WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with EN 267 the application of the burner on
the boiler, adjustment and testing must be carried out
observing the instruction manual of the boiler, including ver-
ification 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, fit
the nozzle then adjust the pump pressure and the air
adjustment, in accordance with the following schedule.
The values shown in the table are measured on a CEN boil-
er (as per EN 267), if they refer to 12.5% CO
2
at sea level
(1013 hPA) and with light oil and room temperature of 20°C, and combustion chamber pressure of 0 mbar.
WARNING:
Combustion air is drawn in from outside, meaning there may be notable changes in temperature, which can affect
the percentage of CO
2
. You are advised to adjust CO
2
in accordance with the graph featured. E.g.: outside air
temperature 20 °C, adjust CO
2
to 12% (± 0.2%).
