Determine vent length.
The maximum length of the exhaust system depends upon:
The type of vent (rigid metal or flexible metal).
The number of elbows used.
Type of hood.
hood styles are shown here.
1, Louvered hood style
2. Box hood style
The angled hood style (shown following) is acceptable.
See the exhaust vent length chart that matches your hood
type for the maximum vent lengths you can use.
Exhaust systems longer than specified will:
Shorten the life of the dryer.
resulting in longer drying times and
increased energy usage.
Determine the number of elbows you will need.
IMPORTANT: Do not use vent runs longer than those
in the Vent Length Chart.
The following Vent Length Chart helps you determine your
maximum vent length based on the number of 90 ° turns or
elbows you will need and the type of vent (rigid metal or
flexible metal) and hood that you will use.
Vent Length Chart
Type of Vent
90 ° turns
34 ft (12.2 m)
29 ft (10.7 m)
21 ft (7.6 m)
24 ft (9.7 m)
20 ft (8.2 m)
15 ft (6.4 m)
10 ft (4.9 m)
14 ft (7.3 m)
12 ft (5.8 m)
7 ft (4.6 m)
2 ft (3.0 m)
NOTE: Side exhaust adds a 90 ° turn inside the laundry center. To
determine maximum exhaust length, add 1 90 ° turn to the chart.
1. (Optional) Put on safety glasses and gloves.
Install exhaust hood. Use caulking compound
to seal exterior
wall opening around exhaust hood.
3. Connect vent to exhaust hood. Vent must fit inside exhaust
hood. Secure vent to exhaust hood with 4 in. (10.2 cm)
Run vent to dryer location. Use the straightest path possible
(see "Determine Vent Length"). Avoid 90 ° turns. Use duct
tape to seal all joints.
Properly leveling your laundry center prevents excessive noise
1. Check the levelness of the laundry center by placing a level
on the top edge of the washer, first side-to-side,
If the laundry center is not level, prop up the front with a
wood block and adjust the feet up or down as necessary.
Remove wood block and lower laundry center. Repeat this
step until the laundry center is level.
1. Using a 4 in. (10.2 cm) clamp, connect vent to exhaust outlet
in laundry center. If connecting to existing vent, make sure
the vent is clean. The vent must fit over the exhaust outlet
and inside the exhaust hood. Make sure the vent is secured
to exhaust hood with a 4 in. (10.2 cm) clamp.
Move laundry center into final position. Do not crush or kink
vent. Make sure laundry center is level.
