Regular 8" black double wall pipe is 16 years old. It is straight about 20' long up to a cathedral ceiling where it connects to triple wall through the roof.
It's connected to a small Napoleon free standing stove. Mainly burn seasoned oak. Temp with a magnetic thermometer 12" above stove averages 300-400 degree's
sometimes 500. I know that is probably low since it doesn't have a probe. I clean the pipe with a brush from the bottom every other year and their is very little build up
in the pipe. It seems to be hot enough where condensation is not an issue. Anyone have a guess when I should think about replacing the pipe? Any good way to tell?
