Warnings
Do not allow the flame to extend beyond the edge of the cooking utensil. This
instruction is based on safety considerations.
Do not forget that the unit becomes hot when in use.
Common sense is important. Just because the flame is out, does not mean parts
cannot still be hot.
This appliance shall not be used for space heating. This instruction is based
on safety considerations.
Be sure to disconnect the electrical supply before disassembly of the
appliance.
Keep the appliance area clear and free from combustible materials, gasoline
and other flammable vapours and liquids.
This appliance must be installed in a position with the proper level of
ventilation. Do not obstruct the flow of combustion and ventilation air.
Cabinets installed above the gas cooktop must have a minimum clearance of 650
mm (24”).
The gas pressure regulator supplied with the appliance must be installed in
line with the gas pipe. (N.G. only).
For pressure testing in excess of 3.5 kPa (1/2 psig) the appliance and its
individual shutoff valve must be disconnected from the gas supply piping
system.
Important. When using a very large pot, leave a gap of at least 50 mm (2”) to
avoid damaging any parts in bench top wood, plastic or other non-heat
resistant materials. Never leave oil or hot fat unattended.
The surfaces on heating and cooking appliances get hot when in use. Be
careful. Keep children away from the appliance.
Only use your appliance for the preparation of food and never for room-heating
purposes.
This appliance leaves the factory set for the gas supply indicated on the data
label. Call the Service Centre if it needs to be altered.
Do not tamper inside the appliance. If necessary, call your local Service
Centre.
Overheated fat or oil can easily catch fire. Never leave the appliance
unattended when cooking food with fat or oil, e.g. chips.
Never pour water on burning fat or oil. DANGER OF BURNS! Cover the receptacle
to smother the flames and turn the cooktop off.
If the liquefied gas bottle is not upright, liquefied propane/butane can enter
the appliance. Intense darting flames may therefore escape from the burners.
Components may become damaged and start to leak over time so that gas escapes
uncontrollably. Both can cause burns. Always use liquefied gas bottles in an
upright position.
In the event of a fault, cut the gas and electricity supplies to the
appliance. Call our Service Centre to repair the fault.
Do not use unstable or uneven-based receptacles on cooking plates or burners.
They may accidentally tip over.
If a gas supply knob/valve jams, do not force it. Call your official Service
Centre immediately for them to repair or replace it.
The illustrations used in this booklet are only intended as a guide.
Grids become very hot during use. When operating the appliance control knobs,
take care not to make contact with the grids.
This appliance is not suitable for use in a marine craft, caravan or mobile
home.
This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless they have been given supervision or instruction concerning
use of the appliance by a person responsible for their safety.
Make sure you keep these instructions for use and assembly in a safe place, so
that you can hand them on with the appliance if it ever changes owner.

Installation and connection
Statutory requirements
This installation must conform with the following:
- Manufacturer’s Installation instructions
- Local Gas Fitting Regulations
- Municipal Building Codes
- Refer to AS/NZS 5601.1 for Gas Installations
- S.A.A. Wiring Code
- Local Electrical Regulations
- Any other statutory regulations
Preparing to install
Refer to AS/NZS 5601.1 for piping size details. These built-in cooktops are
intended to be inserted in a benchtop cutout.
Only an officially authorized technician should connect the appliance.
Before you begin, turn off the gas and electricity supply.
Before connecting the unit, check whether the local connection conditions (type of gas) are compatible with the unit’s setting. Observe any special conditions imposed by local suppliers (utilities). The specifications of this cooktop are stated on the data label located on the bottom of the cooktop base.
A duplicate data label is supplied for adhesion to an accessible location near the hotplate if the data label on the base of the hotplate cannot be accessed when the hotplate is installed.
Clearances
A range hood fitted above the top must be installed according to the
installation instructions for the range hood. A minimum distance of 650 mm is
required for a range hood and 750 mm for an exhaust fan.
Any adjoining wall surface situated within 200 mm from the edge of any hob
burner must be a suitable noncombustible material for a height of 150 mm for
the entire length of the hob. Any combustible construction above the hotplate
must be at least 650 mm above the top of the burner and no construction shall
be within 450 mm above the top of the burner.
A minimum depth of 50 mm from the top of the worktop surface must be provided
for the appliance.
If the base of the hotplate can be touched, a protecting shield must be
fitted.
The shield must be at least 10 mm from the lowest part of the hotplate and must be capable of withstanding the appliance temperatures. Minimum thickness of benchtop is 30 mm.
