What it is

The Biasi BI1536104 is an NTC flue temperature probe with an integrated safety thermal fuse, manufactured by Biasi for its Riva Plus HE, Riva Compact HE and Garda HE gas boiler ranges. It monitors flue gas temperature and provides over-temperature protection as part of the boiler's safety circuit.

Signs this part needs replacing

  • Boiler locks out or displays a flue-related fault code
  • Repeated overheat or flue temperature trips
  • Open circuit on the thermal fuse when tested for continuity
  • Erratic or implausible flue temperature readings
  • Boiler cycling or failing to fire consistently

Before you order

  • Confirm your boiler model and GC number against the fitment list above
  • Check the existing probe's part number and connector type match BI1536104
  • Isolate the electrical supply and gas before removing the probe
  • Inspect the flue and probe wiring for damage before fitting
