APPLIANCE SPECIFICATIONS
Extraneous light / advanced ignition
During the pre-ventilation and/or pre-starting phase there
shall be no flame signal. Should the signal be present, for
example for advanced ignition due to bad tightness of the
electrovalve, external lighting, short-circuit in the photo-
resistance or in the connecting cable, a breakdown in the
flame signal amplifier, and so on., when the pre-ventilation
and safety time has elapsed, the control-box brings the
burner to the emergency stop and cuts off fuel inflow even
during the safety time.
No flame
If there is no flame at the end of the safety time, the control-
box stops the burner immediately.
No flame during operation
If there is no flame during operation, the control-box cuts
off fuel and automatically repeats a new starting program:
once the "t4" time has elapsed, the starting program is
over.
Every safety stop of less than 1 second switches off voltage
to terminals 3 - 8 - 11: and to terminal 10, it is possible to
provide a remote signal of emergency stop. Resetting of
the control-box is possible after approx. 50 seconds of
emergency stop.

PREPARATIONS FOR START UP
Control that the nozzle applied is suitable for the boiler potentiality. The table shows the delivery rates in kg/h of
light oil with respect to the nozzle size and the pump pressure (normally 12 bar). It should be remembered that 1
kg of light oil is equivalent to approximately 10.200 kcal). Make sure that the return pipe in the tank has no
obstructions, e.g. gate valves, closed plugs etc. Any eventual obstruction would cause a breakage in the sealing
surface situated on the pump shaft. Close the main switch and the boiler thermostats in order to start up the motor
and the ignition transformer. Upon completion of the pre-ventilation time, the solenoid valve is activated. the
electrovalve will cut in and expose the photoresistant cell to a source of light until the burner stops (shut down).
When the pipelines have been filled up (and when fuel has come out of the nozzle), stop the burner and put the
photoresistant cell back in its seat.
NOTE: Should it be necessary to purge air, this can be done by loosening the special fitting which the pump is
provided with (see 8930/1). Do not illuminate the photoresistant cell before the electric valve has cut in
because, in this case, the control box will go to "shut down".
