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
watertherein, 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:
(1) at temperatures not exceeding the maximum setting of its thermostat;
(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;
(4) in a noncorrosive and non-contaminated atmosphere;
(5) in the United States, its territories or possessions, and Canada.
(6) used with factory approved anode(s) installed;
(7) in its original installation location;
(8) sized in accordance with proper sizing techniques for commercial water heaters;
(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.
