Mason-Lite MFP63 63" Pre-Cast Masonry Wood/Gas Firebox Kit

MFP63 Overview

The Mason-Lite MFP63 is the largest single-flue firebox in the standard Mason-Lite lineup. With a 60 inch finished opening width, a 30-1/2 inch finished opening height, and a 70-1/2 inch overall unit height, the 63 is built for great rooms, large primary suites, and outdoor patios where the firebox itself is the architectural anchor. Framing dimensions are 71 inches wide by 72-1/2 inches tall by 30 inches deep; floor area is 13.03 square feet.

The 63 vents through a 16 inch Class A UL103 chimney and requires the larger MFPB63 8 inch structural metal base for combustible-floor installs (versus the 6 inch base used on the 33 through 49). The PureBurn QWBN-63 / QWBP-63 EPA Phase II burner is sized specifically for the 63 and rated higher than the smaller-firebox QWBN-44 unit. Optional factory firebrick liner panels, the MFP-ARC63 masonry arch kit, and the MFP-SD63 steel throat damper or MFP-CC54 cast iron damper round out the most common accessory set.

Warranty

Masonry Fireplace Industries (MFI) provides a Limited Lifetime Warranty on Mason-Lite fireplaces. The warranty covers defects in materials of the modular concrete firebox that adversely affect fireplace performance, for the lifetime of the product from the date of purchase. Coverage applies only to fireplaces installed in the continental United States, Alaska, and Canada.

Specific terms include:

• Coverage is limited to the modular concrete firebox manufactured by MFI. Hardware, foundation, venting, ducts, chimney systems, outside air ducts, and accessories are not covered, even when supplied by MFI.
• Drafting, smoking, and sooting are excluded because they are influenced by site conditions outside the manufacturer's control.
• Glass is warranted against thermal breakage only and only on MFI-manufactured glass-front models. Safety glass or safety screen must be in place when the fireplace is in use.
• The warranty is void when the fireplace is not installed per the published installation instructions, or when there is evidence of misuse, abuse, improper installation, accident, or lack of regular maintenance.
• Damage in transit is not covered.
• Labor costs and indirect costs for component replacement are not covered. MFI may, at its option, repair, replace, or refund a defective covered component.
