Determine vent path
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.
When using elbows or making turns, allow as much room as
possible.
Bend vent gradually to avoid kinking.
Use the fewest 90° turns possible.
Determine vent length and elbows needed for best
drying performance
Use the following Vent system chart to determine type of vent
material and hood combinations acceptable to use.
NOTE: Do not use vent runs longer than those specified in
the Vent system chart. Exhaust systems longer than those
specified will:
Shorten the life of the dryer.
Reduce performance, resulting in longer drying times and
increased energy usage.
The Vent system chart provides venting requirements that will
help to achieve the best drying performance.
Vent system chart
NOTE: Performance of rear exhaust to either side of the dryer is
equivalent to adding one elbow. To determine maximum exhaust
length, add one elbow to the chart.

Install Vent System
1. Install exhaust hood. Use caulking compound to seal exterior
wall opening around exhaust hood.
2. Connect vent to exhaust hood. Vent must fit inside exhaust
hood. Secure vent to exhaust hood with 4" (10.2 cm) clamp.
3. Run vent to dryer location. Use the straightest path possible.
See “Determine vent path” in “Plan Vent System.” Avoid 90º
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.
