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
2
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 schedule.
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 light oil and room temperature of 20°C.
PUMP PRESSURE
: 12 bar, the pump leaves the factory set at this value.
