What it is

The Biasi KI1004147 is a fourteen-rail burner assembly used in a range of Biasi gas boilers. It carries the gas/air mixture across the burner rails to produce the flame that heats the appliance's primary heat exchanger. The burner is manufactured by Polidoro for Biasi and is listed under the superseded code KG1004147.

Signs this part needs replacing

  • Lazy, yellow or lifting flame instead of a clean blue flame
  • Soot deposits or discolouration across the burner rails or heat exchanger
  • Visible cracking, corrosion or distortion of the burner rails
  • Poor combustion readings, including elevated CO or unstable CO2
  • Unstable ignition or flame rollout at the burner

Before you order

  • Check the boiler model number against the fits list above before ordering
  • Confirm the existing burner has fourteen rails
  • Check the part number on the old burner or the manufacturer's parts list for your appliance
  • Verify any GC number for your appliance against the manufacturer's documentation
