And if not for what to do yourself and recover the pipe used by the gas boiler?
it all depends on what is this smoke pipe: a wood boiler needs a big and solid pipe ... if the pipe is only suitable for the gas boiler it may not be good
in general I prefer to keep the old boiler in place, it can always help out
fashion is all stainless steel smoke ducts: it doesn't cost more to make an entirely new chimney than to use an old stainless steel tube
