four legs.
Gas connection
The Gc 3/4" 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 "A1" 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,
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

Connect the unit to the mains, following the provided
instructions (see Fig. 1(:
1( Install, if not present, a disconnecting switch (A( close
to the appliance with a thermal magnetic release and
differential locking.
2( Open the doors (B(, if present, and loosen the screws (C(
to disassemble the control panel (D(.
3( Connect the disconnecting switch (A( to the terminal
board (H( as shown in the figure and in the electrical
diagrams at the end of this manual. The chosen
connection cable must have features similar to the
H07RN-F type cable with an operating temperature of
at least 80 °C and have a section suitable to the unit (see
the TECHNICAL DATA table(.
4( Pass the cable through the passage and tighten
the cable stopper, connect the conductors in their
corresponding position to the terminal board and
attach them. The yellow-green ground conductor must
be longer than the others so that, in the event that
the cable stopper breaks, it disconnects itself after the
voltage cables.
5( If the power supply cord is damaged, replace it with
a special cable of H05RNF or H07RNF type: to prevent
any risk, have the cord replaced by the manufacturer or
their Technical Assistance or by a qualified person
Equipotential
The appliance must be connected to an equipotential
system.
The relative terminal can be found at the rear of the
appliance near the cable inlet, marked by a label.

COMMISSIONING THE APPLIANCE

Before commissioning the appliance
Before commissioning the appliance, remove the
MOD. N°:
protective wrapping. Thoroughly clean the work-surface
Qn
V kW: Hz: 50/60 IPX2
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"(.
Testing power rating
Use the nozzles for rated output on the appliances.
Capacity can be of two types:
- rated output, as given on the data plate;
- reduced.
These nozzles are shown in the table "BURNERS".
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 rated output further, you may
do so by using a gas meter according to the so-called
"volumetric method".
However, it is normally enough to simply 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 consumtpion 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 nd reduced,
calculated at the nominal pressure value, are obtained by
referring to table 1. The value of the heating power of the
gas can be requested from the local gas company.
Check of operation
Ensure that the type of nozzles used corresponds to
