Ok, Yes I am a Chick, No I probably dont know what I am talking about... I live in Minnesota, It gets real cold here in the winter.... My question is, can you vent a indoor wood furnace out the same vent pipe as a natural gas furnace? I am trying to cut down on my fuel costs... Anyone please let me know either way. Do I need to add another vent pipe going outside or can I double up with my existing one?
