Exhaust System Requirements - Kenmore 27” (69 cm) Installation Instructions Manual

EXHAUST SYSTEM REQUIREMENTS

Use only 4 inch (10.16 cm) diameter (minimum) rigid or
flexible metal duct and approved vent hood which has a
swing-out damper(s) that opens when the dryer is in
operation. When the dryer stops, the damper(s)
automatically closes to prevent drafts and the entrance
of insects and rodents. To avoid restricting the outlet,
maintain a minimum of 12 inches (38.5 cm) clearance
between the vent hood and the ground or any other
obstruction.
WARNING
The following are specific requirements for
proper and safe operation of your laundry center. Failure to
follow these instructions can create excessive drying times
and fire hazards.
WARNING
Do not use plastic flexible
exhaust the dryer. Excessive lint can build up inside the
system and create a fire hazard and restrict air flow. Restricted
air flow will increase drying times. If your present system is
made up of plastic duct or metal foil duct, replace it with a rigid
or flexible metal duct. Ensure the present duct is free of any
lint prior to installing laundry center dryer duct.

WARNING
If the dryer is not exhausted outdoors, some
fine lint will be expelled into the laundry area. An accumulation
of lint in any area of the home can create a health and fire
hazard. The dryer exhaust system MUST be exhausted to
the outside of the dwelling!

WARNING
Do not allow combustible materials (for
example: clothing,draperies/curtains, paper) to come in contact
with the 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.
WARNING
Do not exceed the length of duct pipe or
number of elbows allowed in the" EXHAUST DUCT LENGTHS"
chart. Lint can accumulate in the system, plugging the system
and creating a fire hazard, as well as increasing drying times.
WARNING
Do not screen the exhaust ends of the vent
system, nor use any screws or rivets to assemble the exhaust
system. Lint can become caught in the screen, on the screws or
rivets, clogging the exhaust system 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.
WARNING
Explosion hazard. Do not install the laundry
center where gasoline or other flammables are kept or stored.If
the laundry center 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 two years 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.
