It's not east to tell but I masked off some of the orifices in the fire ring so that the flames wouldn't directly heat the flexible gas line and wouldn't cause an unacceptable updraft beneath the dragon's head. Though the two lines are independently valved I can turn up the pressure to the head only so much in an effort to keep the darned thing lit.
If you're observant you'll have noticed that the surface finish is beginning to show the effects of exposure to the elements, even though there is cover directly overhead. We are, after all, only a mile from the ocean. So this raises another problem to overcome... I don't particularly like the rusted look.
