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 pre-
pared to operate with the right
type of fuel, and carefully clean
the gas pipes to remove any re-
sidue that might hinder correct
operation. Make this connection
in accordance with the dimen-
sions and connections in sec-
tion 4.1.
1
Connect the corresponding gas inlet (see section 4.2)
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 TO THE UNIT AS POSSIBLE).
3
Once the connection to the gas network is complete,
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.
4
Check that the supplied pressure and gas delivery
values are those indicated for the unit's consumption.
See the technical data table
(section 4.5).
In installations with an appro-
ved flexible pipe for LPG, pay
special attention to the fol-
lowing.
•
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
Air and flue gas ducts
The diameter of the pipe connecting to the flue must not
be smaller than that of the pipe connecting to the draft
hood. After the draft hood, there must be a vertical seg-
ment at least half a meter long. The dimensions and in-
stallation of the flues and the tube connecting to them
must comply with current standards.
2.6.1 FUME EXHAUST SAFETY DEVICE (fume thermostat)
•
The water heater’s safety device ensures the correct
exhaust of flue gases;
THEREFORE DO NOT DEAC-
TIVATE IT OR CARRY OUT ANY OPERATION ON IT
.
•
If the safety device cuts in when the water heater is
started, check the flue gas outlet, checking the exhaust
with a cold mirror or with any suitable and approved
measuring device.
•
In case of a fault, only use original replacements,
otherwise the safety device may not work properly.
•
Fume thermostat replacement must be carried out by
qualified technicians, proceeding as follows:
- - Remove the faulty fume thermostat by undoing the
2 fixing screws.
- - Install a new original thermostat.
- - Fix the fume thermostat in its place without over-
tightening the screws.
- - Check its correct operation.
