American Fyre Designs Mariposa Vent-Free Outdoor Fireplace, 65" GFRC

The Mariposa vent-free outdoor fireplace by American Fyre Designs is built from pre-cast Glass Fiber Reinforced Concrete — a material chosen because it handles the demands of outdoor life without apology. At 970 pounds and 67 inches tall, this is not a fireplace that will tip over in a breeze, migrate across your patio, or leave anyone wondering whether it belongs there. It belongs there completely.

The unit measures 65 inches wide by 36 inches deep and arrives as a 7-piece assembly, which means the logistics are manageable even for something this substantial. Included from the factory: the fireplace unit itself, a hearth unit with a 16-inch Rectangle Bullnose profile, four herringbone firebox liners, and two installed refractory panels. The herringbone pattern inside the firebox isn't incidental — it reflects firelight with a warmth and depth that a plain liner simply cannot replicate.

Fuel flexibility is built in. The Mariposa runs on natural gas or propane, and the vent-free, free-standing configuration means you're not constrained by a wall, a chimney chase, or a gas line on one particular side of the yard. It's designed to work with R.H. Peterson Co. vented and unvented gas appliances, giving you a clear, manufacturer-supported path for the burner component.

When it comes to accessories, the Mariposa plays well with others — specifically its own family. The Model 8250-BL screen is compatible with the Mariposa (as well as the Phoenix and Grand Phoenix models), and the Model 8073RV-xx Chimney Rain Cap and rectangular GFRC cover are both confirmed fits. Protecting an investment of this scale between seasons is straightforward when the accessories are already specced out for you.

GFRC construction delivers the visual weight and textural character of cast stone without the structural impracticality of solid masonry at this scale. It holds its finish outdoors, resists cracking through temperature swings, and ages with the kind of quiet dignity that outdoor living spaces deserve. At $8,117, the Mariposa is priced as what it is: a permanent outdoor feature, not a seasonal accessory.

If you're planning an outdoor room that's meant to be used — not just photographed — this is a fireplace built to that standard.
