Combustion head adjustment

The air damper servomotor 9)(Fig. 8, on page 12), besides
changing air flow depending on output request, regulates the
combustion head via a lever system.
The choice of the hole to be used is based on diagram (Tab. J)
according to the maximum output required.
The factory regulation corresponds to the minimum output
(coupling position: 0 - Fig. 28).
