Important; Commissioning The Appliance - Bertos G6F2B Mode D'emploi

Gas connection
The G 3/8 or G 1/2" gas off-take on the appliance can
either be permanently fixed or made detachable using a
standard adaptor.
If flexible hose is used, it must be in stainless steel and to
DIN 3383 part 1 or DIN 3384 standard.
After completing connection, check for leaks using a
special leak-detector spray.
Exhaust system
The appliances must be positioned in rooms which
have suitable system for discharging the products of
combustion; such a system must comply with installation
instructions. Our appliances are classified (see Technical
Data Table) as:
- Type "A" gas appliances:
- Not designed for connection to a line for discharge of
the products of combustion.
- These appliances must discharge the products of
combustion into appropriate hoods, or similar devices,
EN
connected to a flue of proven efficiency, or may be
connected directly with an outdoor vent.
- If such an arrangement is not possible, the unit may
be connected to an air exhaust system which leads
directly outdoors, having capacity which corresponds
to requirements. (See Technical Data Table).
Electrical connection
Before connecting the appliance to the mains, check that:
- The mains voltage corresponds to the values on the
rating plate;
- The appliance is properly earthed;
- The cable is suitable for the power input.
In addition a tripping device with a contact cut-off of
at least 3 mm must be placed between the appliance
and the mains socket so that omnipolar disconnection
is possible. Safety contactors, for example, may be used
for this purpose. The omnipolar switch must be near the
appliance and easily accessible.
The power cable must be approved and have a suitable
cross section for the appliance. (See Technical Data Table)
It should be at least the type H07 RN-F.
The ground yellow-green cable must not be
interrupted.
Equipotential
The appliance must be connected to an equipotential
system. The specified terminal is indicated by a label with
the following symbol:

COMMISSIONING THE APPLIANCE

Before commissioning the appliance
Before commissioning the appliance, remove the
MOD. N°:
Qn
protective wrapping. Thoroughly clean the work-surface
V kW: Hz: 50/60 IPX
and the outside of the appliance using lukewarm water
and detergent.
Start-up
Before starting the appliance up, check that its
specifications (category and type of gas used) match
those of the family and group of the gas available locally.
If not, adapt the appliance to the gas family or group
required (see paragraph "Running the appliance on other
types of gas"). Attention: to ensure proper operation of the
TC (triple crown) burners and their covers, they must be
positioned perfectly, see Fig. 1.1
Avoid positions such as those shown in Fig. 1.2
Testing the power rating
Use the nozzles for the nominal capacity on the appliance.
Capacity can be of two types:
- nominal, as given on the data plate;
- reduced.
These nozzles are shown in the Burner Table.
The gas supply pressure must always be within the ranges
shown in the burners table.
The appliance will not work outside the above pressure
thresholds.
If you wish to check the nominal capacity further, you
may do so using a gas meter according to the so-called
"volumetric method".
It is normally enough, however, simply to check that the
nozzles are functioning correctly.
Checking input pressure (Fig. 2)
Input pressure should be measured using a gauge (min.
resolution 0.1 mbar). Remove screw (F) from the pressure
socket and connect the gauge; after measuring, the screw
should be retightened absolutely airtight (F).
IMPORTANT: The pressure must be checked with all gas
equipment connected and operating.
Control of power with volumetric method
Using a gas counter and a stopwatch, you can measure
gas consumption in a given unit of time. This value will
be compared with the value E and is calculated as follows:
Burner power
E =
Gas heating power
The powers of the burner, both nominal and reduced,
calculated at the nominal pressure value, are obtained
by referring to the Burner Table. The value of the heating
power of the gas can be requested from the local gas
company.
