Gas log apparatus utilizes a burner in which a gas/air mixture is distributed to burner ports by a flat horizontal plenum chamber supported by a grate. The ports are rectangular, and formed in lateral ridges in the plenum chamber beneath and to either side of a laterally extending artificial log supported above the plenum chamber. The log is the middle of three logs arranged one behind the other and successively stepped upwardly, the middle and rear logs being supported by cantilevered extensions from the rear of the grate. The ports have varying width and spacing, which together with their sharply angled configuration, contributes to a lifelike appearance of the flames without causing excessive carbon monoxide emission.

An apparatus simulating natural log fire, comprising a grate, at least two artificial logs supported in the grate so as to extend laterally thereof with a laterally extending vertical opening between them, and a burner assembly supported by the grate, the burner assembly including a gas nozzle, air induction means associated with the nozzle to produce a fuel/air mixture, and a plenum chamber receiving the mixture and defining a laterally extending row of polygonal burner ports directed upwardly beneath said vertical opening, the ports being formed at the apex of an inverted V-shaped ridge in an upper wall of the plenum chamber, by openings extending vertically through said upper wall, the ports being of varying lateral extent and spacing, and having sharply angled vertices.
