ssemblIng the gas traIn
The gas train can be assembled in different ways: (1), (2), (3).
The burner is supplied with the gas train connection facing downward.
If you wish to invert the direction of train entrance to allow the gas train
to be assembled in configuration (1) follow the procedure described
in the section entitled: "Preparation for connection with train turned
upward".
Choose the most rational position for the set-up of the boiler room and
the position in which the gas pipeline arrives.
PREPARATION FOR CONNECTION WITH TRAIN TUR-
NED UPWARDS, ONLY FOR TBG 35
If you wish to orient the entrance train side upward before applying the
burner to the boiler, proceed as follows.
•
Following the instructions detailed in the "Maintenance" para-
graph, extract the mixer assembly and remove the screw (8)
which connects the unit's forward movement rod (14) to the gas
delivery pipe (15).Remove the screw (16) which connects the gas
mixer (17) to the pipe.
•
Turn the bend coupling through 180° (18) and the mixer (17),
in such a way that the inlet gas is turned upwards.Fix again the
mixer and the unit's forward movement rod to the gas delivery
pipe.
•
Now remove the 4 nuts (19), disassemble the flame pipe (20)
from the relative stud bolts, reposition them with the threaded
connection for fixing the gas train upwards.
•
To complete the operation fix the flame pipe to the burner scroll
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 the paragraph "Gas train
assembly".
