After starting up the burner, check the safety devices (photoresistance,

1) The photocell is the flame control device and so it should trip if
the flame extinguishes during operation (this check should be
made after at least 1 minute from lighting up).
2 The burner should be capable of blocking itself and
remain so when a normal flame does not come on during
start-up cycle and within the preset on control box.
The "lock-out" causes the motor and the burner to stop
immediately and corresponding "lock-out" warning lamp lights
up.To check the function photoresistant-cell and lock-out system
proceed as follows:
a) Start up the burner.
b) After at least one minute, remove the photo-cell from its seat
and pull it out and simulate flame failure by covering the photo-
cell (use a rag to close the window in the photocell support).
The burner flame should go to lock-out.
c) Keep the photo-cell in the dark and the burner will start again,
but the photo-cell does see the light and the burner goes to
lock-out within the time preset by control box. The control
box can be reset only manually by pressing the appropriate
push-button.
3) To check the thermostat efficiency, run the burner until the water
in the boiler reaches a temperature of at least 50 °c and then
turn the thermostat control knob to reduce the temperature until
an opening click is heard and simultaneous stopping of the
burner. The thermostat should trip within a maximum tolerance
of 5 to 10 °C in respect to the control thermometer (boiler
thermometer); if not, change the setting on the thermostat
scale to match that of the thermometer.

Adjustment of 1
1) To increase air supply capacity, turn ring nut C1 anticlockwise;
use the counter wrench on body A of the jack to prevent too
much being exerted on the eyelet of pin H. This action lowers
body A and favours the opening of air shutter F in first stage.
To reduce the flow of air turn ring nut C2 clockwise, also in this case
use the counter wrench on the body of the jack. In this case body
A is raised and favours the closing of air shutter F.
2) After adjustment of the 1
