Hello all,
Grateful to have found this resource as it's hard to come by a good chimney person in my area and I'd like to avoid spending more than I have to on hardware or burning my house down. I'm somewhat new to chimneys so I may get some of the terminology wrong, but I'm relatively handy so I feel confident in doing the job myself with some guidance.
My partner and I decided to remove the stand alone fireplace that the house was built with (it barely put out heat and took up the entire room) and replace it with a wood stove.

We decided on the Drolet Alto. We want to place it somewhat close to the wall, so we're going to use double wall pipe up to the ceiling. Here's where it gets tricky. The flue of the old fire place was 8 inch single wall inside of a 12 inch chimney that when to the roof, past the 2nd story via and enclosed housing. I'd like to connect the 6" double wall stove pipe to the 8" just above the ceiling to avoid the expense of replacing all of the 8" pipe.

There's a 15 degree support box in the rafters that I plan to remove and then the pipe runs straight up from there. I can run the stove pipe straight up and maintain 6" from the wall.
Since the Vortex products seem to be sold out, my plan is use Duravent DVL from the wood stove up to the ceiling, then to install a (broken link removed to https://www.northlineexpress.com/6-duratech-round-ceiling-support-box-6dt-rcs-7062.html). Since the ceiling support is 12inch diameter at the top, I'll connect the old 12" chimney to it to close it off. Then I'll use a slip increaser to connect the 6 inch outlet of the support box to the existing 8" pipe.
Please let me know if this is a reasonable plan. Thanks for reading and your responses are greatly appreciated!
