Good news. I found an honest and reasonable contractor in central new york to install my chimney. But I do have a question of those of you with experience. When he ripped out my old fireplace he noticed it was connected to outside air. He said it would be a good oppourtunity to attach an outside air kit to the new stove I am getting. So my question is: is it worth it? What kind of benefits could I potentially see? Are there any drawbacks? Are they adjustable, for instance, if I did not like the way it burned with it, could I close it?
