         4 . The fire pit of  claim 2 , wherein the end wall aperture is configured to be closeable with a removeable plate when in the solid fuel burning mode. 
     
     
         5 . The fire pit of  claim 1 , wherein the inner wall is continuous except for the one or more outputs and outer wall is continuous except for the one or more intakes. 
     
     
         6 . The fire pit of  claim 1 , wherein the fuel supply line comprises a hose. 
     
     
         7 . The fire pit of  claim 1 , wherein the fire pit further comprises an accessory mounting apparatus for disposing an accessory relative to the combustion chamber when in the solid fuel burning mode and relative to the burner when in the fluid fuel burning mode. 
     
     
         8 . The fire pit of  claim 2 , wherein the fire pit further comprises a perforated plate configured for supportive engagement with at least one of the wall section or the end wall, the perforated plate configured to support solid fuel at a distance offset from the end wall, the perforated plate further comprising one or more perforations configured to allow waste from spent solid fuel to pass into the offset between the perforated plate and the end wall when in the solid fuel burning mode. 
     
     
         9 . The fire pit of  claim 8 , wherein the perforated plate further comprises a central aperture configured to be in alignment with the end wall aperture, and wherein the fuel supply line is configured to pass through the central aperture when in the fluid fuel burning mode. 
     
     
         10 . The fire pit of  claim 2 , wherein the wall section further comprises an upper end portion defining a closed end of the airflow vent which is on a substantially opposite side of the wall section from the end wall. 
     
     
         11 . The fire pit of  claim 10 , wherein the burner is configured for removable supportive engagement with the upper end portion. 
     
     
         12 . The fire pit of  claim 11 , wherein the burner is supported at a distance offset from the upper end portion in the fluid fuel burning mode. 
     
     
         13 . The fire pit of  claim 1 , wherein the burner is configured for removable supportive engagement with the end wall such that the burner resides within the combustion chamber in the fluid fuel burning mode. 
     
     
         14 . The fire pit of  claim 1 , wherein the burner is configured for removable supportive engagement with the inner wall such that the burner resides within the combustion chamber in the fluid fuel burning mode. 
     
     
         15 . A method of converting a smokeless fire pit between a solid fuel burning mode and a fluid fuel burning mode, the method comprising:
 arranging a burner relative to a combustion chamber defined by a wall section and an end wall, the wall section at least partially defining the combustion chamber, the end wall defining a closed end portion of the combustion chamber, the burner being configured for removable supportive engagement with at least one of the wall section or the end wall and configured to discharge a fluid fuel for combustion when in the fluid fuel burning mode, the wall section comprising:
 an outer wall defining an exterior boundary of an airflow vent within the wall section; 
 an inner wall defining an interior boundary of the airflow vent; 
 one or more intakes configured to intake ambient air to the airflow vent; and 
 one or more outputs in the inner wall configured to output the ambient air from the airflow vent to the combustion chamber; and 
   routing a fuel supply line between a fluid fuel source and the burner to supply the fluid fuel from the fluid fuel source to the burner in the fluid fuel burning mode, wherein the fuel supply line does not pass through the airflow vent when the fire pit is in the fluid fuel burning mode.   
     
     
         16 . The method of  claim 15 , wherein the end wall further comprises an end wall aperture, and wherein the routing of the fuel supply line includes passing the fuel supply through the end wall aperture.
