Abstract
Burner assemblies including panels (e.g., transparent panels) supported in a substantially parallel, closely-spaced relationship and gaskets and spacers sealing the space between the panels to form a perimeter seal and to define a plenum between the first and second panels with an inlet into the plenum and an outlet out of the plenum.
Claims21
A gas burner assembly comprising:
- a first sheet having an inner face and an outer face, the first sheet extending a vertical height between a top edge and a bottom edge and extending a horizontal length between a first side edge and a second side edge opposite the first side edge, the first sheet being formed of an at least partially transparent material to form a central viewing window;
- a second sheet having an inner face and an outer face, the second sheet extending a vertical height between a top edge and a bottom edge and extending a horizontal length between a first side edge and a second side edge opposite the first side edge;
- the first and second sheets being secured relative to one another such that the first and second sheets are separated by a gap that defines a substantially thin manifold between the inner faces of the first and second sheets, wherein an outlet from the substantially thin manifold is formed along the top edge of the first sheet, and wherein the outer faces of the first and second sheets form externally-facing surfaces of the gas burner assembly, such that the gas burner assembly includes a single substantially thin manifold along a plane perpendicular to the horizontal length of the first sheet and the horizontal length of the second sheet;
- a conduit in communication with the substantially thin manifold, the conduit being adapted for connection to a source of gas;
- and
- a spacing member located adjacent the first side edge of the first sheet and the first side edge of the second sheet and adjacent the inner faces of the first sheet and the second sheet, wherein the spacing member has a horizontal length that is less than the horizontal length of the first sheet.

A gas burner assembly comprising:
- a first sheet having an inner face and an outer face, the first sheet extending a vertical height between a bottom edge and a top edge;
- a second sheet having an inner face and an outer face, the second sheet extending between a bottom edge and a top edge, the first sheet and the second sheet partially defining an upper manifold having an outlet formed along the top edge of the first sheet, the first sheet being formed of an at least partially transparent material to form a viewing window, the viewing window forming an externally facing surface of the gas burner assembly;
- a lateral frame member located proximate to the bottom edge of the first sheet;
- a first vertical frame member located proximate to a first end of the second sheet;
- a second vertical frame member located proximate to a second end of the second sheet opposite the first edge of the second sheet, wherein outer surfaces of the lateral frame member, first vertical frame member, and second vertical frame member form externally facing surfaces of the gas burner assembly that frame the viewing window;
- a sealing element located between the outer face of the first sheet and the inner face of the lateral frame member, the sealing element defining a boundary of a lower manifold located below the upper manifold;
- and
- a conduit adapted for connection to a source of gas, the conduit adapted to transmit gas from the source of gas to the lower manifold, such that the gas contacts the inner surface of the first sheet adjacent the bottom edge of the first sheet.

A gas burner assembly comprising:
- a first sheet having an inner face and an outer face, the first sheet extending a vertical height between a top edge and a bottom edge and extending a longitudinal length between a first side edge and a second side edge opposite the first side edge, the first sheet being formed of an at least partially transparent material to form a central viewing window;
- a second sheet having an inner face and an outer face, the second sheet extending a vertical height between a top edge and a bottom edge and extending a longitudinal length between a first side edge and a second side edge opposite the first side edge;
- the first and second sheets being secured relative to one another such that the first and second sheets are separated by a gap that defines a substantially thin manifold between the inner faces of the first and second sheets, wherein an outlet from the substantially thin manifold is formed along the top edge of the first sheet;
- a lateral framing member located along a first side edge of the first sheet;
- an ignitor support member adapted to support an ignitor proximate to the outlet from the substantially thin manifold, wherein the ignitor support member is secured to a side of the lateral framing member;
- and
- a conduit in communication with the substantially thin manifold, the conduit being adapted for connection to a source of gas.
