VC intrepid ii collar mate to 6” Tee

[StevieRnR]

Hey All!

I am swapping in a VC intrepid ii into my setup due to it being UL listed.. previously had a fisher baby bear.

6” liner down masonry chimney. T at the bottom, rear outlet on both stoves, but with the VC it looks like the outlet is closer to 6.5” and I can’t quite get the 6” T over it. If I get it inside the diameter, it looks like it’s kinda hangin by a half inch.. you can see in the second pic how little the room there is to screw it in. Might be able to get it in another half inch.. but it’ll be close. You can also see prior holes on how snug the fisher was.

What’s the easiest and best way to properly mate these up?

Thanks!
