Monessen · LoRider Vent-Free Firebox
Flames close to the floor, the way a real hearth sits
LoRider pairs a flush, low hearth with a tall opening, so the fire reads like a classic wood-burning fireplace. Choose 36 or 42 inches and one of four interior panel styles.
01 · Hearth
Flush, low hearth
The hearth sits nearly at floor level, which puts the flames right where your eye lands.
02 · Viewing
Tall, wide opening
A large viewing area shows off a full log set or a modern glass burner.
Fuel & Compatibility
This firebox does not burn fuel by itself. Use only an approved gas-fired decorative room heater and its matched log set. The separately selected burner determines fuel, ignition and heat input. Do not burn wood in this firebox.
Product Details
- Flush-hearth design with an expansive viewing area.
- Mesh screens retract into hideaway pockets.
- Clean-face appearance works with a planned tile, stone or mantel finish.
- See the SKU table for the selected interior configuration.
What comes with your order
Selected Lo-Rider firebox with its listed interior configuration, hood and mesh screens. Approved burner, logs and optional accessories are sold separately.

Questions Before You Order
Are the burner and logs included?
No. This is a firebox listing. Choose a manufacturer-approved burner and compatible log set separately.
Can I use the nominal size as the framing dimension?
No. Use the model-specific framing dimensions and required clearances in the installation manual. The nominal size refers to the firebox family, not the complete installation opening.
