These are what's left of the front standoffs that came with the fireplace. They're used to set a specific heat clearance dimension, but they've been cut up and I don't know if I can use them at all. I did call the manufacturer for replacements, but they don't stock them and they would have to be made - which would take 4-6 weeks and then another 7-10 biz days for shipping. I may have to bend some up myself...
