WARRANTY 

 

The Manufacturer warrants to the original owner that the Product will be free of defects in material and workmanship. For the 
ITH-Series, warranty for all components is limited to twenty-four (24) months from the date of shipment. The hot rolled heat 
exchanger shall be warranted for an additional three (3) years for units which are proven to the satisfaction of the manufacturer 
to be inoperative due to defects in material or workmanship. 
 
Buyer’s sole and exclusive remedy for any nonconformity with this warranty shall be, at Manufacturer’s option, repair or 
replacement of nonconforming parts, provided that Buyer shall return to Manufacturer, shipping prepaid, said non-conforming 
part(s) bearing a durable tag indicating the Serial Number of the Product from which the part was taken. In addition, 
Manufacturer may opt not to repair or replace nonconforming Product or part(s), but instead may refund to Buyer the price 
thereof, in lieu of repair or replacement. In no event shall Manufacturer be liable for more than a refund of the purchase price 
or replacement value of the Product or part(s), whichever is less. This warranty does not cover any shipping, installation or 
other labor costs incurred in the repair or replacement of the product. No materials will be accepted for return without 
authorization. 
 
This Warranty does not apply and shall be void as to any Products that, in the judgment of the Manufacturer,  are misused or 
misapplied, that are installed, operated or maintained not in conformity with Manufacturer’s design, specifications, 
instructions, or Technical Manual, or are installed, operated or maintained in violation of any applicable national or local codes 
or industry standards. 
 
Manufacturer does not warrant Products, if they are abused, improperly operated or maintained, subjected to abnormal wear 
and tear, damaged due to improper gas or electric service, damaged in transit, or that have been repaired or modified by others 
without Manufacturer’s written authorization. This warranty will not apply to damage to the Product when used in corrosive 
atmospheres and in particular atmospheres containing halogenated hydrocarbons. No person is authorized to assume for the 
Manufacturer any other warranty, obligation or liability. 
 
Buyer shall have no right to enforce this Warranty unless it has complied with all of its obligations under the contract for 
purchase/lease of the Products, including without limitation, being current on all payment terms. 
 
THIS LIMITED WARRANTY IS MANUFACTURER’S ONLY WARRANTY WITH RESPECT TO THE PRODUCTS, 
AND IT IS IN LIEU OF AND SUPERSEDES ANY AND ALL OTHER WARRANTIES OF ANY KIND WHATSOEVER, 
WHETHER WRITTEN, ORAL OR IMPLIED, INCLUDING WITHOUT LIMITATION ANY IMPLIED WARRANTIES OF 
MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. THE REMEDIES AFFORDED BUYER BY THIS 
WARRANTY ARE THE ONLY REMEDIES AFFORDED BUYER FOR ANY NONCONFORMITY WITH THIS 
WARRANTY OR FOR ANY DEFECT IN PRODUCTS, SERVICES, OR REPRESENTATIONS PROVIDED BY 
MANUFACTURER IN CONNECTION WITH SUCH PRODUCTS. IN NO EVENT SHALL MANUFACTURER BEAR 
ANY LIABILITY FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND WHATSOEVER, 
INCLUDING WITHOUT LIMITATION PERSONAL INJURY (INCLUDING DEATH), PROPERTY DAMAGE, LOST 
PROFITS OR OTHER ECONOMIC LOSS. 
 
Buyer acknowledges that the foregoing warranty, limitations, and exclusions are a reasonable allocation of commercial risks by 
and among sophisticated business entities and are not subject to dispute as to their commercial reasonableness, fairness or 
ability to satisfy the essential purposes of the parties’ transaction.
