This is really a neat product, has flame that looks almost real but you know it isn't.  I view it more as casting a cool ambiance of flickering light...that you can adjust the color.  You don't have to run the heat either.  Controls with a remote! We actually recessed it in the wall.  Used a register diffuser to direct the heat thru a black painted screen.   We also allowed unit to intake air through the sides of the same screen.  Framed it with 2x4 and sheet rock then used grout-less stone, with a piece of barn beam as the mantel.  hanging a flat screen tv above the mantel that's recessed back so no issue with the heat from the fireplace.  Highly recommend this!
