I have an older Jotul model 118 wood stove which I was given. It appears to be in pretty good shape except that the two side plates are cracked and warped, and I would assume that I need to replace them. I have checked prices, and as I'm sure you know, they are quite expensive. I am wondering if I could replace the side plates with firebrick and refractory cement? Would that give the stove enough protection? Would the stove still function properly? Any help would be appreciated.
