I am looking to remove a wood stove that I presently have in my house and replace it with a pellet stove. My question is, will I have to install a stainless steel liner in my existing brick chimney or can I just have my pellet stove vent directly into my chimney. The existing wood stove is in the basement and the house is a two story so the chimney is fairly tall. I had a pellet stove in my previous house but it was direct vented out through the side of the house. In talking to one sales person, they recommend that I not use a liner but then others suggest that I do. What should I do?
