Modern Flames Orion Slim Built-In / Wall-Mounted Electric Fireplace for 2x6 Walls

A Realistic Slim Built-In or Wall-Mounted Electric Fireplace for 2x6 Walls

The Modern Flames Orion Slim is a slim built-in or wall-mounted electric fireplace designed for projects that need realistic flames in a shallower wall profile. With its 6-5/16" depth, the Orion Slim can be recessed into a 2x6 wall for a clean built-in look or mounted directly on the wall for a streamlined installation.

At the center of the experience is HELIOVISION™ flame technology, which creates a layered flame effect that feels more dimensional than a standard linear electric fireplace. Version 2 builds on that foundation with improved display quality, smarter controls, and a more immersive overall presentation.

Who It's For

The Orion Slim is a strong fit for homeowners, designers, and contractors looking for a premium electric fireplace in projects where wall depth is limited. It works especially well in remodels, media walls, living rooms, bedrooms, and other spaces where a slimmer profile matters but you still want a realistic built-in fireplace appearance.

HELIOVISION™ Flame Realism with Orion V2 Upgrades

Orion Slim uses HELIOVISION™ virtual flame technology to produce layered, multi-dimensional flames with more depth than a standard 2D electric fireplace. With 18 flame display options, adjustable flame speed, multicolor ember bed lighting, and multicolor downlighting, you can tailor the look to your room and style.

Version 2 refines that experience with sharper contrast, deeper blacks, adaptive brightness, and an upgraded log presentation for a more immersive overall look.

Smart Control with Sound and Comfort Features

Control the fireplace using the included remote, integrated touch controls, or the Modern Flames mobile app. Orion Slim also includes ambient crackling fire sound, thermostat control, and timer settings for added convenience.

The built-in thermostat can be adjusted from 68°F to 88°F, while the timer can be set from 30 minutes to 8 hours. Flames can be enjoyed with or without heat, making the Orion Slim a flexible year-round feature.

Installation and Fit

One of the biggest advantages of the Orion Slim is its installation flexibility. It can be fully recessed into a 2x6 wall for a cleaner built-in appearance or mounted directly on the wall surface when full recessing is not the best fit for the project.

No venting is required. The unit can be hardwired for a clean built-in look or plugged into a compatible outlet. Orion Slim is available in 52", 60", 76", and 100" sizes to suit different spaces.

If you want a more finished media-wall look around the Orion Slim, you can pair it with the Modern Flames Allwood Fireplace Wall System for Orion Slim Electric Fireplace. This wall system is designed for the Orion Slim 60" and is available with or without the fireplace. It includes the main wall section assembly, ALLWOOD mantel, hardware, and user’s manual, and it is offered in Weathered Walnut, Coastal Sand, and Driftwood Gray finishes. If you want to extend the wall system on both sides of the main wall, two side walls must be added separately.

Orion V1 vs. Orion V2: What Changed?

V2 keeps V1’s HELIOVISION™ platform and adds a sharper display, the Modern Flames+ app with over-the-air flame updates, brighter lit logs and Bluetooth audio.

Orion Slim V2 is approved for outdoor installation. V1 is not. Modern Flames tested it for use under a patio cover, away from direct water contact and direct sunlight. The approval covers the built-in installation only, the patio roof overhang has to be at least 50% of the height measured from the bottom of the fireplace, the same 50% applies to the open distance at each side, and the base has to sit at least 2 inches above the floor. An uncovered deck or a pergola with open slats does not qualify. Orion Slim V2 can also be installed without a frame for a modern, clean-face look.
