I have a neghbor who installed some old school potbelly type stove in his house/shack has an old brick chimney and was a bit concerned with its integrity so he went down to home depot and bought a few sticks of double wall gas vent pipe. He said cuz it was cheaper and it performs beautifully. Is this not horribly dangerous. i know it will work but... I guess i just dont know what to say. I know im trying to sip from a fire hose but I just thought you guys would have a field day with this. Input???
