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.
Fig. 12 Duct configurations
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 that matches your hood type for the maximum
duct
lengths you can use. Do not use duct runs longer than specified
in the exhaust duct length
charts (refer to page 15).
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.

In the column
listing the type of metal duct you are using (rigid or thick wall flexible
metal), find
the maximum
length of metal duct on the same line as the number of elbows/bends
to be used
(refer to page 15),
