Securing the burner to the boiler
Separate the combustion head from the rest of the burner, as in
Fig. 17; proceed as follows:
loosen the screws 3) and remove the cover 1);
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) to the boiler plate, interposing the supplied
insulating gasket 8).
Use the 4 screws supplied, with a tightening torque of 35 ÷
40 Nm, after protecting their thread with anti-seize products.

Combustion head adjustment
At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 15.
Its adjustment is therefore particularly easy, which depends sole-
ly on the maximum output of the burner. This value must be set
before adjusting the combustion head.
Find the air adjustment notch on the diagram (Fig. 18).
Air adjustment
Rotate the screw 4)(Fig. 19) until the notch you have found cor-
responds with the front surface 5) of the flange.
Provide an adequate lifting system of the burner.
WARNING
The seal between burner and boiler must be air-
tight; after the start-up, check there is no leakage
of flue gases into the external environment.
