4 FINAL OPERATIONS 
After carrying out the above adjustments, remount in reverse order to the 
instructions given in paragraph “3.1 Replacement of nozzles on the hob”. 
  
 
 After having regulated the device with gas other than the one tested, 
replace the label located on the guard with the one that corresponds to 
the new gas. 
The label is available from your nearest Authorised Assistance Centre.   
 
4.1 Regulation of minimum for town gas and natural gas 
Light the burner and set it at minimum position. 
Remove the knob and turn the regulation screw 
inside or next to the gas tap pin (depending on the 
model) until you get a suitable minimum flame. 
Replace the knob and check burner flame stability: 
(when you turn the knob quickly from maximum to 
minimum position, the flame should not go out).  
Repeat this operation for all the gas taps. 
  
 
4.2 Regulation of minimum for LPG 
To regulate the minimum for LPG, fully tighten the screw inside or next to 
the gas tap pin (depending on the model) in a clockwise direction. 
The diameters of the by-passes for each burner are given in table “3.2 
Burner and nozzle characteristics table”. 
 
 
4.3 Lubrication of gas taps 
 With time it may happen that the gas taps get blocked and hard to turn. 
Clean them inside and re-grease them. This operation must be done 
by an authorised person.

5 USING THE  HOB 
 5.1 Ignition of the burners 
  
Before turning on the burners, make sure that the flame-spreader crowns 
and respective caps are properly fitted in their housings. Ensure the 
flame-spreader holes A are aligned with the ignition plugs and the 
thermocouples.
  
To prevent damage to the work top, the hob comes complete with a 
raised pan stand H. This must be placed under pans with a diameter 
bigger than those indicated in the table in paragraph 5.3 Pan 
diameters. In any case, pans with a diameter greater than 28 cm must 
be used solely on the central burner. 
The pan stand Hcan also be used with woks.

  A symbol next to each knob indicates the relative
burner. The device is fitted with electronic ignition.
Simply press and turn the knob counter-clockwise to 
the high flame symbol 
 until the burner is ignited.  
    In models with safety valve, after ignition, the knob has to be held down 
for a few seconds to allow the thermocouple to heat up. The burner 
might go off when the knob is released: this means the thermocouple 
has not heated up sufficiently. 
Wait a few moments and then repeat the operation, holding the knob 
down for longer. This operation is not necessary for burners without 
thermocouples. 
Once the burner is ignited, adjust the flame as required. 
Always check that the control knobs are in the position     (off) when you 
finish using the hob. 
 
If the burners turn off accidentally, a safety device will trip after about 20 
seconds to cut off gas flow (even with the gas tap open).

5.2 Practical advice for using the burners 
 
For better use of the burners and lower gas consumption, use covered 
cooking receptacles that have a flat, smooth bottom and are proportional 
in size to the burner to prevent the flame from licking the sides (see 
paragraph “5.3 Pan diameters”). When water reaches boiling point, lower 
the flame so that it does not boil over.  
 
To avoid burns or damage to the worktop, all receptacles must be placed 
within the perimeter of the cooking hob.  
 
When using fats or oils, be extremely careful that they do not overheat 
and catch fire.

6 CLEANING AND MAINTENANCE 
 
 
Before any intervention, disconnect the appliance from the mains. 
 
 
Never use a steam jet to clean the appliance. 
 
6.1 Cleaning the stainless steel 
 
 To keep stainless steel in good condition it should be cleaned regularly 
after use. Let it cool first. 
6.1.1 Routine daily cleaning 
To clean and preserve the stainless steel surfaces, always use only 
specific products that do not contain abrasives or chlorine-based acids. 
How to use: pour the product on a damp cloth and wipe the surface, rinse 
thoroughly and dry with a soft cloth or chamois leather. 
6.1.2 Food stains or residues 
Under no circumstances must metallic scourers or sharp 
scrapers be used: they will damage the surface.  
Use normal non-abrasive products for steel, and a wooden or 
plastic tool if necessary. 
Rinse thoroughly and dry with a soft cloth or chamois leather. 
 
 
 
6.2 Cleaning of cooking hob  components 
To facilitate cleaning, the pan stand, caps, flame-
spreader crowns and burners are all removable; 
wash with warm water and non-abrasive detergent, 
taking care to remove all stubborn food residues. 
Wait for all parts to be fully dry before remounting. 
Refit the caps on the respective flame-spreader 
crowns, making sure that notches A align with burner 
pins B. 
 
 To work well, the ignition plugs and thermocouples must 
always be very clean. Check them frequently and clean 
them with a wet cloth if necessary. Any dry residue should 
be removed with a toothpick or a needle.

  In models with central pan stand, fit this piece, taking care that its centre is
perfectly aligned with the centre of the burner
