– D.H.W. CONNECTION (E & U)
Fit the supplied; pressure reducing valve
(17), check valve (16), and expansion
relief valve assembly (14) with its associated tundish (15), in the D.H.W. supply to
the appliance, the flow from this assembly should be connected to the cold water
inlet (E) via the flow regulator housing
supplied. Ensure the 12 l/min flow regulator (11) and gasket (1) supplied, are fitted
in the flow regulator housing. See fig. 5
and fig. 6 for installation details. It is
important that no isolating valve is fitted
between the expansion relief valve and
the inlet to the D.H.W. tank. Any additional
D.H.W. drain down tap fitted should be
positioned as low as possible to ensure
that at least 80% of the D.H.W. tank’s
capacity can be drained. If installed in a
Hard Water area, then a suitable device
should be fitted to treat the mains supply
to the appliance (Contact your Water Distribution Company for advice on suitable
devices). Fit the quarter bend (2) to the
hot water outlet (U) using the gasket supplied (1).
instructions are supplied with the products, but for immediate information
please contact GE Betz (0151 420
9563) or Fernox (01799 550 811)
directly.
– For long term protection against corrosion and scale, after flushing it is recommended that an inhibitor such as
Sentinel X100, or Fernox MB-1 or Copal
is dosed in accordance with the guidelines given in BS 7593.
Failure to flush and add inhibitor to
the system may invalidate the appliance warranty.
– It is important to check the inhibitor
concentration after installation, system
modification and at every service in
accordance with the manufacturer’s
instructions. (Test kits are available
from inhibitor stockists).
on the following information:
a) The available pump head is given in fig. 20.
b) The burner starts when the C.H. flow
reaches 400÷450 l/h. This safety condition is ensured by the flow switch.
c) The appliance is equipped with an internal by-pass that operates with system
heads (H) greater than 3 m. The maximum flow through the by-pass is about
300 l/h. If thermostatic radiator valves
are to be installed, at least one radiator
should be without a thermostatic valve
(usually the bathroom radiator).
d) A sealed system must only be filled by a
competent person using one of the
approved methods shown in fig. 6. The
system design should incorporate the
connections appropriate to one of these
methods.

Discharge Pipes and fittings
The position of any tundish must be visible
to the occupants and any tundish, drain
valve and discharge pipe and must be sited
– GAS CONNECTION (C)
Fit the gas cock (12) to the gas connection (R) using the gasket supplied (6).
2.4
WATER SYSTEMS - GENERAL
This appliance is designed for connection to
sealed central heating water systems.
Check that the mains water flow is sufficient
to produce the required DHW flow rate but
does not exceed 4 bar pressure.
Where the pressure exceeds 4 bar, a
mains pressure reducer must be fitted to
the incoming water supply near to the
stop cock and set to 4 bar.
2.4.1
Treatment of Water
Circulating Systems
– All recirculatory systems will be subject
to corrosion unless an appropriate
water treatment is applied. This means
that the efficiency of the system will
deteriorate as corrosion sludge accumulates within the system, risking damage to pump and valves, boiler noise
and circulation problems.
– For optimum performance after installation this boiler and its associated central heating system must be flushed in
accordance with the guidelines given in
BS 7593 “Tr eatment of wat er in
domestic hot water central heating systems”.
– This must involve the use of a proprietary cleanser, such as Sentinel X300
or X400, or Fernox Super floc. Full

The connections to the expansion relief
valve and temperature and pressure relief
valve should not be used for any other purpose.
See fig. 6 for example of the discharge
pipe(s) for the temperature and pressure
relief valve, and expansion relief valve terminations. Note: it is permitted to connect
discharge pipes together provided that the
joint pipe is sized to accommodate the
combined flow.

Expansion Vessel (C.H. only)
C.H. EXPANSION VESSEL – The integral
expansion vessel is pre-charged to a pressure of 1.0 bar, which should be checked
before the C.H. water system is filled.
This vessel is suitable for correct operation
of system capacities up to 82 litre capacity.
If the actual C.H. system volume is greater,
then an additional vessel must be fitted to
the system. For systems where the volume
is greater, the additional expansion vessel
volume can be determined by multiplying
the volume in excess of that which can be
accommodated by the appliance by the factor 0.901. BS 7074 gives further details
regarding C.H. expansion vessel sizing.

– If the terminal discharges into a pathway or passageway check
that combustion products will not cause nuisance and that the terminal will not obstruct the passageway.
– Where the lowest part of the terminal is fitted less than 2 m (78
in) above ground, above a balcony or above a flat roof to which people have access, the terminal MUST be protected by a purpose
designed guard. Terminal guards are available from Quinnell,
Barrett, and Quinnell, Old Kent Road, London. State model C2,
(G.C. Part No 382946).
– Where the terminal is fitted within 850 mm (34 in) of a plastic or
painted gutter, or 450 mm (18 in) of painted eaves, an aluminium
shield at least 1,500 mm (59 in) long must be fitted to the underside of the painted surface.
– The air inlet/outlet flue duct MUST NOT be closer than 25 mm (1
in) to combustible material.
– In certain weather conditions the terminal may emit a plume of
steam. This is normal but positions where this would cause a nuisance should be avoided.

