Hello everybody, relatively new to wood burning, boy I learned a lot this winter. I knew the cat was clogged, after two years I didn't even know there was one . I took it out and all of the ceramic literally fell out in hundreds of pieces, is that normal, was I wrong to lay it down? I can order a replacement but now steel or ceramic? I have a Travis Xtrordinair Hybrid Fyre, any suggestions would be great! Thank you.
