INSTALLATION REQUIREMENTS (Cont.)
See also Clearance Requirements on the next page.
Exhaust direction
Directional exhausting can be accomplished by installing a
quick-turn 90° dryer vent elbow directly to exhaust outlet
of dryer. Dryer vent elbows are available through your local
parts distributor or hardware store.
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 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 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 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.
