Burnham Automatic Vent Damper

The Burnham Automatic Vent Damper is a boiler flue damper that helps gas-fired heating systems run efficiently. It is also called a flue damper or automatic draft damper. It is installed in the vent connection of a Burnham boiler. It opens when the boiler fires so combustion gases can exit safely. It closes when the boiler cycles off, which limits heat loss up the chimney.

Key Features:

• Automatic operation opens and closes the damper in step with the boiler's burner cycle
• Helps cut standby heat loss through the vent, improving system efficiency
• Aluminum base construction in the models listed
• Supplied with a matching wiring harness and a loose knockout, as listed for the models
• Made as a Burnham replacement part for Burnham boiler lines, including the New Yorker series
• Available in multiple vent diameters to suit different Burnham boiler models

Choose the damper whose size and harness match your boiler model. Burnham vent dampers are a dependable way to restore proper venting and efficient operation in a gas-fired hydronic heating system.
