FIREPLACE BURNER APPARATUS

摘要

An improved fireplace assembly is described having a folded sheet metal burner m anifold divided into three regions, being an upper burner, a lower burner and an intermediate co mmunicating 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 as sociated set of simulated logs to create different sizes and shapes of flames, or flame patterns. The flam e patterns generate hot exhaust gases which heat portions of the simulated logs to glow. The burner port s 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.
