1 INSTALLATION
1.1 POSITIONING
The appliances have been designed for installation in
closed premises, they cannot be used in the open air
and cannot be exposed to rain.
The place of installation of the oven must have a solid,
at and horizontal surface able to safely support both
the mass weight of the appliance/support and that of
maximum load capacity.
The appliance must be placed in adequately ventilated
premises.
The oven must only be installed on a stable support. The appliance must be removed from its
packaging, its integrity checked and arranged in the place of use, being careful not to position it
above or against walls, sides, partition walls, kitchen cabinets or covers in ammable material.
We recommend scrupulously complying with the reproof Standard in force.
There must be a minimum distance of 2” on all sides
between the oven and the walls or other equipment.
We recommend leaving 20” of space between the left
side of the oven and the corresponding room wall, for
easy oven installation and its subsequent maintenance.
All materials used for packaging are compatible with
the environment; they must be safely kept and disposed of according to the Standard in force.
The oven must be levelled: to regulate the height of
the adjustable feet act, using as reference a spirit le-
vel. Signicant unevenness or inclinations can negatively inuence the functioning of the oven. Slowly remove all protective lm from the appliance
external panels, being careful not to leave traces of adhesive. Check that the heat disposal or
inlet slots and openings are not obstructed.
1.2
WATER CONNECTION
The water pressure must be max. 6 bar. Should the wa-
ter pressure from the mains be higher than such value,
install a pressure reducer upstream of the oven. The
minimum water temperature for the correct functioning
of the oven must be higher than 0.5 bar. The oven has a
softened water inlet. Always install a water softener to
bring the hardness of the water at appliance inlet within
the values of between 5 TH and 10 TH. If the oven is
equipped with automatic washing system and the water
hardness is greater then 10 TH it racommanded to use
softened water for the second water inlet. Connect the
TECHNICAL TRAINING COURSE
"Water" duct to the specic cold water mains, and interpose a shut-off cock and lter. Before
connecting, let sufcient amount of water ow to clean the duct from any iron residues.
Ensure the shut-off cock is located in a place and in a manner to be easily activated at any
momentby the operator.
Attention: in case of water drain pipe fault, it must be replaced with a new one and the old and
faultyone must never be re-used.

1.3
1.4.1
The electric system, as prescribed and specied by the Standard in force, must be equipped
Have professionally qualied staff check that the plug cables section is adequate to the power
absorbed by the appliance.
Loosen the screws xing the left side of the oven and extract it.
Place the power supply cable inside the cable gland hole in the lower part, on the left of the
oven.Connect the cable to the terminal board following the indications on “tab 1”.
Lock the cable with the cable gland.

tab 1
DRAIN CONNECTION
The oven is equipped with a water draining device;such
device is located at the bottom in the rear part of the
appliance and has a tube with a 2” diameter.
Connect the tube that protrudes from the draining device .The draining device is a siphon; we recommend
connecting the tube on an open funnel.
Check that the internal siphon is full of water and, if
not, ll it by introducing water through the drain in the
cooking compartment.
ELECTRIC CONNECTION
with an efcient ground. It is possible to guarantee the
electric safety of the appliance only in the presence of
Standard electric system.
For direct connection to the mains it is necessary to interpose a device between the equipment and the same
mains, dimensioned depending on the load, that ensures
its disconnection and which contacts have an opening
distance enabling the full disconnection, in compliance
with the installation regulations; this device also must be
located in a place and in a manner to be easily accessible
at any moment by the operator.
Bring the main switch, to which the power supply cable
plug will be collected, in position 0 (zero).
The power supply voltage with machine
funcioning,must not be different from the nominal
voltage value of ±10%.

