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 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 fire hazard, as well as increase drying
times.
Do not screen the exhaust ends of the vent
system, nor use any screws, rivets or other fastening means
that extend into the duct and catch lint to assemble the
exhaust system. Lint can become caught in the screen, on the
screws or rivets, clogging the duct work and creating a fire hazard
as well as increasing drying times. Use an approved vent hood
to terminate the duct outdoors, and seal all joints with duct
tape. All male duct pipe fittings MUST be installed downstream
with the flow of air.
Explosion hazard. Do not install the dryer
where gasoline or other flammables are kept or stored. If
the dryer is installed in a garage, it must be a minimum of 18
inches (45.7 cm) above the floor. Failure to do so can result in
death, explosion, fire or burns. The exhaust system back pressure
MUST not exceed 0.6 inches (1.52 cm) of water column,
measured with an inclined manometer at the point the exhaust
connects to the dryer. The exhaust system should be inspected
and cleaned a minimum of every 18 months with normal
usage. The more the dryer is used, the more often you should
check the exhaust system and vent hood for proper operation.
The maximum length of the exhaust system depends upon the
type of duct used, number of elbows and type of exhaust hood.
The maximum length for both rigid and flexible duct is shown in
the chart below.
