How To Use Your Appliance
The position of the corresponding gas burner or electric hot plate (if present) is indicated on each control knob.
Gas Burners
The burners differ in size and power. Choose the most appropriate one for the diameter of the cookware being used.
The burner can be regulated with the corresponding control knob by using one of the following settings:
- Off

High
Low
To turn on one of the burners, place a lighted match or lighter near the burner, press the knob all the way in and turn in the counter-clockwise direction to the "High" setting.
On those models fitted with a safety device (F), the knob must be pressed in for about 6 seconds until the device that keeps the flame lighted warms up.
On those models fitted with an ignitor (D), the "E" ignition button, identified by the symbol, must first be pressed and then the corresponding knob pushed all the way in and turned in the counter-clockwise direction to
the "High" setting.
Caution: If the burner accidentally goes out, turn off the gas with the control knob and try to light it again after waiting at least 1 minute.
To turn off a burner, turn the knob in the clockwise direction until it stops (it should be on the “•” setting).
Electric Hot Plates (only on certain models)
The hot plates vary in diameter and power: "normal" and "fast". The latter can be identified by a red boss in the center of the hot plate itself.
The hot plate can be regulated by turning the corresponding knob in the clockwise or counter-clockwise direction to any one of the 6 different settings:
0 Off
1 Low
2-5 Medium
6 High
The section entitled, "Practical Cooking Advise", provides information on the recommended settings for various types of food or cooking processes.
When the knob is on any of the settings other than "Off", the "H" operating light comes on.
How to Keep Your Cooktop in Shape
Before cleaning or performing maintenance on your appliance, disconnect it from the electrical power supply. To extend the life of the cooktop, it is absolutely indispensable that it be cleaned carefully and thoroughly on a frequent basis, keeping in mind the following:
- Do not use steam equipment to clean the appliance.
- The enameled parts and the glass top, if present, must be washed with warm water without using abrasive powders or corrosive substances which could ruin them;
- The removable parts of the burners should be washed frequently with warm water and soap, making sure to remove caked-on substances;
- On cooktops with automatic ignition, the end of the electronic ignition device must be cleaned carefully and frequently, making sure that the gas holes are not
clogged;
- The electric hobs should be cleaned using a damp cloth and then rubbed with oil while still warm;
- Stainless steel can be stained if it remains in contact with highly calcareous water or aggressive detergents (containing phosphorous) for an extended period of time. It is recommended that these parts be rinsed thoroughly with water and then dried well. It is also a good idea to clean up any spills.
Gas tap maintenance
The taps may jam in time or they may become difficult to turn. If so, the tap itself must be replaced.
N.B.: This operation must be performed by a technician authorised by the manufacturer.
Practical Advice
Practical Advise on Using the Burners
For best performance, follow these general guidelines:
- Use the appropriate cookware for each burner (see table) in order to prevent the flame from reaching the sides of the pot or pan;
- Alwasy use cookware with a flat bottom and keep the lid on;
- When the contents come to a boil, turn the knob to "Low".
| Burner ø Cookware Diameter (cm) | |
| Fast (R) 24 - 26 | |
| Semi Fast (S) 16 - 20 | |
| Auxiliary (A) 10 - 14 | |
| Triple Crown (TC) 24 - 26 | |
Practical Advice on Using the Electric Hot Plates
In order to avoid heat loss and damage to the hot plate, use cookware with a flat bottom the diameter of which is not less than that of the hot plate.
| Setting | Normal or Fast Plate |
| 0 | Off |
| 1 | Cooking vegetables, fish |
| 2 | Cooking potatoes (using steam) soups, chickpeas, beans. |
| 3 | Continuing the cooking of large quantities of food, minestrone |
| 4 | For roasting (average) |
| 5 | For roasting (above average) |
| 6 | For browning and reaching a boil in a short time. |
Before using the hot plates for the first time, you should heat them at maximum temperature for approximately 4 minutes, without any pans. During this initial stage, their protective coating hardens and reaches its maximum resistance.

Installation Instructions for built-in
The following instructions are intended for the installer so that the installation and maintenance procedures may be followed in the most professional and expert manner possible. Important: Disconnect the appliance from the electrical supply before performing any maintenance or regulation upkeep work.
Positioning the Cooktop
Important: this unit may be installed and used only in permanently ventilated rooms in accordance with British Standard Codes Of Practice: B.S. 6172 / B.S. 5440, Par. 2 and B.S. 6891 Current Editions. The following requirements must be observed:
a) The room must be fitted with a ventilation system which vents smoke and gases from combustion to the outside. This must be done by means of a hood or electric ventilator that turns on automatically each time the hood is operated.

b) The room must also allow for the influx of the air needed for proper combustion. The flow of air for combustion purposes must not be less than 2 m^3/h per kW of installed capacity. The supply of said air can be effected by means of direct influx from the outside through a duct with a inner cross section of at least 100 cm^2 which must not be able to be accidentally blocked. Those appliances which are not fitted with a safety device to prevent the flame from accidentally going out must have a ventilation opening twice the size otherwise required, i.e. a minimum of 200 cm^2 (Fig. A). Otherwise, the room can be vented indirectly through adjacent rooms fitted with ventilation ducts to the outside as described above, as long as the adjacent rooms are not shared areas, bedrooms or present the risk of fire (Fig. B).

