Route the vent
The exhaust outlet is located at the
center of the rear of the dryer.
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.
This dryer may be converted to exhaust
out the right or left side or through the bottom.
Typical installations

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.

The maximum length of the exhaust
system depends upon:
• the type of vent (rigid or flexible
metal).
• the number of elbows used.
• side or bottom exhaust. Side or
bottom exhaust adds a 90° turn
inside the dryer. To determine
maximum exhaust length, add one
90° turn to the chart.
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
4"
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
Flexible
metal vent on the same line as the
(fully extended)
number of elbows.

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
