It is important that a good flue duct be
installed in order to avoid backflow or
irregular outlet of the gases. The
necessary precautions should also be
taken to ensure that no condensation
produced in the flue duct enters the boiler.
B11 BS-type boilers: They are equipped with a
flue spillage limit thermostat which should never
be unplugged. If the boiler detects an inadequate
evacuation of flue gases, the gas supply will be
shut off an the corresponding fault code will be
displayed. See section under "Fault Codes" in
the User's Manual.
B11-type boilers: These are not equipped with
the above control devide. This type of boiler may
only be installed in a room separate from
residential premises and with suitable ventilation
direct to the outside.
Room-sealed boilers: Set up the various
components supplied as shown in Fig. 3.
Connect the bend to the boiler flue socket in the
desired configuration. If it does not coincide with
the fixing holes, it is best to drill the bend flange.
If the outer duct has been shortened, the inner
duct must also be cut to the same length.
Make a Ø 110 mm opening in the outside wall
and allow the straight run of pipe to slightly slope
outwards.
Important: Room-sealed boilers are CE
approved for use with the following types of
flue ducts. See Fig. 4.
C12: Horizontal flue duct direct to the outside
air. Maximum of 3 metres in straigth line.
C32: Vertical conduit with outlet to roof. If can
be attached to the concentric fitting with
vertical outlet. In this case, the maximum
length alowed in a straight line is 8 metres.
C42: Horizontal flue duct connected to a
common stack 3CE type. (Common stack
for room-sealed boilers).
C82: Double horizontal conduit. Air inlet from
outside and gas outlet to a single common
conduit. Maximum length from the end of
the air inlet to the gas outlet: 10 metres.
In all cases, please note that for every 90 °C flue
bend fitted, the above dimension should be
reduced by 0,7 metres.
Electrical Connection
A connector (socket) like the one shown in Fig.
5 is included in the boiler. To connect it, proceed
as follows:
– Remove the connector from the boiler.
– Remove the protective cover of the terminal
strip.
– Connect the Live lead to terminal "L1".
– Connect the earth lead to the terminal marked
.
– Connect the Neutral lead to terminal "N".
If the installation has a room thermostat, remove
the jumper across terminals T1 and S3 and
connect the thermostat wires to them (minimum
2
cross-section 1 mm
).
If the thermostat features an anticipatory resistor,
connect it to terminal "T2", as shown in Fig. 5.
Once the connections have been completed,
put the connector back in the boiler. See Fig. 6.
It must be pushed fully home. Remember that if
the power supply to the boiler is to be isolated,
this connector must be unplugged.
Important: The earth connection is
obligatory.

System Filling
Check the position of the CH Flow and Return
valves (Fig. 9). Both valves must be fully open.
To open them, turn anti-clockwise. Increase the
circuit pressure up to 1.5 bar. See Fig. 10
Ensure that the air valve is open. See Fig. 12.
Ensure that the pump rotates. If it does not rotate,
press a screwdriver against the slot on the shaft-
end and turn it. See Fig. 13.
Gas
Ensure that the gas inlet cock (18) is open. See
Fig. 2). To open it, turn anti-clockwise.
Programming and Operating
The green lamp indicates that the electrical
supply is reaching the boiler. See Fig. 14.
The water pressure should be 1.5 bar. If it is
under 1 bar, the red indicator lamp will light up,
the fault code 03 will be displayed on the screen
and the burners will not ignite. See Fig. 15.
Central Heating Mode
Press
for a moment to programme the boiler
for Heating and Domestic Hot Water. The Hot
mode has priority over Central Heating.
If there is demand for Heating, the boiler will start
up. The temperature will increase until the
maximum value selected is reached (80 °C). The
data shown in Fig. 16 will be displayed.
Domestic Hot Water Mode
Press
for a moment to programme the boiler
for Domestic Hot Water. If a hot water tap is
opened, the boiler will start up. The temperature
will rise until reaching the maximum value
selected (55 °C). The data shown in Fig. 17 will
be displayed.
Stop
Press
for a moment to cancel the service
programmed (Fig. 18). In this position, a
permanent frost protection feature and pump
seizure system are activated (see section under
"Permanent Monitoring System").
If for any reason the boiler goes into "lock-out",
the red indicator lamp will light up. See Fig. 19.
Press
for 3 to 5 seconds and the boiler will
attempt a new ignition cycle. Please refer to the
"Fault codes" section in the User's Manual.
Programming Options
The temperatures programmed are: 80 °C for
Central Heating and 55 °C for Domestic Hot
Water. However, the factory-set temperature
may be altered as follows:
Central Heating Mode
Press
for a moment. See Fig. 20.
The temperature digits will immediately flash for
10 seconds.
While the digits are flashing, press
wish to increase the temperature, or
wish to decrease it.
Once the new temperature has been set, it will
be automatically stored. The temperature range
goes from 30 °C to 90 °C.
Domestic Hot Water
Press
for a moment. See Fig. 21.
The temperature digits will immediately flash for
10 seconds.
While the digits are flashing, press
to increase the temperature, or
decrease it.
Once the new temperature has been set, it will
be automatically stored. The temperature range
goes from 40 °C to 60 °C.
Standard Programme
Press
for a 10 seconds to re-establish the
factory-set programme. See Fig. 18.
Output
The boiler is delivered pre-set to provide 22 Th
in the Central Heating Mode. This output may
R-30/30:
From 8,000 to 30,000 kcal/h.
R-30/30 F: From 8,000 to 27,000 kcal/h.
If you wish to adapt the output to the needs of
the installation, proceed as follows:
Keep the three buttons
one second. The symbols shown in Fig. 22 will
be displayed for 30 seconds.
Press
and select the required output.
The output levels are as follows:
Model
Output Level (therms)
R-30/30, & P
8
10
12
R-30/30F & FP
8

The new output selected will be stored in the
memory by pressing again
neously.
Permanent Monitoring System
When the boiler is left on "Stand-by". Fig. 18, and
regardless of any other conventional sageties,
a permanent protection system will operate,
giving the following services.
Pump Seizure Protection
It activates the pump for 15 seconds every 6 hours.
Anti-inertia
Following every Heating and/or Domestic Hot
Water cycle, the pump continues to run for a
short period of time.
Built-in Frost Protection
If the temperature of the Heating drops to 7 °C,
the pump is turned ON until it rises to 9 °C.
Built-in Super Frost Protection
If the temperature of the Heating Circuit drops to
5 °C in extreme weather conditions, the
programme activates not only the pump but also
the igniton system, at minimum output. The
burners will go out after 30 minutes or when the
temperature rises to 35 °C.
