Compliance with standards

This cooktop must be installed by an authorised person in accordance with the requirements of local gas and electrical authorities, as well as the latest published versions of the following standards:

AS/NZS 5601 Gas installation and pipe sizing
- SAA Wiring Rules.

Positioning

! Keep packaging material out of the reach of children. It can become a choking or suffocation hazard (see Precautions and tips).

The appliance must be installed by a qualified and authorised professional according to the instructions provided. Incorrect installation may cause harm to people and animals or may damage property.

Kitchen Ventilation

Where the total input of all appliances exceeds 3MJ / h for each cubic metre of the room or enclosure volume, the space shall be ventilated by one of the methods detailed below. For the purpose of assessing the adequacy of ventilation, the space that cannot be isolated by doors is the 'volume of a room'.

Natural ventilation direct from outside

Two permanent openings shall be provided directly to outside. The openings shall be located to ensure the distance between the top of the upper opening and the ceiling of the room or enclosure, and the distance between the bottom of the lower opening and the floor of the room or enclosure does not exceed 5% of the height of the room or enclosure. The minimum free ventilation area provided by each opening shall be calculated using the following formula:

A=3×T

where

A = the minimum free ventilation area (cm ^2 )

T = the total gas consumption of all appliances (MJ/h)

The minimum vertical dimension of any free ventilation opening shall be 6mm

NOTE 1 When used in this Clause, the term 'directly to outside' means any one of the following options, provided that the ventilation path is unobstructed by building material or insulation:

(a) Directly through an outside wall (preferred option).
(b) Through to an outside wall but offset.
(c) Into a cavity ventilated to outside.
(d) Into an under floor space ventilated to outside.
(e) Into a roof space ventilated to outside.

NOTE 2 The two openings may be combined provided that the top and bottom of the opening reach the limits set by this Clause.

Natural ventilation via adjacent room

Two permanent openings shall be provided in the room or enclosure. The openings shall be located to ensure the distance between the top of the upper opening and the ceiling of the room or enclosure, and the distance between the bottom of the lower opening and the floor of the room or enclosure does not exceed 5% of the height of the room or enclosure.

The minimum free ventilation area provided by each opening shall be calculated using the following formula:

A=6×T

where

A = the minimum free ventilation area (cm ^2 )

T = the total gas consumption of all appliances (MJ/h)

These requirements shall apply to all subsequent rooms until a room is ventilated to outside, in accordance with the previous section, or the total input of the appliances does not exceed 3MJ / h for each cubic metre of the total volume of the enclosure and rooms.

The minimum vertical dimension of any free ventilation opening shall be 6mm

NOTE: The two openings may be combined provided that the top and bottom of the opening reach the limits set by this Clause.

• Liquid petroleum gas sinks to the floor as it is heavier than air. Therefore, rooms containing LPG cylinders must also be equipped with vents to allow gas to escape in the event of a leak. As a result LPG cylinders, whether partially or completely full, must not be installed or stored in rooms or storage areas that are below ground level (cellars, etc.). It is advisable to keep only the cylinder being used in the room, positioned so that it is not subject to heat produced by external sources (ovens, fireplaces, stoves, etc.) which could raise the temperature of the cylinder above 50^ .

Adjacent cabinetry

The location of connection points is given in the table on page 5. For trouble-free operation of appliances installed in housing units, the minimum distances shown in fig.4 should be observed. It is recommended that the adjacent kitchen surfaces should be capable of withstanding temperatures of 65^ . Also, the following must be observed:

• The appliance should be installed next to cabinetry which is no taller than the top of the cooker hob.
• The wall in direct contact with the back panel of the cooker must be made of non-flammable material. During operation of the cooker, the back panel of the cooker could reach a temperature of 50^ above room temperature.
• Kitchen cabinets installed next to the cooker that are higher than the top of the hob, must be at least 600mm from the edge of the hob itself.

• If the hood is installed below a wall cabinet, the latter must be at least 700mm (millimetres) above the surface of the hob.

• Cabinets installed adjacent to the hood must be at least 420mm above the hob,

The following minimum clearances to combustible materials must be observed:

Minimum clearance from edge of burner to side wall must be 200 mm.
- Minimum clearance from edge of burner to rear wall must be 55mm .

