Gas Connection

Assembly of gas supply and leakage check

Connect the appliance in accordance with applicable local and international standards and regulations. First, check what type of gas is installed on the cooker. This information is available on a sticker on the back of the cooker. You can find the information related to appropriate gas types and appropriate gas injectors in the technical data table. Check that the feeding gas pressure matches the values on the technical data table, to be able to get the most efficient use and to ensure the minimum gas consumption. If the pressure of used gas is different than the values stated or is not stable in your area, it may be necessary to assemble an available pressure regulator on the gas inlet. You should contact an authorised service centre to make these adjustments.

Points that must be checked during flexible hose assembly:

• If the gas connection is made by a flexible hose fixed onto the gas inlet of the hob, it must be fixed on by a pipe collar.
• Connect your appliance with a short and durable hose that is as close as possible to the gas source.
• The permitted maximum length of the hose is 1.5 m.
• The device should be connected in line with the relevant local gas standards.
• The hose must be kept clear of areas that may heat up to temperatures of more than 90°C.
• The hose must not be cracked, torn, bent or folded.
• Keep the hose clear of sharp corners and objects that could move.
• Before you assemble the connection, you must make sure the hose is not damaged. Use bubbly water or leakage fluids to perform the check. Do not use a naked flame to check for gas leakage.
• All metal items that are used during gas connection must be free from rust. Check the expiry date of any components used for connection.

Points that must be checked during fixed gas connection assembly:

The method used to assemble a fixed gas connection (gas connection made by threads, e.g. a nut) varies according to the country you are in. The most common parts for your country will be supplied with your appliance. Any other parts required can be supplied as spare parts.
During connection, always keep the nut on the gas manifold fixed while rotating the counter-part. Use appropriately-sized spanners for a safe connection. For surfaces between different components always use the seals provided in the gas conversion kit.
The seals used during connection should also be approved to be used in gas connections. Do not use plumbing seals for gas connections.
Remember that this appliance is ready to be connected to the gas supply in the country for which it has been produced.
The main country of destination is marked on the rear cover of the appliance. If you need to use it in another country, any of the connections in the figure below may be required. In such a case, contact local authorities to learn the correct gas connection.

The Cooker must be installed and maintained by a suitably qualified gas registered technician in accordance with current safety legislation.

WARNING : Do not use a naked flame to check for gas leaks.

Gas Conversion (If available)

Your appliance is designed to be operated with LPG/NG gas. The gas burners can be adapted to different types of gas, by replacing the corresponding injectors and adjusting the minimum flame length suitable to the gas in use. For this purpose, the following steps should be performed.

Changing injectors Hob burners

• Cut off the main gas supply and unplug the appliance from the mains electrical supply.
• Remove the burner caps and the adapters.
• Use a 7 mm spanner to unscrew the injectors.
• Replace the injector with the ones from the gas conversion kit, with the correct diameters for the type of gas that is going to be used, according to the gas injector table.

Adjusting the reduced flame position

First of all, make sure that the appliance is unplugged from the the mains electrical supply and that the gas feed is open. The minimum flame position is adjusted with a flat screw located on the valve. For valves with a flame failure safety device, the screw is located on the side of the valve spindle as shown in the figures. For valves without a flame failure safety device, the screw is located inside the valve spindle as shown in the figure. To make adjusting the flame position easier, we recommend that you remove the control panel (and the micro switch if your model has one) during the alteration.
To determine the minimum position, ignite the burners and leave them on in the minimum position. With the help of a small screwdriver, fasten or loosen the bypass screw by around 90 degrees. When the flame has a length of at least 4mm, the gas is well distributed. Make sure that the flame does not die out when passing from the maximum position to the minimum position. Create an artificial wind with your hand towards the flame to see if the flames are stable.
The bypass screw must be loosened for conversion from LPG to NG. For conversion from NG to LPG, the bypass screw must be tightened. Make sure that the appliance is unplugged from the mains electrical supply and that the gas feed is open.

Changing the gas inlet

For some countries, the gas inlet type can be different for NG/LPG gases. In this case, remove the current connection components and nuts (if any) and connect the new gas supply accordingly. In all conditions, all components used in gas connections should be approved by local and/or international authorities. In all gas connections, refer to the “Assembly of gas supply and leakage check” clause explained above.

Electrical Connection and Safety (If available)

WARNING : The electrical connection of this appliance should be carried out by an authorised service person or qualified electrician, according to the instructions in this guide and in compliance with the current local regulations.

