After getting the vertical adjustment dialed in I loaded about 6 bags of lava rock onto the grill, put some thin sheet metal around the perimeter and fired it up. Seemed to work without too much trouble but the flames did not look quite as I expected them to.

So I waited until sunset and then fired up the nostrils. Looks a bit more intimidating, don't you think? But still, I'm not happy with the base flames. Burn efficiency is too good. Plus, I found that the flexible gas line that runs inside to the head was actually getting cooked by the fire ring flames! Not a good thing.

Another look in the daylight. Too hard to see the flames but you can feel the heat!
