ABSTRACT:
A gaseous lantern ventilator including an outer shell concentrically spaced over an inner metal liner which collects and exhausts the hot gases from the burner assembly through a chimney, the upper end of which is surrounded by an annular opening in the outer shell. The rising hot gases will entrain outside cool air drawn between the shell and liner, thereby cooling the liner and substantially reducing the surface temperature of the outside shell.
