Lifetime  Limited Warranty

MASON-LITE FIREPLACE

Masonry Fireplaces Industries, Inc. (MFI) warrants all Mason-Lite Fireplaces to be free from defects in materials that adversely affect 

fireplace performance for the lifetime of the product from the date of purchase, subject to the terms and conditions of this limited warranty. 

MFI does not warrant accessory chimney, outside air ducts and devices not manufactured by MFI.

This warranty covers only products manufactured by MFI, specifically the modular concrete firebox, and 

NO WARRANTY, EXPRESS 

OR IMPLIED, EXTENDS TO ANY OF THE HARDWARE, FOUNDATION, VENTING, DUCTS, OR ACCESSORIES. THIS 

WARRANTY DOES NOT COVER DRAFTING, SMOKING, OR SOOTING OF THE FIREPLACE SYSTEM

.  Factors beyond the 

manufacturer’s control affect drafting, smoking, and sooting and MFI cannot guarantee these aspects of performance.

Coverage under this warranty is subject to the following conditions and exclusions:

• 

This warranty is null and void when the fireplaces are not installed pursuant to the installation instructions provided by MFI or local 

building codes have not been followed completely.

• 

Glass is warranted against thermal breakage only and only on models that are manufactured by MFI with a glass front. On Direct Vent 

models the safety glass or safety screen must be kept in front of this glass when fireplace is in use.                  Safety screen must be used 

on all models when in use.

• 

This warranty does not apply to any component or part that shows evidence of misuse, abuse, improper installation, accident or lack of 

regular maintenance.  MFI is not responsible for misuse or mishandling of component parts.

• 

This warranty does not apply to any damage sustained to the appliance while in transit.

• 

Neither MFI, nor any affiliate thereof, is responsible for any labor costs or indirect costs incurred for the replacement of defective 

components.  Any covered component that, in our judgment, is defective shall be repaired, replaced or refunded at MFI’s option.

• 

Nothing in this warranty makes MFI, or any affiliate thereof, liable in any respect for any injury or damage to the building or structure 

in which the fireplace has been installed or to the persons or property therein arising out of the use, misuse, or installation of properly 

manufactured MFI products.

• 

The fireplace must be used in accordance with operating instructions. The grate or andirons must be installed when using the fireplace. 

NEITHER MFI, NOR ANY AFFILIATE THEREOF, SHALL BE HELD LIABLE FOR ANY INCIDENTAL OR CONSEQUENTIAL 

DAMAGES OR EXPENSES ARISING OUT OF THE USE OF THE FIREPLACE. ALL SUCH DAMAGES AND EXPENSES ARE 

HEREBY EXCLUDED. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation 

or exclusion may not apply to you.

If a component is found to be defective under the terms of this warranty, the party this warranty is extended to shall notify MFI, 6391 

Jurupa Ave., PO Box 4338

, Riverside, CA 92514

 in writing, by registered mail, within thirty (30) days following the discovery of the 

defect within the lifetime warranty period. The letter shall include proof of purchase and state the (1) date of purchase, model number and 

serial number ; (2) place of purchase; (3) address of installation; (4) name, address and phone number of the homeowner; and (5) a brief 

description of the defect.

This warranty applies only to those fireplaces installed in the continental United States, Alaska and Canada. If any part of this warranty is 

found to be unenforceable, the remaining parts shall remain in force and effect.

THE FOREGOING WARRANTY IS EXCLUSIVE AND IS IN LIEU OF ALL OTHER WARRANTIES, TERMS OR CONDITIONS, 

EXPRESS OR IMPLIED EITHER IN FACT OR BY OPERATION OF LAW.  MFI HEREBY DISCLAIMS ALL GUARANTEES AND 

WARRANTIES, EXPRESS OR IMPLIED, BEYOND THE WARRANTIES SET FORTH HEREIN, INCLUDING BUT NOT LIMITED TO 

WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. Some states do not allow limitations on how 

long an implied warranty lasts, so the above limitation may not apply to you.