After installation of the shield the clearance around the top and sides of
shield will allow adequate ventilation. Ensure the side and top clearances are
not obstructed.
If an oven is positioned below the cooktop the barrier does not need to be fitted, but a space of 35 mm must be maintained between the underside of the cooktop and the top of the oven.
Installation of cooktop into the kitchen bench
Side clearances: If the distance measured from the periphery of the nearest
burner to any vertical surface is less than 200 mm, the surface shall be
protected in accordance with clauses 6.10.1.2 of AS/NZS 5601.1.
For cutout dimensions and clearances see Preparing to install.
Installation procedure:
The adhesive seal provided prevents leaks. Adhere it to the work surface
around the cut-out. It must be adhered around the edge of the area cut out
Fitting the appliance onto the kitchen unit:
-
Place the cooktop in the correct position then loosen each of the clips so that they all turn freely (it is not necessary to completely undo them).
-
Insert and centre the cooktop.
Press the sides of the cooktop until it is supported around its entire perimeter. -
Turn the clips and tighten them fully.
The position of the clips depends on how thick the work surface is.
Connection
Electrical
An electrical 10 amp socket needs to be within 1 m of the hotplate to allow electrical connection. The socket must remain accessible after installation of the appliance.
Important notes:
-
This appliance is connected to the mains (240 VAC) by means of the connecting lead which must be fixed to the kitchen unit to prevent it from coming into contact with hot parts of the cooktop (or an oven installed underneath) and remain accessible after installation of the cooktop.
When making this connection make sure that the lead cannot come into contact with hot parts of the cooktop. -
This appliance must be earthed. When connecting the cooktop ensure that the earth wire is connected first and that all wires are connected to the correct terminals.
Gas
During the planning stage, consider the position of supply connections.
The cooktop must be connected to the gas supply with upstream connection of an
isolation valve in accordance with the respectively valid regulations. We
recommend that the isolation valve be fitted prior to the cooktop to enable
isolation of cooktop from gas supply.
The valve must be easily accessible at all times.
To find out the factory set gas type, see bottom of cooktop next to gas
connection.
Remove plastic cap from gas supply line prior to installation.
Fit regulator (N.G.) or a test point (Universal LPG) directly to the R 1/2’’
connection.
Direction of gas flow is indicated on the rear of the regulator.
For position of the inlet connection refer Preparing to install:
Use pipe compound or thread sealant, properly the added pipes and careful assembly procedure so that there is no cross threading, etc., which might cause damage or leakage.
Make sure that all connections peformed are free of leakage. The manufacturer does not accept any liability for leakage on connections performed by the installer or if the L-tube is moved or twisted.
There are two ways to carry out the connection to the main gas line:
- The hotplate can be connected with rigid pipe as specified in AS/NZS 5601.1
- Flexible Hose: If installing with a hose assembly, it must comply with AS/NZS 1869, 10 mm ID, class B or D, no more than 1.2 m long and installed in accordance with AS/NZS 5601.1. Ensure that the hose does not contact the hot surfaces of the hotplate, oven, dishwasher or any other appliance that may be installed underneath or next to the hotplate. The hose should not be subjected to abrasion, kinking or permanent deformation and should be able to be inspected along its entire length with the cooktop in the installed position. Unions compatible with the hose fittings must be used and all connections tested for gas leaks
The supply connection point shall be accessible with the appliance installed.
WARNING: Ensure that the hose assembly is restrained from accidental
contact with the flue outlet of an underteach oven.
To set the pressure (NG 1.0 kPa) operate the wok and auxiliary burners on
full.
Before Leaving- Check all connections for gas leaks with soap and water. DO NOT use a naked flame for detecting leaks. Ignite all burners both individually and concurrently to ensure correct operation of gas valves, burners and ignition. Turn gas taps to low flame position and observe stability of the flame for each burner individually and all together. Adhere the duplicate data plate to an accessible location near the hotplate. When satisfied with the hotplate, please instruct the user on the correct method of operation. In case the appliance fails to operate correctly after all checks have been carried out, refer to the authorised service provider in your area.
It should be expressly noted that we cannot accept any liability for direct or indirect damage caused by wrong connection, leakage or improper installation. When being repaired, the appliance must always be disconnected from the mains supply; if required, notify our customer service.
