A cooking assembly has a main burner, a pilot burner mounted in it and having a vent, a gas valve having separate main and pilot gas outlets, and a main-burner controller including a temperature sensor on the main burner, a control unit on the valve capable of varying gas output from the main gas outlet, and a capillary tube connected between the sensor and the control unit. This controller can vary gas flow from the main outlet in accordance with the temperature of the main burner as sensed by the sensor. An electrical igniter on the main burner can be energized by a switch on the valve. A pilot-burner controller connected to the switch includes a thermoelectric sensor in the pilot vent and blocks gas output from the gas outlets when insufficient heat is detected by its sensor and the switch is not closed. When a control knob on the valve is in a closed position no gas is supplied from the outlets to the burners, in a first open position gas is supplied only from the pilot outlet to the pilot burner, in a second open position gas is supplied from both outlets to both burners while closing the switch, and in a third open position gas is also supplied from both outlets to both burners without closing the switch and while controlling the rate of gas flow from the main outlet to the main burner in accordance with the temperature detected by the capillary sensor.
