AWEIS Ignition: All-Weather Electronic Ignition System (24VAC) — commercial-grade pilot rated for rain and 55 mph winds. Integrated Tabletop Surface: Tapered sides create a 7.5" (42") or 10.5" (48") ledge around the fire bowl. 12" Fire Ring Burner: Flat burner pan with 12" ring for even flame distribution. 24V Transformer Included: Requires a 120VAC outdoor GFCI outlet.

Frequently Asked Questions What's the difference between the 42" and 48" Legacy Square?Both run 85,000 BTU/hr. The 48" adds 150 lbs and a wider 10.5" tabletop ledge vs. 7.5" on the 42". For larger seating groups or bigger patios, the 48" provides a more proportional scale. Can this be used as a table when the fire isn't running?Yes — the tapered sides and flat ledge function as a low side table. The 48" provides a 10.5" surface width. Not designed for food prep or sustained heavy loads. NG vs. Propane — what's the difference?NG runs off a dedicated gas line at lower ongoing fuel cost. LP requires a tank with periodic refills. LP units include an air mixer and backup safety valve. The two SKUs are not interchangeable in the field. What's included in the kit?Fire pit body, AWEIS ignition, 24V transformer, 12" fire ring burner, and flat burner pan. Fire glass is sold separately. What's the lead time?6–8 weeks from order. Fire by Design builds to order — confirm color selection at time of purchase. Does this require a licensed contractor for installation?Yes for the gas connection. The 24V transformer is plug-in. A GFCI outdoor outlet must be present within transformer cord reach. Browse More Fire by Design See the full Fire by Design collection or browse all outdoor fire pits. Show more
