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;
they must not have regulation devices (gate valves). If such devices are already in operation they must be
c)
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.
CHARACTERISTICS OF IN-BOILER WATER
Where water is hard and aggressive, LAMBORGHINI recommends that you install a proportional polyphosphate
dosager (DPO/B) so as to prevent deposits building up inside the boiler.
WATER TREATMENT IS ESSENTIAL IN THE FOLLOWING CASES:
A) Large-scale systems (with a high water content).
B) Frequent system water top-ups.
C) Hot water circuits.
Should it be necessary to partially or completely empty the system it should then be
refilled with treated water.
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.
