One of my secondary burn tubes is taking a crap. Going let fire cool down and put my hearth gloves on to see if I can fix it or if I need to get a replacement.
Upon further inspection a screw is missing now. The tube is fine. So I'll r place the screw. Easy fix
I've replaced 2 screws on mine. One, I lost......the other wouldn't tighten down. I just used zips. The tubes on mine are stainless.
