What it is
The ZT812 is an ignition transformer manufactured by EOGB, supplied with a 1.5m ignition cable. It forms part of the ignition circuit on gas-fired boiler appliances, providing the high-voltage supply that generates the ignition spark at the burner.
Signs this part needs replacing
- The boiler attempts to fire but no spark is produced at the burner
- The appliance locks out repeatedly on an ignition attempt
- Ignition becomes intermittent, with the boiler firing only some of the time
- Visible burning, cracking, swelling or soot tracking on the transformer body or cable
Before you order
- Check the existing transformer is marked ZT812 or matches the same reference
- Confirm the required ignition cable length of 1.5m suits the routing on the appliance
- Check whether the appliance uses an EOGB, Honeywell or Satronic control arrangement
- Inspect the ignition electrode and lead terminals for damage before fitting a new transformer
