Adjustment procedure for light oil operation
The light oil flow rate can be adjusted choosing a by-pass nozzle that suits the boiler/utilisation output and setting the delivery and
return pressure values according to the ones quoted on the table below and the diagram on Fig. 20 (as far as reading the pressure
values, see next paragraphs).
