The control of the ionisation current shall be carried out by plugging a microamperometer
with full scale at 50 µA (D.C.) in series with the UV-cell. If the ioinisation current is too
low verify the connection between phase and neutral of the burner and the grounding of
the burner itself. Usually, the value of the ionisation current is > 20 µA.
Minimum required ionisation current: 3 µA
