The Modern Flames electric fireplace lineup covers more installation scenarios than almost any other brand in the premium built-in category. The Modern Flames Orion series alone spans three distinct formats: Multi, Slim, and Traditional, each designed for a different wall type or opening configuration. Add the Landscape Pro series for outdoor-rated installations, the Spectrum Slimline for ultra-thin walls, and the Redstone for traditional insert replacements, and you have a lineup that covers entry-level inserts through large-format feature walls. This guide walks through every series, explains what each one is built for, and helps you identify the right model for your project.
Modern Flames is a US-based electric fireplace manufacturer known for its focus on flame realism, smart connectivity, and installation flexibility. The brand's products are built around their proprietary virtual flame technology, which uses a combination of LED lighting, reflective surfaces, and fuel bed design to produce flame effects that read more like a real fire than the flat projections used in commodity electric fireplaces. Most Modern Flames products support Wi-Fi control through the Modern Flames app, Alexa, and Google Home integration, and include features like adjustable flame speed, multi-color ember beds, downlighting, and integrated crackling sound. Products are available through authorized dealers in the US and Canada.
The Orion series is Modern Flames' flagship product line. All three Orion variants share the same advanced flame technology and smart home connectivity, but are designed for different installation types and wall constructions.
The Orion Multi is available from $4,799 and is designed for both built-in recessed installation and wall-mounted applications. It is available in 52", 60", 76", 100", and 120" widths, covering everything from a standard living room feature wall to a large commercial installation. The Multi format supports a 3-sided viewing configuration with add-on options, making it suitable for peninsula and see-through installations where a standard single-face linear would not work. Heat output ranges from 5,000 to 10,000 BTU depending on size and configuration, and the unit supports both plug-in and hardwire installation. Wi-Fi control, crackling sound, multi-color ember bed, and downlighting are all included.
The Orion Slim starts at $4,279 and is engineered for installations into 2x6 stud walls, with a depth that allows a fully recessed, flush-to-wall installation without custom framing. It is available from 50" through large-format sizes and shares the Orion platform's flame technology, Wi-Fi connectivity, crackling sound, and ember bed features. If your project involves a new-build or renovation with 2x6 framing, the Slim is the cleanest installation path in the lineup.
The Orion Traditional starts at $2,149 and applies the Orion flame technology to a smaller, square or traditional firebox format. It is available in sizes from under 30" through the 40"-49" range, making it the right choice when the installation calls for a traditional firebox shape rather than a wide linear format. Like the other Orion models, it includes Wi-Fi control, crackling sound, and multi-color flame options. The lower price point also makes it the entry point into the Orion platform for buyers working with standard fireplace opening dimensions.
The Landscape Pro series is Modern Flames' outdoor-capable product line. Both the Landscape Pro Multi and the Landscape Pro Slim are rated for covered outdoor installations, making them appropriate for screened porches, covered patios, and exterior entertainment walls built to accept a recessed electric fireplace. They share the same multi-color flame system and Wi-Fi connectivity as the rest of the lineup, but are built to operate in temperature ranges and humidity levels that indoor-only units cannot handle.
The Landscape Pro Multi starts at $2,779 and is available in 42" through 78" widths. Like the Orion Multi, it supports 3-sided viewing configurations with add-on components, which makes it the right choice when the outdoor installation calls for a peninsula or see-through layout. Heat output reaches 10,000 BTU on larger units, and the unit supports Wi-Fi scheduling, remote control, and Alexa or Google Home integration. A wall mount cabinet accessory is available for installations where a recessed wall cavity is not feasible.
The Landscape Pro Slim starts at $2,299 and is the ultra-thin option in the outdoor-rated category. Its 5.5" depth allows it to be installed into a 2x6 wall cavity flush to the finished surface, which is the cleanest integration for new outdoor structures built with standard framing. It is available in widths from 40" through the 80"+ range. Heat output is 5,000 BTU and the unit includes thermostat control, sleep timer, and Wi-Fi connectivity. If the outdoor installation has standard 2x6 framing, the LPS is the lower-effort, lower-cost path relative to the LPM.
The Modern Flames Spectrum Slimline starts at $1,599 and is designed for the thinnest possible wall installations. At under 5" in depth, it fits into a standard 2x4 or 2x6 wall without custom framing. It is available from 50" through large-format widths and supports both recessed and wall-mounted configurations. Heat output is 5,000 BTU with a fan-forced coil heater, and the unit includes Wi-Fi control, multi-color flame, remote control, and sleep timer. The Spectrum Slimline does not include crackling sound, which is a feature reserved for the Orion series. For buyers who need a large-format linear fireplace in an existing wall with minimal construction impact, the Spectrum Slimline is the practical choice.
