   I don't have a definitive answer, but the idea of having more then one source venting into the same pipe allows the exhaust of one source to travel into the output of the other source which does not seem like a good thing. I'll be interested to hear what others have to say.

   O, I forgot to ask. I would like to know how you determine the minimum pipe diameter to use. I'm hoping there is website that explains how size an exhaust pipe.

   thanks

   It's never a good idea to mix a fan and a gravity vent.

   Don't know of any code that would allow it.  And like Dan says, BAD idea.

   Thanks to everyone who replied... Yeah, I guess I should go with "plan A" and vent horizontally out the exterior for my range...

   Your question is not detailed enough.

   You keep using the word CHIMNEY, but a chimney is not used to vent anything. It is the flues in the chimney are are used for the path for the gases.

   If this had a furnace in the basement and a stove in the kitchen then it should have multiple flues. But even if that is the case then there is no guarantee that it was done right.

   If this is the case it will have multiple holes in the top of the chimney.

   If this flue is separate from the one with the double wall pipe then you can use it to vent. But you would not want to just discharge the van into the flue. Rather use the flue as a chase to run a vent pipe to the top and the appropriate termination.

   Actually you could do that in the same flue as with the other pipe, but I doubt that is is big enough.
