Brahma Ignition electrode BR90 12431013

The Brahma Ignition electrode BR90 (SKU 12431013) is an ignition electrode designed to generate a spark for burner ignition. It has an electrode length of 123 mm, a diameter of 3 mm, and a rod length of 25 mm with a 120° angle. The ceramic insulation is 8 mm in diameter and 80 mm long, with a distance to bracket of 60 mm. It features a plug size of ø4 mm and a flange with one hole. This electrode replaces the discontinued part numbers 11004258 and 246.946.010.

When selecting a replacement electrode of this type, verify the total length, rod diameter, bend angle, insulator diameter, and mounting flange pattern against the existing part. The distance from the bracket to the electrode tip and the plug size must match the burner's ignition cable and mounting configuration. Ensure the electrode's geometry aligns with the combustion head or pilot burner assembly.

Typical failures include a worn or eroded tip, cracked ceramic insulation, sooting from incomplete combustion, and a drifting gap that lengthens ignition time. When these occur, the burner may fail to ignite or exhibit delayed ignition. Check the electrode's physical condition and gap against the burner control's requirements.
