Location Requirements; Venting Requirements - Maytag MDE17MN Installation Instructions Manual

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.
[] 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).
[] The dryer vent must not be discharged into a flue which is
used for exhausting fumes from appliances burning gas or
other fuels, chimney, wall, ceiling, or a concealed space of
a building, or any other vent used for venting.
[] Do not use an exhaust hood with a magnetic latch.
[] Do not install flexible metal vent in enclosed walls, ceilings,
or floors.
[] 102 mm (4") heavy metal vent and clamps must 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. Do not use duct tape.
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 to avoid crushing
and kinking.
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.
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, or bushes).
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.
Exhaust A ir Flow
A. Good
B. Better
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.
Multiple Dryer Venting
[] A main vent can be used for venting a group of dryers. Main
vent should be sized to remove 5663 I/min (200 CFM) of air
per dryer. Large-capacity lint screens of proper design may be
used in the main vent if checked and cleaned frequently. The
room where the dryers are located should have make-up air
equal to or greater than the airflow of all the dryers in the
room.
[] A back-draft damper kit is needed and is available from a
commercial laundry distributor; it should be installed in the
vent of each dryer to keep exhausted air from returning into
the dryers and to keep the exhaust in balance within the
main vent. Unobstructed return air openings are required.
