and for venting outside. Failure to follow these
instructions may result in fire or death.
• To reduce the risk of fire, combustion, or
accumulation of combustible gases, DO
NOT exhaust dryer air into an enclosed and
unventilated area, such as an attic, wall, ceiling,
crawl space, chimney, gas vent, or concealed

• Rigid, semi-rigid or flexible metal ducting is
recommended for use between the dryer and
the wall. All non-rigid metal transition duct

transition duct could affect drying time. Failure
to follow these instructions may result in fire or
death.
• DO NOT use sheet metal screws or other
fasteners which extend into the duct that
could catch lint and reduce the efficiency of
the exhaust system. Secure all joints with duct
tape. Failure to follow these instructions may result
in fire or death.

limitations noted in the chart. Failure to follow
these instructions may result in extended drying
times, fire or death.
