Exhaust System Requirements - Frigidaire GLGH1642FS0 Instructions D'installation

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.

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.
1234546
Do not use plastic flexible duct or metal foil
to exhaust the dryer. Excessive lint can build up inside the exhaust
system and create a fire hazard and restrict air
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 the laundry center dryer duct.

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!

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.
1234546
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.
1234546
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.
Explosion hazard.
1234546
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.
