Claim Text:
1. A fireplace unit comprising: a pair of spaced apart opposite, upright sidewalls, the sidewalls defining an interior compartment that forms a combustion chamber of the fireplace unit wherein the sidewalls are directly exposed to the combustion chamber, the sidewalls each having a forward end and a rearward end substantially aligned along lines that converge rearwardly, the sidewalls being joined together at the rearward ends so that the joined sidewalls have a substantially triangular transverse cross-sectional configuration, the upper end of each of the sidewall sloping upward from the forward end toward the rearward end; a floor that extends between the sidewalls for closing the lower end of the interior compartment; a sloping cover that is coupled to the upper ends of the sidewalls for closing the upper end of the interior compartment, the cover terminating at a position forward of the rearward ends of the sidewalls, the area beneath the sloping cover defining a smoke chamber; a flue having a flue wall that extends upward from the sloping cover, the flue wall defining a flue interior and having a lower opening for directing smoke and air upward through the flue interior from the interior compartment and smoke chamber; and a first smoke diversion body that extends between the sidewalls, the smoke diversion body having a base end located at or adjacent to the rearward ends of the sidewalls and an opposite projecting end that projects away from the base end and into the smoke chamber so that the smoke diversion body forms a constriction of a smoke flow area of the smoke chamber, the smoke diversion body being oriented so that lines of projection extending between the base end and projecting end are located at an angle of from 1° to 90° from a vertical axis extending through and above the base end of the smoke diversion body, and wherein an opening is formed at the base end of the first smoke diversion body to allow materials to pass therethrough.
