Flame Failure Safety Feature
The flame supervision device (FSD) 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 control for approximately 5 to 10 seconds after
the burner has lit. Releasing the control 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).
Before Using Your Cooker
Before using your new cooker, please:
• Read this instruction/installation manual, taking special note of the "Safety Warnings" section.
• Make sure all the controls are turned off.
• Turn the mains power on.
Lighting the Hob Burners
1. Choose the control for the burner you want to use.
2. Press the ignition button and at the same time press the control of the burner you want to operate and turn
the control counter-clockwise direction so that the control is at the maximum position. Continue pressing
the ignition button until the burner has lit, and continue holding the control in for approximately 5 to 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)
To ignite one of the burners, press and turn the control counter-clockwise so that the control is at its
maximum 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 5 to 10 seconds after the burner has lit. Releasing the control too soon will extinguish the
flame due to the flame failure safety feature.
3. After ignition, check the flames visually. If you see yellow tipped, lifted or unstable flames; turn the control
off, and 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 1 minute (to allow the gas to disperse).
4. When turning the hob off, turn the control in a clockwise direction so that the control shows 0 position in
line with the marking on the control panel.
• If the burner does not light within 15 seconds, turn the control off and wait for at least one minute
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.

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 ‘Replacing the Burners’.
• Also see 'Hints and Tips'.
Using the Hob
The control has 3 positions: OFF, maximum ( ) and minimum ( ). After you have ignited the burner at the
maximum position ( ), you should adjust the flame length for cooking between the maximum ( ) and
minimum ( ) flame positions. You must not cook with the control between the maximum ( ) and OFF
positions.
Flame failure probe
Ignitor
If the Burner Does Not Light
If the burner does not light, check that:
• The cooker is switched on at the mains supply to enable the ignition circuit to work.
• The gas is turned on.
• You have held in the control for at least 5 to 10 seconds.
• 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.
Never operate the ignition without the burner parts in position. You may damage the electric
ignition.

• Do not let large saucepans or frying pans overlap the edges of your hob as this can deflect heat onto your
worktop and damage the surface.
• 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 flow of heat to cook your food
thoroughly. Doing this will reduce the cooking time.
• Your cooker has burners of different diameters. The most economical way of using gas is too choose the
correct size gas burners for your cooking pan size and to bring the flame to minimum position once the boiling
point has been reached. It is recommended to always cover your cooking pan.
• In order to obtain maximum performance from the main burners, use saucepans with the following flat
bottom diameters. Using smaller saucepans than the minimum dimensions stated below will cause energy
loss.
• Saucepan sizes should be as per the table shown below.
Burners Diameter Minimum Diameter Maximum Diameter
Small (Simmer) 12 cm 18 cm
Standard 14 cm 22 cm
Large (Fast) 22 cm 26 cm
General 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.
Do not use cooking vessels on the hob that overlap the edges of the hob.
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, for example opening of
a window, or more effective ventilation, for example increasing the level of mechanical ventilation
where present.

Lighting the Oven Burner
1. Press the ignition button and at the same time press the oven control and turn counter-clockwise so that
the control is at the maximum position. Continue pressing the ignition button until the burner has lit,
continue holding the control in for approximately 5 to 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)
To ignite the oven burner, press and turn the control counter-clockwise so that the control is at its maximum
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 5 to 10 seconds after the burner has lit. Releasing the control too soon will extinguish the
flame due to the flame failure safety feature.
2. After ignition, check the flames visually. If you see yellow tipped, lifted or unstable flames; turn the control
off. If the burner flames go out accidentally, turn the burner off, open the door and do not try to light it
again for at least 1 minute (to allow the gas to disperse).
3. When turning the oven off, turn the control in a clockwise direction so that the control shows
0 (OFF) position in line with the marking on the control panel.
First Time Use of the Oven
Ensure that nothing has been left in the oven. Remove any insert cards or plastic bags. Before connecting the
power, use a damp cloth to carefully wipe the inner cavity wall and housing. Clean all the detachable parts in hot,
soapy water before using.
Heat the oven on maximum for 45 minutes. (Please refer to the "Lighting the Oven Burner" section) There may
be a little smoke and odour upon initial start up (for about 15 mins). This is normal. It is due to the protective
substance which protects the cooker from the effects of corrosion during shipping from the factory.
Oven Control
This controls the oven burner.
Turn the control anti-clockwise and set to the relevant
setting needed.
• If the burner does not light within 15 seconds, turn the control off and wait for at least one minute
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.

