Mason-Lite MFP33 33" Pre-Cast Masonry Wood/Gas Firebox Kit

MFP33 Overview

The Mason-Lite MFP33 is the most compact firebox in the Mason-Lite modular masonry lineup. With a 30 inch finished opening width and a 22-1/2 inch finished opening height, the 33 fits applications where wall space is at a premium but the homeowner still wants the look and feel of a true masonry fireplace. The full kit ships with high-temperature dry mortar, the steel T-bar lintel, and rebar (rebar is required only in seismic zones 3 and 4 but ships standard nationwide). Field assembly takes a trained installer two to three hours.

The MFP33 is approved for indoor and outdoor installation, multi-story and combustible-floor builds (with the MFPB33 6 inch metal base), and either wood burning or vented gas log applications per ANSI Z21.60. It vents through a 12 inch Class A UL103 chimney system, with a maximum installed system height of 40 feet. For builders pursuing EPA Phase II compliance, the optional PureBurn natural gas or propane burner with electronic ignition turns the MFP33 into a dual-fuel clean-burning unit.

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.
• Claims must be submitted to MFI in writing by registered mail within 30 days of discovering the defect, including the date of purchase, model and serial number, place of purchase, address of installation, homeowner contact information, and a description of the defect.
