6.11 CONVERTING THE BOILER TO OPERATE ON LPG
If the boiler has to be converted for LPG, obtain the relative conversion kit. The gas conversion operation
must be carried out by a competent and suitably qualified Gas Safe registered engineer.
To convert to LPG the following operations are required:
• Isolate the appliance from the electric and gas supplies.
• Replace the injector located on the upper fitting of the gas valve and re-seal the connections (Fig. 7.6).
• Re-instate gas and electric supplies.
• Calibrate the new fan speed for LPG (Section 6.13).
• Check / adjust the correct CO
• After completing the conversion, apply the sticker (supplied in the conversion kit) near the boiler data plate.
Using an indelible marker pen, delete the data relative to the old type of gas.
These adjustments must be made according to the type of gas used, given in the table (Section 3).
