Mason-Lite LMFP36-NT 36" Linear B-Vent Masonry Firebox Kit (No Trough)

LMFP36-NT Overview

The Mason-Lite LMFP36-NT is a 36 inch contemporary linear B-vent masonry firebox kit in the no-trough configuration. The flush-hearth design accepts a traditional H-burner gas log set or a Mason-Lite Virginiana log system, giving the installer flexibility on burner choice versus the trough version of the same size, which conceals a linear burner. Finished opening width is 36" with a 22-1/2" opening height, vented through 12" b-vent.

BTU output ranges up to 85,000 depending on the burner installed. The LMFP36-NT ships with high-temperature dry mortar; an angle iron / T-bar lintel is required and sourced locally per the install manual. Listed for indoor and outdoor installation, multi-story builds, and combustible-floor applications with appropriate non-combustible base. RADCO compliant for Class A and B-vent applications and ANSI Z21 compliant on B-vent.

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.
