Monessen Lo-Rider 36 Inch LCUF Clean Face Vent Free Gas Firebox with Panels
The Monessen Lo-Rider Series offers a sleek, low-profile hearth that mimics the look of a traditional wood-burning fireplace, featuring a tall, expansive opening and impressive viewing area. Designed to be installed without a chimney, flue, or vent, this vent-free firebox is ideal for spaces where a conventional fireplace would be too difficult or expensive to install. It connects easily to a gas line, making it a cost-effective solution that doesn’t compromise on style or performance. The Lo-Rider’s flush hearth design and its wide, tall opening offer the charm of a classic fireplace, and with options like Monessen vent-free log sets, hide-away screen pockets, and a variety of interior panels and add-ons, you can customize it to fit your room perfectly.
This firebox is part of the LCUF series, which comes in three sizes—32″, 36″, and 42″—with a choice of interior panels including Cement Grey Stacked Traditional, Multi-Tonal Brown Traditional, Multi-Tonal Grey Stacked Traditional, and Multi-Tonal Grey Herringbone. It can be installed in a wall or free-standing cabinet, offering flexibility and a simple, budget-friendly installation. Because it doesn’t require a chimney or vent, the Lo-Rider Series is perfect for spaces where installing a traditional fireplace would be impractical or too costly. Its zero-clearance installation allows it to be placed flush against combustible materials, saving on installation costs and expanding placement possibilities.
The Lo-Rider firebox also focuses on maximizing heat output, using unique air channels to move more warmth into the room. With features like an optional top-down accent lighting, mesh screens that tuck away into hidden pockets for an unobstructed view, and a choice of add-on options, you can create a fireplace that suits your style and needs. Monessen also offers a range of vent-free log sets (sold separately) that perfectly complement the firebox, allowing you to complete the look with a 24″ Vent-Free Gas Log Set.
