ACV Ionization electrode 537DX009

The ACV ionization electrode 537DX009 is a consumable component designed for use in the flame zone of compatible burners. It operates by conducting a small rectified current through the flame to prove its presence. This electrode is resistant to soot accumulation. It is compatible with ACV BG60, Prestige 50 MK2, Prestige 75 MK2, and HeatMaster 85 models.

When selecting a replacement ionization electrode of this kind, critical parameters include overall length, rod bend, diameter and condition of the ceramic insulator, electrode gap, and mounting flange design. These must match the original part to ensure correct flame sensing and burner operation. For burners with a pilot burner, the electrode is typically positioned in the pilot flame path.

Common failure modes for ionization electrodes include erosion of the tip, cracking of the insulator, sooting, and gradual drift of the gap. These issues can extend ignition time or cause burner lockout. Periodic inspection is recommended to detect such failures.
