Gas Vent Dampers, GVD Models

Improves gas boiler efficiency. Keeps cold air out, warm air in.

The Gas Vent Damper works automatically to allow natural draft during appliance operation while preventing residual appliance heat and conditioned air from escaping during off cycles. It also prevents the infiltration of cold air during down drafts. Field Controls gas vent dampers (GVD) are made of stainless steel and is available in 8 sizes, 4″ through 10″ and 12″.

Dual safety switches allow the burner to fire only when the damper is in the open position. The GVD will not interfere with existing appliance safety controls, when properly installed.
