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:
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 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 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.
