You know the fake brick looking metal things in a St Croix? There are 3, one on the back, one on each side in the firebox. I was banging on them with a rubber mallet and the side ones fell out. So I took the opportunity to clean them and brush all the stuff off the firebox behind them. My question is, do they have to be in there? Because I can't figure out how to get them back in and it would be so much easier to clean the stove without them in there lol.
