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, aswell 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 sealall 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. MAXIMUM LENGTH of 4" (10.2 cm) Dia.

Although vertical orientation of the exhaust system is acceptable, certain extenuating circumstances could affect the performance of the dryer: • Only the rigid metal duct work should be used. Venting vertical through a roof may expose the exhaust system to down drafts causing an increase in vent restriction.

NOT RECOMMENDED
INSTALL MALE FITTINGS IN
CORRECT
DIRECTION
In installations where the exhaust system is not described in the
charts, the following
method must be used to determine if the
exhaust system is acceptable:
1.
Connect
an inclined or digital manometer between the
dryer and the point the exhaust connects to the dryer.
2.
Set the dryer timer and temperature to air fluff (cool down)
and start the dryer.
3.
Read the measurement on the manometer.
4.
The system back pressure
MUSTNOTbe
higher than 0.75
inches of water column.
If the system back pressure is less
than 0.75 inches of water column, the system is acceptable.
If the manometer reading is higher than 0.75 inches of water
column, the system is too restrictive and the installation
is
unacceptable.
Although vertical orientation of the exhaust system is acceptable,
certain extenuating circumstances could affect the performance
of the dryer:
Only the rigid metal duct work should be used.
Venting vertical through a roof may expose the exhaust system
to down drafts causing an increase in vent restriction.
Running the exhaust system through an uninsulated area may
cause condensation and faster accumulation
of lint.
Compression
or crimping of the exhaust system will cause an
increase in vent restriction.
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.
