MANUAL HEAD GAS PRESSURE ADJUSTMENT
DEVICE
For the correct operation of the proportional valves throughout
the entire modulation range, during the initial phase of adjusting
the burner it is necessary to change the opening angle of the gas
throttle shown in the diagram by altering head gas pressure.
Per effettuare la regolazione, allentare la vite (1) e ruotare il volan-
tino (2) riferendosi alle tacche numerate. Position the desired mark
in correspondence to the index (3), then tighten the screw again.
Position 0: gas throttle completely closed
Position 9: gas throttle completely open
Choose the best opening angle depending on the modulation
maximum thermal output, following that represented in the diagram
as a rough guide.

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" paragraph,
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".
