Velocity Boiler Works (Crown) 431003 Phantom/Shadow Sensor Kit

The Velocity Boiler Works (Crown) 431003 Phantom Shadow Sensor Kit with Long Well 121371L 1/2” F is an accessory that replaces the original sensor of some oil-fired hydronic heating systems. The sensor identifies the existence and quality of the flame and conveys the data to the boiler control board. If the sensor is bad, the combustion is incorrect, the efficiency is low, or the system shuts down for safety purposes. This replacement kit is intended for cast iron heat exchangers which are present in many oil-fired boilers. The kit is designed to work with both natural gas and propane-fired systems. This kit is designed to allow the safe-efficient operation of your boiler by replacing a faulty sensor.
