For vented models:
Vent system requirements
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 vent only. Rigid metal vent is recommended. Do not use plastic or metal foil vent.
Flexible vent is not recommended. Flexible vent creates back pressure that greatly reduces the hood's performance.
• 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 |
supplied with the range hood. |
• Use duct tape to seal all joints |
in the vent system. |
