I am just double checking before I order my vent pipe, my plan is to run the vent pipe into my existing wood stove 6" Metalbestos pipe via a 3" Selkirk adapter. Is there anything that I need to know before doing this. My wood stove chimney system is a up then out and then up again system. I am assumng that since this is a forced venting sytem that it shouldn't be a problem. Any important insights are welcomed.
