Stove pipe install questions

[Deancamp]

I'm to the point in my project to start running stove pipe up and through a metal roof. My stove flue exits out the back of the stove and I am using a Selkirk double wall Tee fitting at that point. Should I use some type of collar to fasten to the stove? The double wall pipe will be extending up approx 7' where it will change over to a supervent stove pipe before going through the roof. Do I need locking bands at the double wall pipe joints or are the attaching screws enough? I assume there is some type of transition collar for the double wall and supervent pipe? I saw on previous threads it is recommended to use the metal flashing vs silicone. I was thinking a roof support collar as well with framing under it. I cant wrap my head around how to use the metal flashing especially with the roof support. Is there a specific metal flashing? How is the corrugated roof sealed off?
Thanks, Jeff

Terminology here is important. The pipe between the stove and the ceiling support is stove pipe or connector. From that point up it is class A chimney pipe, not stove pipe. Stove pipe can not be used outside of the room envelope. The support box handles the transition between the two, distinct types of flue piping.

Here is a guide for Excel's metal roof flashing
