I feel like I am banging my head against the wall trying to get this pilot light to stay lit so I can start my fireplace. I have a Robert Shaw 7000MVRLC gas valve with a green knob on it that goes from Off, Pilot to on. I was told from a stove shop that in order to light the pilot light you must position the knob on pilot and push and hold inward while pressing the spark igniter. Each time I am able to get the pilot light lit I am unable to turn the knob from pilot to on. It seems the knob has to be pulled out in order to turn it from pilot to on. Each time I do this however the pilot light goes out. I really don't want to call a service person right now but this valve has had issues ever since we've moved in.
