Description
The Field Controls GVD-4PL 4” Automatic Gas Vent Damper is a 24V motorized damper that controls the flow of exhaust gas to maximize the efficiency of gas-fired HVAC equipment. Without the harness, this vent damper is an effective way of preventing heat loss because it closes the vent when the burner is not in use, keeping warm air in the system. Suitable for furnaces, boilers and water heaters, it increases energy efficiency, decreases fuel consumption, and decreases standby heat loss. The better indoor air quality is achieved by eliminating backdrafts and is therefore a welcome addition to residential and commercial HVAC systems.
