Installation Requirements
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 backpressure MUST NOT
be higher than 0.6 inches of water
column. If the system back pressure
is less than 0.6 inches of water
column, the system is acceptable.
If the manometer reading is higher
than 0.6 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 condensa-
tion 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.
Exhaust direction
The laundry center may be exhausted four
(4) ways with rear flush installation:
1. Straight back
2. Down (8 inch [20.3 cm] length of 4
inch diameter [102 mm] rigid duct and
1 elbow down)
3. Left (8 inch [20.3 cm] length of 4 inch
diameter [102 mm] rigid duct, 1 elbow
down and 1 elbow left)
4. Right (8 inch [20.3 cm] length of 4
inch diameter [102 mm] rigid duct, 1
elbow down and 1 elbow right)
An exhaust hood positioned to line up with
the dryer exhaust can be installed directly
through the outside wall. To exhaust to
the side or down, add an 8 inch (20.3
cm) length of standard 4 inch (102 mm)
diameter duct and a 90° elbow.
To exhaust up, add an 11 inch (28 cm)
length of standard 4 inch (102 mm)
diameter duct and a 90° elbow. The unit
will be positioned about 4.5 inches (11.5
cm) away from the wall (flush to wall
exhausting may be done by going below
the dryer then sideways).