Range hoods

Range hoods and overhead exhaust fans must be installed according to manufacturers' instructions but in no case shall clearance from hob burners be less than 650~mm for range hoods and 750~mm for overhead exhaust fans.

• If the hood is installed below a wall cabinet, the latter must be at least 700mm (millimetres) above the surface of the hob.

Fitting the cooktop above an oven

When installing the cooktop above an oven, both the electricity supply cable and the gas pipe or flexible hose must not touch hot parts of the oven housing.

When installing above a built-under oven without forced cooling ventilation, suitable air vents should be provided for (inlet at least 200cm^2 from the bottom, outlet at least 120 cm^2 from the top part) to allow adequate ventilation inside the housing unit.

Also a wooden panel should be installed beneath the hob as insulation, positioning it at a minimum distance of 15mm from the hob housing.

Before the installation remove the grids and burners from the hob and turn it upside down, making sure you don't damage the thermocouples and spark plugs.

Apply the seals that come with the appliance along the outer edges of the hob to prevent any passage of air, humidity and water (see Figure).

For proper application make sure the surfaces to be sealed are clean, dry and free of any grease/oil.

• The installation cavity should have the dimensions indicated in the figure. Fastening hooks are provided, allowing you to fasten the hob to tops that are between 20 and 40mm thick. To ensure the hob is securely fastened to the top, we recommend you use all the hooks provided.

Hook fastening diagram

Front

Hooking position Back for top H=40mm

I Use the hooks contained in the "accessory pack".

• Where the hob is not installed over a built-in oven, a wooden panel must be installed as insulation. This must be placed at a minimum distance of 20mm from the lower part of the hob.

Ventilation

To ensure adequate ventilation, the back panel of the cabinet must be removed. It is advisable to install the oven so that it rests on two strips of wood, or on a completely flat surface with an opening of at least 45 × 560 ~mm (see diagrams).

Electrical connection

Hobs equipped with a three-pole power supply cable are designed to operate with alternating current at the voltage and frequency indicated on the data plate (this is located on the lower part of the appliance). The earth wire in the cable has a green and yellow cover. If the appliance is to be installed above a built-in electric oven, the electrical connection of the hob and the oven must be carried out separately, both for electrical safety purposes and to make extracting the oven easier.

Connecting the supply cable to the mains

Install a standardised plug corresponding to the load indicated on the data plate.

The appliance must be directly connected to the mains using an omnipolar circuit-breaker with a minimum contact opening of 3mm installed between the appliance and the mains. The circuit-breaker must be suitable for the charge

indicated and must comply with current electrical regulations (the earthing wire must not be interrupted by the circuitbreaker). The supply cable must not come into contact with surfaces with temperatures higher than 50^

! The installer must ensure that the correct electrical connection has been made and that it is compliant with safety regulations.
Before connecting to the power supply, make sure that:
- The appliance is earthed and the plug is compliant with the law.
- The socket can withstand the maximum power of the appliance, which is indicated on the data plate.
- The voltage is in the range between the values indicated on the data plate.
- The socket is compatible with the plug of the appliance. If the socket is incompatible with the plug, ask an authorised technician to replace it. Do not use extension cords or multiple sockets.

! Once the appliance has been installed, the power supply cable and the electrical socket must be easily accessible.

! The cable must not be bent or compressed.
! The cable must be checked regularly and replaced by authorised technicians only (see Assistance).
! The manufacturer declines any liability should these safety measures not be observed.

Gas connection

Check The Gas Type

! Before installation, check that the gas type (natural gas or Universal LPG) of the cooker is suitable for the gas type available to the installation. It is extremely dangerous to use the wrong gas type with any appliance, as fire or serious injury can result.

This cooker is supplied from the factory already set for Natural Gas. To convert the cooker to LPG (or back to Natural Gas from LPG), follow the directions later in this section.

Fit regulator supplied for Natural Gas (if applicable) at rear of appliance, and as close as practicable to the appliance. It is recommended that an isolating valve and union be fitted, to enable simple disconnection for servicing. These are to be in an accessible location.

! Check that the pressure of the gas supply is consistent with the values indicated in Table 1 ("Burner and nozzle specifications"). This will ensure the safe operation and longevity of your appliance while maintaining efficient energy consumption.

