Highridge Birch Vent Free Gas Logs
Whichever one you choose, you get a complete vent free set: the Highridge Birch concrete logs — five pieces keyed to the burner's pins, white birch bark over charred undersides, with a forked branch on top — on the Superior Nature-Flame pan burner that fits them, with its grate, ODS pilot, both ember materials, flex gas hose and anchoring hardware in the carton. The 18" set rides the 18" burner at 30,000 BTU/hr on natural gas (29,000 on propane with the millivolt burner, 30,000 with the electronic); the 24" and 30" sets ride the 24" burner at 39,000 BTU/hr (36,000 on propane). Pick a millivolt standing pilot — on its own, or as a kit with the GWMS2 wall switch, RCKIT4001 on/off remote or TRC thermostatic remote — or electronic ignition with the EcoFlow touchscreen remote; nothing on this page needs a power outlet. from $1,378, with a five-year limited warranty on the logs and grate.
Choose it if you want chunky, deeply barked concrete logs with split faces over a flickering ember bed and tall yellow flames, heat that stays in the room (99% heater rated, damper closed) in an existing masonry or UL127 fireplace or a listed vent free firebox, and you can give it the opening it needs: 26" of front width, 17" high and 15" deep for the 18" set, 29" x 19" x 15" for the 24", 33" x 19" x 15" for the 30".
It is not right as a primary heat source — it is a supplemental heater beside your central system. It cannot go in a bedroom or bathroom, in a recreational vehicle, in a factory-built fireplace whose instructions exclude unvented gas logs, or behind glass doors that will be closed while it runs, and it must run behind a fireplace screen. The room has to be big enough — 50 cubic feet for every 1,000 BTU/hr of gas appliances in it, about 1,500 cubic feet for the 18" set and 1,950 for the 24" and 30" — and the wall above the opening must be non-combustible for at least 8". Curtains and furniture stay 36" from the front.
Specifications
The minimum fireplace for the 18" set is 26" wide at the front, 17" across the back, 17" high and 15" deep; the 24" set needs 29" front, 22" rear and 19" high; the 30" set 33" front, 25" rear and 19" high, both 15" deep. A side wall stays 16" from the side of the fireplace and 42" above the top of the opening, with 36" clear in front; the facing directly above the opening must be non-combustible for 12" on the 24" and 30" sizes, or for 8" if you fit the GA6050 hood, and a combustible mantel sits 14" to 24" above the opening depending on its depth and the log size — see Figures 6 and 7 on page 11 of the installation manual, or ask us. At floor level the burner keeps 14" from combustible flooring or is raised 5" on non-combustible material. Inlet pressure runs 5" to 10.5" W.C. on natural gas and 11" to 14" W.C. on propane through a 3/8" NPT connection; each burner is built for one gas and cannot be converted, and propane needs an installer-supplied external regulator. The base anchors to the fireplace floor with the masonry screws in its hardware package.
Highridge Birch vs. the other Nature-Flame log sets
All four Nature-Flame log sets ride the same burner in the same three sizes, with the same fuels, ignitions, controls and ratings, and each needs the same fireplace opening for a given size — what changes is the stack. Highridge Birch is five white birch logs with charred undersides and a forked branch on top; Granite Ridge is six heavy, deeply barked concrete pieces; Emberwood Split is eight split concrete logs, charred on their faces with ash-grey cracked tops; Silverstone Timber is five high-definition ceramic logs (six in the 30") with a crossover piece and a lighter, more detailed look. This Highridge Birch set starts at from $1,378; Granite Ridge at from $1,238, Emberwood Split at from $1,308, Silverstone Timber at from $1,468.
Features
- Highridge Birch concrete logs in 18", 24" or 30" — five pieces, white birch bark over charred undersides, with a forked branch on top, keyed to the burner's pins so the flames never touch a log
- Nature-Flame pan burner: tall random yellow flames over a flickering ember bed — both ember materials ship in the carton — on a base that reads as a wood-burning grate
- 30,000 BTU/hr on the 18" burner and 39,000 BTU/hr on the 24" burner that carries the 24" and 30" logs (natural gas, high fire; 29,000-30,000 and 36,000 on propane), heater rated at 99% efficiency
- No electricity: the millivolt burner lights from a piezo igniter and sets its flame between HI and LO on the knob; the electronic burner runs on a battery pack with the EcoFlow touchscreen remote (manual, thermostat and program modes, three flame heights)
- Vent free with an ODS safety pilot to ANSI Z21.11.2 — in a masonry fireplace, a UL127 factory-built fireplace or a listed vent free firebox
- Approved for manufactured (mobile) homes where local codes allow, with IHP's five-year limited warranty on the logs and grate
Answers to common questions
Does it need a chimney or a vent?
No — every configuration on this page is a vent free room heater approved to ANSI Z21.11.2: it burns room air with the fireplace damper closed, so nothing goes up the chimney and all the heat stays in the room, with the ODS pilot as the safety. The room has to be big enough — 50 cubic feet for every 1,000 BTU/hr of gas appliances in it, so about 1,500 cubic feet for a 30,000 BTU/hr burner and 1,950 for the 39,000 BTU/hr burner — or it needs ventilation openings. State and local codes in some areas prohibit vent free appliances, and Massachusetts bars them from bedrooms and bathrooms, so check your codes before you buy.
What size fireplace opening do I need?
