Superior Highridge Birch Nature-Flame Gas Logs
Superior Highridge Birch 30" Nature-Flame Vent-Free Gas Log Set LNF30HB
The Superior Highridge Birch 30" Nature-Flame Vent-Free Gas Log Set LNF30HB creates a wider birch-style fireplace presentation using detailed concrete cast refractory logs and Superior's Nature-Flame pan burner system. The 30-inch log set pairs with an approved 24-inch Nature-Flame burner to produce tall natural-yellow flames, varied flame movement, and a flickering ember bed. Natural Gas configurations operate from 28,000–39,000 BTU/hr, while Propane/LP configurations operate from 25,000–36,000 BTU/hr.
Your usable firebox measures at least 33" front width × 25" rear width × 19" height × 15" depth.
You understand that the 30" LNF30HB log set uses a compatible 24" Nature-Flame burner.
The burner is one of the approved Nature-Flame 24 / NF24 models.
You have selected the correct Natural Gas or Propane/LP configuration.
You have selected the appropriate millivolt or electronic control system.
The intended vent-free or vented installation satisfies the applicable Superior requirements.
Do Not Assume
That a 30" log set uses a 30" burner.
That any 24" gas-log burner is compatible.
That log length alone determines fireplace suitability.
That Natural Gas and Propane/LP configurations are interchangeable.
That millivolt models include the same controls as electronic models.
That the burner or damper clamp is automatically included.
That individual logs can be rearranged or substituted.
Critical burner-size distinction: The LNF30HB is a 30-inch log set paired with an approved 24-inch Nature-Flame burner. A 30-inch burner is not specified for this log set.
Highridge Birch 30" Overview
The Highridge Birch 30" is designed for larger qualifying fireplaces where a broader birch-style log presentation is desired while retaining the Nature-Flame platform's vent-free heating and flame presentation.
The concrete cast refractory logs reproduce recognizable birch wood-grain texture, bark character, coloration, and lighter birch-style markings. At 30 inches, this is the largest Highridge Birch log size documented in the supplied Nature-Flame range, which also includes 18" and 24" configurations.
Superior's Nature-Flame pan burner produces tall natural-yellow flames, random flame movement, and a flickering ember bed, while the wood-burning-style grate supports the appearance of a traditional wood fire.

Firebox Fit & Burner Compatibility
The 30-inch log-set size, the 24-inch burner requirement, and the usable firebox dimensions must all be checked independently before ordering.

Measure the usable firebox interior. Do not use the exterior fireplace, decorative opening, mantel, or surround as the determining measurement.
Do not select the 30" Nature-Flame configuration if the usable fireplace is smaller than any of the stated minimum dimensions.
Why Does the 30" Highridge Birch Use a 24" Burner?
Superior specifies the LNF30HB as a 30" log set paired with a 24" Nature-Flame burner. The published 30-inch log configuration does not call for a 30-inch burner.
This distinction is especially important when replacing an existing log set, selecting a new burner, or checking compatibility with an existing Nature-Flame system.

Key Highridge Birch & Nature-Flame Features
30" Birch-Style Presentation
The largest Highridge Birch log size documented in the supplied Nature-Flame range.
Concrete Cast Refractory Logs
Detailed birch-style wood grain, bark character, coloration, and distinctive markings.
Nature-Flame Pan Burner
The approved burner creates random flame movement and tall natural-yellow flames.
Flickering Ember Bed
The ember effect creates glow and visual depth beneath the larger birch arrangement.
99% Heating Efficiency
Nature-Flame models are heater rated at 99% heating efficiency.
Supplemental Heating
The system is intended for supplemental heating and should be installed and operated according to Superior instructions.
LNF30HB Highridge Birch Log Placement
The LNF30HB logs must be installed exactly as specified by Superior. They should not be modified or rearranged according to personal preference.
The supplied source notes that the 24" and 30" Highridge Birch sets use a dedicated placement sequence that differs from the 18" configuration. The instructions identify the proper positions for the rear log, right log, right-front log, middle crossover log, left-top log, and related components.
Do not alter the approved arrangement. Proper placement is required to maintain the intended flame pattern and operating characteristics. Do not place ember material over burner ports.
Fuel, Control & BTU Configuration
The LNF30HB uses the same documented 24-inch Nature-Flame burner size as the 24-inch Highridge Birch configuration, which is why the supplied BTU ranges are the same for those two log sizes.
Natural Gas
Natural Gas configurations operate from 28,000 to 39,000 BTU/hr.
Propane / LP
Propane/LP configurations operate from 25,000 to 36,000 BTU/hr.
Millivolt Control
The millivolt Nature-Flame configuration is remote ready for compatible optional remote and wall-mounted controls.
Electronic Control
The electronic configuration includes the EcoFlow Touch Screen Multi-Function Remote with Manual and Thermostat operating modes, On/Off control, and three flame-height settings.
Select the burner for the actual fuel supply. If the available fuel type is uncertain, verify it before ordering the Nature-Flame burner configuration.

