1. INSTALLATION
1.1 The installation, the connection & the calibration of the device or the transformation of the
device for another type of gas, must be done only by authorized technicians always according to
the laws & ordinances, which are valid.
1.2 The device must be located in a very well ventilated area, under an air-extractor so that the
absorption of the gases that are generated during it’s function to be fully achieved.
1.3 Remove carefully the plastic coverage from all parts of metallic surface of the device ahead &
rear so as to be clear without plastic residues.
1.4 The attachment of the device with the gas supply must be done with the appropriate metallic
tube without any junctures, or with a special flexible metallic tube according to the laws & the
ordinances, which are valid.
1.5 It is necessary to install a switch (sluice), between the device & the gas supply which must be
closed by the operator when this specific device is not in use.
1.6 After the completion of all the above, check out all the connections to make sure that there is
no leak. For that check, use only a special spray for that purpose.

2. CONTROL & ADJUSTMENT OF PRESSURE
2.1 This device is regulated & controlled in order to function with Natural Gas, with pressure
20/25mbar.
In order to operate this device with a different gas, it is necessary to regulate the device with the
type of gas that is going to be used.
2.2 The pressure that corresponds to different types of gas is shown at Table 1.
28-30/37 mbar for propane - butane (GPL).
20/25 mbar for natural gas
See at Table 1.
2.3 STAGES OF PRESSURE CONTROL (Fig. 1)
In order to control the pressure use a manometer with a division at least 0,1 mbar.
Unscrew the insulate bolt (2) of the pressure control point (1).
Connect the manometer at the pressure point (1).
Check that the pressure of the device is the appropriate for the type of gas you are going to use.
Remove that manometer.
Screw the insulate bolt (2) at the pressure control point (1).
Check for leak !

3. CONVERSION TO DIFFERENT TYPES OF GAS
3.1 In order to achieve main transformation from natural to propane gas you must change the
nozzle of the burner. The size of the nozzle, which corresponds to the type of the gas appears at
Table - 1.
3.2 CHANGING THE MAIN BURNER’S NOZZLE (Fig. 2)
In order to change the nozzle (Νο 2, Fig. 2), unbolt it and bolt the appropriate nozzle. In every
appliance you will find in a socket the appropriate nozzles for natural gas.
ATTENTION !!!
After changing the nozzle make a leak check.

3.3 REGULATION OF THE SMALL FLAME (Fig. 3)
Turn on the main burner according to the instructions, turn the knob at the position MIN of the
little flame (Νο 1, Fig. 3). Make sure that, at the position MIN, burner’s flame is still alight, even
during rapid turning of the knob from the MAX to the MIN.
In case that at the position MIN, burner’s flame dies down, or if the flame is very strong then do
the following steps:
Keep the knob at the position MIN
pull off the knob of the rubinet and with a small screwdriver regulate the screw of the rubinet,
which is located behind the hole (No 2, Fig. 3).
When you turn the bolt right you reduce the intensity of the flame, and when you turn it left
you make the flame stronger.
Regulate the intensity of the flame at your will. Then put back the black knob of the rubinet at
its former position.
Fig. 3: Regulation of the intensity of flame
3.4 FINAL FUNCTION CHECK
Turn the device on following the instructions on the next pages.
Check with a special spray if there is a leak.
Check the intensity of the burner’s flame turning the knob of the rubinet from the little to the
big flame.
Make sure that during the ignition the flame is widespread everywhere in the burner and that
it has a steady deep blue color.

4. OPERATION INSTRUCTIONS
ATTENTION !!!
This device is designed only for professional use & must be used exclusively by experienced &
well-trained personnel.
The device must be constantly supervised during its usage.
4.1 BEFORE TURNING THE DEVICE ON
We would like to advice you to clean thoroughly the GYROS before to begin to use the machine.
See the paragraph “4.8 Instructions for the cleanup of the device”.
4.2 Open up the gas supply.
4.3 IGNITION OF THE BURNER (Fig. 4)
The burners have to be switched on beginning from the bottom to the top and not the other way
round. In order to switch on the first burner press slightly inboard the knob of the rubinet
(No 6, Fig. 4) and turn anticlockwise (left), until the position that is the reading of MAX. At this
position keep well pressed the button while at the same time you are giving fire to the first
burner.
At the first time of the operation of the device you may have to repeat the previous procedure so
as to achieve the vaporization of the air that exists inside the burner.
When the burner ignites keep the button pressed inside for 10 seconds so that the thermocouple to
be heated, so that it keeps the flame of the burner on.
In order to reduce the intensity of the burner’s flame turn the knob of the rubinet at the position
MIN of the little flame.
4.4 TURNING THE BURNER OFF
Always, the burners have to be switched off beginning from the top to the bottom.
The burner would stop functioning when you turn the rubinet’s right (clockwise), until the position
that the fire of the burner stops. By this way you stop the gas supply to the burner.
4.5 PUTTING THE INOX SPIT (Fig. 5)
The device has to be switched off during the time that you place the spit with the meat on the
machine.
You place the spit with the meat inside the bottom support base (Νο 5, Fig. 5) and at the same
time you pull up the top round disk (No 5, Fig. 4) you place the spit in its place and then you
pull down the top round disk.
ATTENTION !!!
Before to operate your machine do a double check that the spit is well inside its position and
none of the top or bottom spit´s supports move.

4.6 DISTANCE REGULATION FROM THE BURNERS
In order to regulate the distance of the burners from the spit you have to pull out the
movement mechanism (No 1 Fig. 4) the main body will move back or in front at the distance
you wish.
You can as well regulate the distance of the spit by unscrewing the top regulator (No 3, Fig.
4) and moving the top disk back (No 4, Fig. 4) or in front to the desired position.
4.7 MOTOR´S FUNCTION
In order to begin motor´s function you have to push the button of the motor (No 2, Fig. 4)
at the position ON.
4.8 INSTRUCTIONS FOR THE CLEANUP OF THE DEVICE (Fig. 5)
In no case should you clean the device with a flow of water or with a potent acid.
The use of acid might inflict rust to the metallic surfaces.
The cleanup must be done only when the device is cold and out of function.
It is necessary to clean the device after each operation.
You can clean the device with a sponge using only special products for stainless surfaces.
Follow the next steps to clean the moveable parts of your appliance (See Fig. 5).
Remove the spit (No 3, Fig. 5).
Remove the burners’ protection net (No 1, Fig. 5).
Remove the spit’s support mechanism (No 4 & 5, Fig. 5).
Pull out the oil collector (No 2, Fig. 5).
Wash and clean the moveable parts of your appliance and after set them back to their positions.
WARNING !!!
Do not direct jets of water, against the appliance to prevent any water entering in the
components. No water with or without pressure should be used underneath the machine where
is the motor and all the electric connections.
4.9 MAINTENANCE
The correct operation of your appliance is guaranteed only if these instructions are followed
carefully.
Any repairs or maintenance operations must be performed only by qualified technicians.
We recommend to have the appliance controlled at least once a year, for this purpose it is
advisable to apply for a service contract.
Keep the thermocouple constantly clean and treat them carefully.
