Brahma Ignition transformer 15111001

The Brahma Ignition transformer 15111001 is a step-up transformer used in gas burners, and can also be used in diesel burners when only one ignition electrode is required. It operates only during the ignition phase, under command from the burner control, stepping up the mains voltage to produce a spark at the electrode gap. The transformer supports flame detection via ionization or UV/IR methods. Its ignition cable insulation is silicone, designed to withstand high voltage and heat.

When selecting a replacement ignition transformer of this type, verify that the secondary voltage and current, primary voltage (commonly 230 V, but 110 V and 24 V variants exist), duty cycle, mounting arrangement, terminal type, and cable connector pattern match the existing installation. Confirm the primary voltage matches the supply and inspect the cable condition. The mounting and terminal pattern should be checked to ensure a direct mechanical and electrical fit.

A hardened or cracked ignition cable can leak the spark to earth, which may mimic a faulty transformer and lead to nuisance lockouts. Other failure modes include internal short circuits or open windings, resulting in no spark at the electrode gap. Check the cable condition and primary voltage supply when troubleshooting.
