To modify the burner from Natural gas into L.P.G. and viceversa, proceed as follows: - remove the blast tube A
(see at “Removing the blast tube”); - remove the combustion head D from the adjusting rod G by loosing screw H,
and pull it out from gas tube F; - loosen screw B, pull out part C from head’s front side and the nozzle E
from the rear side; replace nozzle E with the needed one (recognisable from hole’s diameters, as shown
by the table hereby), then reassemble the whole in reverse order.
Note: When the operation is achieved, stick the label (supplied with) corresponding to the
type of gas used, on the existing one; at the end check again the combustion
and adjusting data as well according to the new type of gas.
