• Check that the duct size used is as required 6” or 8" per
blower unit's vent size and does not have sections with
smaller sizes between the hood and the Roof/Wall Cap
.
Range hood WILL NOT function efficiently with insufficient
duct size. For example: 7” duct over 6” top vent and not
sealed properly.
• Check if the duct is clogged or the damper (half-circular
flapper) is not installed correctly or opening properly. A tight
mesh on a side wall cap might also cause restriction to the
air flow.
The lights work but the blower is
not spinning at all or is rattling
• The blower might be jammed or scraping the bottom due to

wheel" section in Page 14 to adjust the fan wheel.

• Make sure the distance between the stove top and the
bottom of the hood is within recommended 24” and 30” in
distance. *Due to different ceiling height configurations, the
recommended height may not be applicable.
• Reduce the number of elbows and length of duct work.
Check if all joints are properly connected, taped and sealed.
• Make sure the power is on high speed for heavy cooking.
