Just to point out a couple of things shown in the video.

First, the relay on the control board in this case is switching Neutral instead of Line, as it was designed to do. This is actually easier on the relay contacts since there won’t be any arcing like you’d have if it were switching Line.

Second, although the gas valve has Line voltage standing at the terminals because of the reverse polarized wall outlet, this does not pose a danger to the appliance… just to the unaware appliance tech!