with a slope of at least 5 mm per metre to
ensure drainage of condensation water.
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building’s sewer pipes.
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 equipped, install an adequate filter on the gas pipe.
Once the D.H.W. circuit is commissioned
the C.H. circuit can be filled via the external
filling loop. Ensure both the D.H.W. and C.H.
temperature controls are set to minimum,
and that there is no room thermostat
demand. Turn on the electrical supply
to the appliance, (see Section 2.10), and
turn the selector knob to the summer position. Open the filling loop’s C.H. isolating
valve and then the D.H.W. double check isolating valve (See fig. 2 & 5/a).
Once the green “1 bar” led lights up close
both isolating valves, and disconnect the
flexible hose from the D.H.W. double check
isolating valve. Check for leaks and free
rotation of the circulating pumps. The
appliance can then be commissioned by following the User Instructions.

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 settings according to the individual needs (point
2.10.2). If there is a thermostatic radiator
valve fitted, this must be set to maximum.
2.10.2 Installation settings
The settings for the basic operating parameters 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 carried out by the installer, the "Logica Remote
Control" offers a level of service and parameterising which can only be accessed
through a special combination of buttons.
To activate this level of service or parameterising press buttons
and
least 5
seconds. This will activate the parameterising level. Then use the same arrow buttons
to select the individual input lines and adjust
the values with

.
HEATING CIRCUIT SETTINGS
Antifreeze protection
"Pre-set ambient
temperature value"
51
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.
Summer/Winter switch-over
temperature
52
This parameter regulates the temperature of the automatic summer/winter switch-over.
Type of control:
0 = with ambient influence
1 = without ambient influence
53
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.
Influence of ambient temperature
54
If the ambient controller is used only as a remote control (placed in the reference 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 temperature is around the pre-set value (control oscillation), the influence must
be reduced.
Note: If the ambient temperature influence constant is set at 0, the adaptation of the heating curve is deactivated. In this case, parameter 57 will
have no effect at all.
10
Maximum limit of delivery
temperature
55
The delivery temperature is limited to the maximum set value.
Variation of the maximum speed of the
delivery temperature
56
The increase per minute of the prescribed delivery temperature value sent
in °C is limited to the imposed value.
Activation of adaptation
57
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.
Optimisation of
switch-on time
58
If the switch-on time optimisation is active, the "Logica Remote Control" modifies the heating gradient until it finds the optimum heating point
0 = off
1 = on
Heating gradient
59
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

00 means that the switch-o time has not been pre-set (function disabled).
60
If the switch-off time optimisation is active (value > 0), the "Logica Remote
Control" modifies the pre-set time until it finds the optimum switch-off time..
Reduced domestic hot
water pre-set value
61
The reduced pre-set value of the temperature of the domestic hot water allow
the required water temperature to be obtained outside the programmed
usage times (daily programme 8).
Domestic hot water load
62
0 = 24 hours/ day - Hot water is always available at the temperature set
with user parameter n°3.
1 = standard - Hot water according to the daily heating programme.
In the comfort areas of heating the temperature of the boiler unit is regulated to the value set with user parameter n° 3.
In the reduced areas of heating the temperature of the boiler unit is
regulated to the value set with parameter n° 61 of the service level.
2 = service disconnected
3 = second daily programme (8) - Every day of the week the temperature of
the hot water is set according to programme 8. In this case there is a
single programming for all the days of the week and three time zones are
available. In the time spans set the temperature of the boiler unit is regulated according to that set in parameter n°3. In the remaining hours the
boiler unit is controlled to the temperature set with parameter n° 61 the
of service level.

Input function terminal 3-4
64
The freely programmable input (terminals 3-4) allows three different functions
to be activated. The parameter has the following significance:
1 = If an external sensor is connected, the display will show the temperature
of the external sensor ( _ _ = no sensor connected, function disabled).
2 = With an external contact, it is possible to switch-over to "reduced preset value of the ambient temperature".
3 = With an external contact, it is possible to switch-over to "reduced preset value of the antifreeze ambient temperature" (short circuit 0 0 0 or
interruption _ _ _ ). The display shows the current status of the external
contact.
Modo de acção do contacto externo

This function allows the hot water to be brought to a high temperature once
a week in order to eliminate eventual pathogenic agents.
It is active every Monday for a maximum duration of 2.5 hours at a delivery
temperature of 65°C.
0 = not active

2.11.3 Gradient of the characteristic
heating curve
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 temperature increases in correspondence to the
outside temperature.
2.12
EXTERNAL TEMPERATURE
SENSOR
The "Logica Remote Control" can be connected to an external temperature sensor available 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 dwelling. For installation, follow the assembly
instructions inserted in the package.
12
Example: Choosing a gradient of 15 with an outside temperature of –10°C
we shall have a delivery
temperature of 60°C.

