I ordered two of these for two different homes and was amazed how easy they were to assemble.   There was a minimum of parts and every piece would "line up" perfectly in the assembly process.  (One important note to remember is to initially loosely "tighten" the pieces.  When the unit is assembled, then go back and completely tighten each piece.)   I am also impressed with the amount of heat blown into the rooms.   These fireplaces are simple and attractive additions which add much charm and coziness to the overall appearance of the guest rooms.  The “slim” profile is a definite asset.
