CHECKING PRIMARY AIR TO THE MAIN BURNERS AND PILOT NOZZLES
All the burners are fitted with an air regulator by means of which the primary air can be varied thanks to an adjustable
bush that can be locked with a screw. In the "Burner Technical Data" table you will find the approximate values for the
"h" parameter (primary air). The flow of primary air must be regulated so there is no detachment of the flame when the
burner is cold or a return of the flame when the burner is hot.
The pilot air is regulated when the appliance is tested and inspected for the gas it is set for.
If you are going to change to a different type of gas, regulate the air by means of the adjusting bush until the flame stops
sputtering and becomes an intense blue colour.

RULES FOR CONVERTING AND INSTALLING FOR OTHER TYPES OF GAS
Our appliances are tested and regulated with liquid gas (see data plate).
The conversion or adaptation to another type of gas must be carried out by a specialised technician. The nozzles for the
various types of gas are supplied in a packet and are marked in hundredths of mm (see "burners" technical data table).
Main nozzles (Fig. C):
Take the rungs off, remove the burners and trays, with a size 12 spanner substitute the nozzles with the appropriate
ones, regulate the primary air (h) (see the "burner" technical data table) unscrewing the securing screw. Once regulated,
tighten the screw, adjust the minimum flame by turning the screw to the right or left until the thermal power reaches 1.5
kW for the 45 kW burner, 1.8 for the 7 kW burner and 2.3 kW for the 10 kW burner.
Caution: If liquid gas is being used the minimum adjustment screw must be locked right down.
