In B23P configuration (if installed inside), do not install the apparatus in
rooms used as bedrooms, bathrooms, showers or where there are open
vent stacks without own air exchange. The boiler must be installed in an
adequately ventilated room. See the UNI-CIG 7129-7131 and UNI 11071
standards for detailed instructions on installing vent stacks, gas pipes and
to ventilate the room.
In C configuration the boiler can be installed in any type of room and there
are no limits to aeration conditions and size of room.
FOR CORRECT INSTALLATION, WE REMIND YOU THAT:
- The boiler must not be installed over a stove or any other cookingequi-
pment or within a bathroom.
- minimum spaces are to be left in order to allow maintenance operations:
at least 5,0 cm every side and 20 cm under the boiler
- it is forbidden to leave inflammable substances in theroom
- suitably fire line any heat-sensitive walls (e.g.: wood lined).
A support plate and integrated pre-installation template are provided for
with the boiler (FIG. 1.1).
Mounting instructions:
- fix the boiler support plate (F) with the template (G) to the wall and usea
plumb to check that it is perfectly horizontal
- trace out 4 holes (Ø 6 mm) for fixing the boiler support plate (F) and 2

PUMP DUTY
Exclusive Green HE boilers are fitted with a variable speed circulation unit
that is already connected up in terms of plumbing and electrics, and the
usable performance it provides is shown in thegraph.
The boilers are fitted with an anti-blocking system that starts an operating
cycle every 24 hours when not used, irrespective of the position of the func-
tion selector.
The “anti-blocking” function is only active when the electrical power
supply to the boiler is on.
Operating the appliance pump without water is forbiden
VARIABLE SPEED CIRCULATION UNIT
The modulating circulating function is only active for the heating function.
When the three way valve switches to DHW the pump works at max speed
unit is set at maximum speed. The modulating circulation function applies
only to the boiler circulation unit and not to circulation units on anyexternal
devices connected to it (e.g. booster circulationunit).
Any of 4 operating modes can be chosen, depending on situations and the
type of plant.
By accessing parameter 90 in the technical menu, one of the following pos-
sibilities can be chosen:
1 -VARIABLE SPEED CIRCULATION UNITWITH PROPORTIONAL MODE
(41 <= P90 <= 90)
2 -VARIABLE SPEED CIRCULATION UNITWITH CONSTANT DT MODE
(2 <= P90 <= 40)
3 - VARIABLE SPEED CIRCULATION UNIT WITH MAXIMUM FIXED
MAXIMUM SPEED MODE (P90 = 1)
4 –EXCEPTIONALUSEOF ASTANDARDCIRCULATIONUNITWITHOUT
SPEED ADJUSTMENT (P90 = 0)
1 -VARIABLE SPEED CIRCULATION UNITWITH PROPORTIONAL MODE
(41 <= P90 <= 90)
In this mode the boiler’s board determines what flow rate curve to adopt
according to the instantaneous power supplied by the boiler.
The boiler controller breaks down the power range within which the boiler
operates in heating mode into various levels. Depending on the power level
in use when heating, one of the speeds available is selected automatically
according to logic: Max power = HIGH SPEED, Min power = LOW SPEED.
This is used on all types of plants where the machine’s power has been
correctly balanced with the plant’s real needs.
Operationally:
- Access parameter 90
- Set the parameter = 41
Note :The Parameter 90 = 41setting is recommended by the manufacturer.
Values exceeding 41 are used in specific cases.
3 - VARIABLE SPEED CIRCULATION UNIT WITH MAXIMUM FIXED
MAXIMUM SPEED MODE (P90 = 1)
In this mode the modulating circulation unit works constantly at maximum
speed.
It is used on plants with a high load loss in which the boiler’s headmust be
usedasmuchas possibleinorder to guaranteesufficientcirculation(plant
flow rate at maximum speed lower than 600 litres perhour).
This is used when bottles of mixture are involved, with high flow rates in
the circuit downstream.
Operationally:
- Access parameter 90
- Set the parameter = 1
4 –EXCEPTIONAL USE OF A STANDARD CIRCULATION UNITWITH-
OUT SPEED ADJUSTMENT (P90 = 0)
This mode must be used in exceptional cases in which the boiler is to
be used with a traditional circulation unit without a speed adjustment. It
presupposes that the adjustable speed circulation unit has been removed
and replaced with a non-adjustable speed circulation unit.
Warning !!!! The BE06 board connected to connector CN9 must be
removed and replaced with a connector with a jumper to be inserted into
connector CN9. This latter connection is obligatory and if not formed
may cause the system to malfunction.
Operationally:
- Access parameter 90
- Set the Parrameter = o
CONFIGURATIONS RECOMMENDED BY THE MANUFACTURER
2 -VARIABLE SPEED CIRCULATION UNITWITH CONSTANT DT MODE
(2 <= P90 <= 40)
In this mode the installer sets the T value to be maintained between the
delivery and return (e.g. if a value of 10 is entered, the circulation unit’s
speed will change to implement a plant flow rate aimed at maintaining the
 between the inlet and outlet of the heat exchanger AT10 Deg C
By periodically sampling values provided by the boiler delivery/return
sensors, the board increases or decreases the circulation unit’s speed and
therefore the plant’s flow rate. If the sampling shows a T value lower than
that set, the speed is reduced until the T increases to the value set. Vice-
versa if sampling is higher than the value set, the speed is increased.
This is used for direct high temperature plants (typical of replacement),
where the boiler is not thermostatically controlled, and where a calculated
delta T can be set.
When working with a constant delivery temperature and attainment of
stabilisingtheambientconditions,theaveragetemperatureoftheradiators
tends to increase. By keeping T constant, the reduction in the flow rate is
obtained by changing the operating curve, which produces a lower return
temperature thatinturn favours highboiler performance andthe reduction
of electricity consumption.
Operationally:
- Access parameter 90
- Set the parameter at a value between 2 and 40 (normally between 10
and 20).

