Should I line 8" triple wall with 6"?? inquiring minds want to know

My stove has a 6" output, that I run up to a 8" adapter into the ceiling support box with 8" tipple wall. I dont have draft issues, but I also have only ever been able to close down the primary air 80% or so, any further and she dies, no matter the temp outside.

Anyone think that this would be advantageous?
It wouldn't take too much work/cost to do this and drop a 6" liner inside the 8"

I am just looking to tweak things because I cant leave well enough alone..

 

When I first got my Oslo it was connected to 25' of uninsulated 8" ss liner.
Perfomance was ok to good.
The next year I dropped a 6" liner inside the 8".
Performance was better.

The difference wasn't earth shattering but it was noticeable.

Good luck.

 

Guilty as well.

 

12' of 6" installed inside the 8" class A triple wall. Beautiful day to be up on the roof here in SE Michigan. Finishing up the back lawn and the going to go for a good long run with the pup. We will see how it works tonight

 

That'll work.
I'm guessing that cattle dog will run circles around you.
