       12 . The burner assembly of  claim 11 , said restrictor plate and said burner head defining an annular gap therebetween.  
   
   
       13 . The burner assembly of  claim 11 , said restrictor plate defining an aperture therethrough substantially at the center of said restrictor plate.  
   
   
       14 . The burner assembly of  claim 11 , said restrictor plate including a slot for holding a pilot light burner head.  
   
   
       15 . The burner assembly of  claim 1 , said gas-emitting orifices provided in both said upwardly facing and said inwardly facing surfaces of said burner head.  
   
   
       16 . A gas fuel burner head comprising: 
 a substantially annular base;    a substantially annular cover having gas-emitting orifices on only at least one of upwardly and inwardly facing surfaces thereof; and    a restrictor plate limiting airflow through the center of said substantially annular base and top.    
   
   
       17 . The burner head of  claim 16 , said restrictor plate and said cover defining a space between an outer edge of said plate and an inner surface of said cover.  
   
   
       18 . The burner head of  claim 17 , said plate having a hole therethrough.  
   
   
       19 . The burner head of  claim 18 , said plate defining a slot for holding a pilot light.  
   
   
       20 . The burner head of  claim 16 , said cover having inner and outer edges engaging said base and said inner edge being lower than said outer edge.  
   
   
       21 . The burner head of  claim 20 , some of said orifices being lower than said outer edge.  
   
   
       22 . A burner head comprising: 
 a substantially hollow annular body for directing gas flow therethrough, said body having only at least one of upwardly and inwardly facing orifices for emitting gaseous fuel to be burned; and    means controlling the flow of air through said substantially annular body.    
   
   
       23 . The burner head of  claim 22 , said means including a restrictor plate disposed in a central opening defined by said substantially annular body, said restrictor plate being spaced from said substantially annular body to define an airflow gap between said restrictor plate and said substantially annular body.  
   
   
       24 . The burner head of  claim 23 , said restrictor plate further including at least one hole therethrough.  
   
   
       25 . The burner head of  claim 22 , said annular body being a two piece assembly including a burner base and a removable burner top.  
   
   
       26 . A burner head comprising: 
 a substantially annular burner head base having inner and outer base edges and defining an annular open top channel for directing gas flow therethrough;    a substantially annular cover on said base, said cover having inner and outer cover edges engaging said inner and outer base edges, respectively; and    said inner cover edge having an inner lip with an angular surface facing downwardly and laterally for positioning said cover on said base, with said inner lip disposed along the inside of said substantially annular base.
