Triple-Flame Vent Free Gas Log Burner
The burner alone, for a replacement or for logs you already own. The Superior Triple-Flame vent free burner puts two rows of flame and a third behind the logs over a glowing ember bed, in an 18" length for 18" Triple-Flame log sets and a 24" length for 24" and 30" sets — 30,000 BTU/hr high on the 18" millivolt and variable burners, 39,000 on the 24", natural gas or propane, heater rated for a masonry fireplace, UL127 factory-built fireplace or listed vent free firebox, from $1,019, with a three-year limited warranty on the grate.
Choose it if you already have — or are buying separately — a Superior Rugged Stack or Wild Timber log set and need the burner under it: the 18" burner for 18" logs, the 24" burner for 24" or 30" logs. Pick the millivolt burner for a fire that runs with no power and add the wall switch, on/off remote or thermostatic remote you want; the variable-flame burner for five flame heights and a room thermostat on its ProFlame remote; the electronic-ignition burner for a self-lighting pilot and the EcoFlow touch-screen remote with thermostat and weekday/weekend modes, all on batteries. If you do not yet own the logs, a Triple-Flame log set is the right purchase — it comes with this burner.
It is not a complete log set — no logs ship with it and it is never run without a Rugged Stack or Wild Timber set in place; nor will it take another brand's logs. It is not for a bedroom, a bathroom or a recreational vehicle, not a primary heat source except during a power outage, and not for a room that cannot supply its combustion air — the confined-space test is 50 cubic feet per 1,000 BTU/hr. It does not go in a factory-built fireplace whose own instructions exclude unvented gas logs, and it is not for outdoor use.
Specifications
Under 18" logs the 18" burner needs a firebox at least 28" wide at the front, 20" at the rear, 19" high and 14" deep; the 24" burner needs 32" x 22" x 19" x 14" under 24" logs and 40" x 30" x 19" x 14" under 30" logs — the variable-flame burner asks for 20" of height. A side wall stays 16" from the side of the fireplace and the ceiling 42" above the top of the fireplace opening, with 36" clear in front; at floor level the fireplace keeps 14" to combustibles or the unit is raised 5" above combustible flooring, and at least 8" of noncombustible material above the opening — with 12" or more no hood is needed, and on the 24" burner the Black Fireplace Hood is what makes a facing of only 8" to 12" work. Mantel heights are charted in Figures 6 and 7 on page 11 of the installation manual. The inlet is 3/8" NPT at the burner's regulator; inlet pressure 5"-10.5" w.c. natural gas, 11"-14" propane. Ratings: 21,000-30,000 BTU/hr on the 18" millivolt and variable burners (24,000 low on propane), 24,000-28,000 on the 18" electronic burner, 28,000-39,000 on every 24" burner.

Answers to common questions
Which Triple-Flame burner do I need for my logs?
The 18" burner (TF18) takes the 18" Rugged Stack or Wild Timber set; the 24" burner (TF2430) takes both the 24" and the 30" sets — there is no 30" burner. Under 18" logs the firebox must be at least 28" wide at the front, 20" at the rear, 19" high and 14" deep; under 24" logs 32" x 22" x 19" x 14"; under 30" logs 40" x 30" x 19" x 14" — and with the variable-flame burner the minimum firebox height is 20" in all three sizes, not only the 30". These burners are listed for Superior's Triple-Flame logs only.
What’s included, what’s required, and what’s optional?
-
Included in the box: The Triple-Flame burner base assembly with grate, ODS safety pilot, hardware kit with masonry screws, flexible gas hose and fittings, a bag of volcanic stone, a bag of Glowing Embers and a Platinum Bright Embers kit.
-
Required to complete the installation, purchased separately: Log Set - a Superior Rugged Stack or Wild Timber set sized to the burner: 18" logs for the 18" burner, 24" or 30" logs for the 24" burner; the burner is listed for these logs only and is never run without them in place; A masonry fireplace, UL127 factory-built fireplace or listed vent free firebox that meets the minimum firebox size for the log length, and the gas connection — piping, an equipment shutoff valve with test tap, a sediment trap and LP-resistant sealant; propane also needs an external regulator set to 11"-14" w.c.
-
Optional: Black Fireplace Hood — the part that lets you install with less clearance. On the 24" burner it is how a noncombustible facing of only 8" to 12" works where 12" is otherwise wanted, and on any size, the 18" included, it shortens the minimum mantel height (the manual's Figure 7 chart instead of Figure 6). Where your facing and mantel already clear, you do not need it. Floor Media Kit — extra lava rock, embers and cinders for the firebox floor.
Does it need a chimney or a vent?
No. It is a vent free heater, design-certified to ANSI Z21.11.2, run with the fireplace damper closed so the heat stays in the room — rated at 99% efficiency by the manufacturer. It takes its combustion air from the room, so the room must be large enough or ventilated, and the fireplace screen stays in place with any glass doors fully open while it burns. State and local codes in some areas prohibit vent free appliances, so check yours before you buy.
Millivolt, variable flame or electronic ignition — what is the difference?
The millivolt burner has a standing pilot you light with a push-button igniter and a LO-HI flame knob at the burner; it needs no power and is remote-ready, so we pair it here with Superior's wall switch, on/off remote or thermostatic remote kit if you want one. The variable-flame burner is a different burner with a variable valve: its ProFlame remote comes in the box and gives on/off, five flame heights, a room thermostat and a child lock. The electronic-ignition burner lights its own pilot from a battery pack and comes with the EcoFlow touch-screen remote — manual, thermostat and weekday/weekend program modes with three flame levels — again with no household power.
Can I put a mantel or a shelf above it, and where can it not go?
A mantel is fine at the right height. How high depends on how deep the mantel is and whether you fit the Black Fireplace Hood — the minimums are charted in Figures 6 and 7 on page 11 of the installation manual, and at least 8" of noncombustible facing must run above the opening. The hood is what buys you room — it shortens every minimum mantel height (the Figure 7 chart instead of Figure 6) and drops the noncombustible facing the 24" and 30" sizes need from 12" to 8". If even that will not reach, the mantel has to be raised or removed, and if none of that is possible this is not the right fireplace for the set. Never install it in a bedroom, a bathroom or a recreational vehicle, within 36" of curtains or furniture, or in a windy or high-traffic spot; Massachusetts bars vent free logs from bedrooms and bathrooms outright.
Can it go in a manufactured home?
Yes, in a permanently sited manufactured (mobile) home where local codes allow — but never in a recreational vehicle.
How does the warranty work if something goes wrong?
Superior warrants the grate for three years, the gas components and the remote for one year and other parts for 90 days, for the original owner when the burner is installed by a licensed contractor — and The Torch Guys handles it for you: as an authorized Superior dealer we register the appliance and, if you ever need to claim, we deal with the manufacturer on your behalf rather than handing you a phone number. Keep your invoice and the model number; we hold the rest on file.
