Exhausting
Choose a 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 (rigid duct) or making turns (thick wall flexible metal duct), allow as much
room as possible.
With thick wall flexible metal duct bend duct gradually to avoid kinking and
avoid 90˚ turns.
Maximum Length of Exhaust Duct
The maximum length of the exhaust duct system depends upon:
The type of ducts (rigid or thick walled flexible metal).
±
The number of elbows or bends used.
±
Refer to the exhaust duct length chart for the maximum duct lengths you can use.
Do not use
1
duct runs longer than specified in the exhaust duct length charts (refer to next page).
Exhaust duct systems longer than specified will:
Accumulate lint creating a potential fire hazard.
±
Shorten the life of the dryer.
±
Reduce performance, resulting in longer drying times and an increased energy usage.
±
Determine the number of elbows/bends you will need.
2
In the following table, find the maximum length of rigid metal duct on the same line as the
3
number of elbows/bends to be used (refer to next page).
The total length of flexible metal duct shall not exceed 2.4m (8 ft).
