ACV Electrodes assy 53429060

The ACV Electrodes assy 53429060 is an ionization and ignition electrode assembly designed for ACV burners in the BM(r)21/31/51/101 series. It combines the ignition electrode, which generates the spark for lighting the burner, and the ionization electrode, which detects the presence of flame by sensing a rectified current through the flame. This assembly is compatible with ACV HeatMaster 60, HeatMaster 85, Prestige 50 MK2, Prestige 75 MK2, and CA 150 Comfort models. It operates directly in the flame zone and is a consumable part requiring periodic inspection and replacement.

When selecting a replacement electrode assembly of this type, compare the physical shape and dimensions of the old assembly, including electrode length, bend angle, insulator diameter, spark gap, and mounting flange configuration. Ensure the electrode gap matches the burner control's specification and that the ceramic insulator is clean and intact. Proper alignment with the burner head and, if present, the pilot burner is essential for ignition and flame signal.

Typical failure modes for this kind of electrode assembly include erosion of the electrode tip, cracking of the ceramic insulator, accumulation of soot on the surface, or a gradual increase in the spark gap. These issues can delay or prevent ignition, cause intermittent flame signal, or lead to burner lockout. Check the electrode for visible damage, clean soot deposits, and verify the spark gap is within specification.
