I am installing a new Jotul F500 and am not sure which stovepipe configuration would be best for me.I don't like the way the chimney sweepings fall into this stove compared to my old Vermont Castings where it just fell into the firebox since I am finatical about keeping my chimney clean and do it often.I was going to vent it out the back with a T and clean-out to simplify the cleaning process.The dealer who seemed quite knowledgable said he does it with a telescoping pipe and just slides it up and vacuums out the creosote.My question is will the telescoping pipe continue to slide up freely after it gets some crud in it?I want to make sure I get it right the first time and not have to dread sweeping my chimney if this is a bad idea
