- Bottom air exhaust
A qualified technician should
change the exhaust air outlet to the
optional connection location.
Ductwork
To ensure optimum performance,
the ducting system of the dryer
should be as short as possible with
a minimum number of elbows.
Your dryer will work best when the
venting system has as few air flow
restrictions as possible. Exhaust
ducting which is longer than
recommended may extend drying
time, cause lint to accumulate and
affect dryer performance and dryer
life.
FourĆinch (approx. 100 mm)
diameter ducting should be used.
Use either rigid metal or flexible
metal ducting material. DO NOT
use plastic or nonĆmetal duct with
this dryer.
DO NOT assemble the ductwork
with screws or fasteners that
extend into the duct. They will serve
as an accumulation point for lint.
Joints should be secured with
aluminium tape.
All joints should be tight to avoid
leaks. The male end of each duct
section must point away from the
dryer.
Whether connecting to an existing
venting system or a new venting
system, make sure that all ducting
is clean and free of lint.
The maximum permitted length for
both rigid and flexible metal duct is
shown in the table below.

Note:
Side and bottom exhaust
installations have a 90° turn inside
the dryer. To determine maximum
exhaust length, add one 90° turn to
the chart.
More than two 90 ° turns are not
recommended. For best
performance, separate all turns by
at least 4 ft. of straight duct,
including distance between last turn
and exhaust hood.
Exhaust vent hood
The exhaust duct must end with an
approved exhaust vent hood with
swing out damper(s). DO NOT
use
an exhaust vent hood with
magnetic latches.
To avoid exhaust restriction, the
outlet must be a minimum of
12 inches (30 cm) above ground
level or any other obstructing
surface.
Required parts
The parts required for the exhaust
air system (elbows, lines, exhaust
air outlets) are not included in
standard delivery of the dryer.
