The Field Controls 01986901 is a 14-inch M+MG2 Barometric Draft Control engineered for high-precision pressure stability in commercial and industrial heating systems. Designed as a dual-acting regulator, this barometric damper is compatible with oil, gas, wood, and coal applications, providing a versatile solution for maintaining consistent overfire draft. The Model 14"M+MG2 features a heavy-duty gate assembly and professional-grade bearings to ensure minimal friction and long-term reliability under high-temperature conditions. By neutralizing fluctuations caused by atmospheric changes and stack temperature variances, this Field Controls draft regulator optimizes combustion efficiency and reduces fuel consumption. For contractors, the critical value lies in its gate sensitivity and adjustment accuracy, which are essential for meeting strict HVAC draft pressure specifications. Proper installation of this 14-inch draft control improves equipment longevity by preventing excessive heat loss and flame rollout in multi-fuel venting systems. Multi-Fuel Compatibility: Engineered for seamless integration with gas, oil, wood, or coal-fired appliances. Precision Draft Regulation: Maintains stable overfire draft to maximize burner efficiency and reduce soot buildup. Industrial Build Quality: Features a rugged 14-inch gate designed for demanding commercial chimney and vent stacks. Universal Application: Functions effectively as a single or double-acting control depending on the specific venting requirements. Improved Combustion: Prevents excessive chimney pull that can lead to wasted energy and inefficient heat transfer. Common Questions How do I adjust the 14" M+MG2 for specific draft settings? Adjustment is handled by moving the weight on the bracket to increase or decrease gate resistance. Use a manometer to verify the draft pressure at the appliance outlet during the commissioning process. Can this barometric damper be used for both positive and negative pressure stacks? No, barometric draft controls like the 14" M+MG2 are designed for negative pressure (natural draft) systems to regulate excessive pull; they are not intended for use with high-pressure power vents. Is the Field Controls 01986901 dual-acting? Yes, the M+MG2 series is designed as a double-acting control, which is a requirement for many gas-fired applications to allow for pressure relief in the event of a momentary downdraft.
