Anstoss Ignition transformer UBZ 4 (12) TYPE2 07000582

The Anstoss UBZ 4 (12) TYPE2 ignition transformer (SKU 07000582) is designed for ignition systems in gas and liquid fuel burners. It operates at a supply voltage of 12 V with a power consumption of 1.5 W. The transformer has a voltage tolerance of +20% / -30% and can operate in ambient temperatures up to 120 °C. Its application range is 14–248 °F. This model features design variant 973 and is equipped with silicone-insulated ignition cables.

When selecting a replacement ignition transformer of this type, verify that the primary voltage matches the burner control output and that the secondary voltage and current are sufficient for the electrode gap and flame ionization system. Check the mounting dimensions and connector pattern to ensure a direct fit. The ignition cables must be silicone-insulated to withstand high voltage and heat.

Common failure modes for ignition transformers include cracked or hardened ignition cables, which can leak spark to earth, potentially being mistaken for a faulty transformer. Other issues may include internal short circuits or open windings, leading to no spark or weak spark at the electrode. Symptoms on the equipment include failure to ignite, intermittent ignition, or burner lockout.
