Description
Overall Dimensions: 48 in. square or circular aluminum plate; CFB350 original-style burner
This Warming Trends match light kit builds a 48 in. gas fire pit around the CROSSFIRE CFB350, an original-style 100% brass burner rated 350,000 BTU. It comes with a water-jet cut 48 in. aluminum plate, circular or square, with drainage vents, plus the dual flex line and key valve parts to connect it.
It suits a large round or square fire pit where you want a tall, full flame without running power to the fire pit. The CFB350 is the burner Warming Trends' size guide matches to 48 in. interiors.

What Is Included and What You Will Need
- Included: CFB350 burner, 48 in. aluminum plate and an FK2 kit with two 36 in. x 3/4 in. flex lines, four 3/4 in. flared fittings, a 3/4 in. key valve with 3 in. and 12 in. keys, two 3/4 x 3 in. nipples, two 3/4 in. tees and a 3/4 x 1/2 in. reducer
- Required, sold separately: fire-rated media such as Warming Trends black lava rock (BLR) or rolled lava rock (LRR)
- Required: a non-combustible, vented enclosure with a 48 in. interior and a gas line with an exterior shutoff, run by a licensed installer
Installation Notes
Warming Trends requires a non-combustible enclosure with venting on at least two opposing sides, 18 sq in. minimum each, placed mid to low; the cavity must never be filled with gravel, crushed rock or concrete, and the burner should sit 4 to 6 in. below the top to protect the flame from wind. Support the plate or pan on blocks, bricks or L-brackets, never on the valve. Keep 36 in. horizontally and at least 84 in. overhead from combustible materials (Version 6 manual), fit a gas shutoff outside the fire feature, and have a licensed gas professional make the connection and leak test. Cover the burner with fire-rated media no more than 1/2 in. above the jets; never use gravel, pebbles or river rock. A center support under the plate is recommended on plates over 30 in. Certification: the CFB350 burner in this kit does not appear on the Warming Trends certified burner list in the Version 6 manual (6/26) or in ICC-ES listing PMG-1213 (effective March 2026), so this match lit kit is not a certified configuration. The nearest certified CROSSFIRE Original sizes are the CFB290, certified match lit, and the CFB300, certified only with the Platinum or Cobalt ignition systems or the 24V high capacity electronic ignition kits (24VIKHC and P24VIKHC). Because it is not a certified configuration, installation requires approval from your local code official (the authority having jurisdiction) before you buy and install it. For New York City addresses, outdoor gas fire features and their gas piping fall under the NYC Fuel Gas Code and Department of Buildings permitting, and propane at residences is restricted by the NYC Fire Code, so the approval path for a built-in fire pit must be confirmed before you buy. Book a design consultation and we will plan the enclosure, venting and gas run.

Frequently Asked Questions
What size fire pit does it fit?
A 48 in. interior, round or square, per the Warming Trends burner size guide; choose the plate shape to match.
Does it need electricity?
No. It is match lit with a key valve, so no power is needed at the fire pit.
What media can I use?
Fire-rated media made for fire features, such as lava rock or fire glass, placed on the plate rather than dumped over the burner and no more than 1/2 in. above the jets. Never use gravel, pebbles or river rock.
Can I install this in New York City?
Possibly, but outdoor gas fire features and their gas piping need NYC Fuel Gas Code and Department of Buildings approval, and propane at residences is restricted by the NYC Fire Code. Talk to us before you order.
