Securing the burner to the boiler
Prepare a suitable lifting system to secure the
burner to the boiler.
Put on the flange 1)(Fig. 7) the screw 2) and two nuts 3).
It is necessary that the insulating gasket 5)(Fig. 10) is placed
between the boiler door and the burner flange.
If necessary, the insulating gasket can be modified as shown
in Fig. 8.
Fix the flange 1) to the boiler door 4) using screws 2) and (if
necessary) the nuts 3) interposing the insulating gasket 5).
Verify that the installed burner is lightly leaned towards the
button (Fig. 9).
Insert the burner tube through the flange and push to ensure
full insertion. With the burner collar fully inserted into the
flange the O-ring will form a seal. Fix the securing nut 3)
onto the bolt 2)(Fig. 7).
The seal between burner and boiler must be
airtight.
