NOTE:
Maximum duct length of 60 feet is allowed.
Subtract 4 feet of duct for each 90° elbow.
If more than 20 feet of duct is needed, the
diameter must be increased to 6” or 8” (152
mm or 203 mm).
NOTE:
When installing in warm climates (77° F
and above) with high humidity levels, do not
route the air exhaust duct upwards.
To connect the exhaust duct to a
ventilation outlet, follow the steps
below:
1.Connect the exhaust duct to a ventilation
exhaust fitting or to a discharge through
the wall.
2.Secure the duct joint to the outlet stub on
the machine.
3.Run the duct with as few bends as pos-
sible to the point of discharge.
WARNING!
This appliance should not be exhausted
into a chimney, a wall, a ceiling, or a con-
cealed space of a building. Only a metal
ventilation grill should be used.
If the duct is taken to a wall outlet, a ventila-
tion grill should be fitted to prevent reverse
flow of cold air. Fit the ventilation grill to the
outside or inside of the wall.
