Liquid gas
Use the rubber pipe holder for liquid gas. Always en-
gage the gasket. Then continue with the gas connection.
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 cor-
ners;
– 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.
Important! When installation is complete, make sure
that the seal of each pipe fitting is correct. Use a soapy
solution, not a flame!
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 In-
formation" chapter).
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
A) The by-pass screw
• If you change from natural gas G20 20 mbar to liquid
gas, fully tighten the by-pass screw in.
• If you change from liquid gas to natural gas G20 20
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
maximum position to the minimum position.
Electrical connection
• Make sure that the rated voltage and type of power
on the rating plate agree with the voltage and the
power of the local power supply.
• Always use a correctly installed shockproof socket.
• Make sure that there is an access to the mains plug
after installation.
• Do not pull the mains cable to disconnect the appli-
ance. Always pull the mains plug.
• There is a risk of fire when the appliance is in con-
nection with an extension cable, an adapter or a mul-
tiple connection. Make sure that the ground connec-
tion agrees with the standards and regulations.
• Do not let the power cable to heat up to a tempera-
ture higher than 90° C.
Make sure that you connect the blue neutral cable to the
terminal with a letter "N" on it. Connect the brown (or
black) phase cable to the terminal which has a letter "L".
Keep the phase cable connected at all times.
Connection cable
Use only connection cable of type H05V2V2-F T90 or
equivalent type. Make sure that the cable section is ap-
plicable to the voltage and the working temperature. The
yellow/green earth wire must be approximately 2 cm
longer than the brown (or black) phase wire.
