Connection
Fig. 4
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 note:
This appliance is connected to the mains (240 VAC) by
means of the connecting lead which must be fixed to the
kitc he n unit to p reve nt i t fro m c o ming in t o con ta c t wit h h o t
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.
Important: 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. Fig. 4.
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 as per Fig. 5. and Fig. 6.
Direction of gas flow is indicated on the rear of the
regulator.
For position of the inlet connection refer Fig.1.
Use pipe compound or thread sealant, properly theaded
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.
10
Page 10
Fig. 5
Fig. 6
There are two ways to carry out the connection to the
main gas line:
A. The hotplate can be connected with rigid pipe as
specified in AS/NZS 5601.1
B. Flexible Hose: If installing with a hose assembly, install
with a hose assembly that complies with AS/NZS 1869
(AGA Approved), 10 mm ID, class Bor D, no more than
1,2 m long and 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
underbench oven.
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.

guarantee the seal.
Adjustment of the
taps
Set the control knobs to minimum.
Remove the control knobs from the taps. Fig. 9.
It has a flexible rubber valve reinforcing ring. Simply press
on this seal with the tip of a screwdriver to allow access
to the tap adjusting screw.
Never remove the valve reinforcing ring.
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
quickcly 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 splash 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 the grease
splash tray:

Technical Assistance Service. To release the front clips,
apply the lever to the area shown in figure 10.
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.
These devices are essential for the correct operation of
the appliance as they prevent liquids and dirt from
entering the appliance.
Refit the control knobs.

automatically
If your cooktop can be switched on automatically (ignition
sparkers):
1. 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 (it is no longer
necessary to press down the control knob).
2. 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! 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
on.
Safety system Depending on the model, your cooktop 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 and,
without releasing the control knob, press and hold it
down firmly for 4 seconds after lighting the flame. Fig. 15.
Switching off a burner Turn the corresponding control knob clockwise to the 0
setting.

Warnings It is normal to hear a slight whistling noise while the
burner is operating.
When it is 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.
A few seconds after switching off the burner, it will make
a sound (thud). 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.
An orange-coloured flame is normal. This is caused by
the presence of dust in the atmosphere, spilt liquids, etc.
The kitchen will become hot and humid when this gas
appliance is used. You must therefore ensure that the
kitchen is well ventilated: either keep the natural
ventilation apertures open, or install a ventilation system
(extractor hood).
If using the appliance intensively for prolonged periods,
you may require additional ventilation (e.g. by opening a
window) or more effective ventilation (e.g. by increasing
the cooktop's ventilation, if possible).
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 one minute.
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:
17
Page 17
Suitable pans
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).

progress and the burners will stay on. If the temperature
drops to acceptable levels, the • message will disappear.
If the temperatures reach the maximum permitted limits,
the timer will switch off all the burners on the hob as a
protective measure, and the display will alternately show
the• message and the times remaining for the
programmes that were in progress and have been
stopped. The controls will be locked until the temperature
falls and reaches acceptable levels.
Wait a few minutes before using your hob again.

Precautions for use
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
should not touch the sides of the pan.
Do not use damaged pans, which do not sit evenly on
the cooktop. 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 to avoid wasting energy.
Always place the pan right 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.
Pans should be placed on the cooktop carefully.
Do not strike the cooktop and do not place excessive
weight on it.
Make sure that the pan supports and burner covers are
correctly positioned before using the appliance.

Unsuitable products Do not use steam cleaners. This could damage the hob.
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 covers are correctly placed on the diffuser.
If y our hob is f itt ed w ith a gl a ss o r al umi niu m pa nel , ne ver
use a knife, scraper or similar to clean the point where it
joins the metal.
Maintenance Always clean off any liquid as soon as it is spilt: you will
save yourself any unnecessary effort.
Do not leave acidic liquids (e.g. lemon juice, vinegar, etc.)
on the hob.
Where possible, do not allow salt to come into contact
with the surface of the electric hob.
The ring cover of the double or triple flame burner and
stainless steel parts such as hotplate rings, top sheet and
the area around the burners may become discoloured
over time. This is normal because of the high
temperatures. Each time the appliance is used these
parts should be cleaned with a product that is suitable for
stainless steel.
The stainless steel cleaner must not be used in the area
around the controls. The (printed) symbols may be wiped
off.
