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 A.G.A.and 

approved by the American Society of Mechanical Engineers, must have been installed.

 

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

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

 

 

(3) when filled with potable water, free to circulate at all times;

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

 

 

(10) not used in a closed system without a properly sized and installed thermal expansion tank;

 

 

(11) fired at the proper voltage and wattage;

 

 

(12) maintained in accordance with the instructions printed in the manual included with the heater.

 

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

 

 

 

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

4.  SERVICE and REPAIR EXPENSE

 

Under this 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 materials and/or permits required for installation of the replacement heater or part.

5.  LIMITATIONS ON IMPLIED WARRANTIES

 

Implied warranties, including any warranty of merchantability imposed on the sale of this heater under state law are limited to one (1) year duration for the 

heater or any of its parts. Some states do not allow limitations on how long an implied warranty lasts, so the above limitation may not apply to you.

6.  CLAIM PROCEDURE

 

Any claim under this warranty should be initiated with the dealer who sold the heater, or with any other dealer handling the warrantor’s products.
