I'm clear on how the rectification within the valve connector block in the presence of a flame results in a small dc voltage ( the ac voltage which is present across electode and the pilot finds it easier to flow one way as there is a greater mass of metal in the pilot). The resulting dc small signal is amplified by the transistors on the board and then switches the relay to operate the main valve. In fact despite your comments it may be that my grasp of the theory exceeds your own.
