REMOVING THE BLAST TUBE
The control of the detector current shall be carried out by plugging a microampe-
rometer with full scale at 1000 µA (D.C.) in series with the UV-cell. If the detec-
tor current is too low verify the connection between phase and neutral of the bur-
ner and the grounding of the burner itself. Minimum required detector current is
200 µA.
