Claims25
A deep fryer, comprising:
- a cooking vessel for holding a cooking medium;
- and
- a natural draft combustion system comprising:
- at least one supply conduit for receiving and distributing a combustion gas;
- at least one burner in fluid communication with the at least one supply conduit;
- a combustion chamber in fluid communication with the at least one burner, the combustion chamber being exterior to the cooking vessel, being connected to an exterior surface of the cooking vessel, and being in heat transfer communication with the exterior surface of the cooking vessel;
- a baffle system disposed within the combustion chamber;
- and
- at least one deflector disposed at least partially within the combustion chamber to adjustably increase or decrease the volume of the combustion chamber when the deflector is opened or closed.

A method of manufacturing a deep fryer, comprising:
- providing a cooking vessel for holding a cooking medium;
- coupling a natural draft combustion system to the cooking vessel, the natural draft combustion system being formed by:
- providing at least one supply conduit for receiving and distributing a combustion gas;
- placing at least one burner in fluid communication with the at least one supply conduit;
- connecting at least one combustion chamber along an exterior surface of the cooking vessel, such that the at least one combustion chamber is in fluid communication with the at least one burner and being in heat transfer communication with the exterior surface of the cooking vessel;
- installing a baffle system within the combustion chamber;
- and
- at least one deflector disposed at least partially within the combustion chamber to adjustably increase or decrease the volume of the combustion chamber when the deflector is opened or closed.
