I just pulled this from our fireplace. We are upgrading to a sealed air system. This stove insert works and we used it last winter. Made by Northland the insert measures 28" wide x 23" tall x 24" deep. The hearth plate (shown partially attached to support to damper handle) measures 43" wide x 29 1/2" tall. No fan on this model but one could be added to the front of the insert under the ash guard. Very easy to install and remove.
