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
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
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.
The "Vent System Chart" provides venting requirements that will help
achieve best drying performance.

Install Vent System
Install exhaust hood
Install exhaust hood and use caulking compound to seal exterior
wall opening around exhaust hood.
Connect vent to exhaust hood
Vent must fit inside 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.
Connect vent to exhaust outlet
Using a 4" (102 mm) clamp, connect vent to exhaust outlet in dryer.
If connecting to existing vent, make sure vent is clean. Dryer vent must
fit inside dryer exhaust outlet and exhaust hood. Check that vent is
secured to exhaust hood with a 4" (102 mm) clamp.
