It does fit snug. Here is a pic of how the inner pipe hits the weld on the collar.
A drawband collar around the "exposed" part of the adapter would take care of any "issues" in my mind (but I'd probably run it as is as I said earlier) although I'm sure that would not satisfy some inspectors. The UL guys would have little geek heart attacks when they seen that clamp!
That information was direct from Bryan the CEO of Olympia that manufacturers ventis. I find it a bit absurd that you think an inch of single wall exposed at the hottest part of the pipe would not effect clearances
I agree completely.A drawband collar around the "exposed" part of the adapter would take care of any "issues" in my mind (but I'd probably run it as is as I said earlier) although I'm sure that would not satisfy some inspectors.

Would that clearance be part of the stove clearance spec? The flue collar being part of the stove. The lab testing doesn't specify a particular type of double-wall required.
That would be a question for Englander. All I know is what Olympia told me which was the double wall has to run from the stove top to the chimney with no gaps.
I don't know if the collar counts as single wall or not. As I said that is a question for Englander. But I do know what I was told by Olympia. And I know making it fit all the way down is extremely easy so why not just do it and be on the safe side? I honestly don't know if it says it in their instructions or not. I took their training class on their ventis line when it was introduced and that is what I have gone by unless a new product is introduced.
It would be helpful to the OP to describe the options and recommend how to in this case.
I did above. I either trim down the inner wall so it fits down or run just the pipe with no adapter if that fits better. Every stove is different I have also had to hammer out the inner wall to make it fit tight in the collar.
