Mason-Lite MFP44 44" Pre-Cast Masonry Wood/Gas Firebox Kit

MFP44 Overview

The Mason-Lite MFP44 sits in the middle of the standard lineup with a 41 inch finished opening width and a 30-1/2 inch finished opening height. It is the most popular framing size in the family for new residential construction, balancing visual mass against the flue and structural requirements that come with a wider opening. Framing dimensions are 52 inches wide by 64-1/4 inches tall by 30 inches deep; floor area is 9.33 square feet.

The 44 vents through a 12 inch Class A UL103 chimney, the same flue as the 33 and 39, which keeps chase framing simple when comparing sizes. Optional factory firebrick panels install in under 20 minutes versus several hours for hand-laid firebrick. The 44 accepts the QWBN-44 / QWBP-44 PureBurn EPA Phase II burner (shared with the MFP49) and the optional QWB-EI electronic ignition module. For combustible-floor installs the MFPB44 6 inch structural base is required.

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.
