Venting a Harman P 68-3 90-degree angles?

[paula]

Hello,
I'm looking for advice to "reinstall" a Harman P 68 in my new-to-me home (originally purchased in 2010-but works great). We are planning to install it in the basement with floor vents to help heat the open concept living area directly above the stove. The question is ... Can we use 3 x 90-degree elbows (two with clean outs-one inside and one outside)? I attach a schematic below. I'd appreciate any advice or experience!

I have a P43 professionally installed and certified in the basement with exactly that configuration using 4 inch Excelpellet

Just put a clean out T outside before the last vertical rise it’ll make cleaning a bit easier

If you can go with 3" for the OAK, that would be better, and try for 4 inch vent.