Converting the cooktop from Nat. Gas to Universal LPG
To change injectors
All work involved in installation, setting and adaptation to a different gas
type must be carried out by authorized personnel from our Service Centre and
must comply with current regulations and the conditions laid down by the local
gas company.
Request change-over injectors from our customer service department (refer injector chart below for sizes).
Burner| Natural gas Hourly Gas Consumption (MJ)|
Injector mark| Universal LPG Hourly Gas Consumption
(MJ)| Injector mark
---|---|---|---|---
Auxiliary| 3,80| 90| 3,00| 50
Semi-rapid| 6,50| 118| 5,50| 67
Miniwok| 13,00| 118| 11,00| 68
Wok 4 kW| 15,00| 182| 13,50| 100
Before conversion the cooktop must be disconnected from the electricity and gas valves must be turned to the OFF position.
Changing the nozzles of the burners on the cooktop
- Remove the pan supports, burner covers and diffusers.
- Change the nozzles using the spanner provided by our Service Centre (code 340847, for double and triple flame burners code 340808), taking special care to ensure that the nozzle does not fall when it is removed from the burner or when fitted.
Ensure that it is completely tightened in order to guarantee the seal.
Adjustment of the taps
-
Set the control knobs to minimum.
-
Remove the control knobs from the taps. It has a flexible rubber valve reinforcing ring. Press with the tip of the screwdriver to access the tap’s adjusting screw.
Never remove the valve reinforcing ring. The valve reinforcing rings guarantee the weathertightness of the appliance’s interior from liquids and dirt, which might otherwise prevent its correct operation. -
Adjust the minimum ring setting by turning the by-pass screw using a flat head screwdriver.
To adjust the minimum flame for N.G. replace the control knob onto the spindle, light the gas and turn the control knob to the small flame position. Screw the adjustment screw anti-clockwise to estabilish a minimum stable flame position. The flame should remain alight and not burn back to the injector when the valve is turned quickly from ‘Full On’ to the “Minimum flame” position and back a few times. To adjust the minimum flame position for ULPG the screw must be fully tightened down clockwise.
If the by-pass screw cannot be accessed, disassemble the grease drip tray, which is fixed to the rest of the hob using a clip and screw mounting system. The following steps must be taken to remove it:
- Remove all pan supports, burner caps, diffusers and control knobs.
- Loosen the screws on the burners.
- To assemble the grease splash tray again, proceed in the reverse order to removal.
It is important that all the seals are refitted to form a seal.
Never remove the tap spindle. In the event of a malfunction, change the whole
tap.
Important: After finishing, stick the sticker, indicating the new gas type, close to the specifications plate.

Operation
Remove the plastic covering used to protect the stainless steel before using
the appliance (depending on the model). If any traces of adhesive remain on
the printed areas, remove them with a wet cloth.
There are indications to show which burner each control knob operates.
It is essential to ensure that all the burner parts and pan supports are
correctly installed for the appliance to work correctly. Do not swap the
burner caps around.
Switching on automatically
If your hob can be switched on automatically (ignition sparkers):
-
Press the chosen burner control knob and turn it anticlockwise to the maximum power setting.
While the control knob is still pressed down, sparks are produced on all burners. The flame ignites. Wait a few seconds. -
Release the control knob.
-
Turn the control knob to the required setting.
If it does not come on, turn the control knob to the off setting and repeat the steps above. This time, press and hold the control knob for longer (up to 10 seconds).
Warning – Risk of deflagration!
If after 15 seconds the flame does not ignite, switch off the burner and open
a nearby window or door. Wait at least one minute before trying to switch the
burner back on.
Safety system
Depending on the model, your hob may have a safety system (thermocouple) that
prevents the flow of gas if the burners accidentally switch off.
To ensure that this device is active:
- Switch on the burner as usual.
- Without releasing the control knob, press and hold it down firmly for 4 seconds after lighting the flame.
Switching off a burne r
Turn the corresponding control knob clockwise to the 0 setting.
Power levels
The progressive control knobs can be used to control the power needed, from
minimum to maximum power.
Setting|
| Control off
---|---|---
Large flame|
| Maximum capacity or aperture and electricity on
Economy flame|
| Minimum capacity or aperture
Warnings
It is normal to hear a soft whistling noise while the burner is operating.
When first used, it is normal for the burner to give off odours. This does not
pose any risk and does not indicate a malfunction. They will disappear in
time.
An orange-coloured flame is normal. This is caused by the presence of dust in
the atmosphere, spilt liquids, etc.
