We bought a home with what looks to me like a triple wall 28k from my research on here. The previous owners cut a hole to put a gas line in it. Everyone I call says "I've never seen anything like that and we aren't touching it. Has anyone seen this and if so was there a way to save the insert? Even if it costs the same as a new insert I would rather fix this if possible. for me its a nostalgia thing. We had a similar one growing up. Appreciate any input offered