Replacing the Anti-tilting Oven Shelf
• Insert the shelf at an angle with the vertical section to the rear to clear
the stops at either side of the guide slot. Once past this stop the shelf
can be placed level again.
• To remove completely, angle the shelf upward so the shelf stop is
cleared from the guide stop.
Flame Failure Safety Feature
The flame supervision device (FSD) probe cuts off the gas supply to the oven burner if the flame is blown out.
When lighting the burner on flame failure models, hold in the control for approximately 10 seconds after the
burner has lit. Releasing the control 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).
Before Using the Oven
1. On the wall of the inner cavity there are 6
different shelf guide slots. You can place the
shelf at different heights to achieve the best
cooking performance depending on the heat of
the oven and the size of the food.
2. Always monitor the food during operation to
ensure that you are not overcooking it.

Guide 1
Using the Oven
After you ignite the oven burner as explained before, you can adjust the temperature inside the oven as you
require, using the numbers on the control: Larger numbers mean higher temperatures, while smaller numbers
mean lower temperatures. Refer to the temperature table on the next page for the approximate temperature
references of those numbers. Do not operate the appliance between the OFF position and first temperature
marker in the counter-clockwise direction. Always use the oven between the maximum and the minimum
numbers. When turning the oven off, turn the control in the clockwise direction so that the control shows the 0
position.
Accessible parts may become hot during use. Young children should be kept away.

Preheating
When you need to preheat the oven, we recommend you do so for 10 minutes. For recipes needing high
temperatures, e.g. bread, pastries, scones, soufflés etc., best results are achieved if the oven is preheated first. For
best results when cooking frozen or cooked chilled ready meals always preheat the oven first.
Cooking
• Ensure that food is placed centrally on the shelf and that there is sufficient room around the baking tray/dish
to allow for maximum heat circulation.
• Stand dishes on a suitably sized baking tray on the shelf to prevent spillage onto the oven base and to help
reduce cleaning.
• The material and finish of the baking tray and dishes used affect browning of the bottom of the food. Enamelware, dark, heavy or non-stick utensils increase browning of the bottom of the food. Shiny aluminium or
polished steel trays reflect the heat away and give less browning of the bottom of the food.
• When cooking more than one dish in the oven, place dishes centrally on different shelves rather than cluster
several dishes on one shelf, this will allow the heat to circulate freely for the best cooking results.
• If you are cooking more than one tray of similar items, for example cakes or biscuits, swap the trays during
cooking or you can remove the top tray when the food is cooked and move the lower tray to the higher shelf
to finish cooking.
• Do not place baking trays directly on the oven base as it interferes with the oven air circulation and can lead to
burning of the food. Use the lower shelf position.
The thermostat settings detailed below are a guide only and refer to the temperature in the centre of the oven.
Main Oven S 1 2 3 4 5 6 7 8 9
Temperature in °C 100 130 140 160 180 190 200 220 240 255
• If accurate temperatures are required then this should be checked using an oven thermometer available at
most cookware shops.
• During cooking, do not open the door unnecessarily as you will lose heat and your cooking results may
change.
• Using cake tins when cooking cakes will give better results.

Cooking
• The grill burner can be adjusted between the
maximum and the minimum positions as indicated
on the control. When turning the grill burner off,
turn the control towards the "0" position. The
control will need to be pushed in to turn off from
the maximum position.
• Place an oven shelf in either guide slot 1 or 2
(cooking will be slower on slot 1). Ensure there is
a minimum of 30 mm between the food and the
burner, if not use the lower slot.
• Preheat the grill on a full setting for a few minutes
before sealing steaks or toasting. The food should
be turned over during cooking as required.
• Food should be thoroughly dried before grilling
to minimise splashing. Brush lean meats and fish
lightly with a little oil or melted butter to keep
them moist during cooking.
• Foods should be placed in the centre of the grill
rack to allow maximum circulation of air.
• Never cover the grill pan or grill rack with foil as
this can lead to grill fires.
Using the handle, insert the grill tray and rack onto the oven shelf positioned in guide slot 1 or 2 (The cooking
will be slower using guide slot 1). The food to be cooked must be placed on the grill rack. Ensure there is at least
30 mm between the food and the grill burner. The handle must be removed once the grill rack tray is in position.
Check the food regularly to ensure you do not overcook it.
The grill pan has a detachable handle. Ensure when using the grill pan handle that it is centralised and secure as
shown below.
Using the Grill
The grill burner can be operated with the oven door in two positions: completely open or partially open (30° park
position). Do not use the grill with the door closed.
Guide 2
Guide 1
CAUTION: Accessible parts may be hot when the grill is in use. Young children should be kept away.
Ensure that the grill is turned off before closing the door.
• Bread may catch fire if the toasting time is too long. Close supervision is necessary during toasting.
• Do not leave the handle in position when grilling. If the handle is left in position when grilling, it
will get very hot.
