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.
Do not use plastic flexible duct to exhaust
the dryer. Excessive lint can build up inside the exhaust
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 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.
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.
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.
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 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.
The laundry center may be exhausted four (4) ways with
rear
flush
installation:
1.
Straight back
2.
Down
(8 inch [20.32 cm] length of 4 inch [10.16 cm]
rigid duct and 1 elbow down)
3.
Left
(8 inch [20.32 cm] length of 4 inch [10.16 cm]
rigid duct, 1 elbow down and 1 elbow left)
4.
Right
(8 inch [20.32 cm] length of 4 inch [10.16 cm]
rigid duct, 1 elbow down and 1 elbow right)
To exhaust up, add an 11 inch (27.94 cm) length of
standard 4 inch (10.16 cm) diameter duct and a 90°
elbow. The unit will be positioned about 4½
inches (11.43
cm) away from the wall (flush to wall exhausting may be
done by going below the dryer then sideways).
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.

An exhaust hood positioned to line up with the dryer
exhaust can be installed directly through the outside wall.
To exhaust to the side or down, add an 8 inch (20.32 cm)
length of standard 4 inch (10.16 cm) diameter duct and a
90° elbow.
