position.
• Turning the screw that limits the piston travel distance in the
case of models with hydraulic jack (see 0002935420) or use air
adjustment cam air of the 2
nd
flame for servo motor models (see
0002935210) and set the air shutter opening in the 2
nd
stage
at a position considered suitable for the desired supply of fuel.
• Now connect the burner again; it will start and automatically
switch to the 2
nd
flame according to the present program.
• With the burner operating with the 2
nd
flame, adjust the amount
of air necessary to ensure an efficient combustion with the screw
mentioned under item 7. Combustion test should be made using
appropriate instruments. Make the regulation so as to obtain a
certain amount of carbon dioxide (CO
2
) in the smoke, varying
from min. 10% to max. 13% with a smoke number not exceeding
2 (Bacharach scale).
!
When first switching on the burner, shut downs may be
experienced during the passing from 1
st
- 2
nd
flame due to
the presence of air in the jack circuit. Slightly loosen the nut
blocking the jack pipe, carry out a few operating cycles until
there is a discharge of diesel from the nut / connection of
the jack. Tighten the nut when the operation is finished.
CHECKS
After starting up the burner, check the safety devices (photoresistance,
block, thermostats).
• 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).
• 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:
- Start up the burner.
- 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.
- 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.
• 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.