CHARACTERISTICS
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 voltage 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 components are guaranteed against a temperature range of 0 to +60°C.
3.1.1
Fault finding
The indicator leds signalling irregular
and/or incorrect operation of the equipment 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 pressure, turn the trimmer counterclockwise. The slow ignition pressure level can
be set during the first 3 seconds following burner ignition.
After setting the pressure level upon
ignition (STEP) according to the type of
gas, check that the pressure for heating is still at the value previously 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 technical delay interval of approx. 90 seconds,
which occurs both at system cold starting and at subsequent re-ignitions. The
aim is to overcome the problem of repeated 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
Flashing red led, fan.
30 minutes after the fan has switched off,

set itself for about 1 minute at the minimum 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 cancelled. In this case, the times elapsing
between turning off and subsequent reignition will depend on a temperature difference of 5°C detected by the SM sensor (heating flow sensor).

With 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.

ELECTRONIC IGNITION
Ignition and flame detection is controlled
by two electrodes located on the burner.
These guarantee maximum safety with
intervention times, for accidental switching off or gas failure, of within one
second.
3.3.1
Operating cycle
Rotate the selector knob to summer or winter, 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 programmer, 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 consequent activation of signal indicating that the
control box has “locked out”.
– Gas failure
The control box runs through the cycle
normally sending electric power to the
ignition electrode. The electrode continues 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 winding, 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 warning light indicating equipment “lockout” 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;
PREVALENZA RESIDUA (mbar)
– No detection of flame
The continuous spark discharge of the
electrode is noted starting from ignition
even though the burner is lit.
Af t er 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 control box is defective.

USE AND MAINTENANCE
4.1
D.H.W. PRODUCTION
The preparation of hot water is guaranteed
by the glass storage tank unit with magnesium anode for the protection of the boiler
unit and inspection flange for its control and
cleaning.
The magnesium anode must be checked
annually and substituted 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 regulation of the supply capacity.
If the boiler does not produce hot water,
make sure that the air has been released
by pressing on the manual vents after having switched off the main switch.
The temperature and pressure relief valve
and expansion relief valves should not be
used for venting air out the system.
To drain the D.H.W. circuit, turn off the gas
and electricity supplies and close the
D.H.W. supply isolating valve to the appliance. Connect a hose to the D.H.W. discharge
cock (See fig. 2) and feed to a suitable
drain. Open a hot water tap, and then open
the D.H.W. discharge cock, to drain the
tank.

ADJUSTMENT OF HEAT
OUTPUT FOR HEATING
To adjust boiler heat output for heating purposes, i.e., modifying the setting made at the
factory which is approximately 17 kW, use a
screwdriver to adjust the heating heat output 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.

DISASSEMBLY OF
EXPANSION VESSEL
To disassemble the expansion vessel, proceed as follows:
– Make sure that the water has been emptied out of the boiler.
– Unscrew the connection and the locknut.
– Remove the expansion vessel.
Before refilling the system, using a pressure gauge attached to the valve make sure
that the expansion vessel is preloaded at a
pressure of 0.8 to 1 bar.
er functions at the maximum temperature
always with the primary controlled between
80°C and 70°C. During the entire duration
of the testing the hot water taps must
remain open. After verifying the combustion
the boiler should be switched off by placing
the selector on the (OFF) position; then
return the selector to the desired function.
Inspect the burner and if necessary clean
using a soft brush, taking care not to damage the
front insulation.
Check the Ignition/ionisation electrode,
check the gap (4mm+/- 0.5mm)
Before reassembly inspect all seals and
replace as required.
ATTENTION: After about 15 minutes the
chimney sweep function automatically
deactivates.

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 function
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 functioning in heating mode at the maximum
power, with switching off at 80°C and
restarting at 70°C.
Before activating the chimney sweep function make sure that the radiator valves or
eventual 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
the led (
). Even in this condition the boil-
ROUTINE SERVICING
To ensure continued efficient operation of
the appliance, it is recommended that it is
checked and serviced at regular intervals.
The frequency of service will depend on the
particular installation
and conditions of usage, but in general once
a year should be adequate.
It is the law that a competent person such
as a CORGI registered engineer, must carry
out any service work.
4.7.1
Combustion Check
Incorporated into the flue elbow or vertical
adaptor is a sampling point.
The grey plastic cap should be unscrewed
and the flue gas sampled using a flue gas
analyser.
During the test the boiler can be operated
in “chimney sweep mode” see 4.6.1.
The correct CO2 reading can be found in
section 4.4.
4.7.2
Combustion Chamber
Remove any loose debris from the combustion chamber using a soft brush and a vacuum cleaner. Take care not to damage the
rear insulation panel.
4.7.4
Condensate Trap
The condensate trap would not normally
require removal during service, but can be
checked whilst the burner assembly is
removed.
Carefully pour water into the heat exchanger and check that it flows freely to the drain.
Should it require removal, firstly remove the
two wire clips securing the condensate
drain rubber pipe to the heat exchanger
and the condensate trap.
Remove the pipe.
Remove the 1/2 “ nut securing the condensate trap to the combustion compartment.
Disconnect the drain pipe from the trap.
Clean the trap and refit in reverse order.
Burner inspection
Remove the burner as described in section
6.5.
