If the water hardness is over 25ºFr (1ºF=10ppm
CaCO3), the water must be treated to avoid
possible deposits on the unit.

2.5 Gas connection

Before making the connection,
check that the unit has been
prepared to operate with the
right type of fuel, and carefully
clean the gas pipes to remove
any residue that might hinder
correct operation. Make this
connection in accordance with
the dimensions and connec-
tions in section 4.1.
1 Connect the corresponding gas inlet (see section 4.1)
in accordance with current regulations in the country
where the heater is being installed.
2 Connect using a rigid metal pipe (connection to
a gas supply network) or a flexible, continuous
stainless steel pipe (LPG installation), adding a
shut-off valve between the installation and the unit
(AS CLOSE AS POSSIBLE TO THE UNIT).
3 Once the connection to the gas network is comple-
te, check that all gas connections are tight. For this
purpose, a tightness test must be performed. To avoid
damage to the unit due to excess pressure, leave the
gas inlet valve closed.
Check that the supplied pressure and gas delivery va-
lues are those indicated for the unit's consumption. See
the technical data table (section 4.4).
In installations with an approved
flexible pipe for LPG, pay spe-
cial attention to the following:
• The pipe must comply with applicable regulations.
• Avoid areas with heat emissions.
• Prevent the pipe from bending or being pinched shut.
• The connections on both sides (gas valve and other
components) must comply with the regulations of the
country where the heater is installed.

2.6 Electrical connections

The unit's electrical safety is
only ensured when it's effecti-
vely grounded, as established
by safety standards. Have qua-
lified personnel check the effec-
tiveness and suitability of the
grounding system, as the ma-
nufacturer will not be liable for
any damage caused by a lack of
grounding on the installation.
The unit's power cable may not be replaced by the user.
If the cable is damaged, turn off the unit and call the
authorized technical support center to have it replaced.
To replace the cable, use only the 3x0.75mm
VV-F cable, with a maximum outer diameter of 8 mm.
