Below-grade outside air kit

Is there a nice way to install one? Does anyone have one below grade? How did you do it? Thanks.

I would use 3" PVC pipe outside and take it up the wall, above grade a couple feet at least. Terminate it with a 90 + 45 elbow. Switch to metal on the indoor side.

To be clear, you are in a basement of some sort and want to poke through the concrete wall and into the dirt and then go up in a periscope fashion for air? What a pain in the rear. You would have to dig down on the outside and make for dang certain sure that you don't create a water leak into your home.

I have a long outside air run for my basement install and went up and out the sill plate just above the top concrete block. Also put a 90 elbow outside to keep the outside air from rushing down into the stove, that cold air doesn't need any help flowing down hill.

Heavens no. That would be a pain. I would go up indoors above the sill and out.

Heavens no. That would be a pain. I would go up indoors above the sill and out - similar to what Todd posted.

The question was confusing. It sounds like there is no intention of installing one below grade. You may still want to periscope it a bit outdoors to raise the intake above snow level.
