Cleaning and replacing the detection photoresistor
To clean/replace the photoresistive detector, remove it from its slot. To clean the photoresistor, use a clean cloth, not
cleaning sprays.
Check the detection current
To measure the detection current, refer to the diagram in Fig. 12. If
the signal doesn’t suit the suggested value, verify the electric
terminals, the cleaning of the combustion head and the position of
the photoelectric cell and replace it if required.
