Vent System Requirements - Whirlpool KPED890T0 Instructions D'installation Et Guide D'utilisation Et D'entretien

Vent system
requirements
Venting system must terminate
to the outside.
Do not terminate the vent system
in an attic or other enclosed area.
Do not use 4" (10.2 cm) laundry-
type wall caps
Do not use plastic or metal foil
vent.
Vent work needed for installation
is not supplied.
Wall cap is Not provided with
interior-mounted motor.
Determine which venting method
to use. Vent system can extend
through either the wall or roof.
The length of vent system and
number of elbows should be kept
to a minimum to provide efficient
performance.
The size of the vent should be
uniform.
Do Not install two elbows
together.
Use duct tape to seal all joints in
the vent system.
Use caulking tape to seal the
exterior wall or floor opening
around cap.
Do Not cut joist or stud. If vent
cutout falls over a joist or stud, a
supporting frame must be
constructed.
Flexible metal vent is Not
recommended. If it is used,
calculate each foot of flexible vent
as two feet of rigid metal vent.
Flexible elbows count twice as
much as standard elbows.
NOTE: Make sure there is proper
clearance within the wall or floor
before making exhaust vent
cutouts.
Recommended vent system
length
For either interior-mounted or
exterior-mounted blower
installations, vent system length
should not exceed the maximum
lengths listed in the "Maximum
length of vent system" chart. (See
this page for Interior-mounted
vent motor; page 9 for exterior-
mounted vent motor.)

For best performance, use no more
than three 90° elbows. If more than
one elbow is used, make sure that
there is a minimum of 24" (61 cm) of
straight vent between any two
elbows. Do Not install two elbows
together. It is recommended that
you use round vent instead of
rectangular vent, especially if
elbows are required. If rectangular
vent is required, it should be
transitioned to 6" (15.2 cm) round
vent as soon as possible.
Determining the length of
system you need:
To calculate the length of system
you need, add the equivalent feet
for each vent piece that will be
needed. See example for 6"
(15.2 cm) round vent system.
