Combustion Adjustment - Riello G5 444T50 Operation Manual

COMBUSTION ADJUSTMENT

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 concentration in the flue gases, their temperatures and the average temperature of
2
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.

NOZZLES RECOMMENDED: Monarch type R - NS ; Delavan type W -A - E
Angle: 60° - in most cases.
80° - in case of flame detachment, during ignitions at low temperatures.

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.
