Plumbing for outside air

[snowplow]

Hi guys, I am doing a remodel on a home we just got. I have a BEAUTIFUL old '76 Grampa Fisher. I am nowhere near installing it yet, but would like to plumb it for outside combustion air and reburn capability. I am a new guy to this so correct me if I am way off...

So- I am cutting my floor slab and installing some plumbing right by where the stove will go. I was wondering if I could pour in my inlet pipe to hook up to when I get around to it. Does anyone see any reason not to do this? How big of pipe? Material (conduit, threaded gas pipe etc)?

Any help would be appreciated!

I am not sure but I don't think you can do a new install of a non epa approved stove in wa.

I ran 3" drain pipe with a dryer vent cover on the outside with screening to keep the critters out.
