2. 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.
Recommended hood styles are shown here.
2
(10,2 cm)
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.
• Reduce performance, resulting in longer drying times and
increased energy usage.
3. Determine the number of elbows you will need.
NOTE: Do not use vent runs longer than specified in the Vent
Length Char[,
The chart below 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 or flexible metal) and hood
that you will use.

Flexible metal 25 ft (7.6 m) 17 ft (5.2 m)
4 Rigid metal 27 ft (8.2 m) 21 ft (6.4 m)
Flexible metal 23 ft (7 m) 15 ft (4.6 m)
NOTE: Side and bottom exhaust installations have a 90° turn
inside the dryer. To determine maximum exhaust length, add 1
90° turn to the chart.
1. (Optional) Put on safety glasses and gloves.
2. 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)
clamp,
4. Run vent to dryer location. Use the straightest path possible.
See "Determine Vent Length," Avoid 90° turns. Use clamps to
seal all joints. Do not use duct tape, screws or other fastening
devices that extend into the interior of the vent to secure
vent.
1o To protect the floor, use a large flat piece of cardboard from
the dryer carton, Place cardboard under the entire back edge
of the dryer, See illustration,
2. Firmly grasp the body of the dryer (not the top or console
panel).
\ \
Gently lay the dryer on the cardboard.
