CORRELATION BETWEEN GAS PRESSURE AND BURNER OUTPUT
To obtain the maximum output, a gas head pressure of 9.3 mbar, relatively to 912T1 model, is measured
(M2, see chapter 3.4, page 5) with the combustion chamber at 0 mbar using gas G20 with a net heat value of

INSTALLATION
3.1 BOILER FIXING
♦ Widen, if necessary, the insulating gasket holes (3) (see 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 pos. 5 the burner combustion head, tighten the flange with the screws pos. 6 and lock
the loose screw pos. 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.
