Brahma Electrode 12438702

Brahma Electrode 12438702 is an ionization and ignition electrode with a total length of 543 mm. It features an ignition rod of 3 mm diameter and 300 mm length, ceramic insulation of 14 mm diameter and 230 mm length, and a plug for ignition cable of 6 mm diameter. This electrode is resistant to soot, making it suitable for applications where soot buildup is a concern. It is designed for use in burners and boilers to generate sparks for ignition or to prove flame presence.

When selecting a replacement electrode of this type, ensure the total length, rod diameter, insulator diameter, and mounting configuration match the original part. Measure the electrode length and bend, insulator diameter, spark gap, and mounting flange pattern against the burner specifications. The electrode must be positioned correctly relative to the burner head or pilot burner, and the ceramic insulator must be free of cracks. The connection to the ignition transformer cable must be clean and secure.

Typical failures of ionization and ignition electrodes include eroded tips, cracked ceramic insulation, sooting, and a drifting spark gap that lengthens ignition time. When an electrode fails, the burner may experience delayed ignition, failure to ignite, or loss of flame signal, leading to lockout. Check the electrode for signs of wear, soot accumulation, and proper gap alignment, and inspect the ceramic for cracks.
