         7 . The burner assembly of  claim 1 , wherein the fuel inlet of the elongated burner is a single passage. 
     
     
         8 . The burner assembly of  claim 1 , wherein the fuel inlet of the elongated burner and the fuel inlet of the round burner each comprise a respective Venturi mixing tube. 
     
     
         9 . The burner assembly of  claim 1 , wherein the control valve is selectively adjustable in order permit fuel flow to the round burner, the elongated burner, or both the round burner and the elongated burner. 
     
     
         10 . The burner assembly of  claim 1 , wherein the control valve has only two outlets. 
     
     
         11 . A burner assembly, comprising:
 a round burner having a fuel inlet; and   an elongated burner having a fuel inlet with a single Venturi mixing tube, the elongated burner also having a middle portion, the round burner positioned at the middle portion of the elongated burner, the elongated burner configured such that all fuel flowing into the elongated burner passes through the single Venturi mixing tube.   
     
     
         12 . The burner assembly of  claim 11 , further comprising:
 a control valve having an inlet and a pair of outlets;   a first supply conduit extending from a first one of the pair of outlets of the control valve in order to direct fuel to the fuel inlet of the round burner; and   a second supply conduit extending from a second one of the pair of outlets of the control valve in order to direct fuel to the fuel inlet of the elongated burner.   
     
     
         13 . The burner assembly of  claim 12 , wherein the control valve selectively adjustable in order permit fuel flow to the round burner, the elongated burner, or both the round burner and the elongated burner. 
     
     
         14 . The burner assembly of  claim 11 , wherein the elongated burner comprises a burner base and a bottom plate, the burner base extending between a first end portion and a second end portion, the burner base defining a first plurality of flame ports at the first end portion of the burner base and a second plurality of flame ports at the second end portion of the burner base, the bottom plate mounted to the burner plate and defining the fuel inlet of the elongated burner, the burner base and the bottom plate defining a fuel chamber therebetween, fuel from the fuel inlet of the elongated burner flowing through the fuel chamber to the first and second pluralities of flame ports. 
     
     
         15 . The burner assembly of  claim 14 , wherein the elongated burner further comprises a pair of cover plates, a first one of the pair of cover plates positioned at the first end portion of the burner base over the first plurality of flame ports, a second one of the pair of cover plates positioned at the second end portion of the burner base over the second plurality of flame ports. 
     
     
         16 . The burner assembly of  claim 14 , wherein the single Venturi mixing tube of the elongated burner extends from the bottom plate away from the burner base 
     
     
         17 . The burner assembly of  claim 14 , the bottom plate is screwed, staked or riveted to the burner plate.
