In this particular installation, we were dealing with a very small firebox opening. With this firebox no longer considered safe for open fires, these homeowners were left with a drafty and empty opening which was devoid of any practical use.
The clients were also having difficulty maintaining a comfortable temperature in this livingroom. The room was consistently 3 to 4º lower than the rest of the house partially due to the drafts from the chimney, along with other factors such as the position of the room in the home (front of house and near front entry).
