The present invention includes a universal combustion chamber preferably shipped from a factory as a separate unit for field installation into a plurality of different fireplace units and includes a top panel and a floor panel connected to sidewall panel to form a complete ready to use gas tight structure. The combustion chamber is fabricated from flat and/or curved panels which are preferably molded from a thick paste slurry of mixed vitreous alumina silicate fibers combined with an aqueous solution of silica binder and fired to form non-porous gas tight panels which are interconnected to form a gas tight combustion chamber. The connecting joints are preferably reinforced by the addition of a high temperature adhesive added to the mating joints. The joints may be further reinforced and/or sealed by mechanical reinforcing at or in the joints. The joints may be eliminated by forming a one piece combustion chamber on forming molds that are designed to be separated from a formed but uncured combustion chamber.

[ What is claimed is:] [1.] A method of making a universal gas combustion chamber for use in a plurality of different prefabricated gas fireplace units, comprising the steps of:mixing refractory ceramic fibers (RCFs) with a solution of inorganic binder to form a thick paste slurry,molding said thick paste slurry into an open box shape fireplace having a plurality of panels comprising a floor panel, at least two side panels and a top panel,removing said open box fireplace from its mold,firing said panels to form a non-porous impact resistant open box of panels of a gas fireplace combustion chamber,assembling stack means, trim means, burner means and said plurality of panels into the gas fireplace combustion chamber to provide said different gas fireplace units, andsealing the joints between said stack means and said trim means, to form unique fireplace units having a reinforced non-porous gas tight gas combustion chamber.
