Inspect the unit completely before installing. The packaging is weak and may get damaged/dented in shipment.
Also if you are looking for screws/bolts etc. they are in the box with the glass in it. Wear gloves, as the glass pieces/dust can cling to your skin. 
Love the unit and the clear glass - looks like ice and fire! 
The shipping may damage the unit. Also shipping will crush a few glass pieces, causing glass dust. I had the edge dented a bit in the shipping. See picture. I decided to keep the unit even though the unit was damaged in shipping. Overall - very good unit. We enjoy the flames at night!
