4 - INSTALLATION INSTRUCTIONS
4.1 Safety rules
• Only a local gas utility technician is authorized to carry out gas
installations and connections. The statutory regulations (applied
in Germany VDE, Austria ÖVE, Switzerland SEV, etc.) and connec-
tion conditions performed by the gas utility must be strictly
observed.
• Connection to a power balance system for the installation in a
wall is provided for through a connection point. Adhere to cur-
rent local legal requirements for connection.
• Please note the electrical diagram! Compare the wiring diagram
number on the data plate of the appliance with the one shown
on the electrical diagram.
• Do not bend, crush or damage the cables against sharp corners.
• Lay the cables so as to avoid contact with extremely hot surfaces.
• The cable – which is totally sheathed – must be led inside the
appliance through the cable clamp and cable raceway installed
on the appliance.
• Ventilation system installation can be carried only by expert per-
sonnel.
• If the appliance is to be installed near walls, dividing walls,
kitchen equipment or decorative panelling, these should be in
non-inflammable material. If not, all appliances must be coated
with thermal-insulation fireproof material. Make sure that all fire
prevention standards and safety precautions are strictly adhered
to.
4.2 Structure, equipment and safety devices

• The bodies of the burners and the venturi tubes are made of cast
iron, while the lid is brass.
• 18/10 chrome-nickel steel cooking top.
• Knobs in thermosetting material.
4.2.2 Oven
The cooking chamber is made of stainless steel.
The runners for the pans are made of steel or chromed rod iron.
The pull-out grill i sin chromed rod-iron.
The door, with double wall and thermal insulation, is equipped with
an insulated handle and a hinge with balanced spring.
The insulation of the cooking chamber is fibreglass.
Gas version GN 2/1 and MAXI
The tubular burners are in chromed steel and are resistant to ther-
mal and mechanical stress.
Gas is supplied through a safety valve with a thermostat.
The main burner is switched on from a pilot burner with a fixed noz-
zle. It is also supplied with a thermoelectric ignition safety
with thermocouple connected to the pilot burner. The burner has a
piezo ignition.
The adjustment of the oven temperature, which can be varied
between 160 and 300° C, is made with the thermostat.
The bottom of the oven, in cast iron with reinforced ribs (for GN 2/1)
and steel (for MAXI), is in two pieces.
The smoke collector is in aluminised sheet metal and the protection
grill is in enamelled cast iron.
Gas version GN 1/1 ventilated
The tubular burners are in stainless steel and are resistant to ther-
mal and mechanical stress.
Gas is supplied through a safety valve with a thermostat and a safe-
ty thermocouple.
The ignition of the main burner takes place by means of an AT
transformer.
The adjustment of the oven temperature, which can be varied
between 160 and 300° C, is made with the thermostat.
The bottom of the oven is made of stainless steel.
The smoke collector is in aluminised sheet metal and the protection
grill is in enamelled cast iron.
Electric version GN 2/1
The heating elements are in the top (upper heat) and under the
bottom (lower heat).
Temperature adjustment between 50 and 300° C is made by a ther-
mostat connected to a tri-polar switch.
It is possible to turn on the upper and lower heating elements sepa-
rately or at the same time.
Indicator lights show when voltage is supplied to the appliance (see
Fig. 4A).
The cooking chamber is made of stainless steel.
The upper heating elements are visible (grill), while the lower ones
are covered by a sheet of stainless steel.
Electric version GN 1/1 ventilated
The heating elements are in the top (upper heat), under the bottom
(lower heat), and in the rear around the fan (convection).
The upper heating elements are visible (grill), while the lower ones
are covered by stainless steel panels.
Temperature adjustment between 50 and 300° C is made by a ther-
mostat connected to a switch.
The use of a 9-position commutator makes it possible to light the
heating elements separately or at the same time with ventilation or
in static mode.
The lighting of the heating elements is indicated by 2 indicator
lights (see fig. 4B).
4.2.3 Neutral cabinet
In models ADA20007 and ADA20008, a neutral cabinet with a door
alongside the oven is standard.
4.3 Assembly
4.3.1 Installation premises
The appliance should be installed in a well-ventilated room, and if
possible under a range hood (check current regulations).
The appliance can be installed on its own or with other similar
equipment.
If the appliance is to be installed near inflammable walls, a minimum
distance of 150 mm around the sides and back should be allowed.
If this distance cannot be obtained, take proper heat-protection
action such as fitting tiles or thermal radiation protection material
to the walls.
Before connecting the appliance to the gas supply, check on the
data plate that the appliance is suitable and type-tested for the
type of gas available.

5.1 Preparation and Start-up
Before starting up the appliance, remove the protective wrapping.
Then carefully clean the working surface and the external parts with
lukewarm water and detergent, using a damp rag to remove all traces
of anti-rust material applied in the factory, then dry with a clean cloth.
5.1.1 Start-up
Before starting up the appliance, check that its specifications (cate-
gory and type of gas used) match those of the family and group of
the gas available locally.
If not, it is necessary to adapt the appliance to the gas family or
group required (see paragraph “Conversion and adjustment”).
To start up the appliance, see the instructions for regular use.
5.1.2 Check of power
The appliances must be used with the specific nozzles for the nomi-
nal power.
The power may be:
• the nominal power indicated on the data plate of the appliance;
• the reduced capacity power.
These nozzles are shown in table 1 “Technical data”.
Nominal power is also obtained in respect of the supply pressure:
• from 15 to 22.5 mbar for gases of the second family (G20/methane)
• from 25 to 45 mbar for gases of the 3rd family
(G30/propane, G31/butane)
The appliance shall not be operated outside the above-mentioned
pressure ranges.
To adjust power with reduced capacity, use the data in table 1.
If you wish to further check the nominal power, you may do so by
using a gas meter according to the so-called "volumetric method".
A simple inspection is usually enough to check if nozzles are func-
tioning correctly.
5.1.3 Checking the input pressure (Fig. 1)
Input pressure should be measured using a fluid measuring gauge
(e.g. a gooseneck pipe, min. resolution 0.1 mbar).
Remove lock screw (22) from the pressure intake tube and connect the
gauge hose: once measurement is complete, replace the screw (22).

