Field Controls 00963801 Control Els PW 17895 25") against the existing unitThe Field Controls 00963801, designated as the Model 6"M, is a heavy duty barometric draft control engineered for precision regulation in oil fired boilers, wood stoves, and coal burning applications. This 6 inch draft regulator maintains constant draft by compensating for changes in atmospheric pressure and stack temperature, ensuring optimal combustion efficiency and preventing excessive heat loss. Designed for high stability performance, the gate
