All joints should be tight to avoid air leaks. The male end of each section of
ducting must point away from the dryer.
Use clamps or duct tape to connect and seal all joints.
Do not connect with screws or other fasteners that
extend into the interior of the duct as they will create a
collection point for lint.
Avoid running the exhaust system through an unheated area as this will cause
condensation to form inside the duct and increase the rate of lint accumulation.
Avoid running the exhaust system vertically through a roof as this may expose
the exhaust system to down drafts, causing an increase in air restriction.
Avoid sagging, compression or crimping of the exhaust system as this will result
in reduced air ow and poor dryer performance.
Do not screen the end of the exhaust system. Lint will accumulate and
eventually clog the screen. Use an approved exhaust hood to terminate the duct
outdoors.
The total length of exible metal duct shall not exceed 2.4 m (7.8 ft).
EXHAUST HOOD
Use an approved exhaust hood with a swing-out damper that opens when the
dryer is in operation. When the dryer stops, the damper automatically closes to
prevent drafts and the entrance of insects and rodents.
Louvered or box hood styles are recommended. Angled hood styles are
acceptable, but should be used only for short run installations. See the
“Recommended Maximum Exhaust Length” chart for more information.
To avoid restricting air ow, maintain a minimum of 12” (30.5 cm) clearance
between the vent hood and the ground or any other obstruction.
