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 

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.

 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 0002900910). 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”.