6.7 Appliance care and frequency of maintenance
Attention! When cleaning, carefully avoid washing the
appliance with direct water jets or high-pressure
water!
Cleaning must be performed when the appliance is cold.
Thorough daily cleaning of the appliance, after disconnecting it, will
keep it in perfect working order and make it last longer. All steel
parts should be cleaned with water and a detergent, using a damp
cloth; do not use abrasive substances or corroding detergents.
Do not use steel wool, which could cause rust to form.
For the same reason, avoid touching the appliance with anything
made of iron. Do not clean with sandpaper and lubricating gel paper.
If absolutely necessary, you may use pumice powder.
If the appliance is extremely dirty, use a synthetic sponge (i.e.
Scotchbrite sponge).
After cleaning the appliance, rinse with clean water and wipe with a
clean cloth.
If the main burner needs cleaning, proceed as follows:
• Remove the pan support, cover, rings and burner crown;
• Clean burner parts with water, soap and a suitable tool, then
rinse and wipe;
• When reassembling the parts, make sure you place them back in
the right position.
All maintenance and repair work must be carried out by authorized
technicians only.
Never clean the appliance with water jets or high-pres-
sure water!
The appliance must be checked at least once a year. For this reason,
a service agreement contract is recommended.
6.8 Recommendations for the treatment of
stainless steel industrial kitchens
6.8.1 Useful information on stainless steel
Industrial kitchens are generally made of stainless steel having the
following material codes:
• 1.4016 or 1.4511 = magnetizable chromed steels
• 1.4301, 1.4401 and 1.4571 = non-magnetizable chromed steels
Chromed steels have favourable thermo-technical characteristics. In
fact, they have less of a tendency to warp due to the effect of heat.
Chrome-nickel steels, instead, have good corrosion resistance features.
Stainless steel corrosion resistance is given by an inactive coat that
builds up on the surface by coming into contact with oxygen.
The oxygen in the air is already enough to build up the inactive coat
that allows automatic removal of anomalies and damage due to
mechanical actions. The inactive coat builds up or re-builds up faster
if the steel comes in contact with running water containing oxygen.
A more powerful effect is given by oxidative acids (nitric acid, oxalic
acid). These acids are used if the steel has undergone strong chemi-
cal stresses, hence generally losing its inactive coat.
The inactive layer can be chemically damaged or jeopardized by
reducing agents (oxygen consumption) if they come in contact with
the steel, concentrated or at high temperatures. These active sub-
stances include for instance:
• saline and sulphurous substances
• chlorides (salts)
• concentrated spices such as mustard, vinegar essences, soup
cubes, kitchen salt solutions, etc.
More damage can be caused by:
• outside rust (i.e. from other components, tools or incipient rust)
• iron particles (i.e. file dust)
• contact with non-ferrous metals (element build up)
• lack of oxygen (i.e. no air inlet, water lacking oxygen).
6.8.2 Warnings and advice for maintenance of stain-
less steel appliances
• Stainless steel equipment surfaces must be kept clean and in
contact with air at all times. When not running, keep appliance
doors open so as to allow air to run through it.
• Regularly remove calcium , grease, starch, and egg white
deposits where rust may build up if there is lack of air. Do not
use bleaching products or products containing chloride. Follow
all indications given by the company concerning special soaps
and cleaning methods to be used for the appliance. If no specific
cleaning recommendations are available, it is necessary, however,
to use detergents having a low chloride content.
After cleaning, remove all soap residues with plenty of clean
water and thoroughly dry the surfaces.
• Minimize contact of stainless steel with concentrated acids,
spices, salts, etc. Even acid vapours coming from cleaning the
tiles favour stainless steel corrosion.
• IParticularly for pots and multiple appliances, it is not recom-
mended to load the cooking chamber only with food having a
high salt content.
It is preferable to cook different food together, i.e. fatty dishes
or vegetables containing acids.
• Avoid damaging the stainless steel surface, in particular with dif-
ferent metals. Residues from other metals help build up the for-
mation of chemical microelements that may cause rust. At any
rate, it is appropriate to avoid contact between iron and steel
since it produces rust. Any contact between stainless steel and
iron (steel wool, pipeline chips, chalybeate waters) can start cor-
rosion phenomena.
As for mechanical cleaning, it is recommended to use only steel
wool or natural, plastic or steel bristle brushes. Steel wool or
brushes with stainless steel can cause rust due to rubbing. Newly
formed rust spots can be removed with slightly abrasive liquid
soaps or fine-grained sand paper. Larger rust spots can be
removed with 2-3% of hot oxalic acid solution. If these cleaning
products do not do the job, a nitric acid (10%) treatment is
required.
Attention! These treatments can be carried out only by
expert personnel according to current regulations.
