instructions given on this section.
Make sure that the gas supply pressure respects the values presented on rating plate and in
the spec on page 11.
Natural gas
This appliance leaves the factory set to operate using Natural Gas.
Make sure that the Natural Gas regulator supplied with the appliance is installed and, with
the triple ring burner operating at its maximum, adjust the test point pressure to 1.0kPa.
Universal LPG
To convert from Natural Gas to Universal LPG, ensure that the Natural Gas regulator is
replaced by the Test Point Assembly supplied with the appliance. Adjust the test point
pressure to 2.75kPa.
To adapt the appliance to a gas different from that for which it was set up (see rating label)
proceed as follows:
1. Remove the trivets
2. Remove the burners caps and diffusers
3. With a 7 mm socket spanner unscrew and remove the injectors.
4. Replace the injectors with those supplied corresponding to the gas available (see burner
and injector characteristics table)
5. Replace the various parts proceeding in reverse.
Setting the minimum flame
The flame on the small output is regulated by the factory.
When the injectors have been replaced or there are special
mains pressure conditions, it may be necessary to regulate the
minimum flame again. The operations necessary to set the
minimum flame are as follows:
1. Light the burner.
2. Turn the knob to the minimum position.
3. Take out the knob (and gasket if there is one).
4. LPG to NG: use a thin blade screwdriver to turn the bypass screw located above gas valve
shaft as shown on the image above. Turn gently the bypass screw clockwise to the end
completely then turn it anti-clockwise 1 turn for the triple ring, 3/4 turn for the rapid, 1/2 turn for
the semi-rapid and 3/8 turn for the auxiliary.
5. NG to LPG: use a thin blade screwdriver to turn the bypass screw located above gas valve
shaft as shown on the image above. Turn gently the by pass screw clockwise to the end.
6. Put the knob back on and turn it quickly from the maximum position to the minimum position,
checking that the flame does not go out.
7. For burners with safety valve make sure that the regulation obtained is sufficient to maintain
