Description
- The Lyemance Damper eliminates as much as 90% of the air loss of a traditional damper, proving to save you up to $100 in a single heating session.
- It is designed to lock in heat, while keeping rain, snow, and debris from entering the chimney.
- Top sealing dampers are not recommended with gas logs- failure to open could cause carbon monoxide to back up into the house.