Fig. A Fig. B
c) Intensive and prolonged use of the appliance may necessitate supplemental ventilation, e.g. opening a window or increasing the power of the air intake system (if present).
d) Liquidified petroleum gases are heavier than air and, as a result, settle downwards. Rooms in which LPG tanks are installed must be fitted with ventilation openings to the outside in order to allow the gas to escape in the event of a leak. Therefore, LPG tanks, whether empty or partially full, must not be installed or stored in rooms or spaces below ground level (cellars, ect.). It is also a good idea to keep only the tank currently being used in the room, making sure that it is not near sources of heat (ovens, fireplaces, stoves, etc.) that could raise the internal temperature of the tank above 50°C.
Installation of Built-in Cooktops
The gas cooktops are equipped with type X degree protection against overheating. Therefore, the appliance can be installed next to cabinets, provided the height of the cabinet does not exceed that of the hob. For proper installation of the cooktop, the following guidelines must be followed:
a) If the cabinet(s) located next to the cooktop are higher than the cooktop itself, the cabinet(s) must be installed at least 600 mm from the edge cooktop;
b) Hoods must be installed in accordance with the instructions contained in the installation manual for the hoods themselves, and no less than 650 mm from the cooktop;
c) The cabinets installed next to the hood must be located at a height of at least 420 mm from the top, (as shown in Fig. C).

Gas Connection for Cooktop
The cooktop should be connected to the gas supply by an authorized installer. During installation of this product it is essential to fit an approved gas tap to isolate the supply from the appliance for the convenience of any subsequent removal or servicing. Connection of the appliance to the gas mains or liquid gas tanks must be carried out according to the safety standards currently in force, and only after it is ascertained that it is suitable for the type of gas to be used. If not, follow the instructions indicated in the section entitled, "Adapting the Cooktop for Different Types of Gas". If the cooktop is to be connected to tanks containing liquid gas, use pressure regulators that comply with current safety standards.
Important: To insure that the appliance operates safety, the gas is regulated correctly and your appliance lasts over time, make sure that gas pressure levels comply with the indications given in Table 1, "Nozzle and Burner Specifications".
Gas Connection to Non-flexible Pipe
(copper or steel)
Connection to the gas source must be done in such a way as to not create any stress points at any part of the appliance.
The appliance is fitted with an adjustable, "L" shaped connector and a gasket for the attachment to the gas supply. Should this connector have to be turned, the gasket
must be replaced (supplied with the appliance).
The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe.
Gas Connection to Flexible Steel Pipe
The gas feed connector to the appliance is a threaded, male 1/2" connector for round gas pipe. Only use pipes, tubes and gaskets that comply with current safety codes. The maximum length of the flexible pipes must not exceed 2000 mm. Once the connection has been made, ensure that the flexible metal tube does not touch any moving parts and is not crushed.
Check the Seal
Once the appliance has been installed, make sure all the connections are properly sealed, using a soapy water solution. Never use a flame.
Electrical Connection
The cooktops fitted with a tripolar electrical supply cord are designed to be used with alternating current according to the indications on the rating plate located under the cooktop. The earthing wire can be identified by its yellow-green colour.
In the case of installation over a built-in electric oven, the electrical connections for the cooktop and oven should be independent, not only for safety purposes, but also to facilitate removal of one or both in the future.
Electrical Connection for Gas Cooktop
Fit the supply cord with a standard plug for the demand rate indicated on the rating plate or connect it directly to the electrical mains. In the latter case, a single pole switch must be placed between the appliance and the mains, with a minimum opening between the contacts of 3 mm in compliance with current safety codes (the earthing wire must not be interrupted by the switch). The power supply cord must be positioned so that it does not reach a temperature in excess of 50°C above room temperature at any point.
Before making the actual connection, make sure that:
- The fuse and electrical system can withstand the load required by the appliance;
- That the electrical supply system is equipped with an efficient earth hook-up according to the norms and regulations prescribed by law;
- That the plug or switch is easily accessible.
Important: the wires in the mains lead are coloured in accordance with the following code:
Green & Yellow - Earth
Blue - Neutral
Brown - Live
As the colours of the wires in the mains lead may not correspond with the coloured markings identifying the terminals in your plug, proceed as follows:
Connect the Green & Yellow wire to the terminal marked
“E” or ± or coloured Green or Green & Yellow.
Connect the Brown wire to the terminal marked "L" or coloured Red.
Connect the Blue wire to the terminal marked "N" or coloured Black.
Adapting the Cooktop for Different Types of Gas
To adapt the cooktop to a different type of gas than that for which it was designed, (see the sticker under the hob or on the packaging), the burner nozzles must be changed, as follows:
- Remove the pan supports and slide the burners out of the cooktop.
- Unscrew the nozzles using a 7mm socket wrench and replace them with those for the new type of gas. (See table 1, "Burner and Nozzle Specifications").
- Reassemble the parts following the instructions in reverse order.
- On completing the operation, replace the old rating label with the one showing the new type of gas; the sticker is available from our Service Centres.
If the gas pressure is different than that prescribed, a pressure regulator must be installed at the source, in compliance with national standards governing the use of piped gas regulators.
Regulation of Air Supply to the Burner
The burners do not need a primary air regulator.
Minimum Regulation
- Turn the gas valve to minimum.
- Remove the knob and turn the regulator screw (positioned either on the side of the top or inside the shaft) clockwise until the flame becomes small but regular.

natural_image
Two mechanical components with cylindrical pins and mounting base, shown from different angles (no text or symbols)N.B.: In the case of liquid gas, the regulation screw must be fully screwed in (clockwise).
- Make sure that, when the knob is turned rapidly high to low, the flame does not go out.
- In the event of a malfunction on appliances with the security device (thermocouple) when the gas supply is set at minimum, increase the minimum supply levels using the regulator screw.
Once the adjustment has been made, apply sealing wax, or a suitable substitute, to the old seals on the by-pass.
