Use only the suitable box wrench provided for this operation to remove the nozzle, taking care to not damage the elec-
trodes. Fit the new nozzle with the same care. N ot e: Always check the position of electrodes after having replaced the
nozzle (see illustration). A wrong position could cause ignition troubles.
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.
