ABSTRACT:
Method and gas burner assembly for producing among the arrangement of non-combustible logs, and essentially yellow flame pattern with substantially low levels of carbon monoxide production. In general, method hereof employs a gas burner assembly having one or more burner each having a plurality of gas jets. The burner assembly is disposed between the combustion chamber of fireplace enclosure which contains a predetermined volume of combustion chamber air which is continuously provided from outside of the combustion chamber. Non-combustible fireplace logs are arranged above the gas burner assembly so as to provide one or more flow paths between the burner and adjacent logs, for allowing free flow of combustion chamber air through the flow paths and about the burners. Flow of gas is provided through the burners so that the gas flows out of the gas jets and mixes with the combustion chamber air about the jets of the burner. Combustion chamber air flowing through the flow paths and about the burner is concentrated so that the flame pattern has essentially a yellow color, and the logs above the burners are maintained at a sufficient temperature so that combustion gases flowing out of the fireplace exhaust have substantially low levels of carbon monoxide. In the preferred embodiment, an H-shaped burner is used in practicing the method of the present invention.
