Exhaust airflow

Maximum length of the exhaust system depends upon the type of vent used, number of elbows, and the type of exhaust hood. The maximum length for both heavy and flexible metal vent is shown in the chart following.

See figure 1 for exhaust outlet location (at rear of the dryer) and dimensions. Minimum side and rear clearances appear on model and rating plate on back of dryer.

FIGURE 1

Determining vent length

The maximum length of the exhaust system depends upon:

•The type of vent (heavy or flexible metal).

•The number of elbows (90° turns) used.

To determine maximum vent length:

1.See the Exhaust Hood Type 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 chart, Exhaust systems longer than specified will:

•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 (heavy or flexible), find the maximum length of metal vent on the same line as the number of elbows.
