Hey guys, first off this is the best place for info regarding anything to do with a chimney. I have spent the last week reading up on all kinds of great info. Here is my question. I have decided on a wood insert for my fireplace. My house is about 40 years old and we moved in 2 years ago. I have had about 2 dozen fires lit in the fireplace with no problems at all. We all know how inefficient a open fireplace is so I have my eyes set on a Quadrafire. Now as you can see in the pics I currently have glass doors covering the open of the fireplace. Now after looking at many pics of different inserts I have noticed almost no one's fireplace looks like mine. My firebox is about 8 inches of my hearth, most pics I have seen the firebox sits flush with the hearth. I was wondering is this going to cause a problem when I put my insert in? Will it need some kind of support under the front of it? I live in 2300 sq ft tri level house, our fireplace is on the outside wall of the family room which sits on the lower part of the house. Thanks so much.
