Exhaust direction
The laundry center may be exhausted four (4) ways with
rear fl ush 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) 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 0.6 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 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.

Exhaust system requirements, continued
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 (fl ush to wall exhausting may be done by going
below the dryer then sideways).
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.