The Redstone series covers the traditional built-in insert category, with sizes from 26" through 54" and prices from $999 to $3,149. The Redstone is designed to drop into a standard firebox opening or a custom-framed cavity and produces a traditional log-and-ember flame effect rather than a wide linear format. It uses a fan-forced coil heater rated at 5,000 BTU and includes multi-color flame, remote control, and plug-in operation. The Redstone does not include Wi-Fi or crackling sound. It is the entry point into the Modern Flames lineup for buyers replacing a gas insert or installing a traditional-style electric firebox. Available models include the Redstone 30" ($1,179), Redstone 36" ($1,499), Redstone 42" ($1,699), and Redstone 54" ($3,149).
The Modern Flames Challenger starts at $949 and is the entry-level option in the linear built-in category. Available in 50" and 60" widths, it offers a flush-mount recessed installation at a price point significantly below the Orion and Landscape Pro series. It includes multi-color flame and remote control but does not include Wi-Fi, crackling sound, or the advanced virtual flame technology of the Orion platform. For buyers who want a Modern Flames linear fireplace at the lowest available price, the Challenger is the starting point.
The clearest decision point in the lineup is installation type. If the project involves a traditional firebox opening or mantel surround, the Redstone is built for that. If the project calls for a wide linear built-in in a standard interior wall, the Spectrum Slimline at 2x4 depth or the Orion Slim at 2x6 depth are the practical options. If outdoor rating matters, the Landscape Pro series is the only option. If 3-sided or see-through viewing is part of the design, the Orion Multi or Landscape Pro Multi are the relevant products. For buyers who want the most complete smart home integration and the most realistic flame effect regardless of format, the Orion series is where Modern Flames' most advanced technology is concentrated.
The Orion Multi and Landscape Pro Slim are consistently among the most specified Modern Flames products. The Orion Multi is the most flexible in format, supporting single-face, 3-sided, and wall-mount configurations across a wide range of sizes. The Landscape Pro Slim is the most popular for covered outdoor installations due to its shallow depth and clean flush-mount integration into standard 2x6 framing.
No. The Orion series is rated for indoor use only. For covered outdoor installations, the Landscape Pro Multi and Landscape Pro Slim are the appropriate Modern Flames products. These are specifically rated for outdoor environments including covered patios, screened porches, and exterior entertainment walls. Never install an indoor-rated electric fireplace in an outdoor location.
Modern Flames' virtual flame system uses a combination of LEDs, reflective surfaces, and a precisely engineered fuel bed to produce a flame effect that reads more realistically than projection-based systems. The flame is three-dimensional and responds to settings like color, speed, and intensity through the app. The result is a flame that holds up under normal viewing conditions better than most electric fireplace designs in the same price range.
The key differences are viewing format, depth, and heat output. The Landscape Pro Multi supports a 3-sided viewing configuration and outputs up to 10,000 BTU on larger units. The Landscape Pro Slim is a single-face linear unit with a 5.5" depth suited to 2x6 wall installations, outputting 5,000 BTU. If the installation needs 3-sided viewing or higher heat output, choose the Multi. If the priority is shallow depth and a clean flush-mount finish in standard framing, choose the Slim.
No. Crackling sound is a feature of the Orion series and is not included in the Spectrum Slimline. The Spectrum Slimline includes multi-color flame, Wi-Fi control, remote, and sleep timer. If integrated crackling sound is a requirement, the Orion Multi, Orion Slim, or Orion Traditional are the relevant products from the Modern Flames lineup.
Yes. All Modern Flames electric fireplaces support independent flame and heat operation. You can run the flame effect at any time of year without engaging the heater. This is controlled through the app, the wall control, or the remote depending on the model. Running the flame only draws a small fraction of the power compared to running heat, making year-round flame use practical in any climate.
The Orion Multi is available in 52", 60", 76", 100", and 120" widths. The 52" and 60" models are the most common for residential feature walls, while the 76", 100", and 120" models are frequently specified in commercial environments and large open-plan residential projects. All sizes share the same flame technology and smart connectivity features, with heat output scaling by size.
The Orion Slim is designed for 2x6 wall construction, which provides approximately 5.5" of cavity depth. It achieves a fully flush installation in a standard 2x6 stud wall without requiring custom framing or deeper wall construction. This is the reason the Slim is specified in new builds and renovations where the framing plan already includes 2x6 exterior or feature walls.
No. The Redstone series does not include Wi-Fi or app control. It uses a standard remote control and manual controls on the unit. If Wi-Fi connectivity and smart home integration are priorities, the Orion Traditional is the appropriate entry point into smart connectivity in the Modern Flames lineup. The Redstone is optimized for price and simplicity rather than feature depth.
