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 observing the instruction manual of the boiler, including verifica-
tion 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, 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 light oil and room temperature of 20 °C.
RECOMMENDED NOZZLES:
Monarch type R - NS;
Delavan type W - A - E;
Steinen type H - Q;
Danfoss type H.
Angle
:
60°
:
in most cases.
80° :
in case of flame detachment, during ignitions at low temper-
atures.
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.
COMBUSTION HEAD SETTING
This is done when fitting the nozzle, with the blast
tube removed. It depends on the output of the
burner and is carried out by rotating the regulating
rod, till the terminal plane of the blast tube is level
with the set-point, as indicated in the table.
In the figure 5, the combustion head is set for an
output of 0.75 GPH at 12 bar, while the shutter is
level with set-point
2.5
, as required by the above
table.