Pipe or Hose Connection

This appliance is suitable for use with either a flexible connection or rigid copper connection.

Either a rigid metal pipe with fittings in compliance with the standards in force must be used for connecting to the nipple union (threaded 12 G male fitting) situated at the rear of the appliance to the right (fig.8), or an approved flexible hose of class B or D.

Should it be necessary to turn the fitting, the gasket (supplied with the appliance) must be replaced. If a flexible hose is used, it should be as short as possible with a maximum length of 1.2 metres;

• The flexible connection must be approved to class B or D of AS/NZS1869 as a minimum.
• it should not be bent, kinked or compressed;
• it should not be in contact with the rear wall of the appliance or in any case with parts which may reach a temperature of 50^ ;
• it should not come into contact with pointed parts or sharp corners;
• it should not be subject to any pulling or twisting forces;
• it should be easy to inspect along its entire length in order to be able to check its condition.
• The supply connection point must be accessible with the appliance installed.
• The inner diameters of the pipe are as follows:

8 mm for LPG;

13 mm for Natural Gas.

Checking the tightness of the connection

Upon completion of installation, check the gas circuit, the internal connections and the taps for leaks using a soapy solution (never a flame). Also check that the connecting pipe cannot come into contact with moving parts which could damage or crush it. Make sure that the natural gas pipe is adequate for a sufficient supply to the appliance when all the burners are lit

Duplicate Data Plate

Where the data plate is obscured by cabinetry when the cooker is in the installed position, place a duplicate data plate on a surface of the cabinetry adjacent to the cooker.

Adapting to different types of gas

To adapt the hob to a different type of gas other than default type (indicated on the rating plate at the base of the hob or on the packaging), the burner nozzles should be replaced as follows:

1. Remove the hob grids and slide the burners off their seats.
2. Unscrew the nozzles using a 7mm socket spanner, and replace them with nozzles for the new type of gas (see table 1 "Burner and nozzle characteristics").
3. Reassemble the parts following the above procedure in the reverse order.
4. Once this procedure is finished, replace the old rating sticker with one indicating the new type of gas used. Sticker are available from any of our Service Centres.

Replacing the nozzles on separate "double flame" burners

1. Remove the grids and slide the burners from their housings. The burner consists of 2 separate parts (see figure);
2. Unscrew the burers with a 7mm wrench spanner. The internal burner has a nozzle, the external burner has two (of the same size). Replace the nozzle with models suited to the new type of gas (see table 1).
3. Replace all the components by repeating the steps in reverse order.

Replacing the Triple ring burner nozzles

1. Remove the pan supports and lift the burners out of their housing. The burner consists of two separate parts (see pictures).
2. Unscrew the nozzles using a 7 mm socket spanner. Replace the nozzles with models that are configured for use with the new type of gas (see Table 1). The two nozzles have the same hole diameter.
3. Replace all the components by completing the above operations in reverse order.

• Adjusting the burners' primary air : Does not require adjusting.
• Setting the burners to minimum:
• Turn the tap to the low flame position;
• Remove the knob and adjust the adjustment screw, which is positioned in or next to the tap pin, until the flame is small but steady.

In the event of single-control DRDA (DCDR) burners, adjustment can be performed by intervening on the 2 screws located near the tap pin (see picture).

1. Having adjusted the flame to the required low setting, while the burner is alight, quickly change the position of the knob from minimum to maximum and vice versa several times, checking that the flame does not go out.
2. Some appliances have a safety device (thermocouple) fitted. If the device fails to work when the burners are set to the low flame setting, increase this low flame setting using the adjusting screw.
3. Once the adjustment has been made, replace the seals on the by-passes using sealing wax or a similar substance.

If the appliance is connected to liquid gas, the regulation screw must be fastened as tightly as possible.

! Once this procedure is finished, replace the old rating sticker with one indicating the new type of gas used. Stickers are available from any of our Service Centres.

! Should the gas pressure used be different (or vary slightly) from the recommended pressure, a suitable pressure regulator must be fitted to the inlet pipe (in order to comply with current national regulations).

Post Installation Checks

Perform post installation checks and ensure proper and safe operation before leaving. Test all burners individually and in combination.

