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
the same time the two gas valves
open (Vs safety valve and Vl 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 shutdown within the safety time. In case of gas lack or a
major pressure drop, the minimum air pressure switch shuts down the burner.

CALCULATING THE BURNER CAPACITY
To calculate the burner's capacity in kW, proceed as follows: Check the gas flow rate (in liters)
on the counter and the time of the reading in seconds.
Proceed with the calculation using the following formula:
