IMPORTANT
When carrying out commissioning of the boiler, you are highly recommended to perform the following checks:
Make sure that there are no liquids or inflammable materials in the immediate vicinity of the boiler.
Make sure that the electrical connections have been made correctly and that the earth wire is connected to a
good earthing system.
Open the gas tap and check the soundness of the connections, including that of the burner.
Make sure that the boiler is set for operation for the type of gas supplied.
Check that the flue pipe for the outlet of the products of the combustion is unobstructed and has been properly
installed.
Make sure that any shutoff valves are open.
Make sure that the system is charged with water and is thoroughly vented.
Check that the circulating pump is not locked (CAUTION: Remember to release the pump coupled with the control
panel, if necessary, to protect the electronic control card).
Purge the system, bleeding off the air present in the gas pipe by operating the pressure relief valve on the gas
valve inlet.
Check that the syphened drip is fully filled with water. If necessary, fill it via the special opening.

The boiler must be installed in a fixed loca-
tion and only by specialized and qualified
firms in compliance with all instructions
contained in this manual.
Furthermore, the installation must be in
accordance with current standards and
regulations.
2.1 BOILER ROOM
The boilers can be installed in any domestic
environment without any location restric-
tions or comburent air requirements.
2.3 BOILER SUPPORT BRACKET
For the mounting of the support bracket of
the boiler, which is supplied, observe the fol-
lowing instructions (fig. 4):
Fix the bracket to the wall with appro-
priate dowels.
Check with a spirit level that it is perfec-
tly in horizontal plane.
2.3.1 Installation plate (optional)
The installation plate code 8081216 is sup-
plied with an instruction sheet for the fixing.
2.3.2 System connection nions
The following optional accessories are avail-
able to facilitate water and gas connection
of the boiler with the heating system:
curve kit, code 8075423
cock kit, code 8091809
Detailed instructions for assembly of the
unions are provided with the kits.
2.3.3 Flow reg lator
At the inlet of the hot water a flow regula-
tor brown is installed, from 12 l/ min (fig.
5).
2.4 CONNECTING UP SYSTEM
To protect the heat system from damaging
corrosion, incrustation or deposits, after
installation it is extremely important to
clean the system using suitable products
such as, for example, Sentinel X300 or
X400.
Complete instructions are provided with
the products but, for further information,
you may directly contact GE Betz.
For long-term protection agains corrosion
and deposits, the use of inhibitors such as
Sentinel X100 is recommended after clea-
ning the system.
It is important to check the concentration
of the inhibitor after each system modifica-
tion and during maintenance following the
manufacturer’s instructions (specific tests
are available at your dealer).
The safety valve drain must be connected
to a collection funnel to collect any dischar-
ge during interventions.
If the heating
system is on a higher floor than the boiler,
install the on/off taps supplied in kit code
8091809 on the heating system
delivery/return pipes.
WARNING:
Fail re to clean the heat system or add
an adeq ate inhibitor invalidates the devi-
ce’s warranty.
Gas connections must be made in accor-
dance with current standards and regula-
tions. When dimensioning gas pipes from
the meter to the module, both capacity
volume (consumption) in m3/h and gas
density must be taken into account.
The sections of the piping making up the
system must be such as to guarantee a
supply of gas sufficient to cover the maxi-
mum demand, limiting pressure loss
between the gas meter and any apparatus
being used to not greater than:
1.0 mbar for family II gases (natural gas);
2.0 mbar for family III gases (butane or
propane).
An adhesive data plate is sticked inside the
front panel; it contains all the technical data
identifying the boiler and the type of gas for
which the boiler is arranged.
2.4.1 Connection of condensation
water trap
The drip board and its water trap must be
connected to a civil drain through a pipe
with a slope of at least 5 mm per metre to
ensure drainage of condensation water.
The plastic pipes normally sed for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the b ilding’s sewer pipes.
2.4.2 Filter on the gas pipe
The gas valve is supplied ex factory with an
inlet filter, which, however, is not adequate to
entrap all the impurities in the gas or in gas
main pipes. To prevent malfunctioning of the
valve, or in certain cases even to cut out the
safety device with which the valve is equip-
ped, install an adequate filter on the gas pipe.
2.5 SYSTEM FILLING
The boiler and the heating system are filled
with water using the fill cock (fig. 6).
The charge pressure, with the system cold,
must be 1 bar.
Filling must be done slowly so as to allow
any air bubbles to be bled off through the air
valves.

