Abstract
An enclosed gas fireplace which efficiently transfers heat from a combustion chamber to surrounding air chambers and to air flow conduits which pass through a flue gas offtake. The fireplace has an outer shell that remains relatively cool, so that the fireplace can be installed in a framed sheetrock or wood enclosure without the need for utilizing the special masonry work or masonry chimney normally required for a fireplace. In addition, the invention provides a special burner arrangement to enhance the aesthetic quality of the fire and which provides a clean-burning gas flame to meet modern emission standards.
