WORKING
4.1 COMBUSTION ADJUSTMENT
In conformity with EN 267 the application of the burner on the boiler, adjustment and testing must be car-
ried out observing the instruction manual of the boiler, including verification of the CO and CO
2
concentra-
tion 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 accord-
ance with the following schedule.
The values shown in the table are measured on a CEN
boiler (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 accor-
dance with the graph featured. E.g.: outside air temperature
20 °C, adjust CO
2
to 12% (± 0.2%).
4.2 NOZZLES RECOMMENDED
Delavan type W;
Hago
type SS;
Steinen
type Q;
Danfoss
type S.
Angle
:
60° - In most cases.
80° - In case of flame detachment, during ignitions at low temperatures.
4.3 PUMP PRESSURE
12 bar: The pump leaves the factory set at this value.
14 bar: Improves flame retention; it is therefore suitable for ignitions at low temperatures.