If the burner flames are accidentally blown out, switch off the burner
operating control knob and do not try to relight it for at least 1 minute.
A few seconds after the burner is switched off, a sound (thud) will be
produced. This is not a fault – this means that the safety device is no longer
operating.
Keep the burner as clean as possible. If the ignition sparkers are dirty they
will not light properly. Clean them periodically using a small non-wire brush.
Bear in mind that the ignition sparkers must not suffer any serious impacts.
Use “Large” setting to bring the pan to the boil, then adjust the flame
between “Large flame” and “Economy flame” to maintain the required pan
temperature.
Important:
The use of a cooktop leads to the production of heat and moisture in the
kitchen. For this reason make sure that the room is properly ventilated. Keep
natural ventilation openings, such as windows, open or provide a mechanical
ventilation device (e.g. a range hood or overhead exhaust fan). An orangy
flame is normal and simply indicates the presence of salt in the atmosphere
(from cooking). If the flame has yellow patches, this is not a fault (of any
kind).
Cooking recommendation

chocolate, jelly
-
Do not place anything, eg. flame tamer, asbestos mat, between pan and pan support as serious damage to the appliance may result
-
Do not remove the pan support and enclose the burner with a wok stand as this will concentrate and deflect heat onto the hotplate.
-
Do not use large pots or heavy weights which can bend the pan support or deflect flame onto the hotplate.
Cooking pans
Suitable pans
The chart below gives the correct pan usage for each burner.
Burner| Minimum diameter of the cookware base| Maximum diameter
of the cookware base
---|---|---
Wok burner| 22 cm| 30 cm
Semi-rapid burner| 14 cm| 20 cm
Auxiliary burner| 12 cm| 16 cm
The cookware must not overhang the edge of the hob.
You should only use cookware with a domed base if your cooktop features a wok
burner and the additional
wok grid. The additional wok grid must be correctly positioned.
Precautions for use
Note : When using certain pots or pans, a slight and temporary
deformation of the steel cooking surface may
occur. This is normal and does not affect the functionality of the appliance.
The following advice is intended to help you save energy and prevent pan damage:
-
Use pans which are the right size for each burner. Do not use small pans on large burners. The flame must not touch the sides of the pan.
-
Do not use damaged pans, which do not sit evenly on the hob. Pans may tip over. Only use pans with a thick, flat base.
-
Do not cook without using a lid and make sure the lid is properly fitted. This wastes energy.
-
Always centre the pan over the burner, not to one side. Otherwise it could tip over. Do not place large pans on the burners near the control knobs. These may be damaged by the very high temperatures.
-
Place the pans on the pan supports, never directly on the burner. Make sure that the pan supports and burner caps are correctly positioned before using the appliance.
-
Pans should be placed on the hob carefully.
Do not strike the hob and do not place excessive weight on it.
Cleaning and maintenance
Cleaning
Once the appliance is cool, use a sponge to clean it with soap and water.
After each use, clean the surface of the respective burner parts once they
have cooled down. If any residue is left (baked-on food, drops of grease
etc.),
however little, it will become stuck to the surface and more difficult to
remove later. The holes and grooves must be clean for the flame to ignite
properly.
The movement of some pans may leave metal residue on the pan supports.
Clean the burners and pan supports using soapy water and scrub with a non-wire
brush.
If the pan supports are fitted with rubber rests, ensure that these are also
cleaned. The rests may come loose and the pan support may scratch the hob.
Always dry the burners and pan supports completely.
Water droplets or damp patches on the hob at the start of cooking may damage
the enamel.
After cleaning and drying the burners, make sure the burner caps are correctly
positioned on the diffuser.
Caution!
- Do not remove the control elements when cleaning the appliance. The appliance may be damaged if moisture finds its way inside.
- Do not use steam cleaners. This could damage the hob.
- Do not put the burner components in the dishwasher.
Maintenance
Always clean off any liquid as soon as it is spilt. This will prevent food
remains from sticking to the hob surface and you will save yourself any
unnecessary effort.
Do not leave acidic liquids (e.g. lemon juice, vinegar, etc.) on the hob.
Due to the high temperatures endured, the wok burner and the stainless steel zones (grease drip tray, burner outline, etc.) can change colour. This is normal. After each use, clean these areas with a product that is suitable for stainless steel.
It is recommended that the cleaning product available from our Technical Assistance Service (code 311499) is used regularly.
