Anstoss Ignition transformer UBZ 6 (12) 07000586

The Anstoss UBZ 6 (12) 07000586 is an ignition transformer from the Anstoss range, designed to step up mains voltage to a level sufficient to produce a spark at the electrode gap. It is energized only during the ignition period, under command from the burner control. This transformer works in conjunction with the ignition electrode and the high-voltage ignition cable. It is selected based on secondary voltage and current, primary voltage (commonly 230 V, but also 110 V and 24 V), duty cycle, mounting and terminal type, and cable connector pattern.

When replacing an ignition transformer of this type, confirm the primary voltage and secondary output rating from the existing transformer or the burner manual. Check the mounting dimensions and connector pattern to ensure a direct mechanical and electrical fit. Parts of this class are selected by secondary voltage and current, primary voltage, duty cycle, mounting and terminal type, and the cable connector pattern.

A hardened or cracked ignition cable can leak the spark to earth and simulate a faulty transformer, so inspect the cable before replacing the transformer. If the transformer fails, the burner may not ignite or may shut down during operation. Check the high-voltage cable and connections for damage or corrosion.
