A gas fireplace is provided having a plenum formed around at least a portion of the fireplace firebox. Room air enters the plenum and is heated by the firebox prior to venting back into the room. Two openings are provided from the outside of the fireplace housing to the plenum. The first opening allows heated air to exit the plenum, while the second opening allows cool outside air to enter the plenum. a mechanism is provided to control the amount of heated air exiting the first opening and the amount of cool air entering the second opening. By controlling the inflow and outflow through the first and second openings, respectively, the amount of the fireplace by-products generated into the room where the fireplace is located such as carbon-monoxide, nitrogen dioxide, heat and moisture are reduced.

Fireplace

An artificial log is provided for use in a gas fireplace combustion chamber. A portion of the log outer surface has a charred appearance. When the fireplace is turned on and the log is heated, the log rotates to bring the charred surface in view from an open end of the fireplace combustion chamber so as to provide the appearance of a real wood log being burned. When the fireplace is turned off, the log rotates back to a position hiding the charred surface from view so as to have the appearance of a brand new log.

Gas fireplace with rotating log assembly

A burner assembly for use in a gas burning fireplace for producing flame patterns simulating flame patterns produced by real burning wood, and a method for producing such flame patterns. A preferably cylindrical bluff body is placed into the gas flow path from a supply line dividing the flow into a first and a second flow and generating Karman vortices within each flow. The vortices between the two flows are staggered. Each flow enters into a burner and exits through the burner ports where it is ignited to produce a flame pattern. The vortices create a rotating turbulence within each flow such that each flow has relatively steady flow portions alternating with turbulent rotating portions. This variance in the flow results in flames that have varying intensity, as well as color, and produces flame patterns simulating those produced by real burning wood.

A vent free gas fireplace comprises a housing and a firebox within the housing spaced-apart from the housing walls to provide top, bottom, rear and side plenums. The side plenums are divided into upper and lower side plenums. Room air enters the lower side plenum and passes into the rear plenum, the combustion chamber and the upper side plenum. Exhaust gases pass from the combustion chamber through a catalytic converter and into the top plenum. The hot exhaust gases are combined with room air from the rear plenum and pass into the upper side plenums, combining with additional room air, and then out into the room.

A closed-combustion gas fireplace having a glass panel and a means for reducing the temperature of the upper end of the glass panel is disclosed. The temperature reducing means comprises a downwardly depending baffle spaced apart from the upper end of the glass panel to form a channel within the combustion chamber adjacent the upper end of the glass panel. The channel reduces movement of hot gases adjacent the upper end of the glass panel thereby reducing the glass temperatures at that location.

A sealed-combustion chamber fireplace includes a combustion air to fuel adjustment device comprising an primary air-fuel mixing body having a fuel source inlet at one end and at least one combustion air inlet port disposed through a wall portion of the body. The air-fuel mixture body may be configured in the form of an air-fuel venturi, burner tube and the like to effect mixing together of the air and fuel to form a combustible air-fuel mixture. An air inlet port cover is movably disposed adjacent the air-fuel mixing body and forms an adjustable air combustion aperture by placement of the cover adjacent the air inlet port. Movement of the cover about the body effects opening or closing of the aperture, thereby effecting adjustment of the primary air to fuel ratio of the air-fuel mixture combusted in the combustion chamber. A cover arm is attached to the cover and an actuator arm is movably attached to the cover arm to facilitate adjustment of the aperture, thereby, permitting adjustment of the flame appearance during operation of the fireplace from a position outside of the fireplace.
