THIS WARRANTY IS APPLICABLE TO THE ORIGINAL OWNER ONLY.  If
the glass lined tank in this water heater shall prove upon examination by

water therein, the warrantor will furnish the ORIGINAL OWNER a
replacement A. O. Smith water heater of equivalent size and current model,
or a replacement part for any thermostat or thermocouple which fails in
normal use, in accordance with the warranty terms and conditions specified
below.  THE A. O. SMITH REPLACEMENT MODEL OR PART WILL BE
WARRANTED FOR ONLY THE UNEXPIRED PORTION OF THE ORIGINAL
WARRANTY.  The warranty period will be determined by the original
installation date of the water heater.  PROOF-OF-PURCHASE AND PROOF-
OF-INSTALLATION ARE NECESSARY TO VALIDATE THIS WARRANTY.
This warranty is not transferable and applies to models listed in Table 1.

When the water heater has been used for other than single family residential
application;   1.  The tank warranty shall be reduced to 1 year for 6 year
models and 3 years for 10 year models.   2.  The parts warranty shall be
reduced to 1 year for all models.  Returned parts which meet any of the
following conditions are not covered by this warranty: 1) improper
installation or removal, 2) damaged by other than normal wear, 3) replaced
for cosmetic purposes, or 4) returned with defaced date codes.

CONDITIONS AND EXCEPTIONS

This warranty shall apply only when the water heater is installed and
operated in accordance with 1) all local fire codes and plumbing codes,
ordinances and regulations, 2) the printed instructions provided with it, 3)
good industry practices, and 4) proper safety practices such as but not limited
to a properly sized drain pan if installed in an area where leakage from
connections of the tank would result in damage to the area adjacent to the
heater.  In addition, a new temperature and pressure relief valve, certified by
the American Gas Association must have been properly installed and piped
to the nearest drain.

This warranty shall apply only when the heater is:

owned by the original purchaser;

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

not subjected to excessive water pressure fluctuations and not subject to
an operating pressure greater than 150 P.S.I.;

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

used in a non-corrosive and non-contaminated atmosphere;

used with factory approved anode(s) installed;

in its original installation location;

in the United States, its territories or possessions, and Canada;

sized in accordance with proper sizing techniques for residential water
heaters;

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

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

fired at the factory rated input using the fuel stated on the face of the
rating plate;

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

maintained in accordance with the instructions printed in the manual
included with the heater.

Any accident to the water heater or any part thereof (including freezing, fire,
floods, or lightning), any misuse, abuse or alteration of it, any operation of it
in a modified form, or any attempt to repair tank leaks or parts will void this
warranty.

SERVICE AND LABOR RESPONSIBILITY

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, or reinstallation of the water heater or

part thereof.

b. Shipping and delivery charges for forwarding the new water heater or

replacement part from the nearest distributor and returning the claimed
defective heater or part to such distributor except in the state of
California where such charges are the manufacturer’s responsibility.

c. All cost necessary or incidental for handling and administrative charges,

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

LIMITATION ON IMPLIED WARRANTIES

Implied warranties, including any warranty of merchantability imposed on
the sale of this heater under state law are limited to one 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 limitations may not apply to you.

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.  If this is not
practical, the owner should contact: A. O. Smith Water Products Company, 500
Tennessee Waltz Parkway, Ashland City, TN 37015 (800) 323-2636.  Canadian
customers should contact A. O. Smith Enterprises, Ltd., P.O. Box 310-768 Erie
Street, Stratford, Ontario N5A 6T3, (519) 271-5800.

The warrantor will only honor replacement with identical or similar water
heater or parts thereof which are manufactured or distributed by the
warrantor.

Dealer replacements are made subject to in-warranty validation by
warrantor.

PROOF-OF-PURCHASE AND PROOF-OF-INSTALLATION DATE ARE
REQUIRED TO SUPPORT WARRANTY CLAIM FROM ORIGINAL OWNER.
THIS FORM DOES NOT CONSTITUTE PROOF-OF-PURCHASE OR
PROOF-OF-INSTALLATION.

DISCLAIMERS

NO EXPRESS WARRANTY HAS BEEN OR WILL BE MADE IN BEHALF OF
THE WARRANTOR WITH RESPECT TO THE MERCHANTABILITY OF
THE HEATER OR THE INSTALLATION,  OPERATION, REPAIR OR
REPLACEMENT OF THE HEATER OR PARTS.  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.

Some states do not allow the limitation or exclusion of incidental or
consequential damages, so the above limitation or exclusion may not apply
to you.

This warranty gives you specific legal rights, and you may also have other
rights which vary from state to state.
