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.”

n
Shorten life of dryer.

Reduce performance, resulting in longer drying times
and increased energy usage.
