         4 . The gas cooking appliance of  claim 2 , wherein said single piece includes the at least one burner body. 
     
     
         5 . The gas cooking appliance of  claim 2 , wherein said single piece includes the gas rail. 
     
     
         6 . The gas cooking appliance of  claim 2 , wherein said single piece includes the at least one gas connection pipe. 
     
     
         7 . The gas cooking appliance of  claim 2 , wherein said single piece includes the connection member. 
     
     
         8 . The gas cooking appliance of  claim 2 , wherein it comprises a plurality of burner bodies ( 5 ) and a plurality of gas connection pipes ( 10 ), each connection pipe being designed to feed gas from the gas rail to a corresponding burner body, and wherein said single piece includes all the burner bodies and all the connection pipes. 
     
     
         9 . The gas cooking appliance of  claim 1 , wherein said single piece includes also a plurality of joints ( 11 ) connecting each other different parts of said single piece. 
     
     
         10 . The gas cooking appliance of  claim 1 , wherein the support frame comprises a horizontal plate ( 2 ) having at least one seat for hosting said at least one burner and wherein the plate is made of thermosetting or thermoplastic material. 
     
     
         11 . The gas cooking appliance of  claim 1 , wherein it comprises a plurality of burners, each burner including a burner body ( 5 ), and wherein all the burner bodies are made of thermosetting or thermoplastic material. 
     
     
         12 . The gas cooking appliance of  claim 1 , wherein the gas feeding circuit comprises a plurality of gas connection pipes ( 10 ;  110 ) to feed gas to said burners, and wherein all of the gas connection pipes ( 10 ;  110 ) are made of thermosetting or thermoplastic material. 
     
     
         13 . The gas cooking appliance of  claim 1 , wherein the support frame comprises at least one crossbar ( 144 ) holding said at least one burner and wherein the crossbar is made of thermosetting or thermoplastic material. 
     
     
         14 . A process for producing a gas cooking appliance ( 1 ;  101 ) comprising at least the following components:
