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 OTHER TYPES OF GAS
Our appliances are tested and regulated for liquid gas.
The conversion or adaptation to another type of gas must be carried out by a specialized technician. The nozzles
for the various types of gas are in a packet supplied with the appliance and are marked in hundredths of mm (see
the technical data table).
SUBSTITUTING THE NOZZLE IN THE COUP DE FEU BURNER
Remove the panel and with a suitable spanner substitute the nozzle with another, suitable one.
Adjust the minimum flame by turning the by-pass screw either to the right or to the left until heat output reaches 4 kW.
The primary air of the all plate burner does not need adjusting.
Attention:
If liquid gas is used, the minimum flame adjustment screw must be screwed right down.
