How a Vent Damper Works
Installed in the flue pipe between the boiler and chimney, the vent damper’s blade automatically closes each time the burner cycles off. This blocks the flow of warm conditioned air escaping up through the flue during standby periods. When the burner fires again, the damper opens to allow safe exhaust of combustion gases — maintaining safe, efficient system operation cycle after cycle.
