the same time the two gas valves open (Vs safety valve and Vl Low flame working valve). The total safety, in case of
missed ignition or casual burner's flame-out, is granted by a ionisation probe which cuts-in and sets the burner shut-
down within the safety time. In case of gas lack or a major pressure drop, the minimum air pressure switch shuts down
the burner.

The control box starts the burner
fan, to carry out the prepurging
of the combustion chamber, and
cheks the vent air pressure throu-
gh the air pressure switch. At the
end of prepurging, the ignition
transformer cuts-in and generates
a spark between the electrodes. At
