Exhaust system requirements, continued
- FIRE HAZARD - A clothes dryer must be
exhausted outdoors. Do not exhaust dryer into a chimney, a
wall, a ceiling, an attic, a crawl space or any concealed space
of a building. A clothes dryer produces combustible lint. If
the dryer is not exhausted outdoors, some fi ne lint will be
expelled into the laundry area. An accumulation of lint in any
area of the home can create a health and fi re hazard.
The dryer must be connected to an exhaust outdoors.
Regularly inspect the outdoor exhaust opening and remove
any accumulation of lint around the outdoor exhaust opening
and in the surrounding area.
- FIRE HAZARD -
Do not allow combustible materials (for example: clothing,
draperies/curtains, paper) to come in contact with exhaust
system. The dryer MUST NOT be exhausted into a chim-
ney, a wall, a ceiling, or any concealed space of a building
which can accumulate lint, resulting in a fi re hazard.
Do not screen the exhaust ends of the vent system, or use
any screws, rivets or other fasteners that extend into the
duct to assemble the exhaust system. Lint can become
caught in the screen, on the screws or rivets, clogging the
duct work and creating a fi re 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 fi ttings MUST be installed downstream with the
fl ow of air.
- FIRE HAZARD - Exceeding the length of
duct pipe or number of elbows allowed in the "MAXIMUM
LENGTH" charts can cause an accumulation of lint in the ex-
haust system. Plugging the system could create a fi re hazard,
as well as increase drying times.

CORRECT
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 fl uff (cool
down) and start the dryer.
3. Read the measurement on the manometer.
4. The system back pressure MUST NOT be 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 .075
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 vertically 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.
