I removed the gas logs from my fireplace and replaced them with another set. The gas valve was messed up so I never got to see them work but I suppose there's not a whole lot to go wrong with gas logs? ha! It looks like they're Comfort Flame 24" vented logs (according to the owner's manual I found below)? The fake "gravel" underneath is also included. They're 65K BTU and would be great if you had a fireplace and wanted emergency heat in the winter for power outages and don't feel like carrying wood? ha. Or, I suppose, if you had/added a metal chimney in a workshop or garage, then I suppose it could be used for that? I thought that I already had a good picture of them while installed and didn't take a pic of them before they were removed but they look like most other log sets. I do have one pic of them that I'm attaching here but I apologize for its poor quality. I have a better one on an old phone that I can show you if you come to look at them though.
