Gas burner

A burner unit, comprising:

• a first set of burner assemblies, wherein the first set of burner assemblies includes a first burner assembly having a first flame crown and a second burner assembly having a second flame crown;
• a second set of burner assemblies, wherein the second set of burner assemblies includes a third burner assembly having a third flame crown and a fourth burner assembly having a fourth flame crown;
• first and second valves fluidly coupled to the first set of burner assemblies;
• a first valve control assembly configured to selectively control the first and second valves of the first set of burner assemblies between open and closed positions, wherein the first valve control assembly includes first, second and third control settings;
• third and fourth valves fluidly coupled to the second set of burner assemblies;
• and
• a second valve control assembly configured to selectively control the third and fourth valves of the second set of burner assemblies between open and closed positions.

A burner unit, comprising:

• first and second burner assemblies supplied with a gas mixture via first and second valves, respectively, wherein the first and second valves are selectively operable between open and closed positions, and further wherein the first and second burner assemblies define a first set of burner assemblies, wherein the first and second burner assemblies include first and second flame crowns that are circular flame crowns that are concentric with one another, and further wherein the second flame crown is disposed around and spaced-apart from the first flame crown;
• a first valve control assembly controlling the first and second valves between open and closed positions;
• third and fourth burner assemblies supplied with a gas mixture via third and fourth valves, respectively, wherein the third and fourth valves are selectively operable between open and closed positions independent of the first and second valves, and further wherein the third and fourth burner assemblies define a second set of burner assemblies surrounding the first set of burner assemblies;
• and
• a second valve control assembly controlling the third and fourth valves between open and closed positions, wherein the first and second valve control assemblies are separate assemblies that cooperate to simultaneously provide a gas mixture to the first, second, third and fourth burner assemblies in respective high power settings of the first and second valve control assemblies.
