Determine vent path
Select the route that will provide the
straightest and most direct path outdoors.
Plan the installation to use the fewest num-
ber of elbows and turns.
When using elbows or making turns, allow
as much room as possible.
Bend vent gradually to avoid kinking.
Use the fewest 90° turns 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.

Special provisions for mobile home instal-
lations
The exhaust vent must be securely fastened to
a noncombustible portion of the mobile home
structure and must not terminate beneath the
mobile home. Terminate the exhaust vent out-
side.
NOTE: Do not use vent runs longer than
those specified in the Vent system chart.
Exhaust systems longer than those speci
-
fied will:
Shorten the life of the dryer.
Reduce performance, resulting in longer
drying times and increased energy us
-
age.
The Vent system chart provides venting re
-
quirements that will help to achieve the best
drying performance.
Vent system chart
NOTE: Bottom exhaust performance is equiv-
alent to adding two elbows. To determine
maximum exhaust length, add two elbows to
the chart.
NOTE: Performance of rear exhaust to ei-
ther side of the dryer is equivalent to adding
one elbow. To determine maximum exhaust
length, add one elbow to the chart.
