GENERAL INSTRUCTIONS
●This booklet constitutes an integral and essential part of the product.
Read carefully the instructions contained in this booklet as they provide important directions regarding the
safety of installation, use and maintenance. Preserve this booklet with care for any further consultation.
The installation of the boiler must be carried out in compliance with current regulations, according to the
instructions of the manufacturer and by qualified personnel. An incorrect installation can cause injury or
damage to persons, animals and objects, for which the manufacturer cannot be held responsible.
●After removing the packaging materials, check the content integrity. In case of doubt, do not use the unit
and contact the supplier. The packaging material (wooden crates, nails, clips, plastic bags, foam, etc.)
must not be left within reach of children as they are potential sources of danger.
●This boiler is designed to heat water to a temperature below boiling (atmospheric pressure). It must be
connected to a heating system compatible with its performances and output.
●This appliance should be destined only for the use for which it has been expressly envisaged. Any other
use is to be considered improper and therefore dangerous. The manufacturer cannot be considered
responsible for any damages caused from improper, erroneous or unreasonable use.
ALL INSTALLATION, MAINTENANCE AND GAS CONVERSION OPERATIONS MUST BE CARRIED OUT BY
AUTHORISED SKILLED TECHNICIANS.
TO ENSURE THAT BOILER IS INSTALLED CORRECTLY AND THAT IT FUNCTIONS PROPERLY, WE RECOMMEND
THAT ONLY LAMBORGHINI ACCESSORIES AND SPARE PARTS BE USED.
ON NOTICING THE SMELL OF GAS DO NOT TOUCH ANY ELECTRIC SWITCH. OPEN DOORS AND WINDOWS.
SHUT OFF THE GAS COCKS.
INSTALL THE BOILER ON WALLS WHICH ARE AS WIDE AS OR WIDER THAN THE BOILER ITSELF.

32
DESCRIPTION
These boilers are fully automatic and gas control is effected by an electronic control unit having the following
characteristics:
-continuous modulation mode on both circuits;
-possibility to adjust the heating output;
-possibility to adjust the slow ignition;
XILO T models are equipped with:
-no-water pressure switch;
-total safety thermostat;
-high efficiency bi-thermal flue gas exchanger;
-Hot water plate exchanger.
XILO T 20 M W TOP
Electronic ignition with ionization flame control.
Atmospheric-type combustion and flue gas exhaust. A special FLUE CONTROL device for flue gas exhaust is
also supplied.
FLUE CONTROL THERMOSTAT
The boiler is fitted with the FLUE CONTROL thermostat for control of fume evacuation. An increase in
fume temperature in the down-draught diverter indicates an anomaly in fume evacuation. The FLUE
CONTROL probe in the down-draught diverter detects variations in temperature and shuts down the
boiler. Efficient operation of this safety system depends on observance of the following:
-Do not deactivate the FLUE CONTROL thermostat.
-Inspect the boiler and the flue immediately if the FLUE CONTROL device trips frequently.
-If the FLUE CONTROL device is changed make sure you observe assembly and probe positioning
instructions carefully and use only original LAMBORGHINI spare parts.
If there is a fume evacuation anomaly act quickly to prevent the formation of Carbon Monoxide, a
poisonous gas that causes intoxication and potentially fatal harm to both humans and animals.
XILO T 20 MS W TOP
Equipped with electronic control unit for automatic ignition and ionization electrode flame control.
To ensure safe operation, the electric fan is controlled by a pressure switch.
Flue gas exhaust can be made by means of the following:
-aflue pipe concentric with the air intake pipe;
-adouble pipe, one for flue gas exhaust and the other for combustion air intake.

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.

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 G20 (Natural Gas) and G30/G31 (LPG), 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

CONNECTION TO THE CHIMNEY - VERSION XILO T 20 M W TOP
The boiler is envisaged being connected to a chimney and/or a flue pipe; the combustion fumes can also be
discharged directly outside.
The joining to the chimney or flue pipe must be made with a smoke conduit having the following features:
●of being sealed airtight, as with the connection to the chimney itself;
●of being of suitable material;
●of being connected within sight;
●of having changes in direction, not more than 3 no., which must be carried out with internal angles greater
than 90°and with the use of curved elements;
●of not having any intercepting devices;
●of having the axis at the entrance of the terminal section perpendicular to the opposite internal wall of the
chimney;
●of being firmly fixed and sealed at the entrance, without protruding beyond the inner walls of the chimney;
●of receiving preferably one boiler only;
●of observing the local regulations in force.
WARNING:
This unit is fitted with a Flue Control device to control flue draught. This device is tripped when there is a risk of
combustion fume backflow. This device must never be deactivated. If combustion fumes re-enter the room they
may cause chronic or acute intoxication and can be fatal. If the Flue Control device is changed use only
original spare parts. If the device trips repeatedly check for proper fume outflow via the chimney flue and
contact a Lamborghini Service Centre.
