Important!
Make sure that the gas supply pressure of
the appliance obeys the recommended values. The
adjustable connection is fixed to the comprehensive
ramp by means of a threaded nut G 1/2". All the
components shown in the figure have already been
assembled in the factory. The appliance, before leaving
the factory, has been tested in order to give you the

Liquid gas
Use the rubber pipe holder for liquid gas. Always en-
gage the gasket. Then continue with the gas connec-
tion.
The flexible pipe is prepared for apply when:
– it can not get hot more than room temperature, high-
er than 30°C;
– it is no longer than 1500 mm;
– it shows no throttles;
– it is not subject to traction or torsion;
– it does not get in touch with cutting edges or corners;
– it can be easily examined in order to make sure its
condition.
The control of preservation of the flexible pipe consists
in checking that:
– it does not show cracks, cuts, marks of burnings on
the two ends and on its full length;
– the material is not hardened, but shows its correct
elasticity;
– the fastening clamps are not rusted;
– expired term is not due.
If one or more defects are visible, do not repair the
pipe, but replace it.

Injectors replacement
1. Remove the pan supports.
2. Remove the caps and crowns of the burner.
3. With a socket spanner 7 remove the injectors and
replace them with the ones which are necessary
for the type of gas you use (see table in "Technical

4. Assemble the parts, follow the same procedure
backwards.
5. Replace the rating plate (it is near the gas supply
pipe) with the one for the new type of gas supply.
You can find this plate in the package supplied
with the appliance.
If the supply gas pressure is changeable or different
from the necessary pressure, you must fit an applicable
pressure adjuster on the gas supply pipe.
Adjustment of minimum level
To adjust the minimum level of the burners:
1. Light the burner.
2. Turn the knob on the minimum position.
3. Remove the knob.
4. With a thin screwdriver, adjust the by-pass screw
position.

A) The by-pass screw
• If you change from natural gas G20/G25 20/25 mbar
to liquid gas, fully tighten the by-pass screw in.
• If you change from liquid gas to natural gas G20/G25
20/25 mbar, undo the by-pass screw approximately
1/4 of a turn (1/2 of a turn for Triple Crown burner).
Warning!
Make sure the flame does not go out
when you quickly turn the knob from the