2.10.1 Installation
The unit must be installed in the main living
room. For installation, follow the assembly
instructions inserted in the package. At this
point, with the selector knob on ( ), the
installer can adjust the basic parameters set-
tings according to the individual needs (point
2.10.2). If there is a thermostatic radiator
valve fitted, this m st be set to maxim m.
2.10.2 Installation settings
The settings for the basic operating para-
meters for individual needs are reported in
the instruction leaflet supplied with the
"Logica Remote Control" and in the section
reserved for the user in this manual.
For further adjustments which can be car-
ried out by the installer, the "Logica Remote
Control" offers a level of service and para-
meterising which can only be accessed
through a special combination of buttons.
To activate this level of service or parame-
terising press buttons and least 5
seconds. This will activate the parameteri-
sing level. Then use the same arrow buttons
to select the individual input lines and adjust
the values with or .

Heating takes place up to this pre-set value if the plant is activated in standby
(e.g. holidays).
In this way, the building antifreeze function is active, preventing an excessive
lowering of the ambient.
This parameter regulates the temperature of the automatic summer/win-
ter switch-over.
This parameter de-activates the ambient influence and as a result all the
optimisations and adaptations.
If a valid external temperature is not transmitted , the controller switches to
the pure ambient control guide variable.
If the ambient controller is used only as a remote control (placed in the refe-
rence room and without an external sensor connected), the value must be
set at 0 (zero).
If the change in ambient temperature from the pre-set value remains high
during the entire day, the influence must be increased. If the ambient tem-
perature is around the pre-set value (control oscillation), the influence must
be reduced.
Note: If the ambient temperat re infl ence constant is set at 0, the adap-
tation of the heating c rve is deactivated. In this case, parameter 57 will
have no effect at all.

The delivery temperature is limited to the maximum set value.
The increase per minute of the prescribed delivery temperature value sent

With the activation of the adaptation, the pre-set value transmitted to the
boiler regulator is adapted to the effective heat need.
The adaptation functions with both the atmospheric guide with ambient
influence and with pure ambient control.
If the "Logica Remote Control" is set as a remote control only, the adaptation
must be is deactivated.
If the switch-on time optimisation is active, the "Logica Remote Control" modi-
fies the heating gradient until it finds the optimum heating point
0 = off 1 = on
The "Logica Remote Control" selects the switch-on time such that the set
value has more or less been reached at the start of the usage time.
The more severe the night-time cooling, the earlier the heating time starts.
Example: Current ambient temperature 18.5°C
Nominal ambient temperature 20°C
Heating gradient 30 min/K
Presetting of switch-on time:
1.5 K x 30 min/K = 45 minutes
00 means that the switch-o time has not been pre-set (function disabled).
If the switch-off time optimisation is active (value > 0), the "Logica Remote

The gradient of the characteristic heating
curve is imposed on the current value “15”
of Logica. Increasing the gradient as shown
in the drawing of fig. 17, the delivery tempe-
rature increases in correspondence to the

The "Logica Remote Control" can be connec-
ted to an external temperature sensor availa-
ble a an optional extra (code 8094100). This
configuration ensures and maintains the
required temperature constant in the room.
The ambient temperature is, in fact, indicted
and evaluated as the calculated mean of the
value measured inside and outside the dwel-
ling. For installation, follow the assembly
instructions inserted in the package.

