Exhaust ducting and
connections
A gap of 3/8" (10 mm) must be
provided between the appliance
and the floor. This gap is necessary
for proper air flow and must not be
blocked by a toe-kick or thick piled
carpets.
Sufficient venting of the installation
site is essential for proper dryer
operation. Inadequate ventilation will
increase energy use and drying
times.
Do not install the dryer next to a
refrigerator. The heat emanating
from the dryer can affect the
thermostat of the refrigerator,
causing it to run continuously.
,WARNING
Danger of toxic fumes.
The exhaust gases from the dryer
must only be vented outside the
building.
DO NOT terminate the exhaust
ducts in a chimney, fireplace
ducting, a combustion appliance
vent flue, or enclosed,
unventilated area such as attics,
garages, crawlspaces, walls,
ceilings or concealed space of a
building.
To reduce the risk of fire, only use
metal ductwork.
Ducting

How to calculate the effective
duct length
The overall duct length will determine
the duct diameter (see the "Additional
duct lengths" table). In Canada the
exhaust duct must be 4" (102 mm) in
diameter.
^Measure the actual duct length
needed to go from the dryer’s
exhaust connection to the vent outlet:
1. Establish the number of elbows or
bends necessary, noting the type of
bend, angle and radius involved
(see the "Additional duct lengths"
table).
2. Add the additional duct length (as
derived by using the values
specified in the "Additional duct
lengths" table) to the actual duct
length to get the effective length.
Note:
Maximum effective duct lengths:
4" (100 mm) diameter 66 ft (20 m)
5" (125 mm) diameter 115 ft (35 m)
6" (150 mm) diameter 108 ft (33 m)
* For rigid ducting only!
Local building codes may vary.
When flexible metal duct (transition
duct) is permissible by local building
codes, the total length must not
exceed 7' 10" (2.4 m).
See the "Additional duct lengths"
table for more information on
maximum duct lengths and number
of bends.
Effective duct lengths over 66 ft (20 m)
require a larger duct diameter.
Longer ducts may lead to decreases in
dryer efficiency if the next larger duct
diameter is not followed.
Ducting

Tips about the ductwork
–Check with your local building code
to determine the maximum allowable
duct length.
–Only use rigid or flexible metal duct
for exhausting. Non-metallic flexible
hose should not be used, it is a
potential fire hazard.
–Rigid metal or flexible aluminum
ducting is preferred. Flexible foil
ducting may move and bounce due
to the high airflow of the dryer. This
could lead to a thumping or grinding
noise.
– Non-metallic flexible hose should not
be used. It is a potential fire hazard.
– In the United Stated foil-type flexible
ducts should only be used if
identified for use by the manufacturer
as compliant with the Outline for
Clothes Dryer Transition Duct,
Subject ANSI/UL 2158A.
In Canada, only flexible metal
(foil-type) ducts specifically identified
for use by the manufacturer should
be used.
–For best drying results avoid extra
long ducting with too many bends,
angles or tight corners.
–Do not assemble the duct with
screws or other fastening devices
that extend into the duct and catch
lint.
–The shorter the exhaust ductwork,
the more efficient the dryer will be.
Expelled air is slowed down in the
ducts due to friction against the inner
walls. The shorter and smoother the
inner walls are, the less friction will
be created.
–An elbow or bend creates more
friction than a straight duct. An
additional duct length factor must be
added for each elbow or bend (see
Table). This factor expresses the
resistance of the bend in terms of a
straight length of duct.
The additional length factor is then
added to the existing duct to give the
effective duct length.
A larger duct diameter helps to
reduce friction. Therefore duct
diameter should be increased if
longer duct lengths are required.
