The Vent system chart provides venting requirements that will
help achieve best drying performance.
noTE:
Side and bottom exhaust installation have a 90° turn
inside the dryer. To determine maximum exhaust length, add
a 90° turn to the total number of elbows when referemcing
the chart.
Bottom exhaust installation
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 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.
