3.2 BOILER FIXING
To fit the burner to the boiler it is necessary to carry out the following:
®
Widen, if necessary, the insulating gasket holes (3, fig. 3).
®
Fix the flange (5) to the boiler door (1) using four screws (4) and (if necessary) the nuts (2) interposing
the insulating gasket (3) but keep unloosing one of the two upper screws (4) (see fig. 2).
®
Put on the flange (5) the burner combustion head, tighten the flange with the screws (6) and lock the
loose screw (4).
N.B.: The burner can be fixed with the variable dimension (A) (see fig. 4). Anyway, make sure that the
combustion head crosses completely the boiler door thickness.
