Flue Sentinel Low Profile Automatic Flue Dampers For Gas Fireplaces, FSM Models

Model FSM Millivolt Round Low Profile Round Flue Damper for Gas Fireplaces

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.

The FSM Millivolt Low Profile Round models for gas log fireplaces feature intermittent ignition and standing pilot ignition systems. Low Profile models are 6″ in height and require a chimney cap.
