust hood.
Vent must fit 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.
CONNECT VENT
1.
Connect vent to exhaust outlet
Using a 4" (102 mm) clamp, connect vent to exhaust outlet
in dryer. If connecting to existing vent, make sure vent is
clean. Dryer vent must fit over dryer exhaust outlet and inside
exhaust hood. Check that vent is secured to exhaust hood
with a 4" (102 mm) clamp.
