It's not a true N/S loader but the fire box is 16.5 deep. I cut most of my stuff 14-16' so it works either way. The Enerzone 2.3 has the same size firebox and is advertised as a front to back or side to side.I thought the Drolet Escape 1800 was more of a E/W loader. The firebricks only look about 13" deep. Is this different from your stove?
