<p>The invention relates to improvements in fireplace appliances, and in particular to a device for reducing the amount of lost heat from fireplace appliances, such as convector boxes, inset gas fires or inset live effect fires. A convector box comprises an outer casing which surrounds an inner casing, the inner casing forming a combustion chamber in which gaseous fuel is to be combusted, the outer casing and inner casing each having a window aligned so that heat from the combustion chamber can pass outwardly, the space between the outer and inner castings forming a duct having an inlet through which air is drawn due to convection from outside the convector box, the air passing outwardly again, after heating, through a first outlet and the smoke and other combustion products passing through a second outlet wherein the second outlet is provided with a modifying plate which modifies the airflow through the second outlet. <IMAGE></p> |
