What it is

The Ideal 176559 is an LPG orifice kit carrying a 3.9 orifice, produced by Ideal for its commercial boiler range. It sits in the gas train and meters fuel flow into the burner so the appliance burns correctly when running on LPG. It is listed for Ideal Commercial Evomax and Instinct Heat appliances.

Signs this part needs replacing

  • The boiler runs rich or lean after an LPG conversion
  • Flame lifts, becomes unstable or fails to hold at the burner
  • Combustion analyser readings fall outside the manufacturer's tolerance
  • The correct gas rate cannot be set at the meter
  • Soot deposits or heat discolouration appear around the burner

Before you order

  • Check the GC number and model on the appliance data badge against the compatibility list.
  • Compare the size marked on the existing injector; the 3.9 orifice is intended for LPG operation.
  • Note the alternative part number 1782348 when cross-referencing older documentation.