WARNING: THE APPLIANCE MUST BE EARTHED.

• Before connecting the appliance to the power supply, the voltage rating of the appliance (stamped on the appliance identification plate) must be checked for correspondence to the available mains supply voltage, and the mains electric wiring should be capable of handling the appliance’s power rating (also indicated on the identification plate).
• During installation, please ensure that isolated cables are used. An incorrect connection could damage your appliance. If the mains cable is damaged and needs to be replaced this should be done by a qualified personnel.
• Do not use adaptors, multiple sockets and/or extension leads.
• The supply cord should be kept away from hot parts of the appliance and must not be bent or compressed. Otherwise the cord may be damaged, causing a short circuit.
• If the appliance is not connected to the mains with a plug, a all-pole disconnector switch (with at least 3 mm contact spacing) must be used in order to meet the safety regulations.
• The fused switch must be easily accessible once the appliance has been installed.
• Ensure all connections are adequately tightened.
• Fix the supply cable in the cable clamp and then close the cover.
• The terminal box connection is placed on the terminal box.

USE OF PRODUCT

Use of gas burners

Ignition of the burners

The position symbol above each control knob indicates the burner that the knob controls.

Manual Ignition of the Gas Burners

If your appliance is not equipped with an ignition aid, or in case there is a failure in the electric network, follow the procedures listed below.

For Hob Burners: Push in the knob of the burner you wish to ignite and keep it pressed while turning it anti-clockwise until the knob is in the ‘maximum’ position. Continue pressing the knob and hold a lit match, taper or other manual aid to the upper circumference of the burner. Move the ignition source away from the burner as soon as you see a stable flame.

Electrical ignition by control knob

Push in the knob of the burner you wish to ignite and keep it pressed while turning it anticlockwise until the knob is in the 90 degrees position. The microswitch under the knob will create sparks through the spark plug for as long as the control knob is pressed. Press the knob until you see a stable flame on the burner.

Flame safety device Hob burners

Hobs equipped with a flame failure device provide security in case of an accidentally extinguished flame. If such a case occurs, the device will block the burners gas lines and will avoid any accumulation of unburned gas. Wait 90 seconds before re-igniting an extinguished gas burner. Hob Controls

Hob burner

The knob has 3 positions: off (0), maximum (big flame symbol) and minimum (small flame symbol). Ignite the burner with the knob in the ‘maximum’ position; you can then adjust the flame length between the ‘maximum’ and ‘minimum’ positions. Do not operate the burners when the knob is between the ‘maximum’ and ‘off’ positions.

After ignition, visually check the flames. If you see a yellow tip, lifted or unstable flame, switch the gas flow off, then check the assembly of burner caps and crowns once they have cooled. Make sure there is no liquid in the burner caps. If the burner flames go out accidentally, switch the burners off, ventilate the kitchen with fresh air and wait at least 90 seconds before attempting re-ignition.

To switch the hob burners off, turn the hob burner knob clockwise to the ‘0’ position or so that the marker on the hob burner knob points upwards.

Your hob has burners of different diameters. You will find that the most economical way of using gas is to choose the correct size gas burner for your cooking pan size and to bring the flame to the ‘minimum’ position once boiling point is reached. We recommend that you always cover your cooking pan to avoid heat loss.

To obtain maximum performance from the main burners, we suggest you use pots with the following flat bottom diameters. Using pots smaller than the minimum dimensions shown below will cause energy loss.

Make sure that the tips of the flames do not spread out from the outer circumference of the pan, as this may harm plastic accessories, such as handles.

Switch the main gas control valve off when the burners are not in use for prolonged periods of time.

  WARNING:

• Only use flat-bottomed pans with thick bases.
• Make sure the bottom of the pan is dry before placing it on the burner.
• The temperature of accessible parts may become high while the appliance is operating. It is imperative that children and animals are kept well away from the burners during and after cooking.
• After use, the hob remains very hot for a prolonged period of time. Do not touch it and do not place any object on top of it.
• Never place knives, forks, spoons and lids on the hob as they will get hot and could cause serious burns.
• Do not allow pan handles or any other cooking utensils to project over the edge of the cooker top.
  

Accessories

The Coffee Adaptor

Place the coffee adaptor on the auxiliary burner grid to prevent the cookware from tipping over when the small burner is in use.