and complies with EN 60335-1 standard. Connect the boiler to a safe earth
circuit according to current legislation.
Live and neutral (L-N) connections should also be respected.
The boiler can operate with phase-neutral or phase –phase power supply. For
floating power supply, without an earth-bonded conductor, it is necessary to
use an insulation transformer with secondary anchored to ground.
The earth conductor must be a couple of cm longer than the others.
Gas and/or water pipes may not be used to earth electrical equipment.
The installer is responsible for making sure that the appliance has an
adequate earth system; the manufacturer shall not be held liable for
eventual damages caused by incorrect usage or failing to earth the
boiler.
Use the supplied power cable to connect the boiler to the mains power
supply.
Connect the ambient thermostat and/or time clock as shown in theelectrical
diagrams.
When replacing the power cable, use a HAR H05V2V2-F cable, 3 x 0,75
mm2, Ø max. external 7 mm.
8 - FILLING AND EMPTYING THE SYSTEM
The central heating system can befilled uponce thewatermains havebeen
connected.
This must be done while the installation is cold by:
- Turn the caps of the lower (A) and upper (E) automatic bleed valves two
or three turns; leave A and E valve caps open for continual air venting
(FIG.1.9);
- Making sure the cold water inlet tap is open
- Opening the filling tap (B, on the boiler for until the pressure on the
gauge (C) is between 1 and 1,5 Bar (BLUE ZONE) (FIG.1.9).
Close the filling tap after filling.
The boiler is equipped with an efficient air separator sothat there is noneed
to do anythingmanually.
The burner only ignites when air venting has finished.
NOTE: air extraction from the boiler takes place automatically, through two
automatic bleeding valves, A and E.
The first is situated on the pump, while the second is inside the air chamber.
NOTE the boiler is also equipped with a semi-automatic filling system. The
first system-filling operation must be carried out by opening tap B with the
boiler turned off.
Emptying
Before starting to empty the boiler, isolate power switch for the system (off)
Close the isolation devices for the thermal system
- Loosen the system outlet valve (D)manually
- The water from the system is discharged through the outlet collector (F).

EXHAUSTION CONFIGURATIONS (Fig. 1.11-1.12)
Boiler is homologated for the following exhaustion configurations:
B23P-B53P - Suction in room and discharge outside
C13 - Concentric wall exhaustion. Pipes can separately start from boiler,
but outlets must be concentric or close enough to be subject to similar wind
conditions (within 50 cm)
C23 - Concentric exhaustion in common chimney (suction and exhaustion
in the same chimney)
C33 - #ONCENTRIC ROOF EXHAUSTION. /UTLETS LIKE #13
C43 - Exhaustion and suction in common separate chimneys, but subject
to similar wind conditions
C53 - 7 A LL O R R OO F S EPA R A T E E XH A US T I O N A ND SU C T I O N I N D I FF E R E N T P R E SSU R E A R EA S .
Exhaustion and suction must never be located on opposite walls
C63-Exhaustionandsuctionwithseparatelycertifiedandsoldpipes(1856/1)
C83 - Single or common chimney exhaustion and wall suction
C93 –Exhaust on roof (similar to C33) and air
Refer to regulations in force for exhaustion of combustion products.
Boiler is provided for without fume exhaustion/air suction kit, since forced
draught sealed chamber accessories can be used, as they better adapt to
installation characteristics.

