Replacing a wood stove that had an 8 inch flue with a new one having a 6 inch flue.
Discovered that the original 8 inch triple wall chimney pipe is not rated for a wood stove even though it has been used for that purpose for many years.
Not really wanting to have the expense and re-construction required to replace the pipe I'm wondering if I could simply push 6 inch double or single wall stove pipe the full length up into the old pipe.
Seems to me this would give the equivalent of 4 or 5 wall pipe.
Anything wrong with this idea?
