ABSTRACT:
A gas burner for a fireplace. The burner comprises a burner housing having a grid of openings that are formed from heat resistant material. The housing has a first burner assembly and a second burner assembly arranged therein in a side-by-side relationship, each burner assembly having a chamber with a perforated gas distribution plate. The gas distribution plate is located adjacent the grid. Each of the burner assemblies has a gas mixing area with an inlet for primary air and combustible gas, and air flow controllers e.g. primary air shutters, for controlling the ratio of primary air to gas in the first burner assembly lower than the ratio in the second burner assembly.
