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 WIN-
DOWS. SHUT OFF THE GAS COCKS.
INSTALL THE BOILER ON WALLS WHICH ARE AS WIDE AS OR WIDER THAN THE BOILER ITSELF.

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 N 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:
- a flue pipe concentric with the air intake pipe;
- a double pipe, one for flue gas exhaust and the other for combustion air intake.

ELECTRICAL CONNECTIONS - WIRING DIAGRAMS
The boiler must be connected to an earthed, single-phase 230V-50 Hz mains supply by means of a three-wire
cable, ensuring that connections to the PHASE and NEUTRAL terminals are made correctly.
A bipolar switch must be used with contacts opening to at least 3 mm.
The power lead must only be replaced by another with the following characteristics: “HAR H05 VV-F” 3 X 1.00
mm2. (You are strongly advised to use original LAMBORGHINI accessories and spare parts only).
Installation must be made in compliance with safety REGULATIONS IN FORCE.
Grounde connections are compulsory. Connect the boiler to an efficient grounding system.
To gain access to the electrical panel which houses the power supply terminal block and any connection to a
room thermostat, proceed as follows:
