BURNER CONNECTION TO THE BOILER
ASSEMBLING THE HEAD UNIT
- Position insulating seal 3 on the sleeve, placing cord 2 between
the flange and the seal.
- Loosen screws "6", adjust the position of the connection
flange "5" so that the combustion head penetrates the fur-
nace up to the length recommended by the generator manu-
facturer.
- Fasten the burner 4 to the boiler 1 by means of the stud bolts,
washers and the nuts provided 7.
N.B. Completely seal the space between the burner sleeve and
the hole in the refractory material inside the boiler door with
suitable material.
ASSEMBLING THE GAS TRAIN
There are different possible assembly configurations for the gas
train according to the different installation requirements, as shown
in the diagram (8, 8a, 9). The burners are supplied with gas train
connections facing downwards. Due to the air-gas command devices
and their relative fixed connections there are only two solutions for
TBG 35P, (8 e 8a).
Only the TBG 35 can provide for the assembly of the gas train ac-
cording to configuration 9.
PREPARATION FOR CONNECTION WITH TRAIN
TURNED UPWARDS (TBG 35)
If you wish to turn the train entrance upwards, before applying the
burner to the boiler, follow the subsequent procedure.
1) Following the instructions detailed in the "Maintenance" para-
graph, extract the mixer assembly and remove the screw (1)
which connect the unit's forward movement rod (2) to the gas
delivery pipe (3).
(3) Remove the screw (5) which connects the gas mixer (6) to the
pipe (figure 1).
2) Turn the bend coupling through 180° (4) and the mixer (6), in
such a way that the inlet gas is turned upwards (figure 1). Again
fix the mixer and the unit's forward movement rod to the gas
delivery pipe.
3) Now remove the 4 nuts (7) in figure 2, disassemble the flame
pipe (8) from the relative stud bolts, reposition them with the
threaded connection for fixing the gas train upwards.
4) To complete the operation fix the flame pipe to the scroll burner
and finally reposition the mixing unit in the relative housing.
At this point it is possible to install the burner in the boiler with the
valve train as shown in configuration 9 illustrated in paragraph "Gas
train assembly".
