2.1 TRANSPORT
The oven is generally delivered fastened to wooden pallets (fig. 4).
Each part is protected by a plastic film or by cardboard boxes.
2.2 UNLOADING
NOTE! On receiving the oven, it is advisable to check its conditions
and quality.
Remove the metal seals (fig. 9 item E) if already fitted to the relief
channels (fig. 9 item C).
Raise the equipment using only and exclusively the points indicated at the
pict. 5.
2.3
ENVIRONMENTAL SPECIFICATIONS
To ensure that the oven operates properly, it is advisable to comply with
the following limits:
Working temperature: +41F (+5°C) ÷ +104F (+40°C)
Relative humidity: 15% ÷ 95%
2.4 POSITIONING, ASSEMBLING AND MAINTENANCE
AREAS
WARNING! When positioning, assembling and installing the oven,
the following specifications have to be complied with:
- Laws and standards in force regarding the installation of gas
appliances in large kitchens.
- Laws and standards in force regarding technical regulations for gas
appliances.
- Laws and standards in force regarding technical regulations for
LPG.
- Directives and indications issued by the gas supply network.
- Directives and indications issued by the electricity supply network.
- Local building and fire-prevention laws.
- Accident prevention regulations.
- Regulations in force of the electromechanical rules.
The appliances must be installed in conformity with current
national regulations.
Remove the protective film from the outside of the oven, pulling it gently
to remove all the adhesive.
Should any adhesive remain on the oven, remove using kerosene or
benzene.
The single elements must be placed one on top of the other as specified in
figure 6, placing the feet in the slots of each element below (item A -
fig.6).
Apply aluminium tape for use at high temperatures between the relief
channels of the stacked units; complete the installation with the metal seals
(fig.9 item E) provided, securing them in place with the special screws.
The equipment needs to be placed in a well ventilated area.
The following minimum gaps must be left between the oven and any
combustible or non-combustible construction (see fig. 7):

WARNING! Because the oven is equipped with casters, a restraint
cable assembly must be installed to limit the movement of the
appliance without depending on the connector and the quick
disconnect device or its associated piping. One end of the cable is
anchored to the eyebolt on one of the rear leg extensions, while the
other is anchored to the wall. After connecting the restrain cable,
move the oven to its final location. Then, lock the two front casters.
If disconnection of the restraint is necessary, to reconnect this
restraint after the appliance has been returned to its originally
installed position
For example (fig. 8), after positioning the appliance in location
foreseen and locking the brakes on the front wheels, fix the appliance
to the floor or wall using at least 4 brackets of sufficient strength, so as
to prevent it from moving for any reason; it must be possible to
remove the brackets in order to carry out special cleaning operations.
2.4.1
MOUNTING THE SUPPORT
See Fig.16
Detail A
- bring together the 4 lower pipes,
- insert the legs in the frame and match the holes.
Detail B
- insert all the side pipe screws (short),
- insert only the outermost screws of the front and rear pipes (long),
- insert the nuts on the internal side of the legs,
- tighten well after making sure the assembly is set level and square.
Detail C
- bring the two upper side pipes towards the legs (the hole furthest from
the end goes at the front),
- insert the screws and nuts and tighten them well,
- bring the short upper pipes together, insert all the screws, move the tray
holders together and tighten,
- insert the four lower screws in the short base pipes and tighten.
- move the central tray holders together and tighten,
Detail D
- check that all screws are tightened,
- insert the closing plugs at the ends of the pipes,
- insert plugs into all external pipe holes,
- turn the frame on its side and fix the wheels to the plate; the castor
wheels with brake at the front and the fixed wheels at the back, using
the screws,
- check that all the screws are firmly tightened.
2.5 CONNECTIONS
2.5.1 GAS CONNECTION
CAUTION
DURING PRESSURE TESTING NOTE ONE OF THE
FOLLOWING:
1. The oven and its individual shutoff valve must be disconnected
from the gas supply piping system during any pressure testing of
that system at test pressure in excess of 1/2 PSI (3,45 kPa).
2. The oven must be isolated from the gas supply piping system by
closing its individual manula shutoff valve during any pressure
testing of the gas supply piping system at test pressure equl to or
less than 1/2 PSI (3.45 kPa).
3. If incoming pressure is over 35 mbar (0,5 PSI), a separate
regulator MUST be installed in the line BEFORE the individual
shutoff valve for the oven.
WARNING: To prevent damage to the control valve regulator during
initial turn-on of gas, it is very important to open the manual shutoff
valve very slowly.
After the initial gas turn-on, the manual shutoff valve must remain
open except during pressure testing as outlined in the above steps or
when necessary during service maintenance.
WARNING! Connection to the gas network must only be carried out
by specialised personnel with a proper license.
Check that the appliance has been set up to take the kind of gas that is
actually supplied.
Before connecting to the gas supply, check that the appliance supply
pressure is the one indicated in Tab.1, and that this pressure is
guaranteed to remain unchanged on a long term basis.
If the supply pressure is outside the values indicated, advise the gas
supply company and do not start up the appliance until the cause has
been identified and eliminated.
Connection to the gas network can be fixed or removable, a certified stop
tap must be fitted upstream of the oven.
If flexible pipes are used, they must be made of stainless steel according to
current standards and norms.
Use
LOCTITE 577 sealant on the gas inlet pipe thread.
When connections have been completed, carry out a seal test with the aid
of a non-corrosive leak finder spray.
Certain safety code requirements exist for the installation of gas ovens;
refer to the beginning of Section 2 for a list of the installation standards. In
addition, because the oven is equipped with casters, the gas line
connection shall be made with:
- A connector that complies with the Standard for Connectors for Movable
Gas Appliances, ANSI Z21.69 (in USA), or Connectors for Movable Gas
Appliances, CSA 6.16 (in Canada).
- A quick-disconnect device that complies with the Standard for Quick-
Disconnect Devices for Use With Gas Fuel, ANSI Z21.41 (in USA), or, if
applicable, Quick-Disconnect Devices for Use With Gas Fuel, CSA 6.9 (in
Canada).
2.5.2 VAPOUR AND GAS EXHAUST
WARNING! THE PROPRIETOR IS RESPONSIBLE FOR
PROVIDING AND MAINTAINING AN ADEQUATE
VENTILATION SYSTEM
WARNING! Any accumulation of noxious substances may result in
intoxication or death. It is therefore essential to provide a ventilation
system that is well-designed, properly fitted and regularly cleaned and
maintained in state of constant efficiency throughout the working life
of the appliance. The flow of air feeding the oven and the hood
exhaust flow must be suitably sized.
WARNING! The discharge of exhaust fumes must take place
outwards.
Pizza ovens are equipment that require a ventilation system properly sized
to ensure proper evacuation of combustion gases and vapors.
