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.
If a combination of rigid and flexible metal vent is used.
Recommended hood styles are shown here.
1. Louvered hood style
2. Box hood style
The angled hood style (shown following) is acceptable.
The same length of vent can be used with any of the 3 exhaust
hoods shown.
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.
NOTE:
Do not use vent runs longer than specified in the Vent
Length Chart.
When using only one type
of metal vent:
Use the following chart to help you determine your maximum
vent length based on the number of 90° turns or elbows you
will need and the type of vent (rigid and/or flexible metal) you
will use.
When using a combination of rigid and flexible
metal vent:
Use the following charts to help you determine your maximum
vent length based on the number of 90° turns or elbows you
will need.
Determine the number of elbows or turns you will need.
Determine the length of the fully extended flexible metal
vent you will use. Find the column that has the nearest
number of feet to what you will be using.
Match the number of turns or elbows with the length of the
fully extended flexible metal vent you will use to find the
maximum length of rigid metal vent you can use.
