Description
The Field Controls 46198901 (Model 4″MG1) is a 4-inch double acting barometric draft control engineered specifically for gas-fired heating applications. Designed to automatically regulate flue draft, this control helps maintain consistent combustion efficiency and protects your heating equipment from the damaging effects of excessive draft or backdraft conditions.
How It Works
The double acting design allows the barometric damper to respond to both positive and negative pressure fluctuations in the flue, swinging open in either direction as needed. This self-regulating action stabilizes draft pressure within the flue system, ensuring the burner receives the correct air-to-fuel ratio for safe, efficient combustion.
