1ST PHASE - PRE-WASHING:
At the burner starting, the light-oil, sucked by the pump (pos.2), is cleaned by the filter (pos.1) and sent to the return
pipe through the by pass regulator (pos.3).
2ND PHASE - 1ST STAGE IGNITION:
After about 15secs. of pre-washing, the valve V1 opens, the light-oil comes out atomized by the nozzle (1ST) and it is
ignited by the voltaic arc generated by the ignition transformer. The pump light-oil excess delivery is by-passed on the
return pipe through the pressure regulator (pos.3).
SAFETY TIME:
After about 5-10 secs. from excitation of the 1st stage valve V1, if the light-oil does not ignite, the burner stops (lock).
3RD PHASE - 2ND STAGE IGNITION:
After about 5-10 secs. from the igniton of the 1st stage, the 2nd stage valve V2 gets excited and the light-oil is sent to
the 2nd nozzle (2ND) and at the same time to the jack (pos.4) which causes the opening of the 2nd stage air shutter.
