3. INSTALLATION (only for the installer)
3.1 Installation in premises
The installation and the first starting on must be done by qualified personnel, authorised by the manufacturer.
Appliances must be installed in accordance with the national safety standards regarding gas heated appliances.
This gas heated water grill must be installed in a well-ventilated place having permanent ventilation ducts to
guarantee a sufficient exchange of comburent air and to keep the work premise healthy. It is recomended to
install it under an efficient hood that could evacuate burned gases and cooking steams outside of the premise.
The majority of catering kitchens use mechanical ventilation systems to create a comfortable working
environment that promotes health and safety at work and encourages good practice for hygiene and food
safety. These systems are designed to remove the products from the cooking processes and discharge them to
a safe external location, normally through an hood installed over the cooking appliances. Make-up air is
supplied in the form of natural ventilation through air vents, louvres or serving hatches ets. It is important to
recognise that ventilation systems serve several purpose apart from the removal of combustion products.
They:
• Introduce sufficient clean, cool air and remove excess hot air from the cooking area to enable the
occupants to breathe adequately and provide comfortable conditions;
• Prevent incomplete combustion of gas and the consequent production of harmful carbon monoxide;
• Dilute and remove odours, vapours and steam from the cooking process.
According to national Regulations, this gas heated water grill can be installed as an appliance of construction
type:
• For type A appliances, the instructions shall state that these appliances are to be installed with sufficient
ventilation to prevent the occurrence of unacceptable concentrations of substances harmful to health in
the room in which they are installed. Once the equipment has been converted to another type of gas or a
pressure other than those to which it was previously adjusted, the indications of the new adjustment shall
be given instead of the previous indications so as to provide clear identification of the state of the
appliance after modification. Install the appliances only in a suitable ventilated room;
The flow of air required for combustion , install the appliance in a suitably ventilated room in accordance with
the regulation in force
.
3.2 Packing
Make sure packing is intact before remove the appliance. Open cardboard carefully to ensure no metal
stapling, adhesive tape or other packing components litter the environment, as these can prove hazardous.
Remove the protective film from the external walls of the appliance making sure no glue or plastic is stuck on
the surface. If there are residues of glue, remove them using the right solvent.
Make sure the appliance contains all the accessories (cooking grids, handles, etc.).
Check the packaging is marked with the gas available in place.
After removing the packaging, sell off the packing plastics according to laws about recycling. At the end of its
operating life, do not disperse the appliance in open environment but destine it to suitable areas for salvage
materials.

3.3 Positioning
Make sure there is enough space available to place the appliance and that the surface it stands on is stable and
level.
Make sure the appliance is level on the surface available. If necessary, regulate its height accordingly, by
adjusting the legs of the appliance.
Make sure that the volume of air required for combustion isn't obstructed in any way by objects around or
under the appliance and no flammable bottle is placed near it.
It is recommended always keeping a distance of at least 20 cm from the two side walls and rear wall and the
appliance especially if the adjacent walls are not protected with refractory sheets or fire-resistant materials
made (see Fig. 3B on previous page).
3.4 Gas connection to the network
Before connecting the appliance to the gas network make sure that:
• The present gas on the place corresponds to that for which the apparatus is predisposed: In If it is not does
not proceed with the connection. Regulate the appliance for the gas available following instructions under
3.6.
• The fixed part of the gas system is conform to the prescriptions established in the Building Regulations in
force in the Country. In particular, verify that the sections of the gas pipes guarantee a supply that is
sufficient for all of the gas heated appliances installed in the same premise avoiding excessive pressure
drops.
• The gas bottle (if present) is placed correctly and protected in a dry area; verify that the visible gas pipes
can easily be inspected; if pipes have been installed in chases (in floors and walls), make sure that this
work has been done to a professional standard with reference points that make it possible to find the
pipeline.
• The flexible hose does not touch hot surfaces, that it isn't put under stress and traction and doesn't come
into contact with sharp edges or other things that could damage it.
• o gas leakage occurs testing along the whole gas circuit and using leak finder sprays or other non-
corrosive foams (do not use direct flames to look for leaks).
• The burners are manufactured with a way to stand thermal and mechanical stress and are equipped with
fixed nozzles. This is why it is necessary to change the nozzles every time you change the type of gas.
• Data concerning the appliance setting are to be found on the label on the backside of the appliance.
• Connect the machine to the network using metal pipes, either rigid or flexible.
• Verify that the pressure in use is that of exercise for which the appliance has been predisposed. In no case
the inlet supplying pressure must exceed the maximal pressure foreseen by gas setting and category
according to the Country of destination (see table 4 at last page).
• Use the right sealing materials for all connections and check them for leaks.
• It is important for the adjacent walls to the appliance to be protected against the heat. Interpose refractory
sheets or place the appliance at least 20 cm of distance from the side or back walls.
• The connection of the apparatus to the gas network must be effected through a gate valve. This
valve should be closed when the appliance is not in operation.
3.5 Gas pressure and nominal heat input controls
The main inlet pressure is measured, being the appliance on, using a pressure gauge for liquids (for example a
manometer with a minimum resolution of 0,1 mbar). Please proceed as follow:
• Open the frontal panel in way to enter to the ramp of feeding of water grill.
• Unscrew the screw-cap of pressure point (pressure point is positioned along the gas ramp between the
external threaded connection and the gas tap).
• Connect the manometer and measure the inlet pressure (with the appliance in operation).
• If the value is not between the min. and max. values indicated in the table 4 (reporting pressures for every
Country, categories and types of gases), the appliance cannot be put into service definitely and the gas
company must be informed in order to find out the problems of supply pressure.
• After this measure, move the manometer, re-screw the screw-cap, and verify that there are not leaks.

ominal heat input of appliance can be measured using the gas meter instrument of the premise and a
chronometer; you have to measure the exact gas flow per unit of time, which is consumed when the water
grill (being the only gas heating appliance on) is working at maximum power. This measurement should be
compared to the gas consumption data in technical table A. The tolerance of ± 5 % is allowed for this
measure. If you are measuring top deviations, you should carefully check the diameters and the quality of the
installed nozzles and verify the pressure of the gas network.
3.6 Adaptation to a different gas
If current gas setting of the water grill, which can be verified on labels (either in packaging or in the label
fixed on the back of it), does not correspond to gas available in place the gas adaptation must be carried out.
The appliance should only be adapted by a professionally qualified technician. With reference to technical
data of table 3, replace the main nozzles, the pilot nozzles, adjust correctly the primary air of bush and then
adjust the by-pass screws on gas tapes to set the right rate at the reduced heat input.
Spare nozzles are provided with the appliance on its delivery or can be ordered near the seller.
Make sure that the diameter is printed on each nozzle in 1/100ths of a millimetre. Only adapt the appliance
after you have turned the gas off with the on/off valve upstream and let the appliance cool down.
3.6.1 Replacing the main nozzle and adjusting its primar air
For each main burner, consult technical data on table 3, see Fig. 4 and proceed as follows:
• Access to the main burner after removing the cooking grids, the radiant elements, the drawers
and , in case, overturn the appliance to work easily.
• Unscrew and change the main nozzle “ I “ with the one for the new gas type.
• Adjust correctly the distance H of primary air bush “ B “ according to the new gas setting.
• Fix the air bush by the screw “ V “
• Then replace all the components of the water grill in the reverse order.
