The house we just purchased has a gas fireplace built into the wall. The gas company came out and restarted service and lit all the appliances, including the fireplace pilot. It was still hot out and that pilot was throwing off a good amount of heat so I used the wall shut-off valve to turn it off. That was before I realized there was an off-valve underneath the fireplace. The wall shutoff is a 2 inch circular mount into the wall and the center contains the valve stem control which requires a key that looks like an old roller skate key. Anyway, I'm trying to turn on the gas and instead of the pin turning, the entire mount has broken free from the wall and everything is rotating but I don't think the gas is being turned on because I can't light the pilot. I tried putting a channel locks on the outer mount and tried turning the valve stem but it won't budge.
I was thinking of buying some liquid wrench and spraying that on the valve. Or, am I going to have to break open the wall and replace the valve? The house is only 2 years old so I don't think corrosion would be a factor???
Any ideas?
Thanks,
Joe
