ELECTRICAL CONNECTION

1) If it is not present, install a disconnector switch
near the equipment with a magneto-thermal
release and a locking differential.
2) Connect the switch disconnector to the terminal
block as given in the wiring diagrams.
3) The selected connection cable must have
characteristics not lower than the H07RN-F with
a temperature of use of at least 80° C and it must
also have a section suitable for the appliance
(see TECHNICAL DATA table).
4) Pass the cable through the hole and tighten the
cable clamp, connect the conductors in their
corresponding position in the terminal board
and fix them. The yellow-green earth conductor
must be longer than the others, so that, in case
of breakage of the cable clamp, it detaches after
EN
the voltage cables
Equipotential bonding
The appliance must be connected to an
equipotential system. The connecting terminal is
positioned near the power cable entry.
It is marked with the following symbol:
Connection to the water mains
Connect the water inlet pipe to the distribution
network, using a mechanical filter and a shut-off
valve.
MOD. N°:
Qn
Before connecting the filter, let a certain amount of V kW: Hz: 50/60 IPX2
water flow out to purge the pipeline of any ferrous
waste.
If the inlet pressure exceeds 300 kPa, install a
pressure reducer.
Drain water
Connect the appliance's drainpipe to the mains.
Before installation
Before installing the appliance, remove the
protective wrapping. Thoroughly clean the work-
surface and the outside of the appliance with
lukewarm water and detergent, using a soft cloth.
Dry with a clean rag.
Start-up
Before starting the appliance, make sure that its
specifications (category and type of gas used)
match those of the family and group of the gas
PUT INTO SERVICE
MOD. N°:
available locally.
Qn
If not, adapt the appliance to the gas family or
V kW: Hz: 50/60
group required (see the paragraph titled "Running
the appliance on other types of gas"). Carry
out the start-up according to the Operating
Instructions.
Testing power rating
Use the nozzles for the rated output on the
appliances.
Capacity can be of two types:
- rated output, as given on the data plate;
- reduced.
Refer to the "BURNERS" table for these nozzles.
The gas supply pressure must be within the ranges
given in the "BURNERS" table.
The appliance will not work outside the specified
pressure thresholds.
If you wish to check the rated output further, you
may do so by using a gas meter according to the
"volumetric method".
However, it is normally enough to simply check
that the nozzles are functioning correctly.
Checking input pressure (Fig. 1)
The input pressure should be measured by using a
gauge (min. resolution 0.1 mbar).
Remove the screw (A) from the pressure socket and
connect the gauge; after measuring, retighten the
screw so that it's absolutely airtight (A).
IMPORTANT: The pressure must be checked with all
gas equipment connected and operating.
Check the power according to the volumetric
method
Using a gas counter and a chronometer, you can
measure the gas consumption in a given unit of
time. This value will be compared to the value of E,
which is calculated as follows:
Burner power
E =
Gas heating power
It's important that the power is measured when the
appliance is in a state of inertia.
Both rated and reduced powers, calculated at the
rated pressure value, are obtained by referring
to the "BURNERS" table. The value of gas heating
power can be requested from the local gas
company.
Checking the operation
Ensure that the type of used nozzles corresponds to
that shown in the "BURNERS" table. Check whether
the pressure reducer has a flow rate greater
than the sum of the consumption flow rate of all
