sw-37 thru sw-670 electrIc hot water BoIler lIMIted warranty

State Water Heaters, the warrantor, extends the following LIMITED WARRANTY to the owner of this boiler.

1. 

THE TANK

  If the tank in this boiler shall prove upon examination by the warrantor to have leaked due to natural corrosion from water therein, during the FIRST 

year after initial installation, the warrantor will at its option, repair it or provide a replacement tank less elements and controls of equivalent size and 

then current model. Some government agencies are requiring energy efficient standards for boilers. In the event regulations prohibit sale of a model 

of equivalent size and construction, State Water Heaters 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 repair or 

replacement of the part, portion or tank will be limited to the unexpired term of the original warranty.

2. ALL OTHER PARTS

  If within ONE year after initial installation of this boiler, 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 EXPECTATIONS

  This warranty shall apply only when the boiler 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 pressure relief valve, approved by the American Society of 

Mechanical Engineers, must have been installed.

  This warranty shall apply only when the boiler is used:

  a. (1)  at temperatures not exceeding the maximum setting of its control;

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

    (3)  when filled with water, free to circulate at all times and with the tank free of damaging scale deposits;

    (4)  in a noncorrosive and non-contaminated atmosphere;

    (5)  in its original installation location;

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

    (7)  when operated free of the damaging effects of uncontrolled thermal expansion and/or water hammer.

  b. Any accident to the boiler, any misuse, abuse (including freezing) or alteration of it, any operation of it in a modified form will void this warranty.

4. SERVICE AND REPAIR EXPENSE

  Under this limited warranty the warrantor will provide only repair or a replacement tank 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 tank or any component part;

  b. Shipping,  delivery,  handling,  and  administrative  charges  for  forwarding  the  new  tank  or  replacement  part  from  the  nearest  distributor  and 

returning the claimed defective tank or part to such distributor.

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

5. LIMITATION ON IMPLIED WARRANTIES

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

the tank 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 boiler, or with any other dealer handling the warrantor’s products.  If 

this is not practicable, the owner should contact:
