ACV Electrode 537DX007

The ACV Electrode 537DX007 is a bent, single-wire electrode used for ionization and ignition in gas burners. It is designed to fit ACV BG2000, CA 400, CA 600, HeatMaster 100, and HeatMaster 120 models. This electrode is resistant to soot, ensuring operation in flame zones. It serves to deliver the ignition spark or prove flame presence by conducting a small rectified current.

When selecting an electrode of this type, ensure the length, bend, insulator diameter, spark gap, and mounting flange shape match the burner series. The electrode must be positioned correctly relative to the burner head or pilot burner; incorrect gap or alignment can cause ignition failure or loss of flame signal. Compare the old part's dimensions and configuration before ordering.

Common failure modes include eroded tip, cracked ceramic insulation, sooting, or a drifting gap that prolongs ignition. Symptoms may include difficulty starting, intermittent flame loss, or no ignition. Check the electrode for physical damage, soot buildup, and proper gap alignment.
