Installation
IMPORTANT:
• Vent system must terminate to the outside (roof or side wall).
• DO
NOT terminate the vent system in an attic or other
enclosed area.
• DO
NOT
use
4”
(10.2
cm)
laundry-type
wall
caps.
• Use
metal/aluminum
vent
only.
A
rigid
metal/aluminum
vent is recommended.
• DO
NOT
use
a
plastic
vent.
• Always
keep
the
duct
clean
to
ensure
proper
airflow.
• Calculate
the
following
figures
before
installation:
1. Distance from the floor to the ceiling
2. Distance between the floor and the countertop/stove
3. A distance of 24” to 30” is recommended between
stove top and the bottom of range hood. 30” minimum
is required for gas stove tops.
4. Height of hood and duct cover.
For the most efficient
and
quiet operation:
• It
is
recommended
that
the
range
hood
be
vented
vertically through the roof through 6” (15.3 cm) or
bigger round metal/aluminum vent work.
• The
size
of
the
vent
should
be
uniform.
• Use
no
more
than
three
90°
elbows.
• Make sure there is a minimum of 24” (61 cm) of
straight vent between the elbows if more than one
elbow is used.
• DO
NOT
install
two
elbows
together.
• The length of vent system and number of elbows should be
kept to a minimum to provide efficient performance.
• The
vent
system
must
have
a
damper.
If
roof
or
wall
cap has a damper, you may remove damper flaps from
damper to increase air flow.
• Use silver tape or duct tape to seal all joints in the
vent system.
• Use caulking to seal exterior wall or roof opening
around the cap.
• Only one flange is needed in the air duct system,
either on top of the motor (provided) or outside.
