Venting Requirements
Height & Clearance
•
Vent system must evacuate to the
exterior
–
Outside (through the
roof or side wall).
•
DO NOT terminate the vent system in
an attic or other enclosed area.
•
Use rigid metal/aluminum vent only.
•
NEVER use plastic vent or plastic vent cover.
•
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/cooking element.
3.
Distance between the range hood
and
the
countertop/cooking
element which is recommended
at 28” to
30’’.
4.
Height of hood and duct cover
with the cabinet
.
For the most efficient & quiet operation:
•
It is recommended that the range
hood be vented vertically through the
roof through 6” (15.3 cm) round
metal/aluminum vent or vented
horizontally through the wall through
a rectangular vent measuring 3 ¼’’ x
10’’.
•
The size of the vent should be uniform.
•
If venting vertically, do not use more
than three 90° elbows. Do not install
two elbows together.
•
Make sure there is a minimum of 24”
(61 cm) of straight vent between the
elbows if more than one elbow is
used.
•
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,
DO
NOT
use damper (which is supplied)
on top of the range hood

•
Use duct tape to seal all joints in the
vent system.

Use caulking to seal the exterior wall
or roof opening around the cap.
