INSTALLATION
5.1 Warnings
The unit must discharge the com-
bustion products directly outside
or in a suitable exhaust flue de-
signed for that purpose and in
compliance with current national
and local standards.
The unit is not suitable for receiv-
ing condensate from the combus-
tion product evacuation system.
Before installation, it is mandatory to thor-
oughly wash all of the system pipes with non-
aggressive chemical products. The purpose of
this procedure is to remove any residuals or
impurities that could jeopardise proper boiler
operation.
After washing, the system must be treated.
The conventional warranty does not cover any
problems resulting from the failure to follow
these instructions.
Check:
• That the boiler is suitable for the type of
gas distributed (check adhesive label).
If it is necessary to adapt the boiler to a dif-
ferent type of gas, see section "GAS CONVER-
SION" on page 58.
• That the characteristics of the electric, water
and gas supply networks comply with those
of the plate.
The combustion products may only be dis-
charged using the flue gas exhaust kits provid-
ed by the manufacturer, as they are an integral
part of the boiler.
For LPG gas (Butane G30 - Propane G31), the
installation must comply with the require-
ments of the distributing companies and com-
ply with the requirements of current technical
INSTALLATION
standards and laws.
The safety valve must be connected to a suit-
able discharge duct to avoid flooding if it is
activated.
The condensate discharge siphon must be
connected to the residential condensate dis-
charge duct and it must be possible to inspect
it and it must be implemented in a manner
to avoid the condensate from freezing (UNI
11071 and correlated standards).
The electric installation must comply with
technical standards, in particular:
• It is mandatory to connect the boiler to an
effective grounding system with a specific
terminal.
• A single pole switch must be installed near
the boiler to permit complete disconnection
in the conditions of over-voltage category III.
For the electrical connections refer to section
"Electrical connection" on page 40.
• The electric conductors for connecting
the remote control to the boiler must go
through different channels than those for
the mains voltage (230 V), as they are sup-
plied with low safety voltage.
5.2 Precautions for installation
• Mount the boiler on a resistant wall
• Respect the measurements of the flue gas
evacuation duct (provided in section "Flue
gas discharge dimensions and lengths" on
page 35) and the correct systems for in-
stalling the duct shown in the instruction
sheet provided together with the flue gas
evacuation pipe kit.
• Leave the minimum distances indicated in-
Figure 5.1 around the unit.
Follow these directions for instal-
lation:
