What it is

The Ideal 176561 orifice kit is a metering injector assembly for the LPG80 variant of Ideal's commercial boiler range. The orifice is the fixed-diameter restriction that controls the volume of gas delivered to the burner, so its bore size must match the fuel and appliance rating exactly. This kit carries a 5.9mm orifice, the size specified for LPG80 appliances running on liquefied petroleum gas.

Signs this part needs replacing

  • Burner lights but the flame is weak, unstable or lifts off the burner head
  • Sooting, discolouration or deposits around the burner and heat exchanger
  • Combustion readings drift outside the expected range for the appliance, with rising CO or incorrect CO2
  • Heat output noticeably below the rated input for the boiler
  • Visible damage, corrosion or blockage at the orifice bore

Before you order

  • Confirm the appliance is the LPG80 variant and that a 5.9mm orifice is the correct size for your model and gas type
  • Check the GC number and data badge on the appliance before ordering, as the same model family uses different orifices across fuel types and outputs
  • Note the alternative part number 1782354 when cross-referencing older documentation or stock records
