4. WARRANTY
4.1 General Warranty
If, within one year from the original
installation date, after investigation and
exclusive evaluation by A.O. Smith, a
boiler delivered by A.O. Smith turns out
to have a part, with the exception of the
tank, that is not properly functioning as a
result of manufacturing or material faults,
A.O. Smith will replace or repair this part.
4.2 Tank Warranty
If, within 3 years of the original
installation date, after investigation and
exclusive evaluation by A.O. Smith, a
boiler delivered by A.O. Smith turns out
to have a steel glass-lined tank that is
leaking as a result of rust or corrosion
from the water side, A.O. Smith 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 or softened water is
flowing through the boiler or left in it.

national installation and building
regulations, instructions and rules;
b) that the boiler will remain installed in

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 have 60 %
