Whenever requested, it must be proved by submitting the technical report of the
entity responsible for it, or alternatively by registering them in the instruction manual
in the dedicated section.

In order to avoid damage to the equipment caused by overpressure, safety
elements such as pressure relief valves and / or thermal discharge valves, if
applicable, as well as an expansion vessel fitted to the installation, shall be ensured at
the time of installation and its correct functioning must be ensured. It should be noted
that: the valves referenced must have a value equal to or less than the pressure
supported by the equipment; there shall be no cut-off valve between the equipment
and its safety valve; provision should be made for a systematic preventive
maintenance plan to attest to the correct functioning of the said safety features;
irrespective of the type of appliance, all safety valves shall be channelled to drained
sewage to prevent damage to the dwelling by water discharges. Product Warranty
does not include damages caused by non-channelling of water discharged by said
valve.
3.13
In order to avoid damage to the equipment and attached pipes by galvanic
corrosion, it is advisable to use dielectric separators in the connection of the
equipment to metal pipes whose characteristics of the materials applied to this type of
corrosion. Product Warranty does not include damages caused by non-use of such
dielectric separators.
3.14
The water or thermofluid used in the heating system (hydro stoves, boilers,
central heating stoves, among others) must comply with the legal requirements in
force, as well as guarantee the following physical and chemical characteristics:
absence of solid particles in suspension; low level of conductivity; residual hardness of
5 to 7 degrees; neutral pH, close to 7; low concentration of chlorides and iron; and
absence of air inlets by depression or others. In case the installation enhances
automatic water make-up, it should consider upstream a preventive treatment system
composed of filtration, decalcification and preventive dosing of polyphosphates (scale
and corrosion), as well as a degassing step, if necessary. If in any circumstance any of
these indicators show values that are not recommended, the Warranty will cease to
have effect. It is also compulsory to place a non-return valve between the automatic
filling valve and the mains water supply, and that said supply always has constant
pressure, even with a lack of electricity, not depending on lift pumps, autoclaves, or
