there is a discharge of diesel from the nut / connection of

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.
