OAK install question?

Im planning on installing my oak to terminate in my stairwell of my walk-out basement. It will exit next to my basement slider. Any thoughts?

In a stair well through the wall to the outside near the slider is fine.

Make sure no "snow" or leaves can cover it up.

Here is a pic.

Yes smokey. I am constantly pulling leaves out of there. Thanks for reply. I plan on terminating outside at 18 inches

Do you have enough room to not cut into any structural supports?

Thats what im working on. I need to determine if the frame for my slider is load bearing or not? My trusses all rest on the poured concrete foundation. I believe the 2 by 4s are just framing around the slider. But i need to be sure.

Structurally, it might be easier to go through the wall on top of the door.

But from a drafting perspective you want the OAK termination as far below the vent termination as possible.
