ACV Electrode 537DZ043

The ACV Electrode 537DZ043 is a replacement electrode for ACV boilers, designed for ignition and flame sensing in the burner. It has an electrode length of 100 mm and is resistant to soot buildup. This electrode fits ACV Delta Pro 45, Delta Pro 65, CA 150, CA 200 Compact, and CA 300 Compact models.

When selecting a replacement electrode of this type, verify that the overall length, bend of the electrode tip, diameter and material of the ceramic insulator, spark gap (for ignition electrodes), and mounting flange or bracket pattern match the original. The electrode shape must correspond to the burner series and combustion head geometry. Before ordering, measure these parameters and compare them with the specifications of the part to ensure proper fit.

Failure of this type of electrode typically shows as an eroded or rounded tip, a cracked or sooted ceramic insulator, or a drifting gap that lengthens ignition time and can lead to lockout. Sooting may indicate poor combustion or a misaligned electrode. A worn or cracked electrode can cause intermittent ignition faults or a weak flame signal that the control interprets as flame failure.
