5.1. Lighting a Burner

1. Place appropriate cookware on the desired burner grate.
2. Push down and turn the corresponding control knob counter-clockwise to the maximum flame setting (large flame symbol).
3. Hold the knob down for a few seconds until the flame ignites. If the flame does not ignite, release the knob and repeat the process.

5.2. Turning Off a Burner

To turn off a burner, turn the control knob clockwise until it clicks into the 'OFF' position (dot symbol).

5.3. Cookware Guidelines

• Use cookware with flat, stable bases.
• Ensure the cookware size is appropriate for the burner to prevent heat loss and ensure even cooking.
• Avoid using oversized cookware that extends significantly beyond the burner grate, as this can affect surrounding surfaces.

6. Maintenance

Regular cleaning and maintenance will ensure the longevity and optimal performance of your cooktop.

6.1. Cleaning the Cooktop Surface

• Allow the cooktop to cool completely before cleaning.
• Wipe the black glass surface with a soft cloth and a mild detergent or glass cleaner.
• For stubborn stains, use a non-abrasive cleaner specifically designed for glass cooktops.
• Avoid abrasive pads, harsh chemicals, or sharp objects that could scratch the surface.

6.2. Cleaning Burner Components

• Remove the burner grates, burner caps, and burner bases when the cooktop is cool.
• Wash these components in warm, soapy water. For heavily soiled parts, a non-abrasive scrub brush may be used.
• Ensure all components are thoroughly dry before reassembling them. Moisture can interfere with ignition.
• Periodically check the burner ports for any blockages and clean them gently with a fine wire or needle if necessary.
