CHECKING THE PRIMARY AIR OF THE MAIN BURNERS

All the burners are equipped with an air regulator which allows variation of the primary air flow by means of an
adjustable bush which can be blocked in the desired position with a screw. Approximate values for parameter "h"
(primary air) (see pag.3 , fig.3) are given in the Technical Specifications Table. The primary air flow must be regulated
to prevent separation of the flame from a burner when it is cold, or a flashback when it is hot.

PROVISIONS FOR TRANSFORMATION AND INSTALLATION FOR OTHER TYPES
All of our appliances are inspected and set for liquid gas (see the data plate on the lower right-hand front ).
Any transformation or adaptation to other types of gas must be carried out only by a skilled technician. Nozzles for the
various types of gas are contained in the small bag supplied and are marked in hundredths of mm (see Specification
table).
Remove the pot-stands, the burners and the trays, and with a suitable spanner substitute the nozzles with the correct
ones. Adjust the primary air flow (h) by loosening the blocking screw and the corresponding nut (see the Technical
Specifications Table). After making the adjustment, replace the screw and nut, and adjust the minimum flame by
turning screw to the left or right until reaching a thermal power value of 1,2 kW for 3,5 kW burners and 1,8 kW for 5,5
kW burners.
Note: For operation with liquid gas, the minimum flame regulating screw must be tightly blocked.
To substitute the oven gas nozzle, proceed as follows:
• Remove the bottom plate of the oven;
• Remove both burner screws, and unhook the burner and pull it out.
• Substitute the nozzle using an appropriate spanner (see the Technical Specifications Table).
• Attach the burner again.
• Adjust the air regulating bush to the corresponding value in the Technical Specifications Table by
loosening the blocking screw and its nut). Regulate the minimum flame by turning screw to the right or left
