CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT To obtain the maximum output, it is necessary to have 4.6 mbar measured on the pipe coupling, with the combustion chamber at 0 mbar and gas G20 - Pci = 10 kWh/Nm (8,570 kcal/Nm D5136 15,000 20,000...
ELECTRICAL WIRING WARNING: Do not swap neutral and phase over, follow the diagram shown ~ 50Hz 230V carefully and carry out a good earth connection. The section of the conductors must be at least 1 mm . (Unless requested otherwise by local standards and legislation).
COMBUSTION HEAD ADJUSTMENT Loosen the screw (A), move the elbow (B) so that the rear plate of the coupling (C) coincides with the set point. Tighten the screw (A). Example: The burner is installed in a 40 kW boiler. Considering efficiency of 90% the burner must supply around 44 kW.
COMBUSTION ADJUSTMENT In conformity with Efficiency Directive 92/42/EEC, the application of the burner on the boiler, adjust- ment and testing must be carried out by observing the instruction manual of the boiler, including verification of the CO and CO concentration in the flue gases, their temperatures and the average temperature of the water in the boiler.
AIR PRESSURE SWITCH The air pressure switch is set after all other adjustments have been made. Begin with the switch at the lowest setting. With the burner function at the required power, turn the knob slowly in a clockwise di- rection until burner lockout.

CONTINUOUS PURGING FUNCTION, (only for applications in which this is provided for) Continuous purging is an operation that maintains the air purging regardless of whether there is a request for the burner to turn on or not. From the moment it is set, the motor keeps running whether the limit thermostat (TL) has not been switched (burner off), or when the burner is blocked.

VISUAL DIAGNOSTICS CONTROL BOX The control box supplied features a diagnostics function through which any causes of malfunctioning can be identified (indicator: RED LED signal). To use this function, you must press and hold the reset button for at least 3 seconds once it has entered the safety condition (lockout).
FAULTS / SOLUTIONS Here below you can find some causes and the possible solutions for a series of problems that could cause a failure to start or the poor operation of the burner. A fault in the operation usually switches on the lockout lamp, situated inside the reset button of the control box (7, fig.

WARNINGS AND SAFETY The dimension of the boiler’s combustion chamber must respond to specific values, in order to guarantee a combustion with the lowest polluting emissions rate. You are therefore advised to consult the Technical Assistance Department before choosing this type of burner for the combination with a boiler.
