PREPARATION FOR CONNECTION WITH TRAIN TURNED
UPWARD
If you wish to orient the entrance train side upward before applying
the burner to the boiler, proceed as follows.
1) Following the instructions in the section entitled "Maintenance",
remove the mixer unit and remove the screw (1) connecting the
forward movement rod (2) of the unit with the gas delivery pipe
(3) passing through the slot (4) in the elbow union (figure 1).
2) Turn the elbow union 180° so that the hole in the gas delivery
pipe is aligned with the slot (4a) in the diametrically opposed
position on the union. Connect up the forward movement rod
(2) and the gas delivery pipe (3) with the screw (1) shown in
figure 1.
3) Now remove the 4 nuts (5) in figure 2, dismantle the flame
tube(6) and, after pulling off the lung (7) from its stud bolts, put
it back in position with the threaded connection for anchoring
the gas train turned upward.
4) To complete the operation, anchor the flame tube (6) and the
lung (7) in place with the 4 nuts (5), then put the mixing unit
back in its housing.
You may now install the burner on the boiler with the valve train
layout shown in configuration 9, described in the section on "As-
sembling the gas train".
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
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.
