If within one year of the original installation date of a storage water heater supplied by 
A.O. Smith, following verification, and at the sole discretion of A.O. Smith, an assembly 
or part (with exclusion of the tank) proves to be defective or fails to function correctly due 
to manufacturing and/or material defects, then A.O. Smith shall repair or replace this 
assembly or part. 
 
 
 
If within 5 years of the original installation date of a storage water heater supplied by 
A.O. Smith, following verification, and at the sole discretion of A.O. Smith, the glass-lined 
steel tank proves to be leaking due to rust or corrosion occurring on the water side, then 
A.O. Smith shall offer to replace the defective storage water heater with an entirely new 
storage water heater of equivalent size and quality. The warranty period given on the 
replacement storage water heater shall be equal to the remaining warranty period of the 
original storage water heater that was supplied. Notwithstanding that stated earlier in this 
article, in the event that unfiltered or softened water is used, or allowed to stand in the 
storage water heater, the warranty shall be reduced to one year from the original 
installation date. 
 
 
 
The warranty set out in articles 1 and 2 will apply solely under the following conditions: 
a.  The storage water heater is installed under strict adherence to A.O. Smith installation 

instructions for the specific model, and the relevant government and local authority 
installation and building codes, rules and regulations in force at the time of 
installation. 

b.  The storage water heater remains installed at the original site of installation. 
c.  The storage water heater is used exclusively with drinking water, which at all times 

can freely circulate (a separately installed heat exchanger is mandatory for heating 
saline water or corrosive water). 

d.  The tank is safeguarded against harmful scaling and lime build-up by means of 

periodic maintenance. 

e.  The water temperatures in the heater do not exceed the maximum setting. 
f.  The water pressure and/or heat load do not exceed the maximum values stated on 

the storage water heater plate. 

g.  The storage water heater is installed in a non-corrosive atmosphere or environment. 
h.  The storage water heater is connected to a protected cold supply arrangement, 

which is: approved by the relevant authority; with sufficient capacity for this purpose; 
supplying a pressure no greater than the working pressure stated on the storage 
water heater; and where applicable by a likewise approved temperature and pressure 
relief valve, fitted in accordance with installation instructions of A.O. Smith applying to 
the specific model of storage water heater, and further in compliance with the 
government and local authority installation and building codes, rules and regulations. 

i.  The storage water heater is at all times fitted with cathodic protection. If sacrificial 

anodes are used for this, these must be replaced and renewed when, and as soon 
as, they are 60% or more consumed. When power anodes are used, it is important to 
ensure that they continue to work properly.
