2 INSTALLATION INSTRUCTIONS
2�1 General instructions
The installation must only be performed by an authorized installation technician, as must
the electrical, gas and fumes/air exhaust/intake connections respectively, complying with
all instructions provided in this manual, the EN 26 standard, as well as the local regula-
tions for installing and venting combustion products.
2�2 Installation location
• The combustion circuit is sealed off from the installation envi-
ronment, so the unit can be installed in any room. However,
the room must be sufficiently ventilated to prevent dangerous
situations if there is a gas leak.
• REGULATION (EU) 2016/426 stipulates the safety standards
for all installations that work with gas, including those with a
sealed chamber.
• The unit can operate in a location partially protected in accor-
dance with the EN 26 standard.
In any case, the unit must be installed in a location free of dust,
flammable objects or materials, or corrosive gases.
The unit can be installed on the wall:
• Attach to the wall according to the dimensions shown in
Section 4.1. The wall installation must be firm and stable.
• Do not install the unit over a heat source.
If the unit is installed inside a closet, for exam-
ple, or if it connects laterally to other elements, a space
must be left to remove the unit's casing and to perform
regular maintenance work.
