Sometimes, the deciding factor in choosing a fireplace insert can be which model(s) will fit into the fireplace. This column gives you the minimum fireplace dimensions each insert needs, and is sorted by how tall (T) the opening must be, as that is usually the critical measurement. The measurements listed allow a couple of inches above the insert to enable connection to the liner or direct connect plate. |
