DECLARATION OF COMPLIANCE
The manufacturer declares that the appliances are compliant with the prescriptions of the
EEC norm 90/396 for the gas part and with norm 73/23 for the electric part.
The installation must be done observing the norms in force particularly concerning room
ventilation and discharging gas emissions.
N.B.: The manufacturer declines any responsibility for direct or indirect damage caused by
improper or incorrect installation, maintenance or use of the appliance and alterations, as in
all the other cases considered in the items of our sales conditions.
INSTALLATION
• The operations for installing, conversions for use with other types of gas and starting
up must be done only by qualied personnel whose qualications comply with the
norms in force.
• Gas installations, the electrical connections and the rooms in which the appliances
are installed must comply with the norms in force in the Country in which the instal-
lation is carried out; above all, the appliance must be installed in a well ventilated
room, preferably under an extractor hood, so as to ensure the complete extraction of
gas emissions which are formed during combustion. The air necessary for combu-
stion is 2m3 /h per kW of power installed.
Attention: In accordance with international rules, when connecting the appliance, an au-
tomatic device enabling the disconnection of all contacts from the mains, must be installed
above it; this device must have a contacts opening of at least 3 mm.
CHECKING FOR ADEQUATE VENTILATION
Make sure that the air intake into the room where the appliance is installed is sufcient for an
adequate change of air, as specied by regulations in effect.
The appliances installed in buildings open to the public must satisfy the following requirements.
Installation rules
The installation and maintenance of the appliance must be done according to the correct proce-
dures and regulation
texts in use, particularly:
• safety standards for the prevention of re and panic.
Connection and installation of appliance, ventilation and exhaust removal systems, shall be done
according to the Manufacturer’s instructions and by qualied technicians and according to the
regulations in effect. The electric wiring shall conform to the regulations in effect.
All re prevention codes shall be observed.
a) General indications (Rules valid for GB only)
- For all appliances:
Gas safety Regulations, 1984; Health and safety at Work Act, 1974 Codes of Practice, BS 8173,
1982, The Building

13
Ofcine Gullo
Regulations 1985; The Building Standards Regulations, 1981, the IEE Regulations and the by-
laws of the local Water Undertaking.
The local gas Region or LPG supplier and the local authority and the relevant recommendation
of the British Standards (latest editions) concerned.
The installation, transformation and repair of appliances for professional kitchens as well as re-
moval due to malfunction, and the supply of gas, may be made only by means of a maintenance
contract stipulated with an authorized sales ofce and in observance of technical regulations.
The appliance can be installed by itself or in a series side by side with appliances produced by us.
There must be a minimum distance of at least 10 cm between the appliance and the sides of the
nearby cabinets made of inammable material.
Take suitable measures to guarantee thermal insulation of the inammable sides, such as, for
example, the installation of protection against radiation.
The appliances must be installed in a suitable manner, observing the safety standards.
The small feet are adjustable to level the appliance.
PIPE FOR GAS CONNECTION
The gas connection must be done with steel or copper pipes, or otherwise with exible steel
pipes in compliance with the national norms, if any exist. Each appliance must be provided
with a cut-off cock for rapid interruption of the gas supply. Once the appliance has been
installed, it is necessary to check for gas leaks for the pipe ttings; do not use a ame for
this purpose but a non-corrosive substance such as soapy water or foamy substances as
contained in leaknder sprays. All our appliances undergo careful testing: the type of gas,
the operating pressure and the category are indicated on the data plate.
NB: The year of the appliance manufacture is shown in item “N” on the data plate. The rst
two numbers (e.g. 08..) represent the year of manufacture.
ELECTRIC CONNECTION
The appliance is supplied without the connection cable; to install it, proceed in the fol-
lowing way:
- Remove the back panel
- Push the connection cable through the cable channel, connect the conductor wires to the
corresponding terminals in the junction box and x them into place.
- Block the cable with the cable blocker, and reassemble the panel. The earth wire must be
longer than the others so that if the cable blocker should break, it will disconnect after the
tension wires.
N.B. The connection cable must have the following characteristics: it must be type
H05RN-F and must have an adequate section for the power of the appliance (see tech-
nical data table).

14
Ofcine Gullo
EQUIPOTENTIAL
The appliance must be connected to an equipotential system.
The connection screw is positioned at the back of the appliance and is identied by the
symbol .
Attention! The manufacturer will neither be held responsible for, nor will give any
compensation during the guarantee period for any damage caused, and which is due to
inadequate installations not compliant with the instructions.
CHECKING HEAT OUTPUT
The appliances must be checked in such a way as to verify that the heat output is correct:
• The heat output (thermal power) is indicated on the data plate of the appliance;
• Firstly, check that the appliance can be used with the type of gas supplied; then
check that the indication on the plate corresponds to the gas to be used. For con-
verting to another type of gas, check that the type of gas complies with what is
stated in this instruction manual.
The pressure is read with a gauge (minimum resolution of 0.1 mbar) inserted in the relative
pressure outlet. (gure 1 item C).
Remove the hermetically closed screw and insert the gauge pipe.
After reading, put back the screw tightening it hermetically and check for pressure leaks.
Connection for liquid gas G30/G31
The connection pressure for liquid gas is 30 mbar with butane and 37 mbar with propane.
Check the plate, read the pressure and verify that the description of the nozzle installed
corresponds to the one supplied by the manufacturer.
Connection with natural gas H G20
The connection pressure for natural gas is 20 mbar.
Check the plate, read the pressure and verify that the description of the nozzle installed
corresponds to the one supplied by the manufacturer.
CHECKING PRIMARY AIR TO THE MAIN BURNERS AND PILOT NOZZLES
All the burners are tted with an air regulator by means of which the primary air can be varied
thanks to an adjustable bush that can be locked with a screw. In the “Burner Technical Data”
table you will nd the approximate values for the “h” parameter (primary air). The ow of
primary air must be regulated so there is no detachment of the ame when the burner is cold
or a return of the ame when the burner is hot.
The pilot air is regulated when the appliance is tested and inspected for the gas it is set for.
If you are going to change to a different type of gas, regulate the air by means of the adju-
sting bush until the ame stops sputtering and becomes an intense blue colour.

