EXHAUST REQUIREMENTS AND MAINTENANCE
Following are important instructions and information concerning the exhaust requirements for your dryer.
Warning:
DO NOT exhaust dryer air into an enclosed and unventilated area, such as an attic, wall, ceiling,
crawl space, chimney, gas vent, or concealed space of a building. To reduce the risk of fire, DO NOT exhaust the
dryer with plastic or thin foil Ducting. Failure to do so can result in death, explosion, or fire.
1. Venting materials are not provided with the dryer and
you should obtain the necessary venting materials
locally. For example, the outer end of exhaust pipe
must have a weather hood with hinged dampers to
prevent back-draft when the dryer is not in use.
2. In Canada, that the exhaust duct shall be 4in. (10.2 cm)
in diameter with no obstructions. In the United States.
The required exhaust duct diameter; The exhaust duct
should be kept as short as possible. Make sure to clean
any old ducts before installing your new dryer.
3. Use only rigid or flexible metal ductwork inside the
dryer cabinet and for venting outside.
4. Rigid or semi-rigid metal ducting is recommended for
use between the dryer and the wall. In special
installations when it is impossible to make a
connection with the above recommendations, a
UL-listed flexible metal transition duct may be used
between the dryer and wall connection only. The use
of this ducting will affect drying time.
5. In Canada, that only those foil-type flexible ducts, if
any, specifically identified for use with the
appliance by the manufacturer shall be used. In the
United States, that only those foil-type flexible
ducts, if any, specifically identified for use with the
appliance by the manufacturer and that comply with
the Outline for Clothes Dryer Transition Duct,
Subject 2158A, shall be used.
6. To maximize operating results, please observe the
duct length limitations noted in the chart above.

joints or other fastening means which extend into
the duct that could catch lint and reduce the
efficiency of the exhaust system. Secure all joints
with duct tape.
