6. USING THE HOB
6.1 Gas hob
Before lighting the hob burners check that the flame diffuser rings are
correctly in place with their respective burner caps, making sure that the
holes Ain the flame diffusers are aligned with the plugs and
thermocouples.
For the dual burner UR2, place the burner caps Gand Fon the burner D,
ensuring that they fit snugly. The burner must then be placed on and fitted
into the base B(taking care to use the pin Cas reference). The pan stand
Bsupplied is for use with woks.
The special pan stand His for use with woks.
The burner controlled by each knob is shown next to
the knob. The appliance is equipped with an
electrical ignition device. Simply press the knob and
turn it anti-clockwise to the maximum flame symbol,
until the burner lights. If it does not light in the first 15
seconds, position the knob on 0 and wait at least 60
seconds before trying to light it again.
On valved models, once the burner is lit, keep the knob pressed for a few
seconds to give the thermocouple time to heat up. The burner may go out
when the knob is released: in this case, the thermocouple has not heated
up sufficiently. Wait a few moments and repeat the operation keeping the
knob pressed for a longer time. This is not necessary on burners that are
not equipped with thermocouple. Once the burner is lit, the flame can be
adjusted as needed. Always check that the control knobs are in the (off)
position when you finish using the hob.
If the burners should go out accidentally, after about 20 seconds a safety
device will be tripped, cutting off the gas supply, even if the gas tap is
open. In this case, turn the knob to the OFF position and wait at least 60
seconds before trying to light the burner again.

Instructions for the user
6.2 Practical tips for using the burners
For better burner efficiency and to minimise gas consumption, use pans
with a flat, smooth base and a lid that have a suitable size for the burner,
thus avoiding that the flames reach the sides of the pan (see point "6.3
Pan diameters"). Once the contents come to the boil, turn down the flame
far enough to prevent the liquid from boiling over.
To prevent burns or damage to the hob during cooking, all pans or griddle
plates must be placed inside the perimeter of the hob.
Take the greatest care when using fats or oils since they may catch fire if
overheated.

Warning:
At the end of cooking using pans with aluminium bases you may find white
residues on the cast iron pan stands. These residues are usually caused
by the pan base rubbing against the pan stand and are difficult to remove
with normal cleaning. Using abrasive or excessively aggressive products
to clean the pan stand could damage its enamel surface.

Instructions for the user
7. CLEANING AND MAINTENANCE
NEVER USE A JET OF STEAM FOR CLEANING THE APPLIANCE.
Before performing any operations requiring access to powered
parts, switch off the power supply to the appliance.
7.1 Cleaning stainless steel
To keep stainless steel in good condition it should be cleaned regularly
after use. Let it cool first.
7.1.1 Ordinary daily cleaning
To clean and preserve the stainless steel surfaces, use only specific
products that do not contain abrasives or chlorine-based acids.
How to use: pour the product onto a damp cloth and wipe the surface,
rinse thoroughly and dry with a soft cloth or deerskin.
7.1.2 Food stains or residues
Do not use metallic sponges or sharp scrapers: they will
damage the surface. Use ordinary non-abrasive products for
cleaning steel, with the aid of wooden or plastic utensils if
necessary. Rinse thoroughly and dry with a soft cloth or
deerskin.
7.2 Cleaning the gas components
For easier cleaning the pan stands, burner caps,
flame spreader crowns and burners can all be
removed; wash them with warm water and a non-
abrasive detergent making sure to remove any
encrustation and wait until they are perfectly dry.
Replace the burner caps on their corresponding
crowns, making sure that the slots A are centred
with the burner pins B.
For correct operation the igniters and thermocouples must
always be perfectly clean. Check them frequently and clean
them with a damp cloth if necessary. Remove any dry
residues with a wooden toothpick or a needle.

9. GAS CONNECTION
Before installation, make sure that the local distribution conditions (nature
and pressure of the gas) and the state of regulation of the appliance are
compatible.
Connection to the gas supply network can be made using a rigid copper
hose or a flexible steel hose with a continuous wall and in compliance
with the guidelines established by the standard UNI-CIG 7129.
Once the operation is complete, check the hose fittings for leaks using a
soapy solution; never use a flame. The cooker hob is preset for natural
gas G20 (2H) at a pressure of 20 mbar.
For supplying it with other types of gas, see chapter "10. ADAPTATION TO
DIFFERENT TYPES OF GAS".
The gas inlet connection is threaded ½” external gas (ISO 228-1).
Connection with rigid copper
hose: The connection to the gas
supply network must be carried out
in such a way that it does not cause
stresses of any type on the
appliance. The connection can be
made using the adapter unit D with
double cone, always inserting the
supplied gasket C in between.
Connection with flexible steel
hose: Use only continuous wall
stainless steel hoses that comply
with standard UNI-CIG 9891, making
sure to always insert the supplied
gasket C between the connection A
and the flexible hose B.
Installation with the flexible hose must be carried out so that the length of
the piping does not exceed 2 metres fully extended; make sure that the
hoses do not come into contact with moving parts and that they are not
crushed in any way.
9.1 Connection to liquid gas
Use a pressure regulator and make the connection on the gas cylinder
following the guidelines established by the regulations in force.
Make sure that the supply pressure complies with the values indicated in
the table at point "10.2 Burner and nozzle characteristics table".

9.2 Room ventilation
The appliance may only be installed in permanently ventilated rooms, as
specified by the standard UNI-CIG 7129 / 7131. In the room where the
appliance is installed, there must be an adequate air flow to meet the
requirements of normal gas combustion and the necessary ventilation of
the room itself. The air vent, protected by grilles, must be suitably
dimensioned (UNI CIG 7129 / 7131) and positioned so that no part of it is
obstructed, even partially. The room must be kept adequately ventilated in
order to eliminate the heat and humidity produced by cooking: in
particular, after prolonged use, it is recommended to open a window or to
increase the speed of any ventilators.
9.3 Extraction of the products of combustion
Extraction of the products of combustion must be ensured by means of
hoods connected to a natural draught chimney whose efficiency is
assured or via forced extraction. An efficient extraction system requires
precision planning by a specialist qualified in this area and must comply
with the positions and distances indicated by the regulations. When the
job is complete, the installer must issue a certificate of conformity.

11. FINAL OPERATIONS FOR GAS APPLIANCES
After making the adjustments described above, reassemble the appliance
by following the instructions in point "10.1 Replacement of nozzles on the
cooker hob" in reverse order.
After adjustment with a gas other than the preset one, replace the label on
the casing of the appliance with the label corresponding to the new gas.
This label can be obtained from the nearest Authorised Service Centre.
11.1 Adjusting the minimum for town and natural gas
Light the burner and turn it to the minimum
position. Extract the gas tap knob and turn the
adjustment screw inside or next to the tap rod
(depending on the model) until the correct
minimum flame is achieved. Refit the knob and
verify that the burner flame is stable (turning the
knob rapidly from the maximum to the minimum
position the flame must not go out). Repeat the
operation on all the gas taps.
11.2 Adjusting the minimum for liquid gas
To adjust the minimum with liquid gas, you must fully tighten the screw
inside or next to the tap rod (depending on the model) in a clockwise
direction. The bypass diameters for each individual burner are shown in
the table "10.2 Burner and nozzle characteristics table".
11.3 Lubrication of gas taps
Over time the gas taps may become difficult to turn and get blocked. Clean
them internally and replace the lubrication grease. This operation must
be carried out by a specialised technician.
