I have a problem with the above boiler in that the main burner will not
light.
It seems that it is not flame sensing as the fan is rinning the pilot
lights but the spark gap (SG1) on the control board flashes in a
sequence that appears as if it is still trying to light the pilot.

The boiler's GC No. is: 4160166.

How does this boiler sense that the pilot has lit? Is it the electrode
that senses that the pilot is lit?

Any help appreciated.
