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 schedule.
FUEL LIGHT OIL
FUEL KEROSENE
NOZZLES RECOMMENDED:
Monarch type R - PLP; Delavan type B - W
Steinen type S - SS ; Danfoss type S - B
Angle 60°:
in most cases.
Particularly suitable to avoid flame-detachment during ignition.
45°:
for narrow and long combustion-chamber.
PRESSURE:
8 bar:
the pump leaves the factory set at this value, which is suitable only for kerosene.
10 bar:
maximum pressure for kerosene.
FOR LIGHT OIL INCREASE PRESSURE
12 bar:
in most cases.
14 bar:
improves flame retention; it is therefore suitable for ignitions at low temperatures.
