Category Archives: Top Sealing Dampers

While most dampers are located in the throat of the fireplace, there are dampers that mount at the top of the chimney.

These dampers are designed to make your fireplace more energy efficient by sealing sealing the flue at the top rather than at the bottom. Sealing at the top keeps the cold air out and your warm air in and causes an automatic updraft in the flue when opened, (you will not have to warm the flue first).

Top mounted dampers are operated by a control mounted in the firebox and connected to the chimney top damper by a cable or chain. Chimney top dampers are often an economical alternative to replacing a rusted out or warped throat damper. Top mounted dampers will also keep rain and animals out of your chimney when in the closed position.
