The following operation requires building and/or carpentry work so must  
be carried out by a competent tradesman.  
Installation can be carried out on various materials such as masonry,  
metal, solid wood or plastic laminated wood as long as they are heat  
resistant (T 90°C).  
2.1.1 Attachment to support structure  
Create an opening with the  
dimensions shown in the figure in the  
top surface of the counter, keeping a  
minimum distance of 50 mm from  
the rear border.  
This device is classified "type Y" as  
regards risks against fire and it can  
be set adjacent to walls that are  
higher than the work surface,  
provided that a distance of 145 mm.  
is respected (as shown in the figure)  
to  
prevent  
damage  
due  
to  
overheating.  
Make sure there is a minimum of 750 mm between the hot plate flames  
and any shelf that may be installed directly above them.  
Carefully position the insulation gasket (supplied) on the external  
perimeter of the hole made in the top surface (see figures below) and try  
to make it stick to the entire surface by applying light pressure with your  
hands. Refer to the coordinates shown in the figure, bearing in mind that  
sides A should be adjacent to the hole. Secure the hob to the counter  
with brackets B (supplied). Carefully trim any excess from border C of the

Instructions for the installer  
4. GAS CONNECTION  
Connection to the gas mains may be made with a rigid copper pipe or  
with a flexible pipe and conforming to the provisions defined by standard  
regulations in force.  
To facilitate connection, fitting A on the rear of the appliance may be  
adjusted laterally. For this purpose, loosen hexagon nut B, turn fitting A  
to the desired position, and retighten hexagon nut B (tightness is ensured  
by a biconical brass ring). Use a soapy solution to check for proper  
tightness. Never use a free flame.  
The hob has been inspected for G20 (2H) natural gas at a pressure of  
20 mbar. For use with other types of gases, see Section “5.  
ADAPTATION TO DIFFERENT TYPES OF GAS”. The gas intake fitting  
is ½” gas external threaded (ISO 228-1).  
Connection with rigid copper pipe:  
the connection to the gas mains must  
not provoke stress of any kind on the  
hob.  
Connection may be made by using  
biconical adapter D with insertion of  
gasket C (supplied).  
Connection with flexible pipe: use  
only flexible pipes conforming to  
standard regulations in force, inserting  
gasket C (supplied) between fitting A  
and flexible pipe E.  
The flexible pipe has to be installed so that pipe length does not exceed  
1.5 meters of maximum extension. Make sure that the pipes do not touch  
any moving parts or become damaged.

Instructions for the installer  
4.1 Connection to LPG  
Use a pressure regulator and make the connection to the tank according  
to the provisions of standards regulations in force. Make sure that feed  
pressure conforms to the levels shown in the table in paragraph “5.2  
Regulation for LPG”.  
4.2 Ventilation of rooms  
The hob may be installed only in rooms with permanent ventilation, as  
required by standards regulations in force. The room in which the hob is  
installed must have sufficient air flow to satisfy the requirements of  
normal gas combustion and of necessary air exchange in the room. The  
air intakes, protected by screens, must be appropriately sized  
(regulations in force) and placed so as not to be blocked in any way.  
The room where the oven is installed should be suitably ventilated to  
avoid overheating or excess humidity produced by cooking, and in the  
case of lengthy use a window should be opened or the speed of any  
ventilators should be increased.  
4.3 Discharge of combustion products  
Discharge of combustion products must be guaranteed by means of  
hoods connected to a natural draught flue with certain efficiency, or by  
means of forced aspiration.  
An efficient aspiration system requires careful planning by a specialist  
capable of installing it, respecting the positions and distances prescribed  
by standards. After installation, the installer must issue a certificate of  
conformity.

6. FINAL OPERATIONS  
Having carried out the above adjustments, reassemble the appliance  
following, backwards, the instructions in paragraph “5.1 Removing the  
hob”.  
6.1 Regulation of minimum for natural gas  
Replace the components on the burner and slide  
the knobs on the gas tap pins.  
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: (rapidly turning the knob from maximum  
to minimum position, the flame should not go  
out).  
6.2 Regulation of minimum for LPG  
To regulate the minimum for LPG, completely tighten (clockwise) the  
screw inside or next to the gas tap pin (depending on the model).  
The diameters of the by-passes for each burner are given in table “5.2  
Regulation for LPG”.  
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 inside the bag that contains the nozzles

Instructions for the user  
7. USING THE HOB  
Make sure that the flame-baffle crowns, the caps and the grid have been  
assembled correctly. Grid A (supplied) should be used for "woks"  
(Chinese pots).  
Adapter B (supplied) is to be used for small vessels.  
7.1 Ignition of the burners with safety device  
For each knob the corresponding burner is indicated. The device is fit  
with electronic ignition. Simply press and simultaneously turn the knob  
counter-clockwise on the low point flame symbol, until the burner is  
ignited. Concerning models with valves, push the knob for approximately  
2 seconds in order to keep the flame burning and to activate the safety  
device. The burner might go off when the knob is released. In this case  
repeat the aforesaid operation keeping the knob pressed for more than 2  
seconds.  
Should the burners go off accidentally in the models with valves, a safety  
device will trip after approximately 20 seconds to block the gas outlet  
even if the cock is open.  
7.2 Practical advice for using the burners  
For better burner performance and minimum gas  
consumption, flat bottomed, even recipients must  
be used, with covers and proportional in size to  
the burners (see paragraph “7.3 Diameter of  
containers”).  
To avoid overcooking or damage to the surface  
top while cooking, all recipients or griddles must  
be positioned within the cooking hob perimeter  
and must be a minimum distance of 3-4 cm from  
the knobs.

only, which do not contain abrasive substances or chlorine-based acid  
substances.  
How to use: pour the product on a damp cloth and wipe the surface,  
rinse thoroughly and dry with a soft cloth or deerskin.  
8.1.2 Food stains or residues  
Do not use metallic sponges or sharp scrapers: they will  
damage the surface.  
Use normal non-abrasive products and remove spots or  
residuals with non-scratch sponges or, if need be, with wood or  
plastic utensils.  
Rinse thoroughly and dry with a soft cloth or deerskin.  
8.2 Cleaning of cooking hob components  
Grids, caps, flame cap crowns and burners can be  
removed for ease of cleaning. Wash them in warm  
water using a non-abrasive detergent, taking care  
to remove all tough spots. Before remounting, allow  
the components to fully dry out.  
8.2.1 Ignition plugs and safety devices
