Ideal Conversion Kit LPG to NG 176658

The Ideal 176658 is a fuel conversion kit for the Logic+ Combi range of gas boilers. It contains the components needed to change the appliance between natural gas (NG) and liquefied petroleum gas (LPG/propane), so the boiler can be set up to match the fuel supplied to the property. The kit is fitted to the gas-carrying parts of the boiler and is specific to the Logic+ Combi platform from prefix ZJ onwards.

• The boiler has been moved to a property or supply point where the fuel type differs from the one it was set up for.
• Combustion readings are outside the range expected for the fuel being supplied to the appliance.
• The burner shows unstable or poor flame characteristics after a change of gas supply.
• A conversion is being carried out as part of a planned changeover between natural gas and propane.
• The existing conversion components are damaged, missing or no longer matched to the boiler's fuel setting.

• Check the boiler's model and serial prefix — this kit is listed for Logic+ Combi units from prefix ZJ onwards.
• Confirm the GC number and model against the compatibility list before ordering, as the kit is fuel- and model-specific.
• Note the alternative part number 1781996 when cross-referencing older documentation or stock records.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
