4.

 

This new Mendota Fireplace must be installed & serviced by a competent, authorized service contractor.  It must be installed and oper-

ated at all times in accordance with the installation and operating instructions furnished with the Fireplace.  All adjustments to logs. 

Coals or burner must be made by an authorized Mendota person.   Any alteration, willful abuse, accident or misuse of the product shall 

nullify this warranty.  This warranty does not cover glass or log breakage. 

5.

 

This limited warranty does not cover the cost of service calls, the cost of labor to remove or install parts covered by this limited warran-

ty, freight or other transportation expenses, which may be incurred in connection with obtaining performances under this limited warran-

ty.  The remedy for damages as the result of any defects in this product which have been warranted herein is limited to replacement 

parts and does not include any incidental, indirect or consequential damages or expenses sustained in connection with the product, in-

cluding damages to property, except as provided by law.  

6.

 

This warranty is non-transferable and is made to the original retail purchaser, provided the purchase was made through an Authorized 

Mendota Dealer. 

7.

 

Mendota is not responsible for any damage to or malfunction of the Fireplace unless caused by a defect in material or workmanship 

from normal home use.  Damage caused by abuse, improper installation, improper servicing, and installation by unqualified personnel 

or breech of conditions of this limited warranty will excuse Mendota from performance of any part of this limited warranty.  Mendota 

has the right to investigate and inspect the exact, original Fireplace and entire installation (without any alterations or tampering) in the 

event a claim is made to determine whether the claimed damage or malfunction was caused by abuse, improper installation or other 

cause outside this warranty.  Mendota is not responsible for any repairs or material purchases that have not received prior written ap-

proval from Mendota. 

 

 

NOTE:  Minor warping of certain parts or discoloration is normal and is not a defect covered by this warranty.  Major warping of parts 

can be caused by over-firing of your Mendota Fireplace.  Over-firing above rated nameplate specification is as contrary to the manufac-

turer's instructions and may void this warranty. 

 

 

5.  This warranty may not be extended by our representatives or any third party in any manner. The company neither assumes, nor autho-

rizes any third party to assume, on its behalf, any other liabilities with respect to the sale of this Mendota product. 

6.  Mendota may at its discretion, fully discharge all obligations of this warranty by refunding the wholesale price of the defective part(s). 
7.  All other warranties - expressed or implied - with respect to the product, its components and accessories, or any obligation/liabilities on 

the part of the company are hereby expressly excluded.  Products made by other manufacturers, sold with the Fireplace or thereafter, 

are not covered by this limited warranty.  The use of unauthorized components will make this warranty null and void. 

 

3.  This warranty shall be effective only if the original purchaser of the Mendota appliance is registered with Mendota Division within thirty 

(30) days of the date of purchase.  Such registration or the failure to register shall not be deemed to create any obligation or liability by 

the manufacturer and this warranty with its conditions and limitations shall be the only procedure for obtaining any rights against the 

manufacturer and expresses the sole obligation and responsibilities of the manufacturer which are offered to the original purchaser and 

accepted upon purchase of the appliance. 

 

4.  Mendota Division, reserves the right to make changes at any time without notice, in design, material, specifications, prices and the right 

to discontinue styles and products. 

5.  Some states do not allow the exclusion of limitation of incidental or consequential damages or limitations on how long an implied war-

ranty lasts, 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.
