Fire Hazard
Use a heavy metal vent.
Do not use a plastic vent.
Do not use a metal foil vent.
Failure to follow these instructions can result in death
or fire.
WARNING:
To reduce the risk of fire, this dryer MUST BE
EXHAUSTED OUTDOORS.
[] Following these venting requirements will minimise ducting
air noise.
[] Adequate ventilation has to be provided to avoid the backflow
of gases into the room from appliances burning other fuels,
including open fires (i.e. available airflow into the room should
match airflow out from the room).
[] Dryer exhaust must not be connected into any gas vent,
chimney, wall, ceiling, attic, crawlspace, or a concealed space
of a building. Only rigid or flexible metal vent shall be used for
exhausting.
[] Do not use an exhaust hood with a magnetic latch.
[] Do not install flexible metal vent in enclosed walls, ceilings,
or floors.
[] Only a 102 mm (4") heavy metal exhaust vent and clamps
may be used.

[] Use clamps to seat all joints. Vent must not be connected
or secured with screws or other fastening devices which
extend into the interior of the vent and catch lint. Do not use
duct tape.

improper venting can cause moisture and lint to collect
indoors, which may result in:
[] Moisture damage to woodwork, furniture, paint, wallpaper,
carpets, etc.
[] Housecleaning problems and health problems.
IMPORTANT: Observe all governing codes and ordinances.
Use a heavy metal vent. Do not use plastic or metal foil vent.
Rigid metal vent is recommended for best drying performance
and to avoid crushing and kinking.
6
Flexible metal vent must be fully extended and supported when
the dryer is in its final position. Remove excess flexible metal
vent to avoid sagging and kinking that will result in reduced
airflow and poor performance.
The total length of flexible metal vent should not exceed 2.4 m
(73/4ft.).
An exhaust hood should cap the vent to keep rodents and
insects from entering the building.
Exhaust hood must be at least 305 mm (12") from the ground
or any object that may be in the path of the exhaust (such as
flowers, rocks, bushes, or snow).
If using an existing vent system, clean lint from the entire length
of the system and make sure exhaust hood is not plugged with
lint. Replace any plastic or metal foil vent with rigid metal or
flexible metal vent.
Plan installation to use the fewest number of elbows and turns.

Allow as much room as possible when using elbows or making
turns. Bend vent gradually to avoid kinking.
Vent outlet is located at the center of the bottom dryer back.
The vent can be routed up, down, left, right, behind the dryer,
or straight out the back of the dryer.
Vent System Length
Maximum length of vent system depends upon the type of vent
used, number of elbows, and type of exhaust hood.

If dryer is installed in a confined area, such as a bedroom,
bathroom, or closet, provision must be made for enough air
for combustion and ventilation. (Check governing codes and
ordinances.) See "Recessed Area and Closet Installation
Instructions" in the "Location requirements" section.
A 102 mm (4") outlet hood is preferred. However, a 64 mm
(21/_ ' ') outlet exhaust hood may be used. A 64 mm (2W')
outlet creates greater back pressure than other hood types.
For permanent installation, a stationary vent system is required.
