ACV Electrode 53429161

The ACV Electrode 53429161 is a consumable component used in ACV boilers, categorized under ionization and ignition electrodes. It serves either to deliver a high-voltage spark for ignition or to sense the presence of a flame by conducting a small rectified current, depending on its wiring. This electrode is compatible with Prestige 50 MK2, HeatMaster 85, CA 150 Comfort, ACV Compact 28, and ACV Comfort Delta Pro 65 models. It is resistant to soot, which helps maintain its function in the flame zone.

Parts of this type are selected primarily by their physical geometry: the length and bend of the electrode rod, the diameter and straightness of the ceramic insulator, the gap between the electrode tip and the burner earth, and the mounting flange design. The shape must match the combustion head or pilot burner for which the electrode was originally intended. When replacing, ensure the replacement matches the original in rod length, insulator dimensions, mounting hole pattern, and gap setting. Correct orientation in the flame zone is critical, and a leak check on the mounting gasket is advisable after installation.

Typical failure modes include erosion of the tip, cracks in the ceramic insulator that cause tracking or shorting, soot build-up that insulates the electrode, and a drifting gap that lengthens ignition time or prevents flame detection. When these occur, the equipment may exhibit delayed ignition, failure to ignite, or loss of flame sensing, leading to burner shutdown. Regular inspection during servicing is recommended to detect these issues early.
