Abstract
Gas fire devices are provided that produce a swirling flame by passive means using the kinetic energy of gas exiting through burner ports located in a burner and the kinetic energy of air drawn through louvers or flaps radially positioned on the base of a plenum. Situated above the burner and plenum is a chimney, which surrounds the flame and may be a translucent or transparent material to help observers better see the flame.
