Monessen Lo-Rider Designer 36 Vent-Free Firebox

Clean-face circulating firebox with an angled interior and air channels designed to move warmth from a separately installed log heater into the room. Curtain mesh screens retract into concealed side pockets.

Gas-line access points and a junction box support the separately planned gas and electrical connections.

Includes two canopies and factory-installed refractory panels. The see-through opening serves both sides of the room divider.

Select a compatible listed vent-free gas log heater, matching burner, fuel type and controls separately. The heater must fit the firebox's minimum internal dimensions and remain within its 40,000 BTU/hr limit. This enclosure alone does not produce heat.

A regulated gas supply, site-appropriate framing, finishing materials, combustion/ventilation air and professional installation are required. Logs and burner must follow their own installation instructions as well as the firebox manual.

Install the supplied hood or canopies as directed. Plan electrical supply before closing the wall when using lights, a fan or electrically powered controls. Installation, materials, gas work, finishing, delivery, accessories and tax are separate.

Optional BLOTDL fan and MONALST accent lighting are identified in the exact-model manual. The website-linked MONAL-VF manual covers other fireboxes and is not used here for LSTF36-B.

Additional installation accessories: Outside-air kit — confirm current compatible kit. The manual names AK22 while the brochure names AK4; resolve the current kit before quoting.

For approved vent-free gas log heaters only; never burn wood or other solid fuel. The system is supplemental heat or decorative use, not a primary heating system.

Location, room air supply, fuel choice and local permission for vent-free use must be checked by the installer. Maintain unobstructed combustion and ventilation openings and follow both the heater and firebox manuals.

Use the see-through model's clearance diagrams on both sides; the canopies must remain installed. Frame and support the unit according to its own drawings.

Photos show complete installations with separate log heaters, burners, optional trim, liners and room finishes. Shared series photos may depict another size.

The outside-air kit name differs between manual and brochure; confirm the current compatible kit before ordering.
