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.

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.

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.
