Correct position of electrodes and combustion head
To ensure a good ignition, respect the measures in Fig. 54 - Fig. 55.
Single stage burners (mod. LO280-LO400) and Double stage burners (mod. LO280)
Check the detection current
See the diagram in Fig. 56 to measure the detection current. If the signal doesn’t suit the suggested value, check the electric terminal,
the cleaning of the combustion head and the position of the photoelectric cell; replace it if necessary.
