:eek: 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? :confused:

You can do whatever you want... but to be safe, no you should not share the flues. It is also against firecodes.
Wood creates creosote and the water from your gas unit will destroy the pipe. Not only that but you can get backdrafting and carbon monoxide into the home.
I would send the wood, double walled pipe through the roof
Your local firemarshall can help with questions also, and inspect the installation so your insurance will cover you in a fire.
