Venting Requirements
Height & Clearance
• 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
(Not Included).
aluminum vent is recommended.
• DO NOT use 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 to the coun-
tertop/stove (Usually 36 Inches).
3.Distance between the countertop/stove to the
range hood.
We recommend (25.5’ to 27 1/2’ Inches).
4. Height of hood and duct cover.
For the most efficient & quiet operation:
• It is recommended that the range hood be
vented vertically through the roof through 6”
(15.24 cm) or bigger round metal / aluminum
vent work.
• The size of the vent should be uniform.
• Use no more than two 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 open-
ing around the cap.
