I need some advice. I just got a corn/pellet stove that my dad was getting rid of. I plan on putting it on the first floor of my house. Originally I was going to vent straight out the wall then go up about 6' before terminating. Then I got to reading the owners manual as well as dura vents instructions and they say that exterior pipe should be in an insulated chase. I understand the concept of how condensation in vent pipe for a corn stove is not good, but is it really nessesary to design a chase for the pipe? I don't care if I have to replace the exterior pipe every few years but don't want to have to do it every year. I can run the 6' of vertical on the interior but then the stove has to be further from the wall and I had hoped to put it almost all the way into a corner, not 10" off the back wall. Any advice or personal experience with exterior venting would be greatly appreciated.
