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 Length
1.
Select the route that will provide the straightest and most
direct path outdoors. Plan the installation to use the fewest
number of elbows and turns. When using elbows or making
turns, allow as much room as possible. Bend vent gradually to
avoid kinking. Avoid 90º turns.
2.
Determine vent length.
The maximum length of the exhaust system depends upon:
■
The type of vent (rigid metal or flexible metal).
■
The number of elbows used.
■
Type of hood.
Recommended hood styles are shown here.
The angled hood style (shown following) is acceptable.
See the exhaust vent length chart that matches your hood
type for the maximum vent lengths you can use.
Exhaust systems longer than specified will:
■
Shorten the life of the dryer.
■
Reduce performance, resulting in longer drying times and
increased energy usage.
3.
Determine the number of elbows you will need.
IMPORTANT:
Do not use vent runs longer than those
specified in Vent Length Chart.
The following chart helps you determine your maximum vent
length based on the number of 90° turns or elbows you will
need and the type of vent (rigid or flexible metal) and hood
that you will use.
Vent Length Chart
NOTE:
Side exhaust adds a 90° turn inside the washer/dryer. To
determine maximum exhaust length, add one 90° turn to the
chart.
Install Vent System
1.
(Optional) Put on safety glasses and gloves.
2.
Install exhaust hood. Use caulking compound to seal exterior
wall opening around exhaust hood.
3.
Connect vent to exhaust hood. Vent must fit inside exhaust
hood. Secure vent to exhaust hood with 4 in. (10.2 cm) clamp.
4.
Run vent to dryer location. Use the straightest path possible.
See “Determine Vent Length.” Avoid 90º turns. Use clamps to
seal all joints. Do not use duct tape, screws or other fastening
devices that extend into the interior of the vent to secure vent.
Level Washer/Dryer
Properly leveling your washer/dryer prevents excessive noise and
vibration.
1.
Check the levelness of the washer/dryer by placing a level on
the top edge of the washer, first side to side, then front to
back.
