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:
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 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.

Can I use either metal or masonry chimney on a Mason-lite fireplace?Yes, both are approved. |
Is the masonry chimney the same pumice material as the Mason-Lite fireplace?Yes |
Can I offset masonry chimney?Yes. Special offset parts are used, and every 5th offset must be supported. |
What is the 4” starter piece?This is used to off-set mortar joints- just another way Mason-Lite is looking out for your safety. |
Can I install a fireplace on the 2nd floor using masonry chimney?No. Metal chimney is required to keep the weight at a minimum. Wood or solid fuel burning units need to have clearances to wood under pinnings using a metal base or CMU block construction. Units on a wood floor must use metal chimney and cannot use a masonry chimney system. Please check with your structural engineer to make sure there is enough support for masonry fireplace. |
