EXCLUSIONS AND LIMITATIONS: 
Limited Warranty and Tank Replacement Warranty are valid only if you comply 
with the following conditions and limitations: 
1.  The Alliance SL Water Heater is correctly installed according to the installation 
manual provided with the unit and all applicable local and national codes. 
2.  The unit is operated within the factory calibrated temperature limits and water 
pressure not exceeding 150 psi. 
3.  Any failure or malfunction that does not result from improper or negligent 
operation, accident, abuse (including freezing), misuse, unauthorized 
alteration or improper maintenance. 
4.  Any failure or malfunction that does not result from failure to keep the tank full of 
potable water, free to circulate at all times; and free of damaging water sediment 
or scale deposits. In areas where adverse water conditions are suspected (i.e. 
calcium and other minerals), it is essential that the water be tested and 
appropriate action be taken to prevent damage to the Alliance SL tank. It may be 
necessary to remove the heat exchanger for cleaning to maintain maximum 
performance in poor water areas. Diminished performance due to the build-up 
of calcium or other minerals, metals, or deposits on the heat exchanger is 
specifically not included in the coverage of these warranties. 
5.  THE FOREGOING EXPRESS LIMITED WARRANTIES ARE THE ONLY 
WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED. THERE ARE 
NO EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS 
FOR A PARTICULAR PURPOSE, PERFORMANCE OR NON-INFRINGEMENT, 
OR OTHER EXPRESS OR IMPLIED WARRANTIES. EXCEPT FOR THE 
LIMITED WARRANTIES SET FORTH HEREIN, THE COMPANY DISCLAIMS 
ALL OTHER WARRANTIES OR CONDITIONS, EXPRESS OR IMPLIED, 
REGARDING THE PRODUCT OR ITS OR THEIR FITNESS FOR A 
PARTICULAR PURPOSE OR ITS OR THEIR MERCHANTABILITY. 
PURCHASER SHALL HAVE SOLE RESPONSIBILITY FOR SELECTING 
APPROPRIATE WATER HEATER FOR THE PURCHASER'S NEEDS AND 
USE AND THE COMPANY DOES NOT WARRANT THE FITNESS FOR THE 
WATER HEATER'S INTENDED USE WITHIN ANY SPECIFIC SYSTEM. THE 
COMPANY DOES NOT AUTHORIZE COMPANY REPRESENTATIVES OR 
OTHER PERSONS TO VARY THE TERMS OF THE WARRANTIES HEREIN 
OR TO ASSUME FOR THE COMPANY ANY OTHER OBLIGATIONS OR 
LIABILITIES WITH RESPECT TO THIS PRODUCT. 
6.  The remedies set forth above shall be the sole and exclusive remedies for 
breach of any warranty. 
IN NO EVENT SHALL THE COMPANY BE LIABLE FOR ANY INCIDENTAL 
OR CONSEQUENTIAL DAMAGES WHATSOEVER. 
Consumer Notifications: The foregoing warranty limitations shall be effective 
to the maximum extent permitted by applicable law, and, to the extent that any 
such limitations would have an unconscionable result or would otherwise be 
inconsistent with applicable law, such provision shall be reformed to the extent 
necessary to avoid such unconscionable result or inconsistency. With respect to 
the limitations on implied warranties set forth above, the Company hereby 
notifies each person to whom such warranty is made as follows: Some states do 
not allow exclusions of such warranties, limitations on how long an implied 
warranty lasts or the exclusion or limitation of incidental or consequential 
damages, so the above limitations, or exclusions, may not apply to you. The 
limited warranty gives you specific legal rights, and you may also have other 
rights which vary from state to state.
