Warming Trends UL250 250K BTU Linear CROSSFIRE Brass Burner Kit — UL250ALPL5610
The CROSSFIRE® burner is what made Warming Trends® a name installers ask for by brand. Instead of pushing gas through a ring of small ports, its patented brass jets pull air in and mix it before ignition — so you get a taller, fuller, more natural-looking flame on noticeably less gas than a conventional pan burner. This kit is built around the linear CROSSFIRE burner, ready to drop into a fire pit, fire table, or column you are building or refinishing. Add the 56" x 10" plate and choose your fuel and ignition above.
UL250 CROSSFIRE Brass Burner Kit Features
- Patented CROSSFIRE® brass jet design mixes air and gas before ignition for a taller, fuller flame than a conventional ring burner
- Up to 250,000 BTU on natural gas or propane — the burner itself is universal, so only the ignition is fuel-specific
- Solid brass burner body resists the corrosion and burn-through that eventually take out stainless and cast pan burners
- Patented WATERSTOP® fitting keeps water and debris out of the gas line and ignition components
- Optional 56" x 10" plate ships cut and finished — no fabrication needed on site
- 5 ignition paths, from a simple match lit key valve upward
- Designed, engineered, and assembled in the USA, and backed by a lifetime warranty on the brass burner
Ignition Options
Every CROSSFIRE® burner ships ready for the ignition you choose above. The systems differ in how you light the burner, whether they need power at the fire feature, how much gas they can pass, and — the one worth reading twice — whether they include an automatic safety gas shut-off.
-
Match Lit — The simplest and least expensive option — open the key valve and light the burner with a lighter. There is no automatic safety gas shut-off.
-
Push Button — Piezo (spark igniter). Turn the key valve and press the button to light the burner, so you never need a flame in hand. There is no automatic safety gas shut-off.
-
Carbon 3V (battery driven) — A battery-operated electronic ignition with an on/off switch and an available remote control. No electricity required, with an automatic safety gas shut-off. Rated up to 360,000 BTU.
-
Cobalt 12V — A 12-volt electronic system, ideal for installations near water. Multiple control options including remote control and home automation, with an automatic safety gas shut-off. Rated up to 490,000 BTU.
-
Platinum 24V — A 24-volt electronic system delivering up to 680,000 BTU. Multiple control options including remote control and home automation, with an automatic safety gas shut-off.
Because this burner is rated at 250,000 BTU, the Mercury system is not offered on this listing — it cannot pass that much gas.
What's Included, What's Required (but purchased separately), and What's Optional
This is a burner kit, not a finished fire feature — it supplies the burning half and you supply the enclosure. Here is exactly how that breaks down.
-
Included: the linear CROSSFIRE® brass burner and the FK2 connection kit — flex gas line, connectors, and key valve.
-
You choose above: fuel type, the 56" x 10" plate, and which ignition system is fitted.
-
Required to complete the installation, purchased separately: a burner plate (select the standard size above, call us for a custom size, or select "No Thanks" and supply your own), an enclosure to house the burner, fire glass or lava rock to cover it, and a gas line sized and run by a qualified installer that meets the specifications outlined in the installation manual AND any local municipality code requirements.
-
Optional: a premium aluminum cover with handle, a wireless remote or dial timer if you go with an electronic ignition, and an access panel for the valve box.
