1. Install exhaust hood

Install exhaust hood and use caulking compound to seal

exterior wall opening around exhaust hood.

2. Connect vent to exhaust hood

Vent must t 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 specied

in “Vent System Chart.” Exhaust systems longer than those

specied will:

■ Shorten life of dryer.

■ Reduce performance, resulting in longer drying times

and increased energy usage.
