ACV Electrode IONi.bent 537DX010

The ACV Electrode IONi.bent 537DX010 is an OEM-certified ionization and ignition electrode, type designations A16 and A34. It is designed for use in ACV BG2000 ALFA-dperf. and HeatMaster 120 boilers. This electrode is resistant to soot buildup, ensuring consistent flame sensing and ignition performance.

When selecting a replacement electrode of this type, verify the overall length, bend of the rod, diameter and integrity of the ceramic insulator, electrode gap, and mounting flange configuration. The physical geometry must match the combustion head and burner arrangement; an exact match is required to avoid ignition delays or lockouts. Compare the old electrode's bend and insulator length as a guide, and ensure the new part sits firmly in the mounting hole with the correct gap relative to the burner tip or pilot tube.

Typical failure modes include erosion of the tip from repeated sparking, cracking of the ceramic insulator due to thermal shock, soot buildup that shorts the signal, and a drifting gap that lengthens ignition time. These issues can cause ignition delays, lockouts, or unreliable flame sensing. Inspect the electrode for a clean, uncracked ceramic and a sharp tip during replacement.
