What it is
The Potterton Sensor Cable (X1) is a flame ionisation lead used on Potterton Commercial Sirius 2 and Sirius 3 FS series boilers. It carries the flame sensing signal from the burner assembly back to the boiler control, allowing the control to prove that a flame is established and hold the burner in operation. The part is listed under manufacturer part number 5142448 and is also catalogued as a flame/ionisation lead.
Signs this part needs replacing
- The boiler locks out shortly after the burner has lit, with the control failing to prove flame
- Repeated flame failure lockouts that clear on reset and then return
- Intermittent lockouts that are affected by movement or disturbance of the sensing lead
- Visible damage to the lead insulation, terminals or connector ends
- Flame sensing continuity that cannot be maintained at the control
Before you order
- Confirm the appliance model against the Sirius 2 or Sirius 3 FS fitment list above
- Check the existing lead routing and connection points on the boiler before removal
- Verify the manufacturer part number 5142448 against the lead currently fitted
- Isolate the appliance electrically and follow the manufacturer's servicing instructions before fitting
