5.8 Combustion head adjustment
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 de-
pends only on the maximum output of the burner.
Two adjustments of the head are foreseen:
–air
–gas
In the diagram (Fig. 17) find the notch at which to adjust both air
and central gas/air.
