Fireplace shuts off pilot when switched on
I moved into a house that has a gas fireplace and I'm having trouble lighting it. I'm able to get the pilot light lit. It burns fine and stays lit. I turn the control knob to on. When I switch the on/off switch to 'On' however, there is a click and the pilot light clicks off. The same thing happens if I put the switch to 'RS' and turn the wall switch to on. It's like there is some safety switch that is being triggered, but I can't figure out what it is.
My fireplace is a Majco(acquired by Majestic) G800piLP
