limited warranty

Limited Warranty

A. O. Smith Corporation, the warrantor, extends the following LIMITED WARRANTY to the owner of this water heater.
1. 

THE TANK

 

If the glass-lined tank in this water heater shall prove upon examination by the warrantor to have leaked due to natural corrosion from potable water 

therein, during the 

 THREE years after initial installation, the warrantor will supply a complete new A. O. Smith water heater of equivalent size and 

current model.  Some government agencies are requiring energy 

 standards for water heaters.  In the event regulations prohibit sale of a model 

of equivalent size and construction, A. O. Smith will provide a model which complies with the regulations of your area, in which case the consumer 

will be charged the difference in price between the like replacement and the energy 

 model required.  The warranty on the replacement water 

heater will be limited to the unexpired term of the original warranty.

2. 

ALL OTHER PARTS

 

If within ONE year after initial installation of this water heater, any part or portion shall prove upon examination by the warrantor to be defective in 

material or workmanship, the warrantor will repair or replace such part or portion at its option.

3. 

CONDITIONS AND EXCEPTIONS

 

This warranty shall apply only when the water heater is installed in accordance with local plumbing and building codes, ordina nces and regulations, 

the printed instructions provided with it and good industry practices.  In addition, a temperature and pressure relief valve, 

 by and 

 

sanctioned and recognized independent testing agency and approved by the American Society of Mechanical Engineers, must have been installed.

 

a.        This warranty shall apply only when the heater is:

   (1)  used at temperatures not exceeding the maximum calibrated setting of its thermostat;

   (2)   used at water pressure not exceeding the working pressure shown on the heater;

   (3) 

 with potable water, free to circulate at all times and with the tank free of damaging water sediment or scale deposits;

   (4)   used in a non-corrosive and non-contaminated atmosphere;

   (5)   used with factory approved anode(s) installed;

   (6)   in its original installation location;

   (7)   in the United States, its territories or possessions or Canada;

   (8)   sized in accordance with proper sizing techniques for commercial and/or residential water heaters;

   (9)   bearing a rating plate which has not been altered, defaced or removed, except as required by the warrantor;

   (10)   used in an open system or in a closed system with properly sized and installed thermal expansion tank;

   (11)   operated with properly installed sediment trap;

   (12) 

 with the fuel for which it was factory built;

   (13) 

 at the factory rated input;

   (14)   operated with the inner and outer combustion chamber doors in place.

 

b.  Any accident to the water heater, any misuse, abuse (including freezing or thermal expansion damage) or alteration of, any operation in a  

 form, or any attempt to repair tank leaks will void this warranty.

 

c.  This warranty is void if a device acting as a 

 prevention device (check valves etc.) is installed in the cold water supply the heater is con-

nected to, unless an effective method of controlling thermal expansion is also installed at the heater(s) and operational at all times.  The relief 

valve installed on the heater is not an acceptable method.
