Abstract: A termination cap for a direct vent appliance. The termination cap comprises an outer housing, an exhaust housing nested within the outer housing and a trim plate. The trim plate has an exhaust gas opening and combustion air openings and is securable to the exhaust body to allow exhaust gas to flow through the exhaust gas opening. At least a portion of the combustion air drawn through the combustion air openings is heated and exits through the top or upper portion of the trim plate to form an air wash along the wall surface within which the cap is mounted.

Abstract: A fireplace with a smart glass panel and use of a smart glass panel in a fireplace are provided. The fireplace comprises a heating mechanism, and a smart glass panel positioned proximate to the heating mechanism. The smart glass panel comprising a transparent pane, where at least a portion of the smart glass panel has optic or thermal transmission properties that may be altered between a first state and a second state.

Abstract: Apparatus for igniting a burner of a barbeque includes a housing, a mesh, an orifice, a pair of conductors and a generator. The housing defines a conduit having an inlet and an outlet spaced apart from the inlet. The mesh occludes the conduit and is positioned adjacent the outlet. The orifice is for receiving combustible gas and communicates with the inlet. The pair of conductors define a gap, the gap being positioned such that the gap is disposed in spaced relation to the mesh and the mesh is disposed intermediate the orifice and the gap. The generator is for producing a spark across the gap.

Abstract: An appliance comprising a firebox, a first air duct and a room air chimney. During operation of the appliance heated room air adjacent to a viewing pane or the screen and heated room air from the first air duct is received within the chimney. The heated air within the chimney rises toward an open upper end causing the chimney to draw additional room air from adjacent to the viewing pane or screen.

Abstract: A fireplace comprises a firebox which has a flue and front, bottom, top, rear and side panels. An outer casing is spaced from and surrounds the firebox. A combustion air plenum is positioned at a point above the bottom of the firebox and is connected to a conduit that communicates with a source external to the room in which the fireplace is situated for supplying combustion air to the fireplace. The firebox has a combustion air entry port in at least one of side panels of the firebox near the bottom of the firebox for supplying combustion air to the interior of the firebox. The combustion air port communicates with the combustion air plenum through a first passage. The flue passes upwardly through the firebox and is adapted to be connected to a second conduit that is in communication with a source external to the room which the fireplace is situated for exhausting the combustion gasses from the fireplace.

Abstract: A fireplace comprises a firebox having a top panel, bottom panel, rear panel and a flue. An outer casing is spaced from and surrounds the firebox. A combustion air feed passage for supplying combustion air to the firebox is provided. A heat exchanger, which is located downstream from the flue for receiving the combustion gases and for transmitting the heat from the combustion gases to air to be heated, is also provided. The fireplace includes a passage for conveying the combustion gases from the flue to a conduit in communication with a source external to the room in which the fireplace is situated for exhausting the combustion gases from the fireplace and a switch for selectively coupling the heat exchanger in series with the passage. The switch is operable between a first position which the flue gases pass through the heat exchanger before being vented to the outside and a second position which the flue gases pass through the passage, bypassing the heat exchanger, and are then vented to the outside.
