Warming Trends UDT400 400K BTU Double Tree-Style CROSSFIRE Brass Burner Kit — UDT400ALPL5018
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 41.25" x 11.25" double tree-style CROSSFIRE burner, ready to drop into a fire pit, fire table, or column you are building or refinishing. Add the 50" x 18" plate and choose your fuel and ignition above.
UDT400 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 400,000 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 50" x 18" plate ships cut and finished — no fabrication needed on site
- 4 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.
-
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 400,000 BTU, the Mercury and Carbon 3V systems are not offered on this listing — they 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 41.25" x 11.25" double tree-style CROSSFIRE® brass burner and the burner itself — note this family does not include a key valve kit, so plan the gas connection with your installer.
-
You choose above: fuel type, the 50" x 18" 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.
