Anstoss Ignition transformer ZAG 2 07000089/02

The Anstoss ZAG 2 ignition transformer is designed for gas and oil burners in heating equipment. It generates a high-voltage pulse to ignite the fuel mixture and operates only during the ignition phase. Supply voltage is 220–240 V at 50–60 Hz, with a power consumption of 10 W. The compact housing allows convenient installation, and the unit is resistant to voltage fluctuations. Maximum ambient temperature is 85 °C.

When replacing an ignition transformer of this kind, verify that the secondary voltage and current, primary voltage, duty cycle, mounting pattern, terminal type, and cable connector arrangement match the original part. The primary supply is commonly 230 V, but 110 V and 24 V versions exist. Check that any frequency rating matches the local mains supply. Before condemning the transformer, inspect the silicone-insulated ignition cable and the electrode gap, because a damaged cable can leak the spark to ground and mimic a transformer fault.

The usual failure mode is loss of spark at the electrode, so the burner fails to light. However, a hardened or cracked ignition cable can leak the spark to ground and mimic a transformer fault, so inspect the cable and electrode connections before replacing the transformer.
