13.6 Warranty
To register your water heater, you can complete and return the enclosed warranty card.
You can also register your water heater on-line through the A.O. Smith website.
Article 1: General warranty
If, after verification and at the sole discretion of A.O. Smith, a component or part (with
exclusion of the glass lined steel tank) of a water heater supplied by A.O. Smith proves
within two years of the original installation date to be defective or fails to function correctly
due to manufacturing and/or material defects, then A.O. Smith shall repair or replace this
component or part.
Article 2: Tank warranty
If, after inspection and at the sole discretion of A.O. Smith, the glass-lined steel tank of a
water heater supplied by A.O. Smith proves within 3 years of the original installation date
to be leaking due to rust or corrosion occurring on the water side, then A.O. Smith shall
offer to replace the defective water heater with an entirely new water heater of equivalent
size and quality. The warranty period given on the replacement water heater shall be equal
to the remaining warranty period of the original 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 water heater, the warranty shall be reduced to
one year from the original installation date.
Article 3: Conditions for Installation and Use
The warranty set out in Articles 1 and 2 will apply solely under the following conditions:
• The 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.
• The water heater remains installed at the original site of installation.
• The 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).
• The tank is safeguarded against harmful scaling and lime build-up by means of
periodic maintenance.
• The water temperatures in the heater do not exceed the maximum setting of the
thermostats, which form a part of the water heater.
• The water pressure and/or heat load do not exceed the maximum values stated on
the water heater rating plate.
• The water heater is installed in a non-corrosive atmosphere or environment.
• The water heater is connected to a protected cold water supply arrangement, which
is approved by the relevant authority; with sufficient capacity for this purpose;
supplying a water pressure not greater than the working pressure stated on the
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 water heater, and further in compliance with the government
and local authority installation and building codes, rules and regulations.
• The 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.
Article 4: Exclusions
The warranty set out in Articles 1 and 2 will not apply in the event of:
• damage to the water heater caused by an external factor;
• misuse, neglect (including frost damage), modification, incorrect and/or unauthorised
use of the water heater and any attempt to repair leaks;
• contaminants or other substances having been allowed to enter the tank;
• the conductivity of the water being less than 125 μS/cm and/or the hardness
(alkaline earth ions) of the water being less than 1.00 mmol/litre (see 8.2.3);
