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 TAPS.

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;

- “anti-Legionnaire’s” function

They are equipped with:

- Safety flow-switch;

-Total safety thermostat;

- High efficiency flue gas exchanger;

- 60-liter tank in stainless steel for plenty of hot water

- Electric 3-way valve

VELA X N 24 MB W TOP

Electronic ignition with ionisation flame control.
Combustion and fume discharge are of the atmospheric type. Fitted with FLUE CONTROL fume evacu­ation device.

FLUE CONTROL THERMOSTAT

VELA X N MB boilers are fitted with the FLUE CONTROL device to control evacuation of fumes. 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.

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 LINE 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.
Make a good earth connection.

To gain access to the electrical panel which houses the power supply terminal block and any connection to a
room thermostat, proceed as follows:
