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, Excessivelint 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 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
allow combustible
materials
not
(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 el bows 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
swstem, 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 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 ofthe 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)
Toexhaust 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 4Y, inches (11.43 cm) away from
the wall (flush to wall exhausting may be done by going
below the dryer then sideways).
An exhaust hood positioned to line up with the dryer exhaust
can be installed directly through the outside wall, ]o 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,
