”PAB” VERSION GAS BURNERS GAS TRAIN INSTALLATION AND SETTING INSTRUCTIONS
Fix the gas train to burner body by means of the 4 screws of the flange, pay attention to set correctly the gasket ( O-
ring ). Connect electrically the gas train with the 2 connectors of the valve (black) and gas pressure switch(gray).
Switch on the burner (it has already been tested in the factory, so it is pre set on average values) and verify the tightness
of gas train connections made during installation.
Act as follows to adapt the burner output to the boiler.
REGULATING THE COMBUSTION OF THE TWO-STAGE BURNER (PAB version)
Follow the sequence of operations:
Maximum power regulation:
1) position the air valve in the fully open setting (pos. 4).
(for particularly low power only, if the reduction of air is not sufficient with the head in position 1, reduce the opening
of the air valve).
2) dose the air by moving the combustion head (figure) to suit the power required (as shown in figure).
3) dose the gas by regulating the gas ramp (see figure in the ramp manual).
Low flame setting:
1) after regulating the maximum power and determining the working pressure of the gas in the head, position the valve
on the low flame setting, 1.5, and dose the gas using the regulation screw on the butterfly valve of the gas. (figure).
2) if the minimum charge obtained in this way is too low for the heat generator, increase the opening of the air valve,
adjusting the flow of gas using the butterfly valve of the gas to obtain the minimum appropriate power.
REGULATING THE COMBUSTION OF THE ONE-STAGE BURNER (P version)
Follow the instructions for maximum power regulation of the PAB version.
