INSTALLATION REQUIREMENTS
WARNING
FIRE HAZARD
A clothes dryer must be exhausted outdoors. Do not
exhaust dryer into a chimney, a wall, a ceiling, an attic,
a crawl space or any concealed space of a building. A
clothes dryer produces combustible lint. If the dryer is
not exhausted outdoors, some fi ne lint will be expelled
into the laundry area. An accumulation of lint in any
area of the home can create a health and fi re hazard.
WARNING
FIRE HAZARD
Do not allow combustible materials (for example:
•
clothing, draperies/curtains, paper) to come in
contact with exhaust system. The dryer MUST NOT
be exhausted into a chimney, a wall, a ceiling,
or any concealed space of a building which can
accumulate lint, resulting in a fi re hazard.
Do not screen the exhaust ends of the vent system,
•
or use any screws, rivets or other fasteners that
extend into the duct to assemble the exhaust
system. Lint can become caught in the screen, on
the screws or rivets, clogging the duct work and
creating a fi re hazard as well as increasing drying
times. Use an approved vent hood to terminate the
duct outdoors, and seal all joints with metal foil duct
tape. All male duct pipe fi ttings MUST be installed
downstream with the fl ow of air.
WARNING
FIRE HAZARD
Do not install fl exible plastic or fl exible foil venting
•
material.
If installing semi-rigid venting, do not exceed 8 ft.
•
(2.4 m) duct length.
WARNING
FIRE HAZARD
Exceeding the length of duct pipe or number of elbows
allowed in the “MAXIMUM LENGTH” charts can cause
an accumulation of lint in the exhaust system. Plugging
the system could create a fi re hazard, as well as
increase drying times.
