Danger in Blocking Off Gas Fireplace
I have cheaply-built home, with a cheaply installed 1980's gas fireplace. Like many here, it is very drafty - cold air just seems to flow right through it, and the between the gas panels into my living room. We don't ever use the fireplace (two toddlers in the house, and the glass gets dangerously hot), so my solution was to cut a piece of rigid foam insulation and cover the opening entirely.
So far it works great, but now I'm worried I've created a dangerous situation, blocking the gas line (turned off) behind the foam. Am I overthinking it? The flu is open (doesn't shut).
