To open the boiler casing:
1. Undo the screws "1" (see fig. 47).

After any operation involving opening the boiler, care-
fully check the correct refitting of the front panel and
its seal.
Proceed in reverse order to refit the front panel. Make sure it is correctly hooked to the upper fa-
stenings and is correctly positioned at the sides. Once the screw "1" is tightened, the head must
not be below the lower reference fold (see fig. 48).
