Square flat pan with square burner: a rimless plate and a single square ring of flame, 16.5 to 48 inches
The Outdoor Plus square flat pan and square burner is a basic insert for square fire pits you build yourself, made in the USA. Its rimless stainless steel plate rests atop your enclosure, hidden under lava rock or fire glass. A single center-fed square stainless steel ring traces the pit’s outline with flame. Choose 16.5, 18, 24, 30, 36, or 48 inches square.
Order it for natural gas or propane. Light it with a match, or add electronic ignition and start it with a button. Want a pan that hangs inside the opening?

FAQ
What is the appeal of the plain square-on-square set?
Honesty and price. The OPT-999BP series pairs a square flat pan with a simple stainless square burner tracing its perimeter — no bullet ports, no sculpture, just an even frame of flame around the media bed. It is the workhorse choice when the surround carries the design.
What sizes does the square flat pan burner set come in?
Six squares: 16.5, 18, 24, 30, 36 and 48 inches — OPT-999BP16 through OPT-999BP48. The 16.5-inch is among the smallest square sets TOP offers, sized for columns and compact tables; the 48 anchors a full gathering feature.
What are the ignition options on the 999 series?
Pan and burner only for match lighting, Match Lit with Flame Sense (LC certified), Flame Sense with Spark, Low Voltage Electronic (CSA certified) and Plug and Play (CSA certified) — factory-configured at order across all six sizes.
How does hand-lighting a square burner go?
Open the key valve slightly, touch a long lighter to one side of the square, and flame runs the perimeter in moments. Dial height at the valve once the full frame is lit. As always: valve open only when you are ready to light, so gas never pools.
Would this pan suit a DIY square fire table?
It is the budget-smart core for one — frame the top, cut to the 24 or 30-inch pan, set it flush and finish the edges, and you have the anatomy of a production fire pit table at component cost. Licensed installer on the gas run and valve.
What clearance from the house does the square pan need?
Per the OPT-999BP spec clearances plus local code — structures, windows and eaves each carry minimums, and jurisdictions vary. Decide siting before the gas line goes in; the pan drops into any properly built enclosure, but the trench is dug once.
Should I order it in natural gas so a future owner can convert to propane?
No — order for the fuel the property runs now. TOP builds each square set for natural gas or liquid propane at the factory, and conversion is not the intended path. For an existing unit facing a fuel change, contact us to review options.
