12-inch wide flat pan with H burner: an even stainless flame the full length of a linear pit, 24 to 96 inches
The Outdoor Plus 12 inch wide rectangular flat pan and H burner is an insert for long rectangular fire pits. The rimless stainless plate rests atop the enclosure beneath lava rock or fire glass. Two full-length drilled tubes join centrally like an H, giving even flames along both sides. Made in the USA, it comes 24 to 96 inches long by 12 inches wide.
Order it for natural gas or propane. Light it with a match, or add electronic ignition and start it with a button. For a lipped opening, try the 12-inch drop-in pan with H burner, which hangs inside the enclosure. The 12 inch H burner set ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.

FAQ
What does the H pattern do that a straight burner cannot?
The stainless H burner runs two parallel rails linked by a crossbar, pushing flame toward both long edges of the 12-inch pan. A single straight tube leaves wide shoulders of unlit media; the H fills the pan visually, which is why it is the default for wider rectangular features.
What sizes can I order this pan and H burner in?
Nine lengths from 24 to 96 inches — SKUs OPT-REFD1224 through OPT-REFD1296 — with the spec sheets covering both 12-inch and 18-inch pan widths. The 12-inch version here suits walls and tables where you want real flame body without an oversized cut-out.
Which ignition systems are available on the OPT-REFD series?
Five tiers: 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). Flame Sense versions shut gas off if the flame blows out — worth it in windy yards.
How would I build a propane fire pit with this kit?
Order the set built for liquid propane, frame your enclosure with ventilation for the tank or run a buried LP line, then drop the flat pan across the opening. It is the proven skeleton of a custom gas fire pit — a licensed installer makes the connections and leak-tests everything.
How far from the house should the finished feature sit?
Follow the clearances in the OPT-REFD spec sheet and your local code — many jurisdictions want gas features roughly 10 feet from structures, though listed clearances can allow closer. Decide placement before running gas; moving a 96 by 12-inch feature later is nobody’s idea of fun.
Does the 12-inch H burner come as propane or natural gas?
Whichever you specify — every 12-inch H burner set is built to order for natural gas or liquid propane. There is no field-flip between fuels, so confirm what the property has (or what your installer plans to run) before you order the pan.
Can you make s’mores over a gas fire pit like this?
Absolutely — the clean flame off the H burner is arguably better for s’mores than wood, since there is no smoke to flavor the marshmallow. Toast above the flame tips, keep graham cracker assembly off the pan edge, and brush sugar drips off the media when cool.
