I do all my other work on the house would feel comfortable doing work my self with and inspection at finish does any one know if where the chimney ends in the attic can liner be connected to triple wall to finish it out of the roof or can the liner be used
I'm not quite following - are you saying that you have chimneys that end in the attic someplace? What were they used for? Are they old chimneys that got "chopped off" during some previous "home improvement" project?
If they are old chimneys that got chopped, I'd want to have some really serious inspection done on them before trying to reuse them, as you want to make sure that they are still in decent shape, without any problematic damage from the previous demo work...
Depending on what you find, and possibly some pricing, the three choices I would see are
1. Demo the existing chimney the rest of the way to the ground, and then go up through the space with Class A prefab chimney (What I think you were calling triple-wall, but there is some Class A that is only double wall with solid packed insulation between the layers)
2. Build the existing chimney back up to code required height, and probably install an insulated liner
3. Come up with some hardware to make the transition at the end of the existing chimney, and go up with Class A, and down with an insulated liner - I'm not sure what hardware exists to do this, but far as I know it would be a legitimate option as long as you did all the proper clearances to combustibles and so forth. You CAN'T use the chimney liner to go up, as it is only approved for use inside a chimney, or possibly in a short length to connect to an appliance in a fireplace or similar environment.
Also, I have noticed you've gotten several threads going on similar subjects - I'm going to start merging them together so as to keep the discussion in one place and reduce confusion... IMHO it's a good idea to keep at least major phases of a single project inside a single thread, it avoids duplicate replies, etc...