RULES FOR CONVERTING AND INSTALLING OTHER TYPES OF GAS
Our appliances are tested and regulated for liquid gas (see plate inside).
The conversion or adaptation to another type of gas must be carried out by a specialized
technician. The nozzles for the various types of gas are in a packet supplied with the ap-
pliance and are marked in hundredths of mm (see the technical data table).
CHANGING THE OPEN RING NOZZLES
Main nozzles
Take the rungs off, remove the burners and trays, with a size 12 spanner substitute the nozzles with
the appropriate ones, regulate the primary air (h) (see the “burner” technical data table) unscrewing
the securing screw. Once regulated, tighten the screw, adjust the minimum ame by turning the screw
to the right or left until the thermal power reaches 1,15 kW for the 3,5 kW burner, 1,55 for the 5,5 kW
burner and 2,5 kW for the 7 kW burner.
Warning: If liquid gas is being used the minimum adjustment screw must be locked right down.
SUBSTITUTING THE NOZZLE IN THE OVEN BURNER
To substitute the oven burner, proceed as follows:
• Remove the oven bottom (oor);
• Unscrew the xing screws from the burner nozzle protection.
• Substitute the nozzle, using a suitable spanner (see “burners” technical data table).
• Regulate the air regulation bush to the corresponding value in the “technical data”
table by unscrewing the xing screw with relative jam nut, regulate minimum output
by turning the screw to the right or to the left until the thermal power reaches 2,2 kW
for the burner of 7,3 kW and 3,5 kW for the burner of 11 kW; this procedure is only
possible after having let the oven burner work at maximum output for about 20 minutes
(knob in pos. 300).
• After this procedure, put back the burner nozzle protection.
• Substitute the pilot nozzle, using a suitable spanner.
After regulating, check lighting, at both maximum and minimum output. Make sure
that, when changing rapidly from minimum to maximum output, the ame does not
present any problems and that it doesn’t go out, when closing or opening the oven door
quickly.
Warning: For functioning with liquid gas, screw down the regulating screw completely.
SUBSTITUTING THE NOZZLE IN THE COUP DE FEU BURNER
Remove the panel and with a suitable spanner substitute the nozzle with another, suitable one.
Adjust the minimum ame by turning the by-pass screw either to the right or to the left until
heat output reaches 4 kW.
The primary air of the all plate burner does not need adjusting.
Attention: If liquid gas is used, the minimum ame adjustment screw must be screwed right
down.

CLEANING AND MAINTENANCE
Attention! During cleaning, do not wash the external parts of the appliance with direct
sprays of water or with high pressure.
After every use, clean the appliance thoroughly. Daily cleaning after switching off the ap-
pliance ensures the perfect functioning and long life of the appliance.
Before starting to clean the appliance, disconnect the power supply. The parts in steel must
be washed with hot water and neutral detergent, then rinsed thoroughly in order to eliminate
all traces of detergent; after which, dried with a dry cloth.
Do not use abrasive or corrosive detergents.
The enamelled parts should be washed with soapy water.
After cleaning, turn the elements back correctly.
Important: As well as ordinary cleaning and maintenance, it is advisable to have the instal-
lation checked by an installer at least once a year.
It is therefore suggested to draw up an after-sales assistance contract.
CLEANING BURNISHED BRASS SURFACES
No synthetic protective varnishes have been used to obtain the special burnishing effect
on the burnished brass details in order to avoid spoiling the beauty of the brass with an
articial patina. The antique nish of the surface is the result of natural oxidation that has
simply been accelerated. All the natural antique nish brass surfaces can be cleaned with
any kitchen degreasing detergent, accompanied by the use of an abrasive scouring pad (the
green colored type used for washing dishes). It is recommended that the metal be rubbed,
uniformly applying light pressure, until the desired effect is achieved.
The brass details should then be dried.
Do not use polish as this is suitable for maintaining the gloss but not the antique nish and
could result in an effect that is not compliant with our products. Any spots that may appear
over time on the burnished brass surfaces should be considered as a desirable and particular
characteristic of our craft metal working processes.
CLEANING CHROMIUM-PLATED BRASS SURFACES
No synthetic varnishes have been used to obtain the special polish on the chromium-plated
brass details in order to avoid spoiling the beauty of the chromium plating with an articial
patina. All the chromium-plated surfaces should be cleaned, where necessary, with a soft,
possibly micro-ber cloth, combined with metal polishing products, if required. Do not use
abrasive pads.
