What it is

The Johnson & Starley lead detection electrode (part number 1000-0522690) is a flame detection component for Reno and Renoxtra gas boilers. It monitors the presence of a flame at the burner and signals the boiler control system. This electrode is used to ensure safe ignition and operation.

  • Repeated flame failure faults
  • Boiler fails to detect flame and shuts down
  • Intermittent operation or no ignition
  • Visible damage or corrosion on the electrode or lead

Before you order
