I see the Lopi Freedom Insert has a tapered firebox. It's wider in front and narrows as it goes back, just like many fireplaces it has to fit into. This allows it to have a large 2.9 cubic foot firebox which can accommodate long 24" logs in the front but still only need the fireplace to be 21.25" wide in the back. I really like this feature because I think the larger firebox means I can load it up with more wood and the large width in front means I can fit those odd-sized longer pieces you sometimes get but the tapering allows it to fit into my medium sized fireplace.
Are there any other inserts you can think of that also use a tapered firebox?