Measure the opening the burner and logs will sit in — the requirement is the same for every fuel and ignition, and it changes only with the log size you pick. The 18" set on its 18" burner needs 26" of front width, 17" across the back, 17" of height and 15" of depth; the 24" set on the 24" burner needs 29" front, 22" rear and 19" high; the 30" set on the same 24" burner needs 33" front, 25" rear and 19" high, all 15" deep. The rear width matters because the rear log sits against the back of the firebox. If a fireplace is deep enough but the back is narrow, drop a size rather than force the logs.
How close can a mantel, the wall or the ceiling be?
The clearances are the same for every configuration here except where the 18" size is a little more forgiving. The ceiling must be at least 42" above the top of the fireplace opening and a side wall 16" from the fireplace; the wall directly above the opening must be non-combustible (slate, marble or tile at least 1/2" thick) for at least 8" — 12" or more and you are done, and on the 24" and 30" sizes the GA6050 fireplace hood is what makes a facing of only 8" to 12" work (the 18" needs no hood at all). Under 8" the facing has to be extended to at least 8"; if it cannot be, this is not the right fireplace for it. A combustible mantel needs, from the top of the opening to its underside: 2-1/2" deep 14" (18" set) or 18" (24"/30"), 6" deep 17" or 20", 8" deep 19" or 22", 10" deep 20" or 24"; with the hood those drop to 8", 12", 15", 18" and 20" for 12" deep. Shelves and window sills count. See Figures 6 and 7 on page 11 of the installation manual, or send us your mantel depth and we will check it with you. In a vent free firebox the firebox maker's clearances also apply.
What’s included, what’s required, and what’s optional?
-
Included in the box: Highridge Birch concrete log set — five concrete logs; Nature-Flame vent free burner in the width the logs need (18" or 24"), with its integral grate, ODS safety pilot, approved flexible gas hose with 3/8" NPT x 3/8" flare fitting and the masonry-screw hardware package; Two ember materials — glowing embers laid beside the burner ports and platinum bright embers on top; With the millivolt burner: piezo igniter, HI-LO flame knob and AUTO/OFF/ON switch on the burner, plus the GWMS2 wall switch, RCKIT4001 on/off remote or TRC thermostatic remote the Ignition choice names. With electronic ignition: EcoFlow touchscreen remote (four AAA) and the control module's battery pack.
-
Required to complete the installation, purchased separately: Gas line - a natural gas or propane supply piped to the fireplace by a qualified installer, with an equipment shutoff valve, 1/8" NPT test tap and sediment trap; propane also needs an installer-supplied external regulator set to 11"-14" W.C; A fireplace or firebox to house it - a solid-fuel masonry fireplace, a UL127 factory-built fireplace or a listed vent free firebox with a non-combustible facing above the opening and an opening at least 26" x 17" x 15" (18" logs), 29" x 19" x 15" (24") or 33" x 19" x 15" (30").
-
Optional: Black Fireplace Hood (fits 28"-48" openings) — the part that lets you install with less clearance. It shortens every minimum mantel height, and on the 24" and 30" sizes it is how a non-combustible facing of only 8" to 12" works where 12" is otherwise wanted; Floor Media Kit (volcanic stone, embers, cinders) and Decorative Volcanic Stone to dress the fireplace floor — the set runs fully without them where the clearances are already met.
Will it work in a power outage?
Yes, whichever ignition you pick — nothing on this page plugs into the wall. The millivolt standing-pilot burner lights from a piezo igniter and runs on its own valve, and the electronic-ignition burner runs its control module from a battery pack with four AAA batteries in the EcoFlow remote. It may even serve as your primary heat source while the power is out; the rest of the time it is a supplemental heater.
Which ignition should I pick, and what does each control do?
All five choices sell the same Nature-Flame burner width in your fuel; they differ in how you light and run it. The four Standing Pilot rungs are the millivolt burner — a piezo lights the pilot, the valve powers itself, and you set the flame anywhere between HI and LO on the knob. The manual rung is that burner alone, run from its own switch; the wall switch rung adds the GWMS2 wall switch (and enables the burner's AUTO position); the remote control rung adds the RCKIT4001 remote and its receiver; the thermostatic remote rung adds the TRC receiver and thermostat remote so the set holds a room temperature. Each is a kit — the burner ships remote-ready and the installer wires the control to the terminals on its valve. Electronic Ignition is a different burner: it lights the pilot on command from the included EcoFlow touchscreen remote, runs on a battery pack, and gives manual, thermostat and weekday/weekend program modes with three flame heights, a child lock and a 95 F room shutdown. Either way the logs, burner and ratings are the same.
Can it go in a manufactured or mobile home?
Yes — every burner on this page is approved for a permanently located manufactured (mobile) home where local codes do not prohibit it, in a fireplace or firebox that meets the same size and clearance rules as any other install. It is never approved for a recreational vehicle.
Does buying from The Torch Guys affect the Superior warranty?
No. IHP's five-year limited warranty on Superior vent free gas log sets applies to product bought through a listed supplier of IHP, and The Torch Guys is an authorized Superior dealer — we register the set and, if you ever need to claim, we deal with the manufacturer on your behalf rather than handing you a phone number. The logs and grate carry the full five years, gas components and the remote one year, other parts 90 days; the warranty stays with the original owner. Keep your invoice and the model number from the data plate on the grate; we hold the rest on file.
