Those appear to be Rasmussen fireballs ( http://www.rasmussen.biz/logs/fireballs_main.htm ), but it also appears to be a direct-vent gas fireplace (because of the glass front) and I was not aware of any direct-vents that used fireballs.

I would be very interested to find out what is in the photo above.
