When installed according to Metal-Fab Masonry Chimney Liner installation instructions, as prescribed by Underwriters Laboratories Standard 1777, Metal Fab Inc. warrants its aluminum chimney lining systems for two (2) years from the date of end-user installation. Metal-Fab warrants the Masonry Liner Kits to be free from defects in material and workmanship. During this period, Metal-Fab agrees to replace such defective components without charge. Liability under this warranty shall be limited to the replacement of the liner and accessories found to be defective and shall not include removal costs, re-installation costs, or any other costs.
This warranty shall continue for an additional thirteen (13) years on a pro-rated basis with the proration commencing with the original purchase date. It is the purchaser's responsibility to establish the date of the original installation of the product. Deviation from the installation and use instructions included with the liner will void the warranty. Since wood, coal, and oil can cause creosote, dirt, and debris to build up within a masonry chimney, the installer must be sure that the inside of the masonry chimney is properly cleaned before installing the aluminum liner. No chimney that is not structurally sound should be relined.
Since local or state building codes and fire officials may have installation restrictions, as well as inspection requirements, it is advisable that the installation and maintenance of chimney lining systems be performed by an experienced and certified professional. Important: Metal-Fab Aluminum Chimney Liners are to be used with natural gas or propane gas fuels only.
In order for this Limited Warranty to remain in effect: this liner system must not be exposed to chemically contaminated air; this product and the heating system to which it is connected must be inspected yearly by a qualified technician; a written record of inspections must be maintained by the end user; and system deficiencies must be remedied at time of discovery.
