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 first 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 efficient 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 efficient 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, ordinances and regulations, the printed instructions provided with it and good industry practices. In addition, a temperature and pressure relief valve, certified by and officially 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)filled 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 dirt leg;

(12)fired with the fuel for which it was factory built;

(13)fired 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 modified form, or any attempt to repair tank leaks will void this warranty.

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

4.SERVICE AND REPAIR EXPENSES

Under the limited warranty the warrantor will provide only a replacement water heater or part thereof. The owner is responsible for all other costs. Such costs may include but are not limited to:

a.Labor charges for service removal, repair or reinstallation of the water heater or any component part;

b.Shipping, delivery, handling, and administrative charges for forwarding the new heater or replacement part from the nearest distributor and returning the claimed defective heater or part to such distributor.

c.All cost necessary or incidental for any material and/or permits required for installation of the replacement heater or part.

5.LIMITATIONS ON IMPLIED WARRANTIES

Implied warranties, including the warranty of merchantability imposed on the sale of this heater under state law or local code are limited to one (1) year duration for the heater or any of its parts. Some areas do not allow limitation on how long an implied warranty lasts, so the above limitation may not apply to you.

6.CLAIM PROCEDURE

Any claim under the warranty should be initiated with the dealer who sold the heater, or with any other dealer handling the warrantor’s products. If this is not practicable, the owner should contact:

THE WARRANTOR SHALL NOT BE RESPONSIBLE FOR WATER DAMAGE, LOSS OF USE OF THE UNIT, INCONVENIENCE, LOSS OR DAMAGE TO PERSONAL PROPERTY OR OTHER CONSEQUENTIAL DAMAGE. THE WARRANTOR SHALL NOT BE LIABLE BY VIRTUE OF THIS WARRANTY OR OTHERWISE FOR DAMAGE TO ANY PERSONS OR PROPERTY, WHETHER DIRECT OR INDIRECT, AND WHETHER ARISING IN CONTRACT OR IN TORT.
