What it is
The Baxi 720774601 is a high voltage wiring harness for the timer, classed as a wiring part. It is manufactured by Baxi and is used in the electrical connections of compatible gas boilers to carry the high voltage supply to the timer.
Before you order
- Check the appliance model and serial number ending against the fitment list, as several models are only compatible from specific serial number ranges.
- Confirm the gas type (NG or LPG) for DUO-TEC 2 Combi models, as separate part listings apply to each.
- Isolate the appliance from the electrical supply before any work on the harness.
