I have power coming in, power going out to the circulator but no power going to the burner control when there is a call for heat?

    Is this a brand new install...

    or is it a control that has stopped working after a period of time??

    The relays are separate and one could be working, but not the other...

    You can choose to do what you want, but you cannot choose the consequences.

    The L8148B is

    a isolated burner circuit B1/B2 for use with a powerpile system there is no power at B1 and B2 until the pilot is lit and the pilot generator provides 750 Millivolts.

    So the question what is the status of the pilot?
