5.11 Combustion head setting
In addition to varying air flow depending on the output requested,
the air gate valve servomotor 4)(Fig. 4) 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).
The choice of the hole (1-2-3) to be used is decided on the basis
of diagram (Fig. 18) against the required maximum output.
Setting is pre-arranged in the plant for the maximum run (hole 3,
Fig. 16).
If combustion requirements require you to move spacer
1)(Fig. 17) onto the 1st or 2nd hole of the gear and, at the same
time, the hinge is on the right, you need to fit the spacers
4)(Fig. 17) supplied with the burner.
Proceed as follows (Fig. 17):

unscrew nuts 2), remove tie rod 3);

unscrew spacer 1) and position it on the hole you want;

screw the spacers (4) onto spacer (1) and screw (5) respec-
tively;

refit the tie rod and nuts.
