Burnham Boiler 8116325 Vent Damper R-410A Operating on 50Hz may causeThe Burnham Boiler 8116325 Vent Damper is a mission critical 8 inch automatic vent damper designed specifically for Burnham gas fired boilers. This GVD 8BN model functions as an electromechanical safety and efficiency device, preventing heated air from escaping through the flue when the burner is off. Built for high heat environments, the vent damper assembly ensures consistent HVAC efficiency by maintaining the thermal mass within the heat exchanger.
