Field Controls 02722701 Control 320788-704 automatically interrupting the electrical circuitThe Field Controls 6" RC Barometric Draft Control (Part Number 02722701, also listed as 2722701) is a precision engineered component designed for high efficiency oil and coal heating systems. As a veteran tech knows, consistent draft is critical for proper combustion; this Type RC draft regulator maintains optimal overfire draft by compensating for changes in atmospheric pressure and chimney temperature. It features a calibrated range of . 02"wc to .
