Regulation of burners
Regulation of the "MINIMUM" on the burners
To regulate the minimum on the burners carry out the following procedure indicated below:
1) Turn on the burner and put the knob onto position MINIMUM ( small flame ).
2) Remove the knob ( Fig. 9) of the tap which is set for standard pressure. The knob is found on the bar of
the tap itself.
3) Beside the tap bar on the work top, use a small screwdriver that fits the screw (gold) found on the lower
part of the tap (auxiliary, semirapid, rapid Fig. 9) (dual fig.10) and turn the fixing screw to the right or left until
the flame of the burner is regulated in the most suitable way to MINIMUM.
4) Make sure that that the flame does not go out when changing the position quickly from MAXIMUM to the
MINIMUM position.
ATTENTION: The regulation described above can be carried out only with burners using natural gas,
while with burners using propane gas the screw must be fully screwed in, in a clockwise direction.
Adaptation of the pressure regulator for use with different type of gas
The pressure regulator supplied with the appliance is a convertible type pressure regulator for use with
Natural Gas at a nominal outlet pressure of 4” w.c. or LP gas at a nominal outlet pressure of 11” w.c. and it is
pre-arranged from the factory to operate with one of these gas/pressure as indicated in the pre-arranging
labels affixed on the appliance, package and Instruction booklet.
