Montigo Exemplar See-Through Linear Fireplace, 56¾" Framing Width

The Montigo Exemplar R320STL is a see-through, linear liquid propane fireplace built around a 56¾" framing width and a 42,000 BTU maximum output. Two rooms share one flame — a detail that sounds simple until you realize how rarely it's executed cleanly at this scale. The glass opening spans 37¼" wide by 16⅛" tall, giving both sides an unobstructed view of the linear burner and its standard ice fireglass bed.

Contemporary in every proportion, the Exemplar series uses a linear burner format that spreads flame across the full width of the firebox rather than mounding it in the center. The result is a long, low ribbon of fire that suits modern and transitional interiors equally well. Ice fireglass is included as standard media, though optional driftwood, speckled stones, and additional glass media are available if you'd like a different texture or palette.

On the technical side, the R320STL is a zero-clearance unit, which simplifies rough-in considerably — framing dimensions are 56¾" wide, 47" tall, and 23¾" deep. Venting runs through a dedicated power vent system sized for Montigo's 300-Series components: compatible options include the PVHFL58-300 (flush louvered wall termination), PVHEX58-300 (standard wall termination), PVVEX58-300 (roof termination), and PVHIN58-300 (inline power vent). Both horizontal and vertical termination paths are supported, giving installers meaningful flexibility on routing. The direct-vent sealed combustion design keeps outside air feeding the firebox rather than drawing from the conditioned space — a meaningful efficiency consideration in well-insulated homes.

Ignition is handled by a Honeywell HSI (hot surface ignition) system, a proven, reliable mechanism that doesn't require a standing pilot. The inner vent diameter is 5" with an 8" outer vent — standard 300-Series sizing that works across the compatible power vent lineup above. Tempered glass fronts both viewing sides.

For control, the RXM40VAC wireless remote is available as an optional accessory, adding convenient operation without hardwiring a wall switch — useful when the fireplace sits on a partition wall between two rooms where switch placement is inherently awkward.

The R320STL is a considered choice for architects and designers who want a fireplace that functions as a genuine architectural element rather than an afterthought. At $10,779, it's priced in line with what serious double-sided linear construction demands — and it ships ready to perform at that level.