Adjust the ambient thermostat to the required temperature (approx. 2o—
#). If there is a demand for heating water, the boiler starts and the symbol
is shown on the display (&IG. 1o). The boiler will remain working until the
set temperatures are reached, after which it will go on stand-by. In the
event of ignition or operating faults, the boiler will perform a “safety stop
The flame symbol will go out and the fault code and will be displayed

theboiler is attemptingtosolveon its own (temporary stoppage).If theboiler
does not resume normal operation, two things may happen:
Case A (Fig. A)

case, proceed as described in point 2.
Case B (Fig. B)
and a different alarm code are displayed together with .
In this case, proceed as described in point 3.
Case C
Alarm 91 - Contact the Technical Assistance
The boiler has a self-diagnosis system which, on the basis of the hours to-
talised in particular operating conditions, signals the need for maintenance
or cleaning of the primary exchanger (alarm code 91). After cleaning using
the kit supplied as an accessory, reset the hour counter as follows:
- disconnect the mains power supply
- remove the screws and hooks securing the electricalcover
- remove connector J13 (see wiringdiagram)
- power the boiler and wait for alarm 13 to appear on thedisplay
- disconnect the power supply and reconnect connector J13
- put back the electrical cover and restart the boiler
N.B.:perform the counter reset procedure every time theprimary exchanger
is thoroughly cleaned or replaced.

PARAMETER 03. Type of building
In order to calculate delivery temperature, the temperature control system
does not directly use the external temperature value but considers the heat
insulation of the building: in well-lagged buildings, external temperature
variations affect the ambient temperature less than they do inbadly-lagged
buildings. Use parameter 3 to set the heat insulation level of the building
according to the followingscheme:
If, from your calculations, you obtain an intermediate value between two
curves, we suggest choosing the compensation curve closest to the value
obtained.
Example: if the value obtained from the calculations is 8, this is between
curve 7.5 and curve 10.In this case, choose the closest curve, which is 7.5.
PARAMETER 51. Type of heat request
IF AN AMBIENT THERMOSTAT IS CONNECTED TO THE BOILER, SET
PARAMETER 51 = 0 (graph 2).

The boiler can be transformed to use propane gas using a special kit.
&OLLOW THE INSTRUCTIONS GIVEN HERE BELOW FOR DISASSEMBLY:
- Switch off the power to the boiler and turn off the gas cock
- Remove the panel and casing
- Lift up and rotate the instrument panel
- /PEN THE AIR BOX COVER
SPRINGS PLACED AT 12o—AS SHOWN IN THE (Fig. 1.20)
- Reassemble gas ramp and silencer, working viceversa.
- Check the number of times the fan turns
- Switch on the power to the boiler and turn on gas cock again
- &ILL IN AND STICK ON THE ACCOMPANYING TRANSFORMATION DATA LABEL
- Close the air boxcover
- Close up the instrument panel again
- Reassemble the casing and panel
Programme the “Gas type” parameter and regulate the boiler following the
instructions in the “Adjustments” section.
Transformation must be done by qualified personnel only.
After completing transformation, regulate the boiler again following
instructions given in the specific paragraph and apply the new identi-
fication label from the kit.
General maintenance
Be particularly careful when handling the mixer: the Clapet juts out from the
body so that the mixer must be laid on the air inlet side (flap area) or make
sure the Clapet is inside the body if it has to be laid on the Clapet side.
The Clapet must never have to bear the weight of the mixer.
Clean the Venturi from any dust with an aspirator during the annual system
cleaning.Check that flap and Clapet are working correctly (all open at rated
flow, all closed at minimum flow)
20–CHECKING COMBUSTION PARAMETER
Do as follows to analyze combustion:
- GOTO '!5').' &3%26)#% ANDSETTHECOMBUSTIONANALYSISPASSWORD
as given in paragraph “Adjustments”
- insert the analyzer probe into the specific openings on the air box, after
removing screw B and cap C.
The fumes analysis probe must be introduced as far as possible
- screw the analyzer setscrews into the fumes analysis opening
- the first display gives the reading of the number of turns corresponding to
maximum heating power set on the boiler (see paragraph “Adjustments”
item P23)
After turning the domestic hot water temperature selector again the boiler
will ignite to check combustion
- check combustion
- refer to the “Adjustments” paragraph if the boiler has to be gauged
- remove the analyzer gauge and close the combustion analysis openings
by theirscrews.
