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 positioned,
as in Fig. 14.
If, in the previous check, the position of the probe or electrode was not correct, remove the screw 1)(Fig. 15), extract the inner part
2)(Fig. 15) of the head, and adjust them.
Do not rotate the probe: leave it as in Fig. 14. If it is located too close to the ignition electrode, the control box amplifier may be damaged.

remove the screws 2) from the two guides 5);
disconnect the plug 14), unscrew the grommet 15);
remove the screw 4);
pull back the burner on the guides 5) by about 100 mm;
disconnect the probe and electrode cables and remove the
entire burner from the guides, after having removed the split pin
from the guide 5).
Fix the flange 9)(Fig. 13) to the boiler plate, interposing the supplied insulating gasket 8)(Fig. 13).
Use the 4 screws supplied, with a tightening torque of 35 - 40 Nm, after protecting their thread with anti-seize products.
The seal between burner and boiler must be airtight. After the start-up (see Ch. 5.8), check there is no leakage of flue gases into the
external environment.
