Each mirrored panel is mounted substantially flush to its wall and has a mirrored surface that can be flat, curved or have a complex shape and can also have a decorative design so as to give a visual appearance of emulating its wall. A mirrored surface can also be used with a fire pit, in which case it will also serve as a wall, and the gas burner of the fire pit can be raised to enhance the effect of using the mirrored surface.Type: ApplicationFiled: December 17, 2007Publication date: July 10, 2008Inventor: Razmik Thomas

Publication number: 20080149094Abstract: A burner base includes a base member, a gas tube and a nozzle. The burner base includes a base, a housing on the base with an opening at a top thereof, an indentation at a junction of the base and the housing, a hollow connection member on the housing, an output tube in the housing and communicated with the indentation. The housing has an output passageway therein, and the base has a gas passageway therein communicated with the indentation. The gas tube is connected to the connection member and communicated with the output passageway. The nozzle is connected to the gas passageway to jet gas to the output tube through the indentation. Gas is provided into the base member through the gas tub and the nozzle respectively and flows out via the output passageway and output tube respectively.Type: ApplicationFiled: February 8, 2007Publication date: June 26, 2008Inventor: Sen-Yu Wu

Patent number: 7322819Abstract: A fireplace including a backlighting system. The backlighting system can be positioned in a back portion of the bottom panel of the fireplace. The backlighting system includes at least one light source to shine light upon the components of the fireplace. For example, the light source can be positioned to shine light on a back panel of the fireplace. The light source of the backlighting system can be modulated depending on a state of the fireplace. For example, the light source can be turned on or off depending on whether the flame of the fireplace is on or off.Type: GrantFiled: November 19, 2003Date of Patent: January 29, 2008Assignee: HNI Technologies Inc.Inventors: David Charles Lyons, Thomas J.

Publication number: 20070221206Abstract: The artificial embers can generally be used in any gas appliance with a gas fired log set that has a burner and are formed of silicon carbide or alumina. A plurality of the embers are placed loosely on a burner in registry with the flames of the burner in order to produce a simulation of actual glowing embers. The plurality of glowing embers simulates an actual ash bed or coals within the gas fired log set. The glowing artificial embers release a minimal amount of NO2 and CO emissions while creating a more realistic and brighter glow.Type: ApplicationFiled: January 30, 2007Publication date: September 27, 2007Applicant: DESA IP, LLCInventors: John Phillips, George Lewis, Kirk Kirchner, Toby Frink, Albert Talamantes, JoAnn Aiken, Brandon Manco, Jesse Chaney

Patent number: RE40590Abstract: 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.Type: GrantFiled: August 23, 2001Date of Patent: December 2, 2008Assignee: Hearth Technologies Inc.Inventors: Patricia J.
