Adjustment of the combustion head
At this point of the installation, the combustion head is fixed
to the boiler as shown in Fig. 14. It is therefore especially
easy to adjust, and this adjustment depends only on the max-
imum output of the burner.
Adjustment of the air head is foreseen.
In the diagram of Fig. 16, find the notch at which to adjust
both air and central gas/air.
Air adjustment
Rotate the screw 4) until the notch you have found corre-
sponds with the front surface 5) of the flange.
Important
To facilitate the adjustment, loosen the screw 6)
(Fig. 15), adjust, then block.
CAUTION
Example
RS 35/E BLU, burner output = 270 kW.
From diagram of Fig. 16 you can see that for this output the
air should be adjusted at notch 3, subtracted from the value of
the pressure in the chamber.
Note
If the chamber pressure is equal to 0 mbar, the air adjustment
is made referring to the dotted line of diagram Fig. 16.
Central air adjustment (Fig. 15 - 17)
In case the application needs a particular setup, it is possible to modify the central air delivery using the ring nut 7) up to the notch indi-
cated in diagram Fig. 17. In order to carry out this operation, unscrew the screws 8) and lift up the ring nut 7). At the end, tighten the
screws 8) again.
