Before Using Your New Hob

Before using your new hob, please:

• Read this manual fully taking special note of the 'Safety Warnings' section.
• Plug the hob into the electricity supply and turn it on so that the ignition circuit will work.

This appliance is for cooking purposes only. It must not be used for other purposes, e.g. room heating.

Lighting the Hob

1. Choose the control for the burner you want to use.
2. Press and hold the Burner control in. The spark ignition will operate whilst you hold in the control. While pressing the burner control down, turn it anti-clockwise to the large flame symbol ▶. Continue to hold the control in for approximately 10 seconds after the burner has lit. Releasing the control too soon will extinguish the flame due to the flame failure safety feature.

Manual Ignition (in case of electricity failure)

Off High Low

To ignite one of the burners, press and turn the control counter-clockwise so that the control is at the position. Hold an ignition source (e.g. candle lighter) close to the upper circumference of the burner. Move the ignition source away as soon as you see a stable flame. Continue holding the control in for approximately 10 seconds after the burner has lit. Releasing the control too soon will extinguish the flame due to the flame failure safety feature.

1. Adjust the flame anywhere between the and positions. Do not adjust the flame between the and Off position.
2. After ignition, check the flames visually. If you see yellow tipped, lifted or unstable flames; turn the control off. Allow the burners to cool before touching, then check the assembly of the burner rings and caps. Also, make sure that no liquid has entered into the burner cups. If the burner flames go out accidentally, turn the burners off, and do not try to light them again for at least 90 seconds (to allow the gas to disperse).
3. When turning the hob off, turn the control in a clockwise direction to the off mark, ' ●'.

• If the burner does not light within 15 seconds, turn the control off and wait for at least 90 seconds before trying again.
  • To switch the burner off, turn the control clockwise to the off position.
  • After use, always turn the controls to the off position.

• This appliance is for cooking purposes only. It must not be used for other purposes, for example room heating.
• The use of a gas cooking appliance results in the production of heat, moisture and products of combustion in the room in which it is installed. Ensure that the kitchen is well ventilated especially when the appliance is in use: keep natural ventilation holes open or install a mechanical ventilation device (mechanical extractor hood). Prolonged intensive use of the appliance may call for additional ventilation, e.g. opening of a window, or more effective ventilation, e.g. increasing the level of mechanical ventilation where present.

Flame Failure Safety Feature

The flame supervision device (FSD) probe cuts off the gas supply to the burner within one minute if the flame is extinguished. Gas will flow out of the burner until the FSD cools down and activates, so you may notice the smell of gas, this is normal.

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).

When lighting the burner, hold down the control for approximately 5 – 10 seconds after the burner has lit. Releasing the control too soon will extinguish the flame.

If the Burner Does Not Light

If the burner does not light, check that:

• The hob is connected to the electrical supply and the supply is switched on.
• The gas is turned on.
• You have held down the control for at least 5 – 10 seconds after the flame has been lit.
- The ignitors are sparking. If the ignitors are not sparking, they may be dirty or wet. Clean them gently with a small nylon brush such as a toothbrush as shown below. Ensure the electrical supply has been disconnected before cleaning.

To avoid damage to the ignition circuit NEVER light the hob when the burners are not in place.

Ignitor Flame failure probe

If the Flame is Irregular

If the flame is yellow or irregular, check that the burner parts, including the burner cap (allow to cool before touching), are:

• Clean and dry.
• Positioned correctly. See 'Replacing the Burners'.
  • Also see 'Hints and Tips'.

Cookware Guidelines

To get the best out of your hob, follow these simple suggestions:

- Use saucepans with thick flat bottoms. Food in a saucepan with an uneven bottom will take longer to cook.

Diagram showing three cooking pots with checkmark and cross symbols below each, likely indicating cooking or testing status.

• Do not use large saucepans or frying pans that overlap the edges of your hob as this can deflect heat onto your worktop and damage the surface, and may also cause a hazard.
  • Always make sure saucepans are stable. Using very heavy saucepans may bend the trivet/pan support or deflect the flame.
  • Always lift the cookware when removing from the hob, do not drag.
• When you need to boil, simmer or fry food, first set the temperature to the High position. Once the food is boiling, reduce the temperature to maintain a steady heat to cook your food thoroughly. Doing this will reduce the cooking time and save energy.
  • Pan sizes should be as per the table shown below.

Burners Minimum Diameter Maximum Diameter
Large (130mm) 22 cm 30 cm
Standard (70mm) 14 cm 20 cm
Small (50 mm) 12 cm 18 cm

Two line drawings of a cooking pot with steam rising from its side, showing heating and cooling cycles (no text or symbols)

Do not use cooking vessels on the hob that overlap its edges.

• Using a lid will reduce cooking times and save energy.
- When liquid comes to a boil, reduce the temperature setting to maintain the desired level of boiling.
- Choose cookware of the proper size, material and construction.
- Minimise the amount of liquid or fat to reduce cooking times.
- Select the proper temperature setting for the cooking task.
