7 inch Round Damper
I bought a Broan QML30SS. The directions were unclear about needing a damper. If i purchase a Broan damper, do I still need to use the round damper plate that comes with the hood? I am trying to find a way to connect from the 7 inch damper to my 7 inch duct.
Thank you for your question on the model QML30SS range hood. The QML30SS comes with a back draft damper for 3-1/4” x 10” rectangular duct work. If you are using 7” round duct work you would attach the 7” round duct plate (that comes with the unit) to the top of the hood. This gives you someplace to connect the 7” round duct work from your house. We do recommend that you install a 7” round back draft damper (purchased separately) somewhere in the duct line or at the roof or wall cap where the duct exits the house.

Will this work with a Model # CJD336SS hood?
Can it be purchased at Lowe's or Home Depot?
Thank you for your question on the model BP87Q seven inch round dampers for use with range hoods. The CJD336SS can be installed with 3-1/4” x 10” rectangular duct, seven inch round duct or non-ducted. If your hood is installed with seven inch round duct work, the BP87Q should work fine. Please contact the Technical Service Department at 800-637-1453 if you need further assistance.
