1. A cooktop appliance comprising:
a gas burner;
a manifold having a gas input;
a primary line extending between the manifold and the gas burner, wherein a gas flow rate in the primary line is controllable by a user selectable interface; and
a secondary line extending between the manifold and the gas burner, wherein a gas flow rate in the secondary line is controllable by a flow control valve, and
wherein the user selectable interface comprises a knob in mechanical communication with a manual valve disposed along the primary line to selectively control the gas flow rate in the primary line between a minimum and a maximum flow rate based on a position of the knob.
