    Do not have code but if closer than 8 feet to wall vent must extend 2 feet above roof.

    Jim, I'm not sure about that. But how close is that flue pipe to the adjacent roof surface? Is that type-B vent or single walled?

    That's single walled pipe. The pipe is almost touching the wood fascia. I have the one inch clearance from the roof sheathing but I dontThink I have one inch from the fascia. I'm also concerned about drafting properly.

    Single Walled pipe clearance is 6 inches. B vent is 1 inch clearance from combustibles.

    That single wall should not be going through the attic. Needs to be type B or L.

    My bad, That is a type B flue, however it is less than 12 inches in diameter. Does the same clearance from horizontal objects apply?
