Worcester Bosch Conversion Kit LPG to NG FS42 8716118213

The Worcester Bosch 8716118213 is a conversion kit that changes a Greenstar FS 42CDi ErP Regular floor-standing boiler from LPG operation to natural gas operation. It contains the components needed to re-jet and re-set the appliance so that it burns natural gas correctly. The kit is specific to the FS 42CDi ErP Regular range and is not interchangeable with other Greenstar models.

• The boiler is being moved from an LPG supply to a mains natural gas supply and the appliance is still set for LPG.
• Combustion readings are outside the expected range for the gas being supplied, with CO or CO2 figures that cannot be brought into specification by adjustment alone.
• Flame picture is unstable, with lift, yellowing or sooting at the burner.
• The appliance locks out or fails to establish a stable flame after a change of gas supply.
• A service or commissioning check shows the burner injectors or gas train components are not matched to the fuel in use.

• Check the appliance GC number and model plate against the compatibility table above before ordering; the kit is specific to the FS 42CDi ErP Regular range.
• Confirm the boiler's current gas setting and the gas supply it will run on after conversion.
• Check whether any gaskets or seals disturbed during the conversion need replacing at the same time.
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
