PREPARATION FOR CONNECTION WITH TRAIN
TURNED UPWARDS
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".
TWO STAGE GAS-FIRED BURNER
It is normally not advisable to connect a burner working on a boiler
for heating water for two-flame working. The burner can also work
for long periods of time with one flame alone. The boiler is insuffi-
ciently loaded and so come out at too low a temperature (less than
dew point) giving rise to the presence of condensation water in
the flue. When the two-flame burner is installed on a boiler for the
production of hot water for heating, it must be connected in such
fig. 1 a way as to work normally with both flames completely stopping,
without changing to the first flame, when the preset temperature
has been reached. For this type of working the thermostat for the
second flame is not installed and a direct connection is made (jum-
per) between the equipment's terminals.
SINGLE STAGE AIR BURNER TBG 45 - 60
ADJUSTMENT SCHEME
To adjust the angle of opening of the air damper, slacken the screw
(1) and turn the hand wheel (2) to bring the index to the desired
position. Subsequently tighten the screw to lock the damper.
Position 0: air damper fully closed.
Position 6: air damper fully open.
