welcome to the forum! we are certainly happy to have other live the dream with us.
your question is worded to confusingly for me to know what you mean (as you can see even Rob's head is doing a double take trying to answer you well)
Please re-write your question and explain in detail what your intention for each pipe to be for (flu gases, heating duct, flu pipe to go through interior of second floor with hopes of obtaining radiant heat of it, pipe out first floor intentioned to only go to height of second floor, etc,etc,etc.)??? some of these things are very bad/illegal, some are quite OK if done correctly... we need to be able to comprehend the question better.
EDIT: I see your using the term "vent" loosely...(better to use the term "Flu Pipe" when talking about the part that goes to chimney, your other so called "vent" may be a plenum or a top coal load door, etc... draft control is generally below the firebed. can you take some photo's of the stove? (this would help more than ANYTHING). Your stove could be an antique which sometimes has some really funky "vents", flappers, flippers, doors, etc. or it could be a stoker which is a whole other animal all together... we need make and model or photo's please
