Usually they don't want single wall venting run in attics or crawl spaces. Our
code
sais you need 1" clearance from B vent to combustibles, and 6" clearance from C
vent to
combustibles. Normally you you would see a short piece of cvent and then a
cvent to
bvent adapter. I would run as much of the vent connector in bvent as you can.

Or you could call ftwhd...hahah so helpful He doesn't know a flue from the hole
in his
ass!

HAHA
