REPLACEMENT TANK - WARRANTY  RESIDENTIAL OR COMMERCIAL APPLICATION

 

For either a residential or commercial application, the following  applies to both when a replacement tank is provided for a tank found to be under warranty.

 

The replacement  tank warranty  assumes the remaining warranty period left from the original tank purchased.

 

WHAT  IS NOT COVERED BY EITHER OF THESE WARRANTIES

 

These warranties  are void  and shall not apply under the following circumstances:

 

1. The Techtanium™ water heater was not installed or repaired by a heating contractor whose principal occupation is the sale, installation and repair of

plumbing, heating and/or air conditioning  equipment.

 

2. These warranties  cannot  be considered  as a guarantee of workmanship of an installer connected with the installation of the Techtanium water heater, or

as imposing  on Diversified  Heat Transfer liability  of any nature for unsatisfactory performance as result of faulty workmanship in the installation or repair 

which liability  is expressly disclaimed.

 

3.  The failure or malfunction  results from improper  or negligent  operation, abuse, misuse or maintenance or unauthorized  alteration.
4. Malfunctions  resulting  from, or repairs necessitated by, uses of the indirect-fired  water heater for purposes other than  that for which  it was designed, or

resulting from flood, fire, wind, lightning, freezing or any other natural disaster or act of God, an act of destruction, theft or accident.

 

5.  The original  serial number  on the indirect-fired  water heater or component  thereof cannot be readily determined.
6.  Any indirect-fired  water heater is installed in a setting containing  any type of water softener system that is not installed and maintained  in accordance

with the manufacturer’s specifications.

 

7.  The Techtanium indirect-fired  water heater is used for non-potable  applications such as pool  or process heating.
8.  The failure or malfunction  results from failure to keep the tank full of potable water, free to circulate at all times and with the tank free of damaging water

sediment  or scale deposits.

 

9.  Components of an indirect-fired  water heater which are not defective, but  must  be replaced  during  the warranty  period  as a result of reasonable  wear

and tear.

 

10. Techtanium indirect-fired  water heaters which are repaired or altered without  prior written  approval  of Diversified  Heat Transfer so as to affect adversely

their reliability.

 

11. Diversified  Heat Transfer Techtanium™ indirect-fired  water heaters installed outside of the United States and Canada.
12. Service calls not involving  any malfunction  or defects and maintenance in the ordinary course.
13. Components of an indirect-fired  water heater which are not manufactured  expressly for Diversified  Heat Transfer; such components  are subject only to

those warranties, if any, given by their manufacturers. Diversified  Heat Transfer does not  adopt  and has no responsibility  for those warranties.

 

14. Any Techtanium tank that does not have installed a new temperature and pressure relief valve bearing the American Society of Mechanical Engineers

(A.S.M.E.) listing at the time of installation.

 

FURTHER LIMITATIONS  OF WARRANTIES AND REMEDIES

 

These warranties  give you specific legal rights, and you may also have other rights which vary from state to state. Some states do not allow the exclusion or 

limitation  of incidental or consequential damages, so this limitation  or exclusion may not apply to you.

 

These are the only written  warranties applicable to Diversified Heat Transfer Techtanium™ indirect-fired  water heaters manufactured for and sold by 

Diversified  Heat Transfer. Diversified  Heat Transfer neither  assumes nor  authorizes  anyone  to assume for it any other obligation or liability in connection with 

said Techtanium indirect-fired  water heaters.

 

This warranty  does not cover expenses or labor for disassembly, removal, shipment reassembly or reinstallation;  the original  purchaser will be 

responsible  for such costs.

 

Diversified  Heat Transfer’s performance under these warranties may be contingent  on shipment  of components or equipment  from suppliers. Diversified 

Heat Transfer shall not be liable for any failure or delay in delivery due to any cause beyond its control including without  limitation, strike, labor stoppage, a 

natural  disaster (such as earthquake, flood, fire or storm), political  insurrection or the unavailability  of components, equipment or supplies.
