WORKING

4.1 COMBUSTION ADJUSTMENT

In conformity with Efficiency Directive
92/42/EEC the application of the burner on
the boiler, adjustment and testing must be
carried out observing the instruction manual
of the boiler, including verification of the CO
and CO
concentration in the flue gases, their
2
temperatures and the average temperature of
the water in the boiler.
To suit the required appliance output, choose
the proper setting of the combustion head, and
the air damper opening.

COMBUSTION HEAD SETTING

It depends on the output of the burner and is
carried out by rotating clockwise or counter-
clockwise the setting screw (6) until the set-
point marked on the regulating rod (2) is level
with the outside plane of the head assembly
(1) (see fig. 9).
NOTE
The diagram is orientative; to assure a good
working of the burner, we suggest to adjust
the combustion head according to the boiler.
HEAD ASSEMBLY REMOVING
To remove the head assembly, carry out the
following operations:
Remove the head-older assembly (1), after
taking away the screws (7), disconnect the
connections (3 and 5), extract the small tube
(4) and loose the screws (10).
Do not modify the setting position of the brack-
et-elbow during the disassembly.
REASSEMBLY OF THE HEAD SYSTEM
WARNING
During the reassembly of the system,
tighten the screws (7) completely (without
locking them) ; then lock them with a torque
wrench setting of 3 - 4 Nm.
Control that, during the working, there
are not gas losses coming from the
screws.
If casually the pressure test point (13)
looses, fix correctly and be sure that the
hole (F), placed in the external side of the
head-assembly (1) turns towards the
lower part.
