Technicians should always identify the cause of the overheat condition before installing the new fuse

this is a uni-directional drier

Industry best practice for HVACR contractors is to replace the cover gasket every time the pump head is removed

Field Controls 02722701 Control 320819-301 Ensure the hot and neutralThe 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 .
