GAS TRANSFORMATIONS AND ADJUSTMENTS
• REPLACING THE NOZZLES
If the equipment is adjusted for a type of gas that is diff erent from the one available, it is necessary to replace the
burner nozzles.
The choice of the nozzles to replace must be made according to the table of the “technical characteristics” as enclosed.
Act as follows:
• Remove the racks and burners.
• By means of a straight spanner L, unscrew the nozzle U (fi g.8) and substitute it with the corresponding one.
• Tighten the nozzle strongly.
• ADJUSTING THE BURNERS
The lowest fl ame point must always be properly adjusted and the fl ame must remain on even if there is an abrupt shift
from the maximum to the minimum position.
If this is not so, it is necessary to adjust the lowest fl ame point as follows:
• start the burner up;
• turn the tap up to the minimum position (small fl ame);
• remove the knob from the tap rod;
• introduce a fl at-tip screwdriver in the hole F of the tap (fi g.9) and turn the by-pass screw up to a proper
adjustment of the lowest fl ame point.
As regards G30 gas burners, the by-pass screw must be tightened completely.
MAINTENANCE
• REPLACING THE POWER SUPPLY CABLE

or H05RR-F, complying with the regulations in force.
The connection to the terminal board must be eff ected as shown in fi g. 10 - 10/A:
