GAS CONNECTIONS
LOCAL AUTHORITY REQUIREMENTS
Check Gas Type and specifications plate placed on the bottom face of the unit. All gas fitting work, service and
repairs can only be performed by an authorized person in accordance with the current edition of AS/NZS5601 and
local gas regulations. Failure to comply with this condition will render the warranty invalid. Always unplug the
appliance before carrying out any maintenance operations or repairs. The walls of the units must not be higher
than work top and must be capable of resisting temperatures of 75 above ambient temperature. Do not install the
appliance near flammable materials (e.g. curtains). The final act of any installation or gas type conversion must be
the full testing of this appliance, which includes leak testing, ignition of each burner and the functionality of the
burners separately and together.
INSTALLATION
The appliance is predisposed and adjusted to operate with the gas indicated on the specifications plate (normally
NG) applied onto the appliance. Please see gas rates summary information on the previous page.
If the appliance must be operated with a gas different than that indicated on the plate, it is necessary to execute the
following operations:
-Gas connection including regulator (NG) to be changed.
-Replacement of the injectors.
-New gas label attached stating gas type.
-Adjustment of minimum setting.
-Check (and adjust if necessary) the gas pressure using a manometer connected to 6mm rubber tubing.
GAS CONNECTION
The connection must be made by a qualified gas fitter according to the relevant standard. The gas connection is
positioned 40mm from the left hand side (from front), 30mm in from the back edge.
The fitting is made up of one elbow and one gasket (fitted between the inlet and elbow).
The hob must be installed in a room with adequate ventilation (see installation section).
N.G.:
Fit the supplied NG regulator to the elbow fitting using two spanners (note orientation of the NG regulator gas flow).
Connect the other side of the NG regulator to the gas inlet pipe with the correct ½” BSPT thread connector using
two spanners.
UNIVERSAL L.P.G.:
Connect the cooking hob inlet to the gas inlet pipe with the correct ½” BSPT thread connector (or using the
appropriate adaptor) using two spanners. Connect the other end of the pipe to the cylinder pressure regulator.
ORIENTATION OF THE ELBOW
The appliance is supplied with a gas connection oriented towards the centre of the cooking hob. The connection to
the gas supply must be affected only from this side or in vertical position by turning the elbow downwards. To turn
the elbow, first loosen the nut. Adjust the position of the elbow to the final position and retighten the nut. Make sure
that there are no leakages by testing with a soapy solution and brush.
IMPORTANT:
Never attempt to turn the elbow without having first slackened off the relative lock nipple.
It is recommended that the seal be replaced when it begins to show even the slightest deformation or imperfection.
After connecting to the gas supply, check that the couplings are correctly sealed, using soapy solution and a brush,
but never a naked flame.
Where a flexible hose assembly is used, ensure it is approved to AS/NZS 1869, Class B Ø10mm, and no longer
than 1m. Any hose assembly must be restrained from accidental contact with the flue outlet of an under-bench
oven.
OPERATIONS TO BE PERFORMED WHEN CONVERTING GAS TYPES
This operation can only be performed by an authorized person.
Remove the gratings and the burner covers;
Using a spanner, replace the nozzle injectors “J” (Fig.20) with either Natural Gas sized
injectors or ULPG sized injectors.

CHECKING THE BURNER PRESSURE
Natural Gas (the appliance test point is located at the
regulator). The supplied regulator must be fitted to the
appliance inlet connection. The gas pressure must be
adjusted to 1.0kPa when approximately 50% of the
burners are on high.
Universal LPG (the appliance test point is located
at the injector). The gas pressure must be
checked to confirm the appliance operating
pressure is 2.75kPa. The appliance test point is
the rapid burner injector.
1. Disconnect the electrical power.
2. Light the auxiliary burner and set to high. Make
sure all other burners are off.
3. Zero the manometer, fix the flexible tubing to
seal around the rapid burner injector and hold in
place. Check the gas pressure by pressure by
pressing in the corresponding burner control knob
down and turning to the high position.
4. If the pressure is 2.75kPa, reassemble the burner and perform the final checks as per this manual.
5. If the pressure is not 2.75 kPa, disconnect the appliance and check/adjust/replace the ULPG cylinder regulator(s)
as appropriate in accordance with AS/NZS 5601.
Alternatively, if the appliance is supplied with a ULPG test point adapter, then this can be fitted to the inlet
connection for the purpose of a test point.
REGULATING THE BURNER MINIMUM SETTING
When switching from one type of gas to another, the
minimum flow rate must also be correct. The flame
should not go out even when passing suddenly from
maximum to minimum flame. To regulate the flame,
follow the instructions below:
Light the burner
Set the gas valve to minimum
On gas valves provided with adjustment screw in the
centre of the shaft (fig.21)
Using a screwdriver with max. diameter 3mm, turn the
screw inside the tap until the correct setting is obtained.
On gas valves provided with adjustment screw on the valve body (fig.22):
Turn the screw “A” to the correct setting with a screwdriver.
LUBRICATION OF THE GAS TAPS
This can only be performed by an authorised person. It may be required if the gas taps become stiff and difficult to
turn.
LEAK TESTING
1. Make sure gas control knobs are Off and turn the cylinder valve On.
2. Check for leaking joints by brushing with solution of half-liquid detergent and half water. If a leak is present,
bubbles will appear (or you may hear a hissing sound). Retightening connections can generally repair a
leaking joint. You must also check the gas hose and connection at the gas cylinder. If a leak cannot be
resolved, do not proceed.
DO NOT USE NAKED FLAME FOR LOCATING GAS LEAKS.
IF A LEAK PERSISTS CALL AN AUTHORISED GAS FITTER.
NOTE: If an appliance cannot be adjusted to perform correctly, contact your nearest service department.

ELECTRICAL CONNECTIONS
LOCAL AUTHORITY REQUIREMENTS
Installation is only permitted by an authorized person, and carried out according to instructions provided by the
manufacturer. Incorrect installation might cause harm and damage which the manufacturer accepts no
responsibility. The electrical connection can be found 30mm in from the rear edge and 280mm from the left hand
side (looking from the front).
INSTALLATION
This cooktop must be connected to a 220-240V 50Hz power supply. It is earthed via the cord.
Before carrying out the connection 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 hob’s power rating (also indicated on the identification
plate);
The power point must be connected to a suitable earth wiring, in conformity to current safety regulations.
Ensure that the power supply is within 900mm of the cooktop. The power supply cord must not touch against any
hot surfaces and must be placed so that its temperature does not exceed 75 degrees C at any point along its
length.
The colours of the wires in the hob power cable may not correspond with the colours marked on the terminals of
your electrical plug. The plug should in any case be wired as follows:
—connect the green/yellow wire to the terminal marked with the letter E or the
earth symbol or coloured green/yellow;
—connect the blue wire to the terminal marked with the letter N or coloured black;
—connect the brown wire to the terminal marked with the letter L or
coloured red.
After having installed the appliance, the power switch or power plug must always
be in an accessible position.
Electrical connection diagram
N.B For connections to the mains power supply, never use adapters, reductions or multiple power points as these
may overheat and catch fire.
In the event that installation should require modifications to the mains supply wiring system or if the power plug is
not suitable for the type of power point available, it is required that a qualified technician be called to carry out
substitution.
The technician will also have to verify that the cross-section of the electric cables on the power point match the
appliance’s power rating.
INSTALLATION
Note: These tops are designed to be fitted into kitchen fixtures measuring 600 mm in depth.
In order to install the cooker top into the kitchen fixture, a hole with the dimensions shown on the cutting size board
has to be made, keeping in consideration the following:
Within the fixture, between the bottom side of the cooker top and the
upper surface of any other appliance or internal shelf there must be a
clearance of at least 30 mm;
Keep at least 200mm from the periphery of the burners to any side or rear
wall with combustible surfaces or keep the appliance sides at least 50mm
from walls with non-combustible surfaces.
There must be a distance of at least 650 mm between the hob and any
extractor hood or wall cupboard positioned immediately above it. The
distance to an overhead exhaust fan must be at least 750mm.
The duplicate data plate should be fixed in an accessible position close to
the appliance (inside face of cupboard door, side of cabinet etc).
Note: Keep a safe distance away from combustible constructions.
After installation, all burners should be tested individually and together to
ensure correct operation.
7

INSTALLATION IN KITCHEN CABINET WITH DOOR
The fixture must be made according to specific requirements in order to prevent
the gas burners from going out, even when the flame is turned down to
minimum, due to pressure changes while opening or closing the cupboard
doors.
When the hob is installed above a cupboard with doors, a separate panel must
be installed underneath it. Leave a gap of at least 30 mm clearance between
the cooker top and the surface of the panel (fig.13), which must be easily
removable to allow sufficient access for any servicing procedures. NOTE:
When installing above a cupboard, a dividing shelf (as above) must be
installed. If installed above an under-bench oven, this is not required.
Installation of an oven without a cooking fan underneath the hob is forbidden.
PREPARING & PLACING THE HOB FOR INSTALLATION
Every cooker top is provided with a set of tabs for
fitting to the unit with thickness from 3 to 4 cm and
a seal with adhesive on one side.
-Remove burners and grids.
-Turn the cooker top over and rest the top face on
a cloth.
-Apply the self-adhesive seal “G” as illustrated in
(fig.14).
-Slot the cooker top into the unit and position.
-Position the cooker top in the recess and secure
by means of the brackets as shown in fig.15 (for 3
or 4 cm thick work top).
DISCHARGING PRODUCTS OF COMBUSTION
Extractor hoods connected directly to the outside must be provided, to allow the products of combustion of the gas
appliance to be discharged (fig.16).
If this is not possible, an electric fan may be used, attached to the external wall or the ceiling above the cooktop.
The fan should have a capacity to circulate air at an hourly rate of 3-5 times the total volume of the kitchen (fig.17).