TECHNICAL TRAINING COURSE
1.4.2
When a high current ows through a conductor, differences in potential appear between the
conductor and nearby metallic surfaces near the appliance. As a result, sparks may be produ-
ced between the appliance and surrounding metal surfaces. These sparks could cause serious
injury, damage, or re.
BKI provides an Equipotential ground terminal for the connection of a bonding conductor after
the installation of the appliance per lEC60417-1. This terminal is located on the inside of the
Power Entry Supply box near the Earth connection and is marked with this symbol:
For gas ovens, complete gas connection to the appliance before assembling
the oven side again; for electric ovens assemble the oven side.
1.5
The oven is originally calibrated for functioning with the gas type specied during ordering.
The type of gas for which the oven is adjusted is reported on the technical place on the appliance
During testing, ascertain the factory calibrations carried out on the burners are appropriate for
the specic installation type, by means of analysis of the gases produced by combustion (CO2
and CO) and check of the thermal capacity.
Specically, with oven functioning at full capacity, the values of the undiluted CO present during
draining, must be within 300 ppm (normally a well calibrated pre-mix system does not produce
CO which mean the value should be 0).
If the presence of undiluted CO over such limit is detected, the adjustment of the burners must
be checked by a technician authorised by the manufacturer, who will make all due amendments
ELECTRIC CONNECTION
GAS CONNECTION (GAS OVENS ONLY)
to the devices governing combustion and to the relative parameters. The detected data must be
recorded and become integrating part of the technical documentation of that appliance.
Installation prescriptions
The oven installation and commissioning operations must be
carried out only by qualied staff according to regulations and
standards in force.
The gas systems, the electric connections and the installation
premises of the appliances must be compliant with regulations
and Standards in force.
Bear in mind that the air necessary for combustion of the burners
is of 2 m3/h per kW of installed power.
In activities open to the public, the Standards for the safety
prevention of accidents and re and panic must be complied with.
The connection to the gas supply tting can be carried out using
exible metal piping, interposing an approved shut-off cock in an
easily accessible point.
Ensure that the exible metal connection tube to the gas inlet
tting does not touch overheated parts of the oven and that it is
not submitted to torsion or extension stresses.
Use securing clips compliant with installation Standards.
TECHNICAL TRAINING COURSE
Checks to be carried out before installation
On the technical plate located on the left side of the
oven check that the appliance has been tested for
the type of gas available with the user.
Check the data on the technical plate that the pressure reducer capacity is sufcient for powering
the equipment.
Avoid interposing section reductions between the reducer and the appliance.
We recommend mounting a gas lter upstream of the pressure regulator to guarantee optimal
oven functioning.
Connect the oven to the gas supply system by means of special 1/2” NPG tube.
After gas connection, check there are no leaks on the joints and ttings. For this purpose, use
soapy water or a specic foamy product to detect leaks.
It is opportune for the routine maintenance of the gas ovens to be carried out yearly, in
compliance with specic Standards, by an authorised technician; during which the fuel gas will
be analysed and the thermal power checked.

a) the extracted volume must be above that of the generated fuel gas (see Standard in force);
b) the material with which the hood lter is made must resist the fuel gas temperature that, at
conveyor outlet, can reach 572°F;
FUMES EXHAUST
In compliance with installation Standards, the ovens
must be started in premises suitable for evacuation of
the combustion products.
It is possible to connect the ue passage by means
of a forced evacuation system, like a hood equipped
with mechanical extractor fan. In this case, the gas
supply to the appliance must be directly controlled by
such system and must interrupt should capacity drop
below the prescribed values. When the appliance is
installed underneath the extractor hood, check that
the following indications are complied with:
c) the end of the evacuation duct of the appliance must be positioned inside the projection of
the hood base perimeter;
d) the re-admission of the gas to the appliance must only be possible manually.

A correct adjustment of the coupling between trolley and oven allows to prevent steam or water
leakage, when the trolley is inserted inside the oven with the door closed.
1. The oven must be levelled to allow the edge of the sheet metal seal of the trolley to remain
about 3 mm under the glass limit of the oven door.
2. Then screw spacers must be adjusted between the front and the stop of the trolley, at
13 - 15 mm height.

Before commissioning the oven, scrupulously carry out the necessary checks to ensure the
compliance of the systems and installation of the appliance with the legal Standards and
technical and safety indications in the user manual.
The following points must also be satised:
• The ambient temperature of the place of installation of the oven must be higher than 4°F.
• The cooking compartment must be empty.
• All packaging must be fully removed, including the protective lm applied on the oven walls.
• The air vents and louvers must be open and not obstructed.
• The eventually dismantled oven pieces must be, for installation purposes, re-mounted.
• The main electric switch must be closed and the water and gas shut-off cocks upstream of
the appliance must be open.
