Montigo Exemplar See-Through Linear Fireplace, 61¼" Viewing Area

The Montigo Exemplar R520STL is built around a 61¼" × 18⅛" see-through viewing area — a ribbon of fire that reads equally well from both sides of a wall partition, room divider, or open-plan living space. At 80,000 BTU/hr on liquid propane, it delivers serious heat output behind a genuinely architectural face.

The linear burner design produces a clean, horizontal flame presentation that pairs naturally with contemporary interiors. Glass accessories are included, allowing you to tailor the look of the firebox to the room rather than the other way around. Montigo specifies that only Montigo-supplied components and accessories should be used — a detail worth noting during the planning stage, and one that protects the integrity of the installation long-term.

Ignition is handled by an HSI electronic ignition system with SIT Electronic IPI (Intermittent Pilot Ignition), which means the pilot only runs when the fireplace is in use. It's a small detail that adds up over a heating season.

Installation flexibility is a genuine selling point here. The R520STL ships convertible between top vent and rear vent configurations, and the power vent system opens up placement options that a traditional direct-vent unit simply cannot match — including interior walls where running a flue to the exterior would otherwise be impractical or impossible. The R520STL is also compatible with the R620STL from the same Exemplar See-Through series, sharing power venting components, which matters if you're speccing a multi-unit installation or a larger project where consistency of parts is a priority.

Front width measures 65½", back width 74³⁄₁₆", with a height of 45⅞" or 47" and a depth of 24⅝" or 23¾" depending on configuration. These dimensions reward careful rough-opening planning — your installer will want them early.

The R520STL sits at a price point that reflects what it is: a high-output, see-through linear fireplace from a manufacturer known for precision engineering, not a showroom prop dressed up to look the part.
