Plan the exhaust vent installation
Typical installations exhaust from the rear of the dryer.
exhaust outlet
The exhaust outlet is located at the center of the rear of the dryer.
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.

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.
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
