Monessen Lo-Rider 42 Inch LCUF Clean Face Vent Free Gas Firebox with Panels - LCUF42CR-C
The Monessen Lo-Rider Series offers a sleek, low-profile hearth that gives your firebox a modern, almost floor-level look. It creates a large, open viewing area and doesn’t require a chimney, flue, or vent, making it perfect for spaces where a traditional fireplace is impractical or expensive to install. With just a simple gas line connection, it’s an affordable solution for any room.
The Lo-Rider features an extra-tall opening, paired with your choice of Monessen vent-free log sets and hideaway screen pockets, giving you the charm of a classic wood-burning fireplace with a modern twist. It’s available in three sizes—32", 36", and 42"—and a variety of stylish interior panels.
These vent-free fireboxes are flexible and cost-effective, especially for homes without a fireplace. They can be installed in a wall or a free-standing cabinet, and with zero-clearance installation, they can sit flush against walls or wood. Monessen also offers a range of vent-free log sets (sold separately) that perfectly complement your new firebox.
The Lo-Rider firebox works with any 30" Monessen Vent-Free Gas Log Set and delivers great heat and stunning flames.
