Plan the exhaust vent
installation
Route the vent
The exhaust outlet is located at the
centre of the rear of the dryer.
The exhaust vent can be routed up
down, left, right or straight out the
back of the dryer.
The design of the flue system should
ensure that any condensate formed
when operating the appliance from
cold, is either retained and
subsequently evaporated or
discharged. Following these
installation instructions should
adequately meet this requirement.
Select the route that will provide the
straightest and most direct path
outdoors. Plan the installation to use
the fewest number of elbows and
turns. Avoid making 90° turns.

When using elbows or making
turns, allow as much room as
possible. Bend vent gradually to avoid
kinking.

The maximum length of the exhaust
system depends upon:
• the type of vent (rigid or flexible
metal).
• the number of elbows used.
1. See the exhaust vent length chart
that matches your type hood for the
maximum vent lengths you can use.
Do not use vent runs longer than
specified in exhaust vent length
charts.
Exhaust Systems longer than specified
10.2 cm
will:
(4")
– Accumulate lint creating a potential
fire hazard.
– Shorten the life of the dryer.
– Reduce performance, resulting in
Flexible longer drying times and increased
(fully extended)
energy usage.

will need.
6.1 m (20 ft.)
5.5 m (18 ft.)
3. In the column listing the type of
metal vent you are using (rigid or
flexible), find the maximum length of
metal vent on the same line as the
number of elbows.
6.4 cm
(2-1/2")
The maximum length using a
5.1 cm x 15.2 cm (2" x 6")
rectangular vent with 2 elbows and
a 6.4 cm (2-1/2") exhaust hood is
2.4 m (8 ft.).
