4.8 Combustion head setting
In addition to varying air flow depending on the output request-
ed, the air gate valve servomotor 4) (Fig. 5) by means of a lifting
assembly - 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. 14.
The choice of the hole (1-2-3) to be used is decided on the basis
of diagram (Fig. 16) against the required maximum output.
Setting is pre-arranged in the plant for the maximum run (hole 3)
(Fig. 14).
When dealing with boilers featuring a strong back pressure, if air
delivery is insufficient even with the damper fully open, you can
use a different setting to that illustrated in diagram (Fig. 16) do
this by moving the tie rod onto the next highest index, thus in-
creasing the combustion head’s opening and hence air delivery.
If combustion requirements require you to move spacer 1) (Fig.
15) onto the 1
st
or 2
nd
hole of the gear and, at the same time,
the hinge is on the right, you need to fit the spacers 4) (Fig. 15)
supplied with the burner.
Proceed as follows:

first 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,

once done, refit the tie rod and nuts.
