5.5.3 Securing the burner to the boiler

Before fixing the burner to the boiler, through the opening of
the blast tube check that the probe and electrode are cor-
rectly positioned, as in Fig. 10.

Then separate the combustion head from the rest of the
burner by unscrewing the screws 1)(Fig. 9) and 2) and by
removing the fan 4) from the slide bars 3).

Fix the blast tube 6) to the plate (Fig. 9) of the boiler placing
the insulating gasket 5) supplied in between (Fig. 9).

Use the 4 screws, also supplied with the unit, after protecting
the thread with anti-locking product. The seal between
burner and boiler must be airtight.

If the previous control showed that the probe and the elec-
trode are not positioned correctly, remove the two screws
6)(Fig. 12 on page 16), remove the elbow 1)(Fig. 12 on
page 16) and calibrate them.

Finally, put back the fan 4)(Fig. 9) on the slide bars 3), put
back the screws 2) and, with the burner open, proceed to the
adjustment of the combustion head.
