Hi Ronmuckerheide,

Based on the information you've provided I can't answer your question. Go over to this question - http://checkthishouse.com/qa/544/can-vent-be-merged-with-the-furnace-vent-into-chimney-stack-6#a545 and follow the calculations explained in my answer using parameters from your own installation and Gama tables, or provide me with everything that's required to perform those calculations (as explained when you follow the link).

Let me know if you need help, just click "comment" below.
