Preformed fireplace capable of venting vertically or horizontally

Abstract

A gas fireplace is provided including a first housing having a first upper wall, and a second housing within the first housing having a second upper wall spaced apart from the first upper wall and defining a space there between. A combustion chamber is defined within said second housing. The fireplace further includes an elbow flue for the exhaust of gases generated in the fireplace. The elbow flue is coupled to the second upper wall and extends within the space. The elbow flue is rotatable relative to the upper walls about a vertical axis.

         4 . The fireplace as recited in  claim 3  wherein the first elbow flue second section is coupled to the second elbow flue first section and wherein the second and third longitudinal axis are aligned along a line. 
     
     
         5 . The fireplace as recited in  claim 3  wherein the second elbow flue extends above the first upper wall and wherein the first elbow flue extends below the first upper wall. 
     
     
         6 . The fireplace as recited in  claim 3  wherein the second elbow flue is rotatable to position said fourth longitudinal axis in a generally vertical position and is rotatable to position said fourth longitudinal axis in a generally horizontal position. 
     
     
         7 . The fireplace as recited in  claim 6  wherein the first angle is 45°, and wherein the second angle is 45°. 
     
     
         8 . The fireplace as recited in  claim 6  wherein the sum of the first and second angles is 90°. 
     
     
         9 . The fireplace as recited in  claim 2  further comprising another flue extending vertically from the second upper wall, wherein the first elbow flue is coupled to the said another flue and whereby said another flue is located between said first elbow flue and said second upper wall. 
     
     
         10 . The fireplace as recited in  claim 2  wherein said elbow flue allows for the intake of air into the combustion chamber and for the exhaust of said gases. 
     
     
         11 . The fireplace as recited in  claim 1  further comprising a second elbow flue coupled to the first elbow flue, said second elbow flue comprising a first section and a second section, wherein said first section of said second elbow flue comprises a third longitudinal axis, wherein said second section of said second elbow flue comprises a fourth longitudinal axis extending a second angle relative to the third longitudinal axis, wherein said first section of said second flue is rotatable about said third longitudinal axis. 
     
     
         12 . The fireplace as recited in  claim 11  wherein the first elbow flue second section is coupled to the second elbow flue first section and wherein the second and third longitudinal axis are aligned along a line. 
     
     
         13 . The fireplace as recited in  claim 11  wherein the second elbow flue extends above the first upper wall and wherein the first elbow flue extends below the first upper wall. 
     
     
         14 . The fireplace as recited in  claim 11  wherein the second elbow flue is rotatable to position said fourth longitudinal axis in a generally vertical position and is rotatable to position said fourth longitudinal axis in a generally horizontal position. 
     
     
         15 . The fireplace as recited in  claim 14  wherein the first angle is 45°, and wherein the second angle is 45°. 
     
     
         16 . The fireplace as recited in  claim 14  wherein the sum of the first and second angles is 90°. 
     
     
         17 . The fireplace as recited in  claim 11  further comprising another flue extending vertically from the second upper wall, wherein the first elbow flue is coupled to the said another flue and whereby said another flue is located between said first elbow flue and said second upper wall. 
     
     
         18 . The fireplace as recited in  claim 11  wherein said elbow flue allows for the intake of air into the combustion chamber and for the exhaust of said gases. 
     
     
         19 . A gas fireplace comprising:
 a first housing having a first upper wall;   a second housing within the first housing having a second upper wall spaced apart from the first upper wall and defining a space between the first and second upper walls, wherein a combustion chamber is defined within said second housing; and   an elbow flue for the exhaust of gases generated in the fireplace comprising a first end coupled to the second upper wall and a second end, wherein a majority of said elbow flue is within the space, and wherein said elbow flue is rotatable for orienting the second end at different orientations.
