ACV Electrode 215-15-LH 537DX029

The ACV Electrode 215-15-LH (SKU 537DX029) is a dual ceramic ionization and ignition electrode from ACV. It is designed for use in Prestige 50 MK2, Prestige 75 MK2, HeatMaster 71, and HeatMaster 101 boilers. This electrode is resistant to soot, which helps maintain consistent performance. It serves to ignite the fuel-air mixture and prove the flame via ionization current.

When selecting a replacement electrode of this type, verify the physical dimensions and geometry: overall length, bend angle, insulator diameter, spark gap, and mounting flange shape. Ensure the tip position and gap match the manufacturer's settings for the specific burner model. Incorrect clearance can cause hard starting or loss of flame signal. Always compare the old part with the new one before installation.

Common failure modes include erosion of the tip from repeated sparking, cracking of the ceramic insulator from thermal shock, sooting that bridges the gap, and gradual drifting of the spark gap that lengthens ignition time. Symptoms on the equipment may include hard starting, delayed ignition, or loss of flame signal. Inspect the electrode for visible damage, soot buildup, or gap changes during routine maintenance.
