REGULATION OF BURNERS

TABLE N°4: Burner primary air regulation (indicative)

		Burner

Work surface burner adjustment: follow the instructions below to adjust the work surface burner minimum:

1)Light the burner and set the knob to the MINIMUM position (small flame).

2)Remove the knob of the valve that is press fit on the rod of that valve.

3)The cooker is equipped with safety valves, use a small slotted screwdriver the choke valve located on the valve body and turn the choke screw to the right or left until the burner flame is adjusted to minimum

4)Make sure that the flame does not go out when switching quickly from the MAXIMUM to the MINIMUM position.

Oven burner adjustment: follow the instructions below to adjust the minimum:

1)Light the burner setting the knob to the MAXIMUM position.

2)Close the oven door and operate the oven for at least 10 minutes.

3)Set the knob to the MINIMUM position and then remove it.

4)With a slotted screwdriver turn the choking screw (by-pass screw at the left side of the thermostat bar) and, while observing the flame at the same time through the cooker porthole, evaluate the consistency of the flame so it remains on when switching quickly from the MINIMUM to the MAXIMUM position.

WARNING: The above-mentioned adjustment should be made only for natural gas, while for operation with liquid gas the screw must be locked at the end in a clockwise direction. The broiler burner always operates at maximum and therefore no minimum adjustment is required.
