ACV Electrode 185mm straight dual ceram. 537DZ040

The ACV Electrode 185mm straight dual ceram. (SKU 537DZ040) is a straight dual-ceramic electrode with a length of 185 mm. It is designed for use in ACV boilers, including models Prestige 32 MK2, HeatMaster 71, Compact HR 30, Kompakt HR 18, and E Tech P 45. This electrode serves as an ignition or ionization component in the burner system, delivering spark or sensing flame presence. It is resistant to soot buildup, which helps maintain consistent performance.

When selecting a replacement electrode of this type, ensure the overall length, bend (straight), ceramic insulator diameter, spark gap, and mounting flange configuration match the original part. These dimensions are specific to the burner series, so verify compatibility with the boiler model. Do not attempt to bend a straight electrode; if a different shape is required, choose a part with the correct bend from the same series. During installation, seat the electrode correctly in the burner head and adjust the gap relative to the burner metal or pilot tube to the manufacturer's specification.

Typical failure modes include erosion of the electrode tip, cracking of the ceramic due to thermal shock, soot buildup that insulates the electrode, and a drifting spark gap. These issues can cause delayed ignition, loss of flame signal, or burner lockout. Check the electrode for visible damage, soot accumulation, and proper gap alignment when these symptoms occur.
