HOB BURNERS CONTROL KNOBS  
Carefully supervise cookings with fats or oil,  
since these types of foodstuff can result in a fire,  
if over-heated.  
The hob burners control knobs are situated on the hob  
front panel. The symbols on the knobs mean that :  
there is no gas supply  
there is maximum gas supply  
there is minimum gas supply  
LIGHTING THE BURNERS  
For easier lighting, proceed before putting a pan  
on the pan support.  
Push the relevant knob down and turn it anti-  
clockwise until it reaches the "maximum" position.  
After lighting the flame, 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 .  
FO 0204  
Fig. 1  
Always turn the flame down or put it out before  
taking the pans off the burner.  
USING THE HOB CORRECTLY  
To ensure maximum burner efficiency, it is strongly  
recommended that you use only pots and pans with a  
bottom fitting the size of the burner used, so that flame  
will not spread beyond the bottom of the vessel (see the  
table beside).  
It is also advisable, as soon as a liquid starts boiling, to  
turn down the flame so that it will barely keep the liquid  
simmering.

fat, when it is open. Do not use it for any other  
purpose.  
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.  
FO 2237  
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.  
Carefully wash the stainless steel components with  
water, then wipe them dry with a soft cloth.  
The pan supports are dishwasher proof.  
If the marks are particularly difficult to remove, use  
common non-abrasive cleaners or specific products.  
Never use steel wool pads or acids.  
In models provided with electric ignition, this feature 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.  
PAN SUPPORTS  
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, as shown in fig. 2.  
To take the pan supports completely off the hob,  
proceed as shown in fig. 3.  
FO 2238  
PERIODIC MAINTENANCE  
Fig. 2  
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.  
The periodic lubrication of the taps must be  
carried out by qualified personnel, which you  
must refer to also in case of malfunctioning.

4. Instruction for the Installer  
The side walls of the unit in which the hob is  
going to be installed, must not exceed the height  
of the working top.  
GAS CONNECTION  
It is indispensible that the connection to the gas mains  
are carried out by means of an AGB tap. Choose fixed  
connections or use a flexible pipe in AGB (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  
combinated with an oven.  
Avoid installing the appliance in the proximity of  
inflammable materials (e.g. curtains, tea towels  
etc.).  
Thefollowinginstructionsaboutinstallationand  
maintenance must be carried out by qualified  
personnel in compliance with the regulation in  
force.Theregulationtobeappliedforthistypeof  
installation is NBN D 5I.003 : "Installations  
functioning with combustible gas lighter than  
air".  
This hob can be operated by Slochteren gas (G25) with  
a nominal pressure of 25 mbar or by natural gas with  
nominal pressure of 20 mbar. No regulation is required  
for use by these two types of gas.  
The appliance must be electrically disconnected  
before all interventions. If any electric supply to  
the appliance is required to carry out the work,  
ensure all the necessary precautions are  
followed.  
Before fitting the appliance ensure that the installation  
hasthecorrect voltagefortheappliance.Atfullcapacity,  
the drop in pressure must not exceed 5%. Such a drop  
in pressure is caused by the following parameters:  
-
