WATER CONNECTION
Fit the supporting hooks and attach the assembly template, moving it up to the wall; fit all the pipes, starting
with the end pipe fittings already mounted on the template: system supply, system return, cold water, hot water,
any gas pipes and electric mains leads with room thermostat.
Once the pipes have been fitted, the end pipe fittings can be removed and ordinary caps fitted, ready for
hydraulic tests to be carried out. The template can be removed or, if left in place, will be embedded in the wall
once finishing operations have been completed (plaster and tiles); only the two supporting hooks will protrude
from the wall, as well as an opening for the connections. Attach the boiler to the hooks through the holes at the
back of the frame, pushing it up against the finished wall. Make the necessary hydraulic connections.
ADVICE AND SUGGESTIONS ON PREVENTING SYSTEM VIBRATION AND NOISE.
- Do not use pipes of reduced diameter.
- Do not use low-radius elbows or fittings that significantly reduce cross-section.
-Hot-flushing of the system is recommended in order to eliminate any impurities from the piping and
radiators (especially oil and grease) which might damage the circulator.

BOILER INSTALLATION
UNPACKING THE BOILER
1 Open the top of the carton and remove the
following parts:
Boiler tools and accessory pack
Document pack and wall template
Wall mounting template
Down-draft diverter
2 Break open the boiler carton with care. Do not
cut the carton, open with a knife: you could
damage the jacket.
Make sure that the surface on which the carton is
resting is protected so the boiler is not scratched
or damaged during unpacking.
PREPARING THE WALL
1 Use the supplied template to decide on boiler
positioning.
The template is the same size as the boiler plus
the spaces which need to be maintained around
it.
Note: When deciding on boiler position take into
account the flue terminal position.
2 Attach the template to the wall with adhesive tape
(make sure it is level) and mark the position of
the two holes used to fix the bracket to the wall,
the two holes for the upper part of the boiler and,
in the case of a rear-mounted fume outlet, the
flue hole.
Ifthereis to bea side fluecontinuewith the central
horizontal line of the flue along the wall towards
the side wall and then along the side wall for
160 mm. This is the position of the centre of the
flue hole.
3 Cut the 105 mm flue hole in the wall. Make sure
that it is horizontal. Drill the four fixing holes:
thesemustbe suitable for then. 9 plugs (supplied).
Fit the plugs.

INSTALLATION
To be carried out by qualified personnel.
The installation must be in compliance with the stipulations of the law regarding the evacuation of combustion
materials according to the REGULATIONS IN FORCE.
The gas fume evacuation must be effected with a pipe of a diameter not less than that required by the boiler
and it must be connected to a flue pipe suitable for the capacity of the installation.
For connection of appliances to smoke conduits:
a) they must be easy to dismantle;
b) they must be sealed and of a material able to resist the products of combustion and their possible
condensation;
c) they must not have regulation devices (gate valves). If such devices are already in operation they must be
eliminated;
d) the connection itself must not protrude inside the flue pipe but stop before the internal face of the same.
GAS CONNECTION
Carry out the gas connection in accordance with the regulations in force.
The boiler must be connected to the installation with a rigid metal pipe or a flexible stainless steel pipe with
continuous wall of the approved type. The flexible corrugated metal pipes must be installed in such a way that
their length, in a state of maximum extension, is not greater than 2000 mm. The boilers are calibrated and
tested to function with NATURAL GAS and LIQUID GAS, category II 2H3+, with rated pressures of 20 mbar,
28/30 mbar and 37 mbar respectively.
PUTTING THE BOILER INTO SERVICE
●Proceed with the clearing out of air.
●Check that there are no gas leaks (use a soapy solution or equivalent product).
SYSTEM FILLING
Open the feeding tap slowly until the system reaches a working pressure (indicated on the hydrometer) of 1.5
bar, then close it. Check that the automatic air bleed valve, on the circulator, has its cap loosened; run the
circulator repeatedly to eliminate any air in the circuit.
IGNITION
Open the gas tap and turn the selector switch to the desired position. The burner will ignite automatically.
Should the unit fail to ignite see if the lock-out indicator is on. If it is, turn the selector switch to RESET so that the
boilerrepeatstheignitionsequence.Then adjust heating and hot water temperature asdesiredviatheappropriate
controls.

