  • the surround 58 is shaped in size so that, when a person looks into the firebox 52, a decorative interior surface 64 of the surround 58 around the burner assembly 56 is visible, but side walls and back area of the firebox are blocked from view by the surround 58.
  • the decorative interior surface 64 has a selected pattern or shape that can be any one of a variety of decorative designs. In the illustrated embodiment, the decorative interior surface 64 has a sculpted, shell-type appearance along the quarter-spherical top portion 62, and a smooth arcuate surface on the semi-cylindrical body portion 60.
  • Alternate embodiments can have decorative interior surfaces 64 with designs that simulate bricks, tiles, or a variety of other decorative configurations.
  • Other alternate embodiments can have a surround 58 with a shape different from the illustrated semi-dome shape, while being self-supporting, so the surround stands up in the firebox 52 around the burner assembly 56.
  • the surround 58 is made of a molded ceramic material capable of withstanding the significant heat generated by the burner assembly 56.
  • the surround 58 can be made of a material or composition of materials so the portions of the surround could change in color when a fire is burning in the firebox 52.
  • Other embodiments can provide surrounds 58 made of other fire- resistant, thermally insulative materials.
  • contoured surround 58 is positioned between the burner assembly 56 and the sides and back of the firebox 52.
  • the contoured surround 58 is positioned between the burner assembly 56 and the sides and back of the firebox 52.
  • the surround 58 acts as a heat shield that directs heat forwardly toward the open front portion of the firebox 52.
  • the surround 58 acts as a baffle and has integral exhaust passageways 65 along the side portions that direct the hot exhaust gases from within the area of the surround back into the upper portion of the firebox 52 and to the exhaust flue 41 of the direct vent chimney 40. Accordingly, the surround 58 substantially increases the heat efficiency of the fireplace unit 12, and helps keep the back area of the firebox 52 and the backside of the outer housing 12 at cooler temperatures. These cooler temperatures allow the fireplace unit 12 to be mounted in the receptacle 36 of the furniture unit 14 ( Figure 3) without requiring ah excessive air space for safety purposes.
  • the front of the firebox 52 is open to provide access into the firebox, such as for maintenance of the burner assembly 56.
  • the open front of the firebox 52 is sealably covered by glass 66 or the like that allows for viewing into the firebox when there is a fire burning at the burner assembly 56.
  • a plurality of conventional controls 68 are mounted in the outer housing 50 below the firebox 52 that allows a user to control the burner assembly 56 for operation of the fireplace unit 12.
  • the fireplace unit 12 has a decorative fireplace frame 70 mounted to the front side of the outer housing 50 ( Figure 3) and around the receptacle 36 in the furniture unit 14.
  • the frame 70 has. an arcuate opening 72 positioned adjacent to the glass that allows a person to look into the fireplace unit 12 to see the decorative interior surface 64 of the surround 58, the burner assembly 56, and a fire burning within the firebox 52.
  • the outer housing 50, the surround 58, and the frame 70 have a "portrait" shape, wherein the height dimensions are greater than the width dimensions.
  • the tall, thin fireplace unit 12 provides an aesthetically proportioned shape relative to the selected furniture unit 14 to provide a very handsome fireplace installation 10.
  • the glass 66 covering the open front of the firebox 52 is conventional tempered, high temperature, nonglare glass.
  • the glass 66 has a reflective characteristic, such as a half-silvered coating, that forms a one-way mirror. Accordingly, when there is no fire within the fireplace unit 12 and the light in the room 24 ( Figure 1A) is brighter than the light in the firebox 52, the glass 66 provides a mirror-type reflection when looking at it from outside the firebox (e.g., from the room).
  • the burner assembly 56 is activated and a fire is started within the firebox 52, the light from within the firebox is greater than the light outside of the fireplace unit 12, so that a person can see the fire through the glass instead of seeing the reflection.
  • FIG. 7 is an isometric view of a wall-mounted fireplace installation 74 in accordance with an alternate embodiment of the invention.
  • This installation 74 includes a wall 76 having an enlarged receptacle 78 formed therein that receives the fireplace unit 12.
  • the direct vent chimney 40 is shaped and sized to extend through or within the wall 76 so as to communicate with outside air.
  • the receptacle 78 is positioned well above the floor 80 and is positioned at a location remote from and not surrounded by a conventional mantle of a fireplace.
  • the receptacle 78 and the fireplace unit 12 are positioned so that the middle of the firebox is roughly at eye level for an average adult standing up.
  • the outer housing 50 of the fireplace unit 12 and the glass 66 are generally flush with the wall 76, and the frame 70 is mounted against the wall, thereby providing the decorative frame around the glass 66 and firebox 52, respectively.
  • the glass 66 can be transparent or it can be a one-way mirror, as discussed above.
  • the frame 70 can have an appearance of being a decorative mirror frame.
