Someone who knows we are buying an insert has sweetly offered us this one (for free). I am certain it's not EPA certified, but I also have a feeling it may even be "unlisted" and with our close clearances and flush hearth I am certain this would not be a possibility for us even if we were not concerned about the EPA issue. However, I figured since I had the pics I might as well put them up and see if anyone has any ideas. I certainly haven't seen anything that looks much like this so far. I'm guessing it at about 20-25 yrs old maybe? The pics have a very hard ray of sunlight coming in, I am pretty sure that's gold colored trim around the surround.
