I am thinking about relocating my Harmon PC45 to an interior wall. I have a clear path straight up through the attic space out the roof. I do not want to make any holes in the floor or walls.

Is there a stove pipe that includes the intake air so I can continue to use outside air for combustion? I seem to remember a type of pipe that allowed the intake air to be taken from the liner but that might have been for a gas fireplace insert.

Any ideas?

The downside of your idea is that the cold incoming air will cool off the exh so the solids in it won't make it out of the pipe and the pipe will plug faster.
Bixby had used that type of pipe and in a short pipe system it works great but problems rose if you had the stove in the basement requiring a long pipe run.
One solution might be drawing air from the basement? or garage
I know several people with older homes that just use room air and get by fine. I wouldn't recommend it but if you think back when there was old fuel oil stoves heating homes we all survived without outside air for stoves.
One plumber showed me a trick he used which was a pipe going outside from the basement. It ended up in a 5 gallon bucket. He claimed the cold air would stay in that bucket until the furnace ran then it would replace the air being drawn into the furnace for combustion.

Selkirk 4DT was rated for corn stoves. Not sure if it still is. I would not recommend it as the intake air cools the exhaust gas to the point of comdensation and the acids in the exhaust eat holes through the stainless. I used it originally but in 3 months the pipe was rotted out.