3.1 ELECTRONIC BOARD
The electronic boards are manufactured in
compliance with the EEC 73/23 low-voltage
directives. They are supplied with 230V and,
through a built-in transformer, send a volta-
ge of 24V to the following components: gas
valve, safety stat, C.H. and D.H.W. sensor,
external temperature sensor (optional),
modulator, flow switch safety valve, water
pressure transducer, flue gas thermostat,
room stat or “Logica Remote Control”.
An automatic and continuous modulation
system enables the boiler to adjust the heat
output to the various system requirements
or the User’s needs. The electronic compo-
nents are guaranteed against a temperatu-
re range of 0 to +60°C.
3.1.1 Fa lt finding
The indicator leds signalling irregular
and/or incorrect operation of the equip-
ment are indicated in fig. 18.
3.1.2 Devices
The electronic board is equipped with the
following devices:
“POT. RISC.” trimmer (10 fig. 19)
Sets the maximum heating power value.
To increase the value turn the trimmer
clockwise; to reduce the value turn the
trimmer anticlockwise.
“POT. ACC.” trimmer (6 fig. 19)
Trimmer to vary the pressure level upon
ignition (STEP), of the gas valve.
According to the type of gas for which
the boiler is equipped, the trimmer must
be regulated so as to obtain a pressure
of approx. 3 mbar at the burner for
methane gas and 7 mbar for propane
gas (G31). To increase pressure, turn
the trimmer clockwise; to reduce pres-
sure, turn the trimmer counterclockwi-
se. The slow ignition pressure level can
be set during the first 3 seconds fol-
lowing burner ignition.
After setting the press re level pon
ignition (STEP) according to the type of
gas, check that the press re for hea-
ting is still at the val e previo sly set.
“MET-GPL” connector (7 fig. 19)
When the connector is not connected
up the boiler is ready to operate on
NATURAL GAS. With connector installed
for PROPANE fuelled operation.
“ANN. RIT.” connector (5 fig. 19)
In the heating phase, the electronic board
is programmed to include a burner tech-
nical delay interval of approx. 90 seconds,
which occurs both at system cold star-
ting and at subsequent re-ignitions. The
aim is to overcome the problem of repea-
ted ignitions and turning off with very
short time intervals between. This could
occur in particular in systems presenting
high head losses. At each restart after
the period of slow ignition, the boiler will
set itself for about 1 minute at the mini-
mum modulation pressure, and will then
move to the heating pressure value set.
When the connecting link is inserted,
both the programmed technical pause
and the period of operation at minimum
pressure in the startup phase will be can-
celled. In this case, the times elapsing
between turning off and subsequent re-
ignition will depend on a temperature dif-
ference of 5°C detected by the SM sen-
sor (heating flow sensor).
DIP SWITCH (13 fig. 19)
Check that the cordless plugs are inser-
ted in the position indicated:
“Mod reg Sel.” connector (14 fig. 19)
W ith the bridge disconnected the boiler
is predisposed to function with the SIT
gas valve, and with the bridge connected
it is predisposed to function with the
HONEYWELL gas valve.
“Albatros” connector (15 fig. 19)
The bridge must always be disconnected.
It is connected only when multiple boilers
are installed in a sequence/cascade.
ATTENTION: It is essential that the opera-
tions described above be carried o t by
a thorized technical staff.

3.2 TEMPERATURE SENSOR
AND WATER PRESSURE
TRANSDUCER
Tables 3 - 3/a show the resistance values
(Ω) that are obtained on the sensor as the
temperature varies and the transducer
values obtained as the pressure varies.
When sensor (SM) is interr pted, neither
of the boiler's heating services will f nc-
tion. With D.H.W. (SB) sensor interr p-
ted, the boiler will only work in heating
mode.
3.3 ELECTRONIC
IGNITION
Ignition and flame detection is controlled
by two electrodes located on the burner.
These guarantee maximum safety with
intervention times, for accidental swit-
ching off or gas failure, of within one
second.
3.3.1 Operating cycle
Rotate the selector knob to summer or win-
ter, and verify that green led ( ) lights up to
confirm the presence of voltage.
The boiler is now ready to start working
upon demand for heating or drawing off
of D.H.W.; a discharge current is sent to
the ignition electrode through the pro-
grammer, and the gas valve opens at the
same time.
The burner must be ignited
within 10 seconds.
However, it is possible
for ignition failures to occur, with conse-
quent activation of signal indicating that the
control box has “locked out”.
Gas fail re
The control box runs through the cycle
normally sending electric power to the
ignition electrode. The electrode conti-
nues spark discharge for a maximum of
10 sec.If the burner does not light, the
lock-out indicator will light up.

