Combustion head adjustment

At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 13. It is therefore especially easy to adjust,
and this adjustment depends only on the maximum output of the
burner.
In the diagram (Fig. 17) find the notch at which to adjust both air
and central gas/air.
NOTE:
the diagram (Fig. 17) indicates the optimum adjustment for a
type of boiler according to Fig. 3 on page 9.
