Securing the burner to the boiler
Before fixing the burner to the boiler, check
from the opening of the blast tube that the
probe and the electrode are correctly posi-
WARNING tioned, as in Fig. 12.
If, in the previous check, the position of the probe or elec-
trode was not correct, remove the screw 1)(Fig. 13),
extract the inner part 2)(Fig. 13) of the head, and adjust
them.
Do not rotate the probe: leave it as in Fig. 12 since if it is
located too close to the ignition electrode, the control box
amplifier may be damaged.
Separate the combustion head from the rest of the burner,
Fig. 11.
To do this, proceed as follows:
- loosen the 4 screws 3) and remove the hood 1);
- disengage the articulated coupling 7) from the gradu-
ated sector 8);
- remove screws 2) from the two slide bars 5);
- remove the 2 screws 4) and pull the burner back on
slide bars 5) by about 100 mm;
- disconnect the probe and electrode cables, then slide
off the burner completely from the slide bars.
Once this operation has been carried out, fix the flange
11)(Fig. 11) to the boiler plate, interposing the insulating
gasket 9)(Fig. 11) supplied.
Use the 4 screws supplied, with a tightening torque of 35 -
40 Nm, after protecting their thread with anti-seize prod-
ucts.
The seal between burner and boiler must be
airtight. After the start-up (see Ch. 5.3),
check there is no leakage of flue gases into
the external environment.
