ENGLISH
The switch on stage is thus repeated and, if the flame ignites again
normally, the burner starts working again normally, if not (if the flame is
irregular or fails to light completely) the equipment goes automatically
into lock-out (LED 5 comes on).
If the program is interrupted (due to a power supply failure, manual
action or the intervention of the thermostat, etc.) during the pre-wash
stage, the programmer returns to its starting position and will automati-
cally repeat the whole of the burner ignition sequence.
CAUTION / WARNINGS
The selection of the nozzles in function of the desired total flow
rate (2 nozzles in operation) must be made accounting for the
flow rate values that correspond to 12 bar16 bar the diesel
operating pressure. Replacing the nozzles it is possible to
change considerably the ratio between first and second stage.

perating deScription
The burner's hydraulic circuit is equipped with a solenoid valve and a
by-pass adjusting valve for a smooth vibration-less ignition when ope-
rating with liquid fuel.
A part of diesel is thus drained only during the first 3-4 seconds of ope-
ration of the burner. Once ignition is complete, the by-pass solenoid
valve closes and the rate corresponds to the first stage value.
Use a screwdriver on the by-pass adjusting screw located inside the
cap (16), (screw in to increase the pressure) so as to obtain only du-
ring the ignition stage a pressure of approx. 9 bars, measured by con-
necting a pressure gauge in position (17).
Correct if necessary the corresponding amount of combustion air by
acting on the electronic equipment settings.
