Trouble getting metal flue installed

Installed some handsome Isokerns: two custom see throughs with class A 16” ID, flue by Durachimney (Earthcore didn’t have 16”ID available). Flue runs are 30’ each.

The trouble is getting someone comfortable installing the Duravent product on Isokern. Compounding a bit is that the plans call for a mechanical top mount damper by KW which would be interlocked with the EIS/IPI (gas logs will be installed even though it’s masonry and class A).

Now getting some static that the products aren’t by the same manufacturer (although Isokern engineers already wrote extensive instructions)…

Who should I call on?

Idk and good luck. I personally refuse to do anything that involves dampers/fans/gas logs together. Too many issues. If ur doing logs I cant imagine why u would be doing that and not a direct vent unit. I’m assuming the venting components are over 10k per chimney in just pipe. That whole set up just looks sketchy af.
