What it is
The plug ionisation is a flame sensing component used on Broag Commercial boilers. It sits in the combustion path and provides the flame signal the control board needs to confirm ignition and keep the burner running. This is the Broag part numbered 720402601.
Signs this part needs replacing
- The boiler locks out shortly after ignition or fails to prove flame
- Repeated flame failure faults on the control display
- Intermittent running, with the burner cutting out during a demand
- Ignition appears to occur but the boiler does not stay lit
- Visible damage, heavy contamination or a degraded connector at the ionisation plug
Before you order
- Confirm your appliance model against the manufacturer's parts list
- Check the part number on the existing component matches 720402601
- Inspect the lead and connector for heat damage or poor contact before replacing
- Verify the fault is flame sensing related and not a gas or ignition fault