Leak Check

• Ensure all gas control knobs are in the Off position.
• Ensure the gas supply is switched on.
• Spray a solution of soapy water onto all gas joints as well as the full length of any flexible hoses. UNDER NO CIRCUMSTANCES USE A NAKED FLAME IN CHECKING FOR LEAKS.

If bubbles appear anywhere, turn the gas supply off, check all connections and retest. If satisfactory operation cannot be achieved, contact place of purchase or their appointed agent for service.

Flame check

Turn each burner on, and ensure that the flame is blue with minimal yellow tipping. If there is significant yellow tipping, flame lift off or excessive noise, check pressure and adjust at the regulator if necessary.

If satisfactory operation cannot be achieved, contact place of purchase or their appointed agent for service.

Igniter operation

Check that the igniter for each burner successfully ignites the gas.

If an igniter fails to work, first remove the plug from the electrical power outlet, and then check that all the electrical connections are in place.

If satisfactory operation cannot be achieved, contact place of purchase or their appointed agent for service.

Low flame setting

Check the low flame setting for each hob burner to ensure that the minimum flame will not be extinguished by air draughts.

Light the burner.
- Turn the control until it engages in the minimum position.
- Ensure the flame is stable and will not be extinguished by air draughts.

To adjust the minimum flame:

Follow the procedure described in the gas conversion instruction.

Start-up and use

The position of the corresponding gas burner or electric hotplate* is shown on every knob.

Gas cooker hobs are equipped with discrete power adjustment that allows for accurately adjusting the flame to 5 different power levels. Thanks to this system, gas hobs are also capable of guaranteeing the same cooking results for each recipe, as the optimal power level for the desired type of cooking can be identified in an easier, more accurate way.

Gas burners

Each burner can be adjusted to one of the following settings using the corresponding control knob:

• Off

Maximum

Minimum

To light one of the burners, hold a lit match or lighter near the burner and, at the same time, press down and turn the corresponding knob anti-clockwise to the maximum setting. Since the burner is fitted with a safety device, the knob should be pressed for approximately 2-3 seconds to allow the automatic device keeping the flame alight to heat up. When using models with an ignition button, light the desired burner pressing down the corresponding knob as far as possible and turning it anticlockwise towards the maximum setting.

If a flame is accidentally extinguished, turn off the control knob and wait for at least 1 minute before trying to relight it.

To switch off the burner, turn the knob in a clockwise direction until it stops (when reaches the "●" position).

Discrete flame adjustment

The selected burner can be adjusted - by means of the knob to 5 different power levels. To shift between levels, simply turn the knob towards the desired power level.

A click signals the passage from one power level to the other.

The selected power level is indicated by the corresponding

symbol (symbols) and, on hobs equipped with a display, by the LEDs that turn on (5 = max. power; 1 = min. power). The system guarantees accurate flame adjustment and uniform cooking

results by facilitating selection of the desired power level.

The "double-flame" burner

This gas burner consists of two concentric flame rings that can operate jointly or independently (in case of dual-control only).

As the burner is fitted with a safety device, the knob should be pressed down for approximately 2-3 seconds until the device keeping the flame automatically alight heats up.

Dual control:

Each ring comprising the burner has its own control knob: The knob marked with the symbol controls the outer ring. The knob marked with the symbol controls the inner ring.

To activate any one of the two rings, press the corresponding knob and turn it anti-clockwise to the maximum power

setting

In order to use the double-flame burner to its full potential, avoid simultaneously setting the inner ring to minimum power and the outer ring to maximum power.

Single control:

The rings comprising the burner are activated through a single control knob.

To simultaneously turn on both rings, position the knob on

the symbol max) - (min) then press and turn the knob anti-clockwise.

To turn on the inner ring only, position the knob on the symbol

(max) - min) then press and turn the knob clockwise.

(to switch modes, it is necessary to switch off the burner).

To switch off the burner, press and turn the knob clockwise until it stops (when it reaches the "●" position).

Practical advice on using the burners

To ensure the burners operate efficiently:

• Use appropriate cookware for each burner (see table) so that the flames do not extend beyond the bottom of the cookware.
  Always use cookware with a flat base and a cover.
• When the contents of the pan reach boiling point, turn the knob to minimum.
