The Vent System Charts provide venting requirements that
will help achieve best drying performance.
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.
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.
