Field Controls 01950201 Control

The Field Controls 01950201 (Model 10"M+MG2) is a heavy-duty, 10-inch barometric draft control designed for precise regulation on commercial and large residential appliances. Engineered for versatility, this triple-acting draft regulator maintains a constant draft between 0.02" and 0.08" W.C. by counteracting atmospheric pressure changes and wind fluctuations. Its rugged build features a heavy-gauge gate resting on a stainless steel knife-edge, supported by self-aligning, self-cleaning bearings to ensure maximum sensitivity and minimal friction. When used in gas-fired applications, the double-acting capability allows the unit to bleed air into the flue to assist the chimney, while single-acting operation is ideal for solid fuels like wood or coal. By stabilizing the velocity of combustion gases, this barometric damper ensures complete fuel combustion and improved heat extraction across oil, gas, and multi-fuel systems. For high-output boilers or furnaces, the Field Controls M+MG2 series provides on-the-job adjustability that optimizes burner performance and reduces maintenance requirements for 10-inch diameter vent pipes.

• Multi-Fuel Compatibility: Universally applicable for oil-fired boilers, commercial gas furnaces, and coal-burning appliances.
• Precision Sensitivity: The stainless steel knife-edge pivot and 78.5 sq-in nominal capacity deliver highly accurate responses to draft changes.
• Fuel Efficiency: Extends heat exchanger residence time, allowing more heat to be extracted while reducing combustion gas velocity.
• Industrial Durability: Rugged design handles the high stack temperatures and demanding draft requirements of industrial environments.
• Easy Calibration: Features simple, on-the-job adjustments to meet specific manufacturer draft specifications using a draft gauge.

When should I use a double-acting versus single-acting draft control?
Use the 10"M+MG2 as a single-acting control for oil or solid fuels (wood/coal). For gas-fired-only or dual-fuel applications, the unit should be configured as double-acting (often with an optional thermal switch) to provide both relief and draft assistance.

What is the recommended pipe size for the 01950201 model?
This 10-inch draft control is designed for vent pipes with a diameter between 9 and 10 inches and a circumference range of 28-1/4 to 31-1/2 inches.

Does this unit replace a traditional draft hood in gas systems?
Yes, the Field Controls M+MG2 is frequently specified instead of a draft hood in gas installations to allow the appliance to utilize the chimney’s natural pull more effectively.
