Installation Requirements
Exhaust system requirements, continued
Install male fi ttings in correct direction:
CORRECT
In installations where the exhaust system has not described
in the previous pages, 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 1.0 inches of water column. If the system back
pressure is less than 1.0 inches of water column, the
system is acceptable. If the manometer reading is
higher than 1.0 inches of water column, the system is
too restrictive and the installation is unacceptable.
Although vertical orientation of the exhaust system is
acceptable, the performance of this dryer could be
adversely aff ected by the following conditions:
•
The use of non-rigid metal duct work.
•
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.
•
Accelerated accumulation of lint buildup in dryer
exhaust system, 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.

Exhaust direction
Directional exhausting can be accomplished by installing
a quick-turn 90° dryer vent elbow directly to the exhaust
outlet of dryer. Dryer vent elbows are available through
your local parts distributor or hardware store.
See also Clearance Requirements on the next page.
NOTE
Use of 90° quick-turn elbow
is required to meet minimum
installation depth of free-
standing dryer.
