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 (corresponding to 250°F/120°C) 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.

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.
