Exhaust System

IMPORTANT: Keep exhaust duct as short as
possible.

NOTE: Be certain old ducts are cleaned before
installing your new unit.

For best drying results, recommended maximum
length of exhaust system is shown in Table 2.

To prevent backdraft when dryer is not in operation,
outer end of exhaust pipe must have a weather hood
with hinged dampers (obtain locally).

NOTE: Weather hood should be installed at least
12 inches (30.5 cm) above the ground. Larger
clearances may be necessary for installations where
heavy snowfall can occur.
