    Usually, it's double wall pipe or single wall pipe that has horizontal runs, not Class A.

    But to the best of my recollection I think a good many stove manuals state that 4 feet of horizontal, w/ 1/4 inch of rise per foot is about it.

    Is this for the Heatilator chimney replacement? If so, what is the plan? Can you transition to connector pipe for the horizontal?

    No, but thanks for asking. This would be for a separate Class A chimney in another part of the house. I'm trying to decide what would be the best way to go. They both have good points and bad. Weighting the options but at this point I'm leaning towards the heatilator liner.
