2.4 POSITIONING, ASSEMBLING, INSTALLATION
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 appliance must be installed according to current
national laws.
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 oven must be positioned in a well-ventilated area, at least 50 cm
from the right - left side walls and rear wall.
This distance of 50 cm is essential in order to guarantee access
during maintenance operations. (See Fig. 6).
Take into account that for certain cleaning/maintenance
operations, the distance needs to be greater than stated here and
therefore, consider the possibility to be able to move the oven for
the purpose of carrying out these operations.
WARNING! After positioning the appliance in location foreseen,
fix the appliance to the floor using at least 2 brackets of sufficient
strength
(Fig.2 item 1) , 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. To fix brackets that are
not supplied by the manufacturer, use commercial snap-on
fasteners, of a type suitable for the floor in question, and self-
threading screws which must only be fastened to the rear base of
the oven.

CONNECTIONS
2.5.1 GAS CONNECTION
WARNING! Connection to the gas network must only be carried
out by specialised personnel with a proper license.
Check that the oven is set up for the type of gas supply available.
Before connecting to the gas supply, make sure that the
appliance supply pressure is the one indicated in Tab.1. This
pressure level must be guaranteed stable over a period of time.
If the infeed pressure is not within the values indicated, advise
the gas supply company and do not start up the oven until the
cause has been traced 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 regulations.
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.
2.5.2 VAPOUR EXHAUST CONNECTION
WARNING! The vapour and gas exhaust connection must only
be carried out by qualified personnel.
The housing for the exhaust vapour suction device is on the top part
of the appliance (see Fig. 7 item B).
Fit the suction device (Fig. 7 item C) (which for shipping purposes is
located inside the baking chamber) using the bolts provided with it,
and make electrical connections as indicated in the enclosed wiring
diagram (See Tab. B).
Proceed by inserting the vapour exhaust pipe into the suction device
connector (Fig. 7 item A).
NOTE: connect the vapour exhaust to the outside using a pipe with
minimum diameter 150 mm.
Any extensions must be fitted so that the top pipes slot into the
bottom ones.
Install the suction device cover housing (Fig. 7 item D).
2.5.3 EXHAUST FUME DISCHARGE CONNECTION
WARNING! THE PROPRIETOR IS RESPONSIBLE FOR THE
SUPPLY AND UPKEEP OF AN ADEQUATE VENTILATION
AND EXHAUST GAS DISCHARGE SYSTEM
WARNING! The gas exhaust must only be connected up by
qualified technicians, in compliance with current regulations.
The appliance in question is of type B11BS and requires natural
exhaust through a working chimney with an extractor switch system.
The extractor switch system is delivered with the oven.
WARNING! Combustion fumes must be discharged to the
outside.
For aeration of the area where the oven will be installed, and
discharge of exhaust fumes, see the instructions in 2.4.
WARNING! Any accumulation of noxious substances may result
in intoxication or death. It is therefore essential to provide a
ventilation and exhaust discharge system that is well-designed
according to current installation regulations, properly fitted and
regularly cleaned and maintained in state of constant efficiency
throughout the working life of the appliance.
The exhaust fume discharge pipe is located at the back, in the top
part of the appliance.
- Fit the extractor switch, (Fig.8 item B), (stored inside the baking
chamber during transport) inserting it into the coupling provided
(Fig..8 item C).
- Fix the chimney safety thermostat holder bracket, which is already
positioned on the ceiling of the appliance, to the extractor switch
using the screws provided (Fig.8 item D).
- Using a

150 mm steel pipe, of the kind commercially available,
make the connection to the extractor switch (Fig.8 item A) in
compliance with current exhaust fume discharge requirements.
- When the oven is fitted to a flue this must be done by means of a
straight vertical section not less than 0.5 metres in length, as
indicated (See Fig.9), combustion fumes are picked up at point
E in
the figure, the pipe F must have a minimum slope of 3% and a
maximum length of 2.5 metres, and it must be connected as indicated
in figure 9.
WARNING! Appliance of type B11bs, the chimney extractor
safety thermostat will trigger if combustion fumes are liable to
return into the room. Before resetting, check and eliminate the
cause of the problem, by inspecting all the ducts channelling
fumes from the appliance to the exterior. Once this has been
done, the appliance can be restored to normal service. To restore
the thermostat to normal operation, first carry out the operations
described under point 6.1 and remove the plastic guard, then
press the thermostat button (Fig.10 Ref. X). This device must
never be disabled. If combustion fumes are returned to the
environment they can cause chronic or acute intoxication, which
may be life-threatening.
If the thermostat has to be replaced, always
ensure that original spare parts are used.
The device blocks the supply of gas to the burner in the event of any
problem in the evacuation of combustion fumes. Please see point 4
on how to start the supply again; it is recommended that you contact
a specialist technician if the device is triggered repeatedly.
In the event of repeated triggering of the device, check that the fumes
are being evacuated properly through the flue.
2.5.4 ELECTRICAL CONNECTION
WARNING! Electrical connection must only be carried out by
specialised personnel, in compliance with current local state
Electric Quality Assurance Corporation requirements.
- Before starting the connection procedure, check that the
earthing system is provided in accordance with European EN
standards.
- Before starting the connection procedure, check that the main
power switch has been turned to the “off” position.
- The rating plate contains all the information necessary for
proper connection.
- Fit a main quadripole switch with fuses or an automatic switch
suitable for the values shown on the rating plate, to allow the oven to
be disconnected from the mains.
NOTE : The device selected should be in the immediate vicinity of
the oven and within easy access.
- The oven is delivered with the required voltage indicated on the
rating plate (See Fig.2).
- To carry out electrical connection, remove the protective cover
located on the rear side of the oven (Fig.10 item A). The connection
cable must be supplied by the installer.
