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. Avoid making 90° turns.
When using elbows or making
turns, allow as much room as
possible. Bend vent gradually to avoid
kinking.

Typical installations exhaust from the rear
of the dryer.
Plan the exhaust vent
installation
Route the vent
The exhaust vent can be routed up,
down, left, right or straight out the
back of the dryer. See “Recessed
area/closet installation” section, Page 4,
for space requirements.
Determine vent length
The maximum length of the exhaust
system depends upon:
• the type of vent (rigid or flexible
metal).
• the number of elbows used.
1. See the exhaust vent length chart
that matches your type hood for the
maximum vent lengths you can use.
Do not use vent runs longer
than specified in exhaust vent
length charts.
Exhaust 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
increased energy usage.
2. Determine the number of elbows
you will need.
3. In the column listing the type of
metal vent you are using (rigid or
flexible), find the maximum length of
metal vent on the same line as the
number of elbows.
4. Determine the number of 4-inch
diameter vent clamps required.
The maximum length using a 2" x
6" rectangular vent with 2 elbows
and a 2-1/2" exhaust hood is 8 feet.
For exhaust systems not covered
by exhaust vent length charts (such
as multiple unit hookups, plenums,
and power-assist fans), see Service
Manual, Part No. 603197. (To
purchase the Service Manual, see
your Use and Care Guide for a
toll-free telephone number.)
