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.
Mobile home exhaust installation
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 specified
in Vent System Chart. Exhaust systems longer than those
specified will:
■
Shorten life of dryer.
■
Reduce performance, resulting in longer drying times
and increased energy usage.
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.
