Fig. 17; proceed as follows:

loosen the screws 3) and remove the cover 1);
 remove the screws 2) from the two guides 5);


 remove the screw 4);


 disconnect the probe and electrode leads, then unthread the
burner completely from the guides 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.
5.8 Combustion head adjustment
At this point of the installation, the combustion head is fixed to the
boiler as shown in Fig. 15.
It is therefore especially easy to adjust, and this adjustment de-
pends only on the maximum output of the burner.
In the diagram (Fig. 18) find the notch at which to adjust both air
and central gas/air.
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.
