Weil-McLain Chamber Kit Replacement?
I have a 66-68 Weil McLain boiler that recently had a malfunction. Turns out that it wasn't serviced like I thought it had been and was completely clogged. I dismantled the breaching, the front cover, and even swept the chimney out. It is all cleaned out with the exception of the target wall and door blankets. The chamber kit I bought (it's for this exact model) says in the instructions not to remove the target wall or door blankets. But everywhere I'm searching on the web people are removing them and putting the new in. Is there something I'm missing? What's the proper procedure here? Any help would be greatly appreciated.
