I believe I have everything I need for my install. My set up is 6” out of stove a Clean out T, then 12-15’ of vertical pipe, I have a Ceiling Support at the ceiling and then a pipe support bracket in the attic then Flashing Cone, Storm Collar, and finally the pipe cap, All in 3”. I am looking at (according to standard calcs) 11.5-13’ of total distance that I have to run the pipe from stove exhaust to outside. One area I am a little fuzzy on is sending the pipe through the roof. It is my understanding that I should have a Storm Collar on top of the Flashing cone and then at least 3" of clearance around the pipe and then put high temp sealant around the Storm Collar and the Flashing Cone. Am I missing anything?

If I am reading your post correctly...you are running close to 15 foot of vertical pipe and using 3" diameter pipe? What does your manual say is the max run before you should use 4" diameter pipe?

Sorry I can't answer your roof collar question but I just wanted to make sure you didn't go through all that cost just to end up with a bad venting/draft problem.

My advice is
use 4" if you are 15 feet or over
DO NOT USE the clamp in the support box.
Pain in the ass if you want to lift up or down on the pipe in the future.
Flash and storm collar. Put two screws in the storm collar into the pipe this will do the same thing as clamp in a box.
Seal with RTV or Through the roof sealer. the pipe is NOT that hot and through the roof works great. I think it is rated for 180 deg.
