A fireplace and method of manufacturing a fireplace. Embodiments of the fireplace comprise a combustion chamber, a front opening allowing viewing within the combustion chamber, and a back wall opposite the front opening. The back wall can be controllably switched between an opaque state and a transparent state. A combustion region between the front opening and the back wall is adapted to provide a flame. A controller coupled to the back wall enables a user to switch the back wall between the opaque and transparent states. In embodiments the back wall comprises a glass panel and switchable film on the glass panel. The controller is coupled to the switchable film.

A heating appliance includes an outer enclosure including a transparent front panel, a combustion chamber enclosure, and a variable speed blower. The combustion chamber enclosure is positioned within the outer enclosure and defines a combustion chamber wherein radiant heat is generated. The combustion chamber enclosure also includes a transparent front panel. The blower is configured to generate an adjustable airflow between the outer enclosure front panel and the combustion chamber enclosure front panel and to exhaust the airflow to a remote location. The airflow absorbs at least some of the radiant heat and varying a speed of the blower controls an amount of radiant heat transferred from the combustion chamber to a living space in which the heating appliance is exposed.

Fireplace front panel assembly for reducing temperature

An air filtration and sterilization system for removing airborne contaminants from air circulated through an air plenum system of a fireplace. Air filtration systems may include particulate, chemical, and ion filtration systems to filter the air. Air sterilization may include ultraviolet, ozone, germicidal coating, and channeled system of ducts systems to sterilize the air. Systems may be used individually or in combination. In addition, optional components, including a warning sensor for indicating when to replace a filter, an automatic initiation sensor for activating and stopping filtration and sterilization, and an air enhancement system for introducing desirable materials into the air, may be provided.

Air filtration and sterilization system for a fireplace

An apparatus and method for modifying the appearance of a flame to maximize the size of the flame for a given amount of fuel, increase a burn rate efficiency of the flame, or change the shape of the flame. The shape and size of the flame may be modified by applying a secondary source of fluid to the flame. The secondary source of fluid may cause turbulent fluid flow within the combustion chamber enclosure in which the flame is produced to change the appearance of the flame. The secondary source of fluid may be generated by a blower or fan and may include, for example, a source of fresh combustion air, additional flammable gas such as natural gas, or other fluid additives for enhancement of the flame color, shape, and size.

Method and apparatus for modifying the path of a flame

A gas burner includes a monolithic burner panel coupled to a bottom burner member for use as a bottom panel of a combustion chamber enclosure. The burner panel includes at least one aperture for providing a gas/air mixture to a top surface of the burner panel for combustion. The burner panel includes at least one elevated area. The burner panel is a composite material formed from a compression molding process. The burner panel includes elevations that can be shaped into log structures to provide a realistic fire within a fireplace unit, stove, or insert.

Monolithic panel for a gas burner

An apparatus for generating a combustible gas flame above a surface of a liquid. The apparatus may include a manifold including a manifold space that is completely or partially positioned within the liquid and a combustible gas source. Combustible gas from the gas source may be delivered to the manifold space and delivered into the liquid or a space above the liquid. The combustible gas may then be ignited to create a combustible gas flame. The combustible gas may also be mixed with air or liquid prior to delivery to the manifold space. In addition, a pump may be included to pump a supply of liquid out a liquid outlet to create a desired effect. Alternatively, the apparatus may be disposed on a float on the surface of the liquid.

Apparatus for generating a flame out of a liquid

A fireplace including a combustion chamber enclosure with an opening and an inner pane positioned to at least partially cover the opening of the combustion chamber. An outer pane is spaced apart from the inner pane, the outer pane and the inner pane creating a space through which air moves, the air cooling the outer pane. A blower may be provided to move the air through the space. The outer pane may be angled with respect to the inner pane to enhance air movement.

A mixture fitting for use in a combustible gas system, for example, a fireplace. The mixture fitting may include a first portion configured to be coupled to a combustible gas source and a second portion configured to be coupled to a burner assembly. The first and second portions together form a gas passage. The mixture fitting also includes an air orifice extending from an exposed surface of the mixture fitting to the gas passage. The air orifice is configured to allow primary air to travel through the air orifice and into the gas passage to facilitate mixing of air with the combustible gas. Alternatively, the air orifice may be angled, and multiple air orifices may also be provided.

Burner-log element

A low cost prefabricated fireplace is provided with an open-ended fireplace box which requires no outer sheet metal shroud or housing as employed in the prior art sheet metal fireplaces. The novel fireplace box has at least five walls which consist substantially of insulating reinforced ceramic fiber (RCF) material and a binder. A modular burner system is removably mounted on the bottom wall of the fireplace box and a floor panel is mounted on the modular burner system forming an air chamber below the floor panel in the fireplace box. A decorative surround trim is attached to the open end of the fireplace box which serves to support fixed or operable glass doors. A log set which may include a log burner is mounted above the floor panel which supports a decorative log set. Apertures are made in the top sides or of the fireplace box to accommodate an air supply and/or an exhaust stack. The fireplace box serves as a base unit to which other fireplace components are attached, connected or supported so that the need for conventional sheet metal is substantially eliminated. The resulting fireplace can be completed in many different configurations using a common fireplace box which needs no additional surrounding insulation for installation in a room.

A filter includes a center layer of carbon cloth interposed between two layers of filter material whose edges are welded together to provide not only a filter edge substantially free of carbon particles, but also an effective barrier to the migration of carbon particles from the filter's interior to its exterior. A filter pouch, encapsulating the carbon filter, includes a layered structure welded together proximate its edges. The filter pouch is also suitable for use with a desiccant filter.
