What it is

The Navien gas conversion kit allows an NCB500 series combi boiler to be converted from natural gas (NG) to liquefied petroleum gas (LP). It is a manufacturer-supplied kit for the Navien NCB500-1S and NCB500-2S combi ranges. The kit provides the components required to set the appliance up for the correct gas family.

Signs this part needs replacing

  • The boiler is being commissioned on an LPG supply but is currently set for natural gas.
  • The property's gas supply has changed from mains natural gas to bulk LPG or bottled LPG.
  • The appliance is running on the wrong gas family, giving poor combustion readings or unstable flame.
  • A gas conversion is required to bring the installation in line with the manufacturer's instructions for the fuel in use.

Before you order

  • Confirm the boiler model against the fitment list above.
  • Confirm the fuel being converted to and from — this kit covers NG to LP only.
  • Check the appliance serial number against the range covered by this kit.
  • Conversion must be carried out by a competent, Gas Safe registered engineer.
