I have asked a few questions about a used Quadrafire 7100 I am buying.Going to get some pics of it today I hope. I was wondering, I am putting this in a new construction addition on my house with a basement under it. Can these be installed through the wall or do they install in the room with chimney pipe through the ceiling? Which is better? Think I want it in the room with chimney through ceiling and rock all the way up but just wondering what my options are?
