6" x 10" Flue Sentinel Automatic Damper

Field Controls will custom make a square or rectangular flue damper to your specific size requirement. Flue Sentinel is an electronic damper that automatically opens when you turn on your gas logs and closes when you turn them off. It’s installed at the top of your chimney so you never see or hear it operate, but you will immediately notice the difference. No more cold drafts coming down the chimney and no more heated air escaping from the chimney. Flue Sentinel can save as much as 30% on your energy bill, paying for itself in no time.
