Exhausting
Choose a route that will provide the straightest and most direct path outdoors. Planthe
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:
a The type of ducts (rigid or thick walled flexible metal).
The number of elbows or bends used.
1 Refer to the exhaust duct length chart for the maximum duct lengths you carl use. Do not use
duct runs longer than specified in the exhaust duct length charts (refer to next page).
Exhaustduct systems longer than specified will:
Accumulate lint creating a potential fire hazard.
Shorter] the life of the dryer.
Reduce performance, resulting in longer drying times and an increased energy usage.
;2Determine the number of elbows/bends you will need.
:3In the following table, find the maximum length of rigid metal duct or] the same line as the
number of elbows/bends to be used (refer to next page).
4 The total length of flexible metal duct shall not exceed 2.4m (8 ft).