CONNECTION TO THE CHIMNEY - VERSION XILO T 20 MS W TOP
The boiler is for combustion in a sealed chamber and does not require any special ventilation, it can also be located in
small rooms, lumber-rooms, laboratories. In addition, there are various possibilities for combustion fume evacuation
and external air intake; basically the boiler is designed for two types of fume evacuation/air intake:
●fume evacuation/air intake concentric pipes system,
●fume evacuation/air intake double pipes system.
In this way it is possible, by using suitable kits, to connect the boiler to concentric flues, ventilating flues,
separate flues, etc. Some possible solutions are indicated below.
FLUE EXHAUST CONNECTION

FLUE EXHAUST INSTALLATION
ATTENTION: Use only air intake/ fume evacuation kits produced by Lamborghini Caloreclima.
CONCENTRIC FLUE PIPE
Fit the concentric elbow pipe positioning it on the desired direction and insert on it the sealing gasket. Then fit
the appropriate diaphragm (see table below).
Fit the air intake and flue exhaust pipes, observing the distances indicated on the installation scheme. The flue
pipe should slope slightly outward.
DOUBLE FLUE PIPE
Maximum length of CONCENTRIC FLUE PIPE 3 mt.
Maximum length of DOUBLE FLUE PIPE
(Intake + Exhaust) 20 mt.
Installing an elbow to connect the boiler to the chimney will cause a
drop in pressure.
The values set out in the table below indicate the necessary
modifications to the length of the linear pipes.

ADJUSTMENTS
Note: For this calibration it is necessary to use a water column pressure gauge connected to the pressure
plug.
RADJUSTMENT OF OUTLET PRESSURE
Maximum pressure:
●Power the modulator with the proper voltage.
●By turning nut Bclockwise (use a 10 mm wrench), the outlet pressure increases.
Minimum pressure (adjust only after the calibration of the maximum outlet pressure has been completed):
●Disconnect modulator feeding.
●While blocking the nut Bwith a wrench, turn the screw Aclockwise to increase the outlet pressure.
After calibration:
●Check the maximum and the minimum pressures and adjust them if necessary.
●Fit the plastic cap C.
The boilers have a fast opening gas valve. The necessary calibration for gas delivery may be obtained from a
double modulator coil. Calibration of the slow ignition (pre-calibrated in the factory) is electronically done and
is adjustable (for optimising and for gas type conversion) by the trimmer RLA on the electronic board. The
necessary thermal output for the heating system can be regulated by manipulating the trimmer R MAX. All the
boilers are calibrated in the factory to release 70% of their maximum heating capacity. By removing the
jumper JP4, the waiting time for re-starting the boiler may be varied by 2.5 min. All the regulations follow the
specific characteristics of the system where the boiler will be applied. It is necessary to check the inlet and outlet
pressures at the pressure plugs. After checking, tighten the bolts properly.

SWITCHING OFF
PROLONGED SWITCHING OFF
If the boiler should remain inactive at length close the gas cock and cut electrical power supply to the appliance.
TEMPORARY SWITCHING ON/OFF
Proceed in one of the following ways:
●use the room thermostat;
●use the adjustment potentiometers (on the instrument panel);
MAINTENANCE
NOTE: with a new boiler or after a long period of
inactivity, one can check for the locking of the
circulating pump. In this case it is necessary to
unscrew the front stopper and make the motor
shaft rotate with a screwdriver.
To ensure long-lasting product functionality and efficiency within the limits prescribed by the laws and standards
in force, the unit must undergo regular maintenance.
Frequency of inspection depends on the specific conditions of installation and use but it is advisable to have the
unit checked once a year by authorised Lamborghini Service personnel. Only properly qualified personnel
with specific knowledge in the field of safety, efficiency, environmental hygiene and combustion may carry out
work on the unit. To ensure proper maintenance it is also required that such personnel be fully updated on the
constructive and functional characteristics of the boiler.
Should work or maintenance be carried out on any structures situated near fume ducts and/or fume discharge
devices and their accessories always switch off the boiler and, when work is over, have its efficiency checked
by qualified personnel
IMPORTANT: before doing any cleaning or maintenance work on the unit switch off the electrical power supply
via the switch on the boiler itself. Shut off the gas supply by closing the tap on the boiler. The above stated,
work generally involves the following:
