• 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. 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
installation:
1. Distance from the floor to the ceiling
2. Distance between the floor to the
countertop/stove
3. Distance between the cooking surface to
the range hood (recommend 24” to 30”)
minimum of 30” is required for gas cook top
4. Height of hood and duct cover
For the most efficient & quiet operation:
• 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.
• 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, 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.
