Vent system must terminate to the outside•
(roof or side wall).
DO NOT terminate the vent system in an at-•
tic or other enclosed area.
DO NOT use 4” (10.2 cm) laundry-type wall•
caps.
Use metal/aluminum vent only. Rigid metal/•
aluminum vent is recommended.
DO NOT use plastic vent.•
Always keep the duct clean to ensure proper•
airflow.
Calculate the following figures before instal-•
lation:
Distance from the floor to the ceiling.1.
Distance between the floor to the coun-2.
tertop/stove (recommend* 27” to 30”).
Distance between the countertop/stove3.
to the range hood.
Height of hood and duct cover.4.
For the most efficient & quiet operation:
A distance of 27” to 30” is recommended*•
between stove top and the bottom of range
hood.
•
It is recommended that the range hood be
vented vertically through the roof through
8” (20.3 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 pro-
vide efficient performance.
The vent system must have a damper. If•
roof or wall cap has a damper, DO NOT
use damper (if supplied) on top of the range
hood.
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.
