Part 8 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.
Exhaust Requirements and Instructions:
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. The exhaust duct must be four inches (10.2 cm) in
diameter with no obstructions. The exhaust duct
should be kept as short as possible. Make sure to
clean any old ducts before installing your new dryer.
3. Rigid or semi-rigid metal ducting is recommended
for use as transition ducting between the dryer and
and the wall. In special installations when it is
impossible to make a connection with the above
recommendations, then a UL-listed flexible metal
transition duct may be used between the dryer and
wall connection only. The use of this ducting will
affect dry time.
4. DO NOT use sheet metal screws on exhaust pipe
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.
5. To maximize operating results, please observe the
duct length limitations noted in the chart above.
