q Check and clean the exhaust duct system and exhaust hood at least once each year, and any time you suspect dryer performance is decreased. Remove accumulated lint to prevent diminished air flow or clogging of the system. Professional cleaning is recommended annually and when attaching your dryer to a previously used exhaust duct system. q Replace any plastic or metal foil venting sections with rigid metal or flexible metal ducting. Rigid metal ducting is recommended. i Correct exhaust system installation is the responsibility of the consumer. Problems that result from incorrect installation are not covered by the appliance warranty. Exhaust ducting which is longer than specified in the maximum ductwork length table on page 12 is not permitted. Not adhering to this table will extend drying time, cause lint to accumulate and affect dryer performance and dryer lifeĆtime. 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 rigid duct and for rigid duct used with flexible metal duct is shown in the table below. If using flexible metal ducting to connect the appliance to the ductwork system, the total length of flexible metal duct used shall not exceed 2.4 m and can only be used to connect the dryer to the ductwork system. As the table below shows, the maximum overall ductwork length is reduced if flexible ducting is used. Maximum Ductwork Length Number of Rigid Duct 90° Turns or Elbows Flexible Duct in Combination with Rigid Duct 0 66 ft. 45 ft. (2011 cm) (1372 cm) 1 56 ft. 36 ft. (1707 cm) (1097 cm) 2 48 ft. 29 ft. (1463 cm) (884 cm) 3 39 ft. 22 ft. (1189 cm) (671 cm) 4 30 ft. (914 cm) 16 ft. (488 cm) Note: Side and bottom exhaust installations have a 90° turn inside the dryer. Take this into account when using the table above. 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. 12

Exhaust
ducting
which
is
longer
than
specified
in
the
maximum
ductwork
length
table
on
page
12
is
not
permitted.
Not
adhering
to
this
table
will
extend
drying
time,
cause
lint
to
accumulate
and
affect

All
joints
should
be
tight
to

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
rigid
duct
and
for
rigid
duct
used
with
