Fully modulating burners
To adjust the fully-modulating burners, use the CMF switch on the burner control panel (see next picture), instead of the TAB thermo-
stat as described on the previous paragraphs about the progressive burners. Go on adjusting the burner as described before, paying
attention to use the CMF switch intead of
TAB .
The CMF position sets the oprating stages: to drive the burner to the high-flame stage, set CMF=1; to drive it to the low-flame stage, set
CMF=2.
To move the adjusting cam set CMF=1 or 2 and then CMF=0.
CMF = 0 stop at the current position
CMF = 1 high flame operation
CMF = 2 low flame operation
CMF = 3 automatic operation
Adjusting heavy oil flow rate
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 chart below and the diagram on Fig. 22 (as far as reading the pressure
values, see next paragraphs).
