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".