Vent-Free & Vented Installation
Vent-Free Operation
The Superior Nature-Flame series is designed for vent-free operation.
During approved vent-free operation, the appliance does not rely on conventional chimney venting. Adequate combustion and ventilation air must still be provided according to the applicable installation manual.
Vented Operation
The Nature-Flame series is also listed for qualifying vented fireplace applications.
For an applicable vented installation, a damper clamp is required to maintain the necessary permanent flue opening. The damper clamp is sold separately.
Local requirements may apply. Vent-free appliances may be subject to state, local, or installation-specific requirements. Confirm that the intended installation is permitted.
Compatible Controls
Control compatibility depends on the selected Nature-Flame burner and control configuration. Confirm compatibility before ordering optional controls.

Replacement Log Set Compatibility
Superior identifies the LNF30HB as a complete log set. It is not intended to be used as a collection of individual replacement logs for an unrelated log arrangement.
If replacing an existing set, confirm that the current burner is one of the approved Nature-Flame 24 models before ordering LNF30HB.
Qualified installation required: Installation and service must be performed by a qualified installer, service agency, or gas supplier as specified in Superior's installation documentation.
The fireplace must be off and cold before beginning log installation. Logs can remain hot after operation, so allow adequate cooling time before handling.
Heating performance and flame appearance can vary with elevation, fuel type, home design and insulation, ceiling height, accessories, and appliance location.

Manufacturer Manuals & Technical Resources
Review the documentation applicable to the selected burner, fuel, and control configuration before installation, operation, service, or log placement.
The Superior Highridge Birch 30" LNF30HB is suited to larger qualifying fireplaces where a wide birch-style log presentation is desired while using Superior's approved 24-inch Nature-Flame burner platform.
The most important sizing distinction is that the 30" designation refers to the log set, while the compatible burner size is 24". The usable firebox must provide at least 33" front width, 25" rear width, 19" height, and 15" depth.
Do not select the product by log size alone. Burner model, fuel configuration, control type, fireplace dimensions, venting application, log placement, combustion and ventilation requirements, and qualified installation should all be verified before purchase.

Great customer service for hard to get refractory brick back
I was able to get a Novus 33 in brick refractory back for my NG Novus fireplace insert. Novus is a high demand item and Flame authority was only supplier without a huge delay from manufacturer. I recommend them for all fireplace needs.

Product is great, free shipping was good, and unpacking and installing it was easy. Customer support was great too, both with the sales and shipping carrier. After much research…the Modern Flames Redstone is the one.

Beautiful Mantel
The mantel required a little bit of sanding and prep before painting, but was good quality. Flame Authority did an excellent job shipping and it arrived by freight in perfect condition.
The mantel assembled well. I ended up using some construction adhesive to glue the legs on to make it a little more sturdy. I cut pocket holes in the top to attach it to the wall.
Very happy with our purchase!

Blaze Pro Portable Grill
I shopped for a grill for two people. I want it to last for ten years or more. I want it to get really hot for grilling steaks after they have been cooled sous vide. I want it to be useful also for lower temp cooking. This Blaze grill is perfect for me and my wife. Our purchase through Flame Authority was completed with no problems. I am totally satisfied with this grill and highly recommend it for anyone with similar needs.

Great heating stove
I bought the stove couple weeks ago and ended up having a chance running it a few days I am very pleased with the outcome of the amount of heat it gets out also with the amount of hours it burns at least eight hours. I would recommend this for anyone who is looking for hours of heat output. At first when I bought it I didn’t quite know if mine hopes will be for filled but now they are happy with it. I would recommend this to anyone as a trusted tester of it I am very pleased of the outcome it rains.!

Great Customer Service
I believe it was David Novak that helped me. Someone ALWAYS answered the phone and located this burner when I couldn't find it anywhere else. It almost seemed too good to be true. But it wasn't. The burner is now nestled in my new outdoor kitchen and am very pleased.
