Customer Question

replaced the thermopile on my gas fireplace. the tech that was here the other day said I needed a thermopile and gas valve and wanted an additional $850 after I paid him $130. Needless to say, I went and bought a thermopile for $40 and now the pilot stays lit but burner does not ignite when I turn on the wall switch. My question is this. There is a black wire that is not connected to anything. I am not sure that he either forgot to re-wire it or that is a wire for a blower (which we don't have). Should this wire be attached to a lead on the gas valve? I don't see how the valve get energized.
