Alternate installations for close clearances
Venting systems come in many varieties. Select the type best for
your installation. Two close-clearance installations are shown.
Refer to the manufacturer’s instructions.
NOTE:
The following kits for close clearance alternate
installations are available for purchase. Please see the
“Assistance or Service” section of this manual to order.

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 the 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 and bottom exhaust installations have a 90º turn
inside the dryer. To determine maximum exhaust length, add one
90º turn to the chart.
