Smaller pipe in stove jack opening

[mrbillbrown]

Has anybody used a 2.5” stove pipe in a 3” stove jack opening and had issues?

I’ve got a circular to slight oval shaped hole cut in my stove jack that was originally cut for a 3” pipe. Looking to use a stove with a 2.5” pipe and wondering if I’m gonna have issues with the extra void space. Yes, I’m now aware I should’ve cut and X instead of the hole. Lesson learned. Lol

You should be fine, I’d just be careful with any wind, or excess pipe length. The play could prematurely wear the stove jack.

Thanks for chiming in. Think I’ll give it a shot.

Not sure if you want to try, but winnerwell has a 2.5 double wide pipe that would make it 4 inches I think but give a little more heat protection. Can cut it bigger then. Just an idea.
