Install exhaust hood
1.
Install exhaust hood and use caulking compound to seal
exterior wall opening around exhaust hood.
Connect vent to exhaust hood
2.
Vent must fit over the exhaust hood. Secure vent to exhaust
hood with 4" (102 mm) clamp. Run vent to dryer location
using straightest path possible. Avoid 90° turns. Use clamps
to seal all joints. Do not use duct tape, screws, or other
fastening devices that extend into interior of vent to secure
vent, because they can catch lint.
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 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.
