I am looking to purchase a St Croix stove from a dealer in my town who just recently started selling them. I am looking at either the Hastings pellet stove or the Greenfield pellet/corn stove. The dealer does not have the answers for my questions, and I have to know this information before I buy. I am hopeful that someone knows on this forum My biggest concern is how I plan to vent the stove once I buy it: I have a chimney that is lined with a stainless steel flue (I believe it is rather large in diameter-- somewhere around 8 inches across)-- I do NOT have a fireplace. Currently I have a wood stove in the basement that is connected to this flue. I will only use that wood stove if the power goes out and I cannot use my pellet stove. My woodstove is old-- at least 40 years (so maybe not air tight?). I was going to have an access cut into my flue on the first floor so I can place my pellet stove in front of the chimeny and use the existing flue. I would run a vent pipe up from my pellet stove about 3 feet or so to elbow into the flue. I was going to run a 5 inch in diameter painted stainless tube for the pellet stove vent. I was planning on transitioning from the 3 inch to the 5 inch vent somewhere behind the stove. I am getting conflicting advice on whether or not I can use my flue in the chimney since the pellet stove is forced air. I am hearing things about "draw" issues and advice on making sure my woodstove is shut tightly so I do not have smoke in my house from the pellet stove. Mostly people have been telling me to contact the someone else to get the real information since no one seems to have the right info over here. Also, I have heard conflicting advice about whether or not I need to run a tube into the chimney cavity (not in the flue) for a fresh air supply-- do I need this? My house is 100 years old-- old windows, new blown-in foam insulation-- does that affect a need for a cold air supply? Please help! I would really appreciate it. I know most people vent these out the walls of their houses, but I would like to use the chimney if possible. Thank you!
