Description
The Bosch HVAC 8738722789 Ionisation Electrode is used to monitor flame presence in combustion-based heating furnaces, in HVAC systems. It works as a safety sensing component that detects ionised particles within the flame during burner operation, confirming ignition and maintaining gas flow. It is typically installed in residential boilers, and furnace assemblies where it interfaces directly with the burner flame area to provide continuous flame verification. The component supports safe and stable heating operation by signaling control boards to shut off fuel supply if flame loss is detected in residential and light commercial applications.
