Piping through floor joist? Is there such thing as an oval stove pipe?

[Diesel]

I'm in a bit of a dillema. I want to install a second pellet stove in my basement, the location in which I want to install it would require the exhaust pipe to go through a single floor joist. Obviously, there are restrictions on the diameter of a hole that can be cut in a floor joist.

Has anybody been faced with this and been able to come up with a solution? Is there such this as an oval pipe, albeit a small length, that I could go from round to oval, then back to round again that would somehow meet the code?

Any information would be greatly appreciated.

Thanks.

Shoot a few pictures and maybe someone will have an alternate route for the venting.

What's your spacing between joists? Why not put an elbow in and move the pipe over?

This would be a corner setup, the other corner has a deck above it. The clearance between the deck joists and what the pipe, and the pipe to the ground would be is a couple of inches.

The spacing between the joist in question and the foundation is a couple of inches at best.

What about thru the foundation, knock out 1/2 a block.

its been many years since tin knocked , but u can go round to oval but not the other way. i"m sure in the past 40 years there are many adapters for you to chose from now , we did this freehand
