crown engineering 20996 Cleaver-Brooks Electrode 873-70

crown engineering 20996 Cleaver-Brooks Electrode 873-70 is a flame-sensing and ignition component used in burner control assemblies. It is installed in combustion systems to detect flame presence, and provide feedback to the control circuit, ensuring proper sequencing during start-up and operation. Within HVAC systems, it is positioned in the burner section where it interfaces with the ignition system and combustion chamber. The electrode tip is designed for stable signal transmission under high-temperature conditions supporting flame detection, consistent system startup, and safe shutdown response during operational cycles and control monitoring.
