Height & Clearance
• Vent system must evacuate to the exterior
(through the roof or sidewall).
• DONOT terminate the vent system in an
attic or other enclosed area.
•
Use rigid metal/aluminum ventonly.
• NEVERuse plasticventor 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

For the most efficient & quiet operation:
• It is recommended that the range hood be
vented vertically through the roof through
8” (20.3 cm) round metal/aluminum vent or
vented horizontally through the wall
through a rectangular vent measuring 3 ¼’’
x10’’.
• 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 isused.
• The length of vent system and number of
elbows should be kept to a minimum to
provide efficientperformance.
• 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 duct tape to seal all joints in the vent
system.
• Use caulking to seal exterior wall or roof
opening around the cap.
