The Field Controls 01952701 is a 12-inch Model M+MG2 barometric draft control designed for heavy-duty commercial or residential applications. This dual-acting regulator maintains precise overfire draft for oil-fired, gas-fired, wood, or coal-fired appliances. By stabilizing the draft regardless of atmospheric changes, it prevents excessive fuel consumption and protects the heat exchanger from thermal stress. The 12" M+MG2 features a gate weighted for extreme sensitivity, ensuring it responds to minute pressure fluctuations within the flue. For gas applications, it operates as a double-acting control to relieve backpressure, while for oil or solid fuel, it provides the requisite constant draft regulation needed for high-efficiency combustion. This unit is built with a heavy-gauge galvanized steel ring and a stainless steel knife-edge bearing to ensure long-term reliability in high-temperature environments. Integrating this Type M+MG2 draft regulator into a 12-inch flue system ensures peak burner performance and reduced soot accumulation. Key Benefits for Contractors Universal Application: Engineered for multi-fuel compatibility, including oil, gas, and solid fuel heating systems. Draft Stability: Maintains a consistent overfire draft, preventing burner flame-outs and inefficient combustion cycles. Precision Calibration: Adjusts easily to specific draft requirements, ensuring compliance with appliance manufacturer specifications. Double-Acting Functionality: Provides essential safety for gas-fired equipment by opening outward to vent pressure spikes. Durable Construction: High-grade materials resist corrosion and mechanical wear in demanding venting environments. Common Questions Is the Field Controls 12" M+MG2 suitable for positive pressure chimneys? No, this barometric draft control is designed for atmospheric or negative pressure venting systems. It should not be installed on positive pressure power-vented configurations. Does this unit come with the mounting collar? This model is usually provided as the draft control head. Ensure your flue pipe is prepped or a compatible tee/collar is available for the 12-inch opening. Can I use this on a 12-inch wood stove flue? Yes, the Field Controls 01952701 is rated for solid fuel applications, including wood and coal, to prevent over-firing and excessive heat loss up the chimney.
