13″ X 18″ Lyemance Chimney Damper

The Lyemance Damper can be installed in minutes and comes with a tube of silicone adhesive for mounting to the top of the tile liner. The lid of the damper is spring-loaded and normally in the open position. It is shut by means of a stainless steel cable which extends down the inside of the chimney flue and is attached to a hook mounted in the fireplace opening. Each die cast aluminum damper is completely assembled and includes a 32′ cable. Longer cables are available.

40′ Cable 50′ Cable.

*Top sealing dampers are not recommended with gas logs- failure to open could cause carbon monoxide to back up into the house.
