Once we spent 4 hours filling the gaps and removing the glue left by the sticker they put on the front of the glass it turned out to be beautiful fireplace.
The first photo above shows the glue covered with warm soapy water. That's what they recommended I use when I called Realflame. FYI, that doesn't work very well. You will need to use essential oils and a straight edge blade to get the glue off.  To fill the gaps that was on both sides we used white DAP Alex plus caulking. That worked very well. 
So it's a beautiful fireplace, but if you're not into a DIY project purchase a different unit.
