■
■
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
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.

Installation and connection
Converting the cooktop from Nat. Gas to
Universal LPG
All work involved in installation, setting and adaptation
to a different gas type must be carried out by
authorised personnel from our Service Centre and must
comply with current regulations and the conditions laid
down by the local gas company.
Before conversion the cooktop must be disconnected
from the electricity and gas valves must be turned to the
OFF position.
Important: After finishing, stick the sticker, indicating
the new gas type, close to the specifications plate.
Adjusting the gas valves
1. Turn the control knobs to the lowest setting.
2. Remove the control knobs from the gas valves. A
flexible rubber sealing ring will be visible. Push down
with the tip of a screwdriver on the gas valve's
setting screw.
Never remove the sealing ring. Sealing rings
prevent liquids and dirt from finding their way into
the appliance and impairing its ability to function
properly.

1. Remove all pan supports, burner caps and
distributors.
2. To replace the injectors, use the key that is available
from our technical service with code 340847 (for
double-flame burners 340808). See table. It is
important to make sure that the injector does not
become detached during removal or fastening. They
must be properly tightened to ensure that there are
no leaks.
With these burners, there is no need to adjust the
primary air.
3. Fasten the distributors and burner caps to the
corresponding burners. In addition to this, put the
pan supports in place on the corresponding burners.
3. 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:
1. Remove all pan supports, burner caps, diffusers and
control knobs.
2. Loosen the screws on the burners.
3. 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 gas tap axle. In the event of damage,
the gas valve must be completely replaced.

Automatic ignition
If your appliance has automatic ignition (ignition plugs):
1. Press the control knob for the selected burner and
turn it anticlockwise to the highest power setting.
Sparks are produced on all burners while you are
pressing and holding the control knob. The burner
ignites.
2. Release the control knob.
3. Turn the control knob to the required position.
If the burner does not ignite, switch it off and repeat the
steps described above. This time, hold the control knob
down for longer (up to 10 seconds).
If the burner does not switch on after 15 seconds,
switch off the control knob and open the door or
window in the room. Wait at least a minute before
igniting the burner again.
Note: It is important to keep the appliance clean. If the
ignition plugs are dirty, this may cause ignition faults.
Clean the ignition plugs regularly with a small nonmetallic brush. Take care to prevent the ignition plugs
from suffering any heavy knocks.
Safety system
Your hob is equipped with a safety system
(thermocouple) that cuts off the gas when the burners
are accidentally switched off.
To ensure that this device is active:
1. Switch on the burner as usual.
2. Without releasing the control knob, press and hold it
down firmly for 4 seconds after lighting the flame.
Switching off a burner
Turn the corresponding control knob clockwise to the 0
setting.
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.
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.

Instructions 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 recommendations can help you save
energy and avoid damaging your cookware:
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.
Cleaning and maintenance
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.
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.

2Cleaning and maintenance
Cl eani ng and mai nt enance
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.
■
If your hob is fitted with a glass or aluminium panel,
never use a knife, scraper or similar implement to
clean the point where it joins the metal.
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.
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 464524)
is used regularly.
Caution!
The stainless steel cleaner must not be used in the area
around the controls. The (printed) symbols may be
wiped off.
Do not leave acidic liquids (e.g. lemon juice, vinegar,
etc.) on the hob.
