Field Controls 46487201 Vent Damper R-410A or frost formation on theThe Field Controls 46487201 (Model GVD 7PL) is a 7 inch automatic vent damper designed to optimize thermal efficiency in gas fired atmospheric heating systems. Operating on a 24Vac circuit, this power vent damper prevents standby heat loss by sealing the flue pipe when the burner is off, effectively maintaining heat within the heat exchanger. This model is engineered for seamless integration with intermittent ignition and standing pilot systems. It
