4. WARRANTY

(CERTIFICATE)

In order to register your warranty,
please fill in the enclosed warranty
card and return it to us. We will then
send you a warranty certificate.

This certificate will provide the owner
with a warranty as described below
for a boiler delivered by STATE WATER
HEATERS, who will be committed to
provide the owner with this warranty.

4.1

Warranty general

If, within one year of the original
installation date, after investigation and
exclusive evaluation by STATE WATER
HEATERS, a boiler delivered by STATE
WATER HEATERS turns out to have a
part, with the exception of the tank, not
function as it should as a result of
manufacturing or material faults,
STATE WATER HEATERS will replace
or repair this part.

4.2

Warranty tank

If, within five years of the original
installation date, after investigation and
exclusive evaluation by STATE WATER
HEATERS, a boiler delivered by STATE
WATER HEATERS turns out to have a
steel glass-lined tank that is leaking as
a result of rust or corrosion from the
water side, STATE WATER HEATERS
will replace the whole boiler by a
completely new one of similar size and
quality. The replacement boiler will
have a warranty that will be valid for
the remaining period of the warranty
for the original boiler delivered.

Notwithstanding the provisions in
Article 2, the warranty term will be
reduced to one year after the original
installation date if unfiltered, softened
water is flowing through the boiler or
left in it.

4.3

Conditions of installation
and use

The warranty referred to in Articles 1
and 2 only apply if the following
conditions are met:
a) that the boiler is installed according

to the installation instructions of
STATE WATER HEATERS for the
specific model, as well as
according to the local and national
installation and building regulations,
instructions and rules;

b) that the boiler will remain installed in

the original installation position;

c ) that only drinking water is used,

which is allowed to circulate freely
at all times (a separately installed
heat exchanger is requisite for the
heating of saline or corrosive
water);

d) that the tank has been defurred to

remove harmful scale deposits by
means of periodic maintenance;

e) that the boiler-water temperatures

do not exceed the maximum settings
of the thermostats that are part of
the boiler;

f ) that the water pressure and/or heat

load do not exceed the maximum
values indicated on the boiler’s
identification plate;

g) that the boiler has not been installed

in a corrosive atmosphere or
environment;

h) that the boiler has been provided

with an inlet combination, approved
by an authorised body, of sufficient
capacity, not greater than the
operating pressure indicated on the
boiler, and, if applicable, with a
temperature and pressure relief
valve, also approved by an
authorised body, which has been
mounted according to the installation
instructions of STATE WATER
HEATERS that apply to the specific
boiler model, as well as according
to the local and national instructions,
regulations and rules;

i) that the anodes are replaced and

renewed if and when they are
worn for 60% or more.
