Description
Brahma Electrode 12429069 is an ignition and ionization electrode with a total length of 114 mm. It features an electrode rod of 2 mm diameter, ceramic insulation, and a plug size of ø4 mm. This electrode is designed for use in burner systems to deliver sparks for ignition and to conduct flame-sensing current.
Choosing and fitting
When selecting a replacement electrode of this type, verify the total length, rod diameter, insulation material, and plug size match the original. The electrode shape and mounting arrangement must correspond to the combustion head geometry of the specific burner series. Measure the existing electrode's dimensions and compare them with the replacement before ordering.
Signs of failure
Common failure modes include erosion of the electrode tip from repeated sparking, cracking of the ceramic insulator due to thermal shock or mechanical stress, and sooting that can short the spark. A drifting gap may lengthen ignition time or prevent sparking. If the electrode fails, the burner may lock out within the safety time due to loss of flame signal.
