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 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

XILO T 24 M W TOP
Electronic ignition and ionization flame control.
Combustion and flue gas exhaust are of atmospheric type. It is equipped with flue gas exhaust control device
(FLUE CONTROL).
FLUE CONTROL THERMOSTAT
The XILO T 24 M 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 instruc-
tions 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 24 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.

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).
START UP
REFILLING INSTALLATION
Open the supply tap slowly until the pressure of the installation, indicated by the hydrometer, is raised to the
value of 1.5 bar, then close it again. Verify that the automatic air bleed valve on the circulator has its cap
loosened. Operate the circulating pump repeatedly to release any air remaining in the circuit.
SWITCHING ON
Open the gas tap and turn the selector to the desired position. The burner will ignite automatically. Should the
burner fail to ignite check if the lock-out warning light is on and, if so, turn the selector to the RESET position so
that the boiler repeats the ignition sequence.
After that, adjust both heating and hot water temperature to the desired levels by acting on the appropriate
selectors.

45
CONNECTION TO THE CHIMNEY - VERSION XILO T 24 M W TOP
The boiler is envisaged being connected to a chimney and/or a flue pipe; it can also discharge combustion
products directly outside.
The connection to the chimney or to the flue must be made with a flue pipe with the following specification:
●of being sealed airtight, as with the connection to the chimney itself;
●of being of suitable material;
●of being connected within sight;
●not having more than three directional changes, not being more than 3, and be made with internal
angles higher than 90°and utilizing bends;
●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.

CONNECTION TO THE CHIMNEY - VERSION XILO T 24 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 pipe system;
●fume evacuation/air intake double pipe 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 on page 46.
For positioning and for distances of draught terminals from windows, doors, etc. see regulations in force.

GAS PRESSURE ADJUSTMENTS WITH HONEYWELL VK 4105 VALVE
All boilers are tested and calibrated in the factory. At first ignition it is necessary to check and set up the boiler
to adapt it to the system characteristics. The gas pressure at the burner must be checked through the pressure
plug placed on the pipe coming out from the gas valve and by using a water column pressure gauge or a
micro-manometer. The values must be those indicated in the specific table. When all calibrations have been
completed, close and seal the pressure plug used. Calibration of the slow ignition 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 acting on the trimmer R.MAX. By remov-
ing the JP4 bridge, the waiting time for boiler restarting can be varied, after its stop when reaching the
temperature selected on the heating potentiometer. (bridge off: 2,5 minutes)
MODULATION MAXIMUM PRESSURE ADJUSTMENT
●remove the protecting cover G
●place the “function selector” on TEST position
●tighten (to increase) or untighten (to decrease) the adjustment bolt H
MINIMUM PRESSURE ADJUSTMENT
After the maximum pressure adjustment has been completed proceed with the following operations:
●disconnect the power wire (12 V) from the modulation coil
●tighten (to increase) or untighten (to decrease) the adjustment bolt I
●connect again the modulation coil power wire (12 V) (“function selector” must always be on TEST position)
●replace the protecting cover G

MAINTENANCE
Note: With a new boiler or after a long period of
inactivity, the locking of the circulating pump can
occur. 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 stand-
ards 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 and via the system main switch. Then shut off the gas supply by closing the tap
on the boiler. The above stated, work generally involves the following:
-rimozione delle eventuali ossidazioni dai bruciatori;
-rimozione delle eventuali incrostazioni degli scambiatori;
