This is proof of our ongoing problem with these burners. In this video the photocell is taken out of its pocket and exposed to the light in the boiler room and is giving positive readings. Then it is put back into its pocket and giving very bad readings leading to fuel faults. I have tested this with 7 photocells and getting much the same with every one.
