INSTALLATION
Warning
Installation operations, any conversion to other types of gas and start-up must only be
performed by qualified personnel, in accordance with current regulations.
Gas systems, electrical connections and premises where the appliances are installed must comply with
current regulations in the country of installation; in particular, the appliance must be installed in a room with
good ventilation, if possible under a suction hood to ensure complete evacuation of the exhaust gases
formed during combustion. The air required for combustion is 2 m3/h per kW of installed power. The
appliance can be installed alone or in series with other appliances in our production range. A minimum
distance of 10 cm between appliances must be respected to prevent contact with any walls made of
flammable material; furthermore, appropriate measures should also be adopted to ensure the thermal
insulation of flammable parts, such as the installation of heat shields; take special care to ensure that
appliances are installed in an appropriate and safe manner. The support feet can be adjustable in height and
any unevenness can therefore be eliminated.
ELECTRICAL CONNECTION
Caution
In accordance with international provisions, when connecting the appliance an automatic
device must be installed up-line of it so that the device can be fully disconnected from the
mains; this device must have a contact aperture of at least 3 mm.
The connection terminal is located behind the rear wall. Proceed as follows to install the power supply cable:
· Remove the rear panel.
· Pass the new connection cable through the cable gland, connect the leads to the corresponding terminal
on the terminal block and fasten them securely.
· Lock the cable with the cable gland and refit the panel. The earth/ground lead must be longer than the
others so that if the cable gland breaks it is disconnected after the power cables.
Note
Make sure that the mains voltage complies with the data on the appliance's ID plate and that there is
good conductivity to earth/ground. Pay attention when inserting leads to ensure they do not obstruct
the normal course of work and routine appliance cleaning operations. Also make sure that the power
cable is never pulled taut and is not placed in contact with sources of heat.
Note
The connection cable must have the following characteristics: it must be silicone type (to
withstand temperatures of 180 °C), and must have an appropriate cross-section for the power
of the appliance (see technical data table).
EQUIPOTENTIAL
The appliance must be connected to an equipotential system. The connecting screw is located on the rear of
the appliance and is marked by the yellow symbol above it.
Warning
The manufacturer is not liable for and does not indemnify damages caused by incorrect
inadequate installations that do not comply with these instructions.
GAS CONNECTION
The gas connection (see installation drawing) must be implemented using steel or copper pipes or steel
hoses, in compliance with applicable national standards. All appliances must be equipped with a gas shut-off

INSTALLATION
valve and fast-closing valve. Once installation is complete, make sure that there are no gas leaks from the
fittings; to do this, do not use a naked flame but substances that do not cause corrosion, such as solutions of
soapy water or leak detectors. All our appliances are subjected to detailed examination: the type of gas,
pressure in use and the pertinent category are indicated on the data plate (see attachment).
Note
The year of construction of the appliance is indicated under "N" on the data plate. The first 2 digits
indicate the year of construction.
· THERMAL OUTPUT CONTROL
The appliances must be checked in order to verify that their thermal output is correct:
· Thermal output is indicated on the appliance's data plate;
· Firstly, make sure that appliance is set for the type of gas used and then make sure that the indication on
the data plate matches this gas. To adapt the appliance to another type of gas, make sure that the type of
gas in question complies with the information in this instruction manual.
Warning
Pressure is measured with a pressure gauge (minimum resolution of 0.1 mbar) mounted on
the appropriate socket. Remove the M6 locking screw and insert the pressure gauge tube.
The test must be performed with all the burners on the appliance switched on and all the
appliances in the same line switched on. After taking the measurement, replace the screw,
firmly tighten and check the seal.
Liquid gas connection G30 / G31
The liquid gas connection pressure is 30 mbar for butane and 37 mbar for propane. Check the data plate,
measure the pressure and verify that the description of the nozzle installed matches the information provided
by the manufacturer.
Methane gas connection H G20
The methane gas connection pressure is 20 mbar. Check the data plate, measure the pressure and verify
that the description of the nozzle installed matches the information provided by the manufacturer.
· CHECKING THE PRIMARY AIR FOR MAIN BURNERS AND PILOT NOZZLE
For burners equipped with air adjustment, set the adjustable bushing and lock it with a screw. The "Burner
technical data" table shows approximate values for the "h" parameter (primary air). The primary air flow
volume must be adjusted to avoid a flame cut-off when the burner is cold and a flame blowback when the
burner is hot. The pilot air adjustment is set testing for the gas which the appliance will use. In the event of
conversion to other types of gas, adjust the air using the adjustment bush until the pilot flame is steady and
has an intense blue colour.
Disposition for conversion and installation for other types of gas:
Our appliances are tested and set for liquid gas or natural gas (see attached data plate). Conversion or
adaptation to another type of gas must be performed by a specialist technician. The nozzles for the various
types of gas are contained in a bag included in the supply and are marked in hundredths of mm (see
"Burners" technical data table).

