I took these gas logs out of my fireplace and replaced them with another set. The gas valve was messed up so I never saw them work but I suppose there isn't much to go wrong with gas logs? ha! It looks like they're Comfort Flame 24 inch vented logs (according to the owner's manual below)? The "gravel" underneath is also included. They're 65,000 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. 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 its of poor quality. I have a better one on an older phone of them installed that I can show you if you come to look at them.
