Install exhaust hood
1.
Install exhaust hood and use caulking compound to seal
exterior wall opening around exhaust hood.
The Vent system chart provides venting requirements that will
help achieve best drying performance.
Special provisions for mobile home installations:
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 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 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.
NOTE: Side and bottom exhaust installations for 27" wide
models have a 90º turn inside the dryer. To determine
maximum exhaust length, add one 90º turn to the chart.
