At 54\" long and 36\" wide, its sweeping curves and offset flame create a dramatic focal point that transforms any patio, terrace, or outdoor lounge into an unforgettable gathering space. Powered by a Warming Trends Crossfire Brass Burner capable of 120K-190K BTU output, the Nyx delivers a flame twice the height of typical prefabricated fire pits while consuming roughly half the natural gas.\n\u003c\/p\u003e\n\u003cp\u003e\n  Each piece is individually cast and finished by hand, meaning no two Nyx fire pits are exactly alike - the natural character of the concrete ensures your fire feature is truly one of a kind. Available in four refined finishes and compatible with both natural gas and liquid propane, the Nyx is as versatile as it is striking. For discerning homeowners and design-forward outdoor spaces, this is a fire feature that commands attention from the moment it's lit.\n\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHand-Crafted GFRC Construction:\u003c\/strong\u003e Built from glass fiber reinforced concrete with high-strength alkali-resistant glass fibers for exceptional durability and a refined, organic aesthetic.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarming Trends Crossfire Brass Burner (120K-190K BTU):\u003c\/strong\u003e Produces a taller, brighter, fuller flame using a precise air-to-gas ratio - resembling a natural wood-burning fire.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOffset Flame Design:\u003c\/strong\u003e The distinctive offset burner placement creates a visually dynamic, asymmetrical flame that sets the Nyx apart from conventional fire pits.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNatural Gas or Propane Compatible:\u003c\/strong\u003e 1\/2\" pipe opening works with both natural gas and liquid propane, offering flexible installation options.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions: 54\" L x 36\" W x 16\" H:\u003c\/strong\u003e Generous rectangular proportions ideal for larger seating areas and outdoor living spaces.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight: 200-400 lbs:\u003c\/strong\u003e Substantial weight ensures stability; professional installation and delivery planning recommended.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePremium Black Rolled Lava Rock Fill (1-3\"):\u003c\/strong\u003e Included fill media provides a clean, polished look and excellent heat radiation around the burner.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlack Marine-Grade Cover with Nisho Logo:\u003c\/strong\u003e Included weather-resistant cover protects the fire vessel when not in use.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e4 Hand-Crafted Finish Options:\u003c\/strong\u003e Choose from Birch, Smoke, Carbon, or Onyx - each with natural variation unique to the GFRC process.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eComplete Hardware Included:\u003c\/strong\u003e Comes with key valve, flex hose, and aluminum burner plate for a straightforward installation process.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003chr\u003e\n\n\u003ch2\u003eFinish Options \u0026amp; Which to Choose\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBirch:\u003c\/strong\u003e A light, warm concrete finish with soft tonal variation.

It delivers the beautiful, natural appearance of cast concrete while being significantly lighter and more impact-resistant than solid poured concrete. For fire features, GFRC is an excellent choice because it handles thermal cycling well, resists moisture, and allows for detailed hand-crafted shaping that solid concrete cannot achieve as easily.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eDoes the Nyx fire pit work with both natural gas and propane?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eYes.

The finish photos are representative, but your piece may have slight differences that reflect the character of genuine artisan concrete work. Additionally, small hairline cracks may develop during the concrete curing process; this is normal and does not affect structural integrity or long-term performance.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eWhat does professional installation involve for this fire feature?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eDue to the weight of the Nyx (200-400 lbs) and the requirement for a gas line connection, professional installation is strongly recommended. You will need a licensed gas plumber or contractor to run the gas supply line to the fire pit's location and connect it to the 1\/2\" pipe opening. The burner hardware (key valve and flex hose) is included. Always check local codes and permit requirements before installation.\u003c\/p\u003e\n\u003c\/details\u003e\n\u003cdetails\u003e\n\u003csummary\u003eHow does the Crossfire Brass Burner compare to a standard fire pit burner?\u003c\/summary\u003e\n\u003cp class=\"faq-content\"\u003eThe Warming Trends Crossfire Brass Burner uses a patented multi-port orifice design that optimizes the air-to-gas mixture at the point of combustion.
