The temperature control to fire the burner is an electronic control with a dial.
Drain the lines and the tank and disconnect them from the boiler. Can't see how the lines were connected from here. If there's a steam line to the tank cap that off on the boiler side. Unless the lines leak water, don't cap them on the boiler side. Cap them on the feedwater side.
There are some older wiring diagrams in the PDF downloads at
