    Is the Thermostat wire... touching?? when you put on T-T make sure it's not touching or that will cause this

    Do you have a 24 volt gas valve or a powerpile self generating valve?

    If you have a 24 volt valve wire valve to B1 and B3 and insert jumper between TP and Z.

    If you have a powerpile valve wire B1 and B2 to powerpile valve and no jumper between TP and Z.

    Give us the number of the gas valve and the make?

    I had posted this in the other section you inquired in.