OPERATING INSTRUCTIONS
IGNITING THE BURNERS
The knob on your gas cooktop controls both ignition and the safety device. Proceed as follows to ignite the burners:
Press down & turn the knob for the burner you would like to use. Keep the knob strongly pressed in for
approximately 1 second to allow the ignitor to light the gas, and allow the thermocouple to heat up. Release the
knob after approximately 1 second. The flame can be adjusted by turning the knob anti clockwise until it reaches
the desired size. Only turn the knob between the High and Low settings, otherwise the burner will turn off.
To turn off the burner, push down & rotate the knob around to the ‘Off’ position.
Note: If the burner does not light within 12-15 seconds, turn the control knob back to the ‘Off’ position, and attempt
re-ignition after 1 minute. This will allow any unburned gas to escape from the burner area.
If the burner does not light, firstly check that the cooktop is connected to electricity. If connected ensure that the gas
is turned on and that the electrodes are sparking.
Also ensure that all burner caps are placed correctly on the burner rings.
USING THE BURNERS
For greater efficiency and less gas consumption, use pots and pans with the right diameters for the burners. Avoid
having flames extending out from underneath the pans (refer to the table in the appliance details section for
recommended sizing).
When cooking, always try to use a pot or pan with a flat base. Pots & pans with an uneven or curved base will
cause the burner to run inefficiently and will take longer to cook your food.
Always heat the water to boiling point before placing food items to be cooked. After the water has boiled, the heat
setting can be dropped to maintain the desired cooking temperature. This will speed up the cooking time and is
more efficient.
In the event of a power outage, your gas cooktop can still be used. Press & turn the desired knob to the ‘High’
position and light with a match. Depress the knob after ~3 seconds and continue to operate the burner.
Large utensils exceeding the recommended size can cause excessive heat to reflect back onto the appliance,
potentially damaging the appliance and causing a temperature hazard.
AUTOMATIC SAFETY VALVES
This safety device automatically closes the gas valve if there is any disruption of the gas flow to the appliance, or
if the gas flame goes out.
CLEANING AND STORAGE
Please follow the maintenance & cleaning guidelines below to keep your Blanco cooktop in good working order.
The cooktop should be cleaned regularly with all stains and boil overs being cleaned up. Do not allow stains and
boil overs to become burnt onto the appliance.
Please ensure the cooktop is cold when cleaning, to avoid burns from hot components.
Try to minimise the use of specialized cleaning products. Attempt to clean with soapy water and a sponge. If this is
not successful, a mild cleaner can be used.
Do not use abrasive cleaners or scourer type pads to clean the appliance. These can damage the Stainless Steel
finish.
A stainless steel cleaner can be applied which gives the cooktop an extra shine. Only apply after cleaning with
soapy water.
Avoid leaving acidic or alkaline substances on the cooktop.
Burners and enamelled components are only to be washed with soapy water & sponges. Do not use abrasive
cleaners on these components.
When cleaning burner components, please ensure that they are fully dry before re-placing on the cooktop and
before use.
Ensure that all components are placed back onto the cooktop correctly. Failure to do so can cause problems with
the burners igniting and functioning correctly. See diagrams on the following page for how to put the burners back
together.

WOK BURNER MAINTENACE & ASSEMBLY
When fitting the wok burner together, it is very important to check that the burner flame
distributor (F) and the cap (C) are correctly positioned (fig. 6). Failure to do so can
cause problems with ignition and also the way in which the burner operates.
Check that the electrode (S) is always clean to ensure trouble-free sparking.
Check that the probe (T) is always clean to ensure correct operation of the safety
valves (for models with safety device).
The Wok burner must be correctly positioned (see fig.7). The burner rib must lock into
position on the assembly below. If positioned correctly, the burner will not rotate (fig.8).
Then position the enamel cap A and the enamel ring B (fig.8).
The four holes around the outside of the crown must always be kept clean.
When cleaning, remove the flame divider (fig.9) and use a cotton bud, toothbrush, or a
stiff wire brush to clean out any incrustations or dirt from the four holes marked “H”
(fig.10).
This procedure is necessary to ensure the burner functions correctly.
MAINTENANCE
Clean burner tops and trivets at least once a week, or after any spillage. Check injectors are not blocked and the
electrode and probe are clean.
Gas inlet pipes should be checked periodically for leakages (see section on leak testing) a minimum of every 12
months.
Lubrication of gas valves - This can only be performed by an authorised person. It may be required if the gas tap
become stiff and difficult to turn.