· Voltage 230V 50Hz
6.4 Minimum setting
· After conversion to use another type of gas, or if a flame is too high when the knob is in position (
small flame), adjust the minimum setting by turning the by-pass screw. For operation with LPG, the
by-pass must be completely closed; for operation with natural gas, it must first be closed and then
opened by 1/4 turn
6.5 Spare parts
It is possible to replace parts such as the gas tap, thermocouple, spark plug or the gas pipes simply and
quickly.
To replace such parts, proceed as follows:
· GAS TAP: after disassembling the front panel, unscrew the gas connection screw couplings, remove the
coupling, replace the faulty parts and install the new ones in sequence
· THERMOCOUPLE: unscrew the pilot burner coupling, unscrew the gas tap coupling in the same way
and replace the element
· HEATING ELEMENTS; open the oven door and remove the wires connecting the heating element.
Unscrew the supports that fasten the oven to the enclosure and then replace it
Caution

CLEANING
7 CLEANING
7.1 Routine cleaning
Caution
The use of flammable fluids to clean the appliance is forbidden
To ensure hygiene and the durability of the appliance, perform external cleaning on a regular basis, taking
care not to damage the cables and the electrical connections. Before starting cleaning, disconnect the
appliance from the power supply. Parts in steel can be washed with warm water and a neutral detergent:
Rinse them thoroughly to eliminate all traces of detergent and then dry with a dry cloth. Do not use abrasive
and corrosive detergents. Enamelled parts must be washed with soapy water. For appliances that included
an oven, cleaning it is made easier by removing the support grid. Thorough, daily cleaning prevents faults
and accumulated deposits of fat and/or food. The steels used in the manufacture of professional equipment
are tried and tested materials of the highest quality. Thanks to their characteristics, they are ideal materials
for use with food substances.
Consequently, when using stainless steel appliances, the following suggestions must be observed:
· Stainless steel surfaces must always be kept clean, also ensuring contact with the air. The lack of oxygen
under layers of scale, starch, egg white or other deposits means that surfaces can be affected by
corrosion
· Do not use products containing salt or sulphuric acid to remove scale. Suitable products are available
commercially but a diluted solution of acetic acid can also be used
· To clean STAINLESS STEEL appliances, it is advisable to use detergents specifically formulated for this
material. For "minor cleaning", a mild washing up liquid solution may also be used
· Do not wash the appliance with jets of water under pressure
· Avoid using detergents containing abrasive powders or bleaches of any kind
· Lockable stainless steel appliances, during periods of inactivity, must be left uncovered so that air can
freely access internal metal surfaces
· Stainless steel must not remain in contact for long periods with concentrated acids or with aromatised
concentrates such as salt solutions, mustard, spice mixtures or the like. At certain temperatures and
concentrations, these substances can damage the passive layer. Contact surfaces must therefore be
immediately rinsed with clean water and then dried
· It is inadvisable to use stainless steel pots exclusively to cook foods in salt water (pasta, rice, potatoes,
etc.). From time to time, these pots must also be used to cook foods containing fats or vegetables. This
helps to prevent damage caused by corrosion
· After cooking foods in salt water, rinse the tanks with fresh water since salt water residues from cooking
form layers of highly concentrated saline solution that can cause spotting corrosion
· To prevent so-called secondary corrosion, prolonged contact of stainless steel with ferritic steels should
be avoided
· Any secondary corrosion spots must be eliminated immediately
· Do not use sharp objects that may scratch stainless steel parts and consequently give rise to
deterioration
