Abstract
An improved fireplace assembly is described having a folded sheet metal burner manifold divided into three regions, being an upper burner, a lower burner and an intermediate communicating riser. This single manifold chamber is provided with two separate gas inlets, each of which may deliver a different primary air to fuel mix suitable for use with an array of burner ports and an associated set of simulated logs to create different sizes and shapes of flames, or flame patterns. The flame patterns generate hot exhaust gases which heat portions of the simulated logs to glow. The burner ports used in the assembly to generate suitably attractive flame displays may include large or non-circular apertures or slots having local reinforcement to resist deformation of those apertures.
