Looking into possibly purchasing a pellet stove when they go on sale for next winter and I am trying to figure out where my best layout would be. My house is a 1 1/2 story house and my living room and dining room are open to each other. I know I can run a vent up the west side of my house to above the roof, but I know there is a chimney in the inside wall between the living room and the kitchen that has nothing vented through it. Previously it had furnace vent running through it, but that is vented out the side wall. What is the possibility of venting it through the chimney to the roof? What would be needed? and How could I clean out the pipes that would line the inside of the chimney? Any help would be appreciated!
