Before using your cooktop

Before using your new cooktop, please:

• Read this user guide, taking special note of the ‘Safety and warnings’ section.
• Turn the power to the cooker on at the wall.
• Make sure all controls are turned off.

Using the gas 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.
3. Hold down the knob for approximately 10 seconds after the burner has lit. Releasing the knob too soon will extinguish the flame.
4. Adjust the flame anywhere between the  and  positions. Do not adjust the flame between  and 0 (OFF).

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

5. To turn the burner off, turn the knob clockwise to 0 (OFF) until you hear the safety click. After use, always turn the knobs to the 0 (OFF) position.

Flame failure safety feature

• 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).
• 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. 46.

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. See ‘Care and cleaning’.
• See also ‘Cooktop 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.
