I have a St. Croix Afton Bay and i need some advice on how to install this at me new house. The former owner of this house had a pot belly stove that he burned out of. I am hoping that i can use the hole in the brick chimney and run my exhaust venting out of that hole. What would i have to do in order for that to be accomplished? Is this going to be a problem with my drafting? Would i have to put a sleave in the chimney flu like people with inserts do? i am really concerned about ash build up in the elbow of the exhaust? Also the current hole in the brick is about 6.5 feet higher then where the exit part of my stove is. If someone could help give me some direction on this i would appreciate it.
