WORKING

4.1 COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive 92/42/EEC the application of the burner on the boiler, adjustment and
testing must be carried out 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.
To suit the required appliance output, choose the proper nozzle and adjust the pump pressure, the setting of
the combustion head, and the air damper opening in accordance with the following table.
The values shown in the table are measured on a CEN boiler (as per EN 267).
They refer to 12.5% CO 2 at sea level and with gas oil and room temperature of 20 °C.

AIR DAMPER AND PUMP PRESSURE SETTING

1 st STAGE ADJUSTMENT
ADJUSTMENT OF AIR DAMPER, (fig. 13)
Unloosen the nut (1), turn the screw (2) until the indicator (3) reaches
the position desired.
Then lock the nut (1).
ADJUSTMENT OF PUMP PRESSURE, (fig. 14)
The pump comes with a factory setting of 9 bar.
Where necessary, reset pressure by turning screw (7).
The pressure gauge must be mounted in place of cap (8).
2 nd STAGE ADJUSTMENT
ADJUSTMENT OF AIR DAMPER, (fig. 13)
Unloosen the nut (4), turn the screw (5) until the
indicator (3) reaches the position desired.
Then lock the nut (4).
When burner shuts down the air damper auto-
matically closes till a max. chimney depressure
of 0.5 mbar.
ADJUSTMENT OF PUMP PRESSURE, (fig. 14)
The pump comes with a factory setting of 14 bar.
Where necessary, reset pressure by turning
screw (9).
The pressure gauge must be mounted in place
of cap (8).
