LIGHTINGTHEBURNERS

•

For easier lighting, proceed before putting a pan

on the pan support.

To light a burner, push in the relevant control knob and

turn it anti-clockwise to "maximum" position.

Upon ignition, keep the knob pushed down for about 5

seconds. This will allow the "thermocouple" (Fig. 1 lett.

D) to be heated and the safety device to be switched

off, otherwise the gas supply would be interrupted.

Then, check the flame is regular and adjust it as

required.

If you cannot light the flame even after several

attempts, check the "cap" (Fig. 1 lett. A) and the

"crown" (Fig. 1 lett. B) are in the correct position.

To put the flame out, turn the knob to the symbol l.

FO 0204

•

Always turn the flame down or put it out before

taking the pans off the burner.

l WARNING! The crystal lid can splinter when

overheated. Always ensure all the burners are

off before closing it.

l The lid (not provided) is meant to avoid dust to

settleonthehob, whenitisclosed, andtocollect

splashes of oil or fat, when it is open. Do not use

it for any other purpose.

l Always wipe off any splash of liquid before

opening the lid.

2.Cleaning and Maintenance

•

Disconnect the appliance from the electrical

supply, before carrying out any cleaning or

manteinance work.

GENERAL CLEANING

Wash the enamelled components with warm soapy

water. Never use abrasive cleaners

Frequently wash the "caps" and the "crowns" with hot

soapy water, carefully taking away any built-up of food.

If the marks are particularly difficult to remove, use

common non-abrasive cleaners or specific products.

Never use steel wool pads or acids.

AUTOMATIC IGNITION

The automatic ignition of the gas burners is obtained

through a ceramic "candle" and a metal electrode (fig. 1

lett. C). Keep these components well clean, to avoid

difficult lighting, and check that the burner crown holes

(lett. B) are not obstructed.

FO 2030

PAN SUPPORTS

The hobs are provided with enamelled pan supports (thin

and light - fig.2).To keep the pan supports in the right

position, they are hooked to a couple of special hinges

in the back of the hob.

Thanks to these hooks, you can lift the pan supports for

easier cleaning (fig. 2). To take the pan supports

completely off the hob, proceed as shown in fig. 3.

The pan supports are dishwasher proof.

FO 2238

Fig. 3

3. Periodic Maintenance

Periodically ask your local Service Centre to check the

conditions of the gas supply pipe and the pressure

adjuster, if fitted.

To ensure the good operation of the hob and its safety

features, it is necessary that the taps are periodically

lubricated.

l The periodic lubrication of the taps must be

carried out by qualified personnel, which you

must refer to also in case of malfunctioning.

4. Mainteinance - Technical Assistance

ORIGINAL SPARE PARTS

This machine, before leaving the factory, has been

tested and studied by many experts and specialists, in

order to give you the best results.

Any repair work which needs to be carried out should

be done with the utmost care and attention.

For this reason we reccomend that for any problem you

contact the dealer who sold it to you, or our nearest

authorized Service Centre, specifying the nature of the

problem and the particular model which you own.

6.Instruction for the Installer

l Thefollowinginstructionsaboutinstallationand

maintenance must be carried out by qualified

personnel in compliance with the regulation in

force.

GAS CONNECTION

Choose fixed connections or use a flexible pipe in

stainless steel.

If using flexible metallic pipes, be careful they do not

come in contact with mobile parts or they are not

squeezed. Use the same attention when the hob is

combinatedwithanoven.

l The side walls of the unit in which the hob is

going to be installed, must not exceed the height

of the working top.

l Avoid installing the appliance in the proximity of

inflammable materials (e.g. curtains, tea towels

etc.).

IMPORTANT - To ensure a correct operation, a saving

of energy and the long-life of the appliance, the voltage

pressure of the appliance must correspond to the

recommendedvalues.

l Theappliancemustbeelectricallydisconnected

before all interventions. If any electric supply to

the appliance is required to carry out the work,

ensureallthenecessaryprecautionsarefollowed.

7.Electrical Connection

The appliance is designed to be connected to 230 V

monophase electricity supply.

The connection must be carried out in compliance with

the laws and regulations in force.

Before the appliance is connected:

1) checkthatthemainfuseandthedomesticinstallation

can support the load (see the rating label);

2) check that the power supply is properly earthed in

compliance with the current rules;

3) check the socket or the double pole switch used for

the electrical connection can be easily reached with

the appliance built in the forniture unit.

Connecttheplug,abletosupporttheloadmarkedonthe

identification plate, to the cable, following the

recommendationgiveninFig.5.Theplughastobefitted

in a proper socket.

Ifconnectingtheappliancedirectlytotheelectricsystem,

it is necessary that you install a double pole switch

between the appliance and the electricity supply, with a

minimumgapof3mm. betweentheswitchcontactsand

the current rules.

Theearthcable(yellow/green)mustnotbeinterruptedby

The connection cable has to be placed in order that, in

each part, it cannot reach a temperature of 90 °C.

REPLACEMENT OF THE VOLTAGE CABLE

FO 0073

Fig. 5

The connection of the voltage cable to the appliance's

terminal block is of type "Y". This means that its

replacement requires the specific equipment of a

technician.

In this case, only cable type H05V2V2-F T90 must be

used. The cable section must be suitable to the voltage

and the working temperature.

The yellow/green earth wire must be approximately 2

cm. longer than the phase wires (Fig. 5).

To open the terminal block and reach the terminals,

proceed as follows:

l insert the point of a screwdriver into the visible

protrunding part of the terminal block;

l exert a light pressure and lift (Fig. 6)

Should the feeding gas pressure be different or variable

compared with the required pressure, an appropriate

pressure adjuster (for non-LPG) must be fitted on the gas

supply pipe, in compliance with the rules in force.

ADJUSTMENT OF MINIMUM LEVEL

To adjust the minimum level of the burners, proceed as

follows:

• Lighttheburner.

• Turn the knob on the minimum position.

• Removetheknob.
