In addition to varying air flow depending on the output requested,
the air gate valve servomotor 4) (Fig. 5) by means of a lifting as-
sembly - varies the setting of the combustion head.
This system allows an optimal setting even at a minimum firing
rate.
For the same servomotor rotation, combustion head opening
can be varied by moving the tie rod onto holes 1-2-3) (Fig. 16).
