Rheem-Ruud 62-21744-01 Flame Sensor

The Rheem-Ruud 62-21744-01 Flame Sensor is an essentialpart of the gas-fired HVAC systems. This tiny aluminum sensor that is only 1/4" is reliable in detecting the presence and quality of a flame. As the flame is constantly observed, the sensor serves to be of significant value to both safety and efficiency. If for instance the flame becomes instable or ceases to burn, the sensor promptly calls for the system to turn off, in order to minimize on possible risks. This rapid response also aids the control of the combustion process and thereby ensures a minimum consumption of fuel and a minimal emission of the hazardous products.
