The Lochinvar & A.O. Smith 100109908 Flame Sensor is used in gas-fired heating systems. The principal one that we are going to discuss is functions based on the detection of a flame employing the use of infrared detectors. If the flame is out or does not light up, a sensor triggers the system’s control board, preventing further gas flow and dangers. This sensor is used commonly in boilers, furnaces, and water heaters. The benefits of using this flame sensor are improved safety, efficiency, and reduced maintenance. Thus, the sensor ensures protection against carbon monoxide poisoning and other risks, if the flame detection is provided properly.
