COMBUSTION HEAD SETTING

Installation operations are now at the stage
where the blast tube and sleeve are secured to
the boiler as shown in fig. (A). It is now a very
simple matter to set up the combustion head, as
this depends solely on the MAX output devel-
oped by the burner.
It is therefore essential to establish this value
before proceeding to set up the combustion
head.
Adjustment of the head on the air side is
required.
In diagram (B) find the notch to use for adjusting
the air and the gas, and then proceed as fol-
lows:
Air adjustment (A)
Turn screw 4)(A) until the notch identified is
aligned with the front surface 5)(A) of the flange.

Example
MAX output = 500 Mcal/h.
If we consult diagram (B) we find that for this
output, air must be adjusted using notch 7.5, as
shown in fig. (A).
Once you have finished setting up the head, refit
the burner to the slide bars 3)(C) at approxi-
mately 100 mm from the sleeve 4)(C) - burner
positioned as shown in fig. (C)p.6 - insert the
flame detection probe cable and the ignition
electrode cable and then slide the burner up to
the sleeve so that it is positioned as shown in
fig. (C).
Refit screws 2) on slide bars 3).
Secure the burner to the sleeve by tightening
screw 1).
Reconnect the articulation 6) to the graduated
sector 5).
Important
When fitting the burner on the two slide bars, it
is advisable to gently draw out the high tension
cable and flame detection probe cable until they
