What it is

The Ideal 173512 is a detection lead used on Ideal Isar HE and Icos System HE appliances. It forms the electrical link between the flame detection electrode and the appliance control board, carrying the small signal that tells the board whether a flame is present. A sound lead keeps that signal clean, so the appliance can prove ignition and run without nuisance lockouts.

Signs this part needs replacing

  • The appliance fires, then shuts down because the board cannot confirm a flame
  • Repeated lockouts on start-up, sometimes clearing on a reset and returning later
  • Intermittent running with the burner dropping out mid-cycle
  • Visible damage to the lead: cracked or brittle insulation, scorched sleeving, or a loose crimp at the electrode or board end
  • Continuity readings that change when the lead is flexed or moved

Before you order

  • Confirm the appliance model and, where shown, the GC number against the data plate before ordering
  • Compare the old lead's part number and connector arrangement with the 173512 lead
  • Inspect the detection electrode and its insulation at the same time, as a worn electrode can mimic a faulty lead
  • Isolate the appliance electrically before removing or refitting the lead
