Kungur, Hand FIRED--FIRED I say
Your plan will work fine my friend & yes black pipe will do the job nicely.
Are you going to put in a MPD?? Over hot pipe should not be a problem I can put my hand on the pipe of my Hitzer above the MPD( 3' up from stove body), all winter. What make stove ya lookin at?? I'd advise putting a cap on top, and yes, I know you knew that.
