In a continual attempt to use what I have rather than buy new stuff, I have a little puzzle.
I have a simple
cast iron box-type stove with a 6" diameter hole at the top.
I have a batch (3 3ft sections) of 8" triple wall chimney for outside the house.
I can get all I need of 6" single wall for inside the house.
QUESTION: does anyone think I'll run into trouble with my draft if I have about 9 feet of 6" that then flares out to maybe 9 feet of 8" pipe?
that is, it's going from a good run of smaller tube to a good run of fatter tube. all straight line, no turns.
