Installation and Warnings – Continued
Gas Connection
Make sure that the appliance is adjusted for the gas type available in your area (see the label under the
appliance). Follow the instructions indicated in the chapter “gas transformations and adjustments” for the
possible adaptation to different gases.
The appliance must be connected to the gas system by means of still metal pipes or flexible steel pipes
having continuous walls, in compliance with the regulations in force in your area. Some models are
equipped with cylindrical A and conical B connectors for gas supply (fig. 7).
WARNING:
The connection must not stress the gas clamp.
Electric connection
The connection to the electricity supply must be carried out by qualified personnel and in conformity with
the regulations in force in your area.
The voltage of the electric system must correspond to the value indicated in the label under the appliance.
Make sure that the electric system is provided with an effective ground connection in compliance with the
regulations and provisions of the law.
Grounding is compulsory.
GAS TRANSFORMATIONS AND ADJUSTMENTS
Replacing the nozzles
If the equipment is adjusted for a type of gas that is different from the original, it is necessary to replace the
burner nozzles as well. The nozzles used to replace the original must be in accordance with the table of
the technical characteristics enclosed.
To remove the racks and burners by means of a straight spanner ‘L’, unscrew the nozzle ‘U’
(Fig. 8) and substitute it with the corresponding one and tighten the nozzle.
Adjusting the burners
The flame should always stay alight when the burner is switched on, even if there is an abrupt shift from
the maximum to minimum flame position. If the flame does not stay alight, adjust it as follows
:
•
Start the burner
•
Turn the tap up to the minimum position (small flame)
•
Remove the knob from the tap rod
•
Using a flat-tip screwdriver ‘C’ into the hole ‘F’ of the tap (fig.9) turn the by-pass screw up.
MAINTENANCE
Lubricating the taps
In the case of tap hardening, it is necessary to disassemble the tap and grease it.
•
Unscrew the two screws that lock the head flange of the tap.
•
Lift the gas adjusting cone and carefully clean it with gasoline or diluent.
•
Spread a little high-temperature grease on it, making sure that the gas holes are not obstructed.
•
Reassemble all of the parts with care.
Replacing the power supply cable
If the power supply cable needs to be replaced, it is necessary to use a cable with a section of 3 x
0.75mm2, type H05VV-F or H05RR-F, complying with the regulations in force.
NOTE:
The connection to the terminal board must be effected as shown in fig. 10 - 10A:
Brown cable L (phase)
Blue cable N (neutral)
Green-yellow cable (ground)