This may occur upon first ignition or
after long periods of boiler lay-off when
there is air in the pipes. It may be caused
by the gas cock being closed or by one of
the valve coils having a break in the win-
ding, so that the valve cannot open.
Ignition electrode fails to spark
In the boiler, only the gas to the burner
is seen to open. After 10 sec. the war-
ning light indicating equipment “lock-
out” lights up.
This may be due to a break in the wire of
the electrode or to the wire not properly
fastened to the electric terminal of the
control box;
No detection of flame
The continuous spark discharge of the
electrode is noted starting from ignition
even though the burner is lit.
After 10 seconds have elapsed, the
sparks cease, the burner goes out, and
the warning light indicating equipment
“lock-out” lights up.
There could have a break in the wire of
the sensing electrode or the electrode
itself is touching earth: the electrode is
worn out and needs replacing. The con-
trol box is defective.
When there is a sudden voltage failure, the
burner shuts out immediately; when power
supply returns, the boiler will start up again
automatically.
3.4 SYSTEM AVAILABLE HEAD
The head available for the heating plant is
shown as a function of the flow in graph in
fig. 20.
3.5 FLOW SWITCH SAFETY VALVE
A flow switch safety valve intervenes,
blocking the operation of the burner if the
boiler is without water due to the formation
of an air lock in the heat exchanger or if the
circulator is not working, or because the
“Aqua Guard” filter is obstructed with impu-
rities.
NOTE: If replacing the flow switch valve,
make s re that the arrow stamped on the
valve points in the same direction as the
flow of water.

4.1 D.H.W. PRODUCTION
The preparation of hot water is guaranteed
by the glass storage tank unit with magne-
sium anode for the protection of the boiler
unit and inspection flange for its control and
cleaning.
The magnesi m anode m st be checked
ann ally and s bstit ted when it is worn.
It is advisable to place a sluice gate at the
entrance of the D.H.W. tank unit which,
apart from the total closure, allows the reg-
ulation of the supply capacity.
If the boiler does not prod ce hot water,
make s re that the air has been released
by pressing on the man al vents after hav-
ing switched off the main switch.
4.2 GAS VALVE
The boiler, is equipped standard with the
SIT 848 SIGMA gas valve (fig. 22).
4.3 ADJUSTMENT OF HEAT
OUTPUT FOR HEATING
To adjust boiler heat output for heating pur-
poses, i.e., modifying the setting made at the
factory which is approximately 17 kW, use a
screwdriver to adjust the heating heat out-
put trimmer (8 fig. 23).
To increase working pressure, turn the trim-
mer clockwise; to reduce pressure, turn the
trimmer counterclockwise.
To determine boiler heat output setting,
check energy consumption by observing the
meter and then compare with the values
shown in Table 4; or checked with a digital
pressure gauge connected (segno +) alla
presa (7 fig. 23). Compare values with
those shown in Table 4.

4.5 DISASSEMBLY OF
EXPANSION VESSEL
To disassemble the expansion vessel, pro-
ceed as follows:
Make sure that the water has been emp-
tied out of the boiler.
Unscrew the connection and the locknut.
Remove the expansion vessel.
Before refilling the system, using a pressu-
re gauge attached to the valve make sure
that the expansion vessel is preloaded at a
pressure of 0.8 to 1 bar.
4.6 CLEANING AND
MAINTENANCE
Preventive maintenance and checking of
efficient operation of equipment and safety
devices must be carried out exclusively by
authorized technical personnel.
4.6.1 Chimney sweep f nction
To carry out the verification of combustion
in the boiler, turn the selector and stop on
the position ( ) until the orange led ( )
starts to flash intermittently (fig. 25).
From that moment the boiler will start func-
tioning in heating mode at the maximum
power, with switching off at 80°C and
restarting at 70°C.
Before activating the chimney sweep f nc-
tion make s re that the radiator valves or
event al zone valves are open.
The test may be carried out also during hot
water functioning. To do so it is enough,
after having activated the chimney sweep
function, to take some hot water from one
or more taps; after a few minutes the
request of the hot-water service feeler is
activated and it automatically switches on
