The knob (Fig. 14) controls the flow of gas through the safety valve.

You can choose to cook at any heat between  and , but never between  and OFF.

Using the burners

1. Choose the control knob for the burner you want to use.

2. Press the knob down gently and turn it anticlockwise to the  position. The ignitors on all the burners will spark.
   Flame failure models only: Hold down the knob for approximately 10 seconds after the burner has lit. Releasing the knob too soon will extinguish the flame.

3. Adjust the flame anywhere between the  and  positions. Do not adjust the flame between  and OFF.

If the burner does not light within 15 seconds, turn the control knob off and wait at least one minute before trying again.

4. After use, always turn the knobs to the off position. For models without the flame failure safety feature, you should also close the cock valve on the gas bottle or the main gas supply line.

Flame failure safety feature (some models only)

Some cooktop models have a flame failure safety device. These models have a flame failure probe as well as the ignitor (see Fig 16).

The flame failure probe cuts off the gas supply to the burner if the flame is blown out.

When lighting the burner on flame failure models, hold down the knob for approximately 10 seconds after the burner has lit. Releasing the knob too soon will extinguish the flame.

If the flames are accidentally extinguished, turn off the burner and do not try to light it again for at least one minute (to allow the gas to disperse).

If a burner does not light

Check that:

• The cooktop is plugged in and the electricity is switched on.
• The gas is turned on.
• The gas bottle is not empty (if you are using bottled gas).
• Flame failure models only:
  You have held down the knob for at least 10 seconds.
• The ignitors are sparking. If the ignitors are not sparking, they may be dirty or wet. Clean them with a toothbrush and methylated spirits, as shown in Fig. 16.

If the flame is irregular

If the flame is yellow or irregular, check that the burner parts, including the burner cap, are:

• Clean and dry.
• Positioned correctly as shown in Figs. 19 and 20.
• See also ‘Troubleshooting’.

Matching cookware to burner

Use flat-bottomed pans, and make sure they match the size of the burner, as shown in the following table. A small pot on a large burner is not efficient.

Wok stand - models fitted with triple-ring wok burner only (Fig. 18b)

The wok stand fits over the triple-ring wok burner trivet.

Using a wok without the stand may cause the wok to tip or the wok burner to operate incorrectly. Do not use the stand for ordinary, flat-bottomed saucepans. The wok stand MUST BE PLACED ONLY over the triple-ring wok burner trivet.
