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.
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 57.
• That the characteristics of the electric, water
and gas supply networks comply with those
of the plate.
The minimum heating system return tempera-
ture must never be lower than 40 °C.
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, the installation must comply with
the requirements of the distributing compa-
nies and comply with the requirements of cur-
rent technical standards and laws.
The safety valve must be connected to a suit-

able discharge duct to avoid flooding if it is
activated.
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 overvoltage category III.
For the electrical connections refer to section
"Electrical connection" on page 41.
• 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 supplied
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.
