Fireplace gas valve questions
I'm renovating and one project I have is to install a log lighter in my fireplace. Currently, there's a plastic-handled gas valve inside the firebox. Before I bought the house, I guess the gas company had come out to cap it. When I had my level 2 chimney inspection done, the guy told me that it wasn't safe to use it as-is. He said to either find the existing gas valve under the flooring or behind the mantel or get a new one installed. So I pulled the mantel off along with the flooring (I'm redoing it anyway), and I can't find the original valve. My questions are:
What can I expect to make this fireplace log lighter ready
Can anybody surmise what the story behind the original gas valve is?
Why is there a plastic gas valve in the firebox?
What is the concrete "box" around the brick? Is that original to the house? Is it possible that the original valve was sealed up underneath that?
