Warranty - A.O. Smith BTL 100 Installation, User And Service Manual

12.6 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 one year 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
three 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;
• unfiltered, recirculated water flowing through
or being stored in the water heater;
• any attempts at repair to a defective water
heater other than by an approved service
engineer.
