My Enviro Windsor has a burnpot and removable liner. I think the liner might have a hairline crack in it. It extends from the igniter hole to one of the airholes. It seems to be only on the outside of the liner, I can't exactly indentify it on the inside. If it is a crack, would it affect the performance of the stove? It appears to be burning right, although I am cleaning out the burnpot more often than earlier in the season. I assumed it was because I am running it harder. I don't think that it is stainless steel, so is there a possibility that I can weld it? Happy Holidays to All.
