What Makes This Unit Stand Out
DESCRIPTION & FEATURES
The Modern Flames Orion Slim 52" is the most compact model in the Orion Slim series, making it ideal for bedrooms, offices, home theaters, and smaller living spaces where you want a dramatic flame display without overwhelming the room. At 52 inches wide and only 6-5/16" deep, the OR52-SLIM slides into a standard 2x6 wall for a clean, flush installation — or mount it directly on any wall using the included bracket.
The Orion Slim 52" features Modern Flames’ Heliovision™ flame technology, which produces the most realistic virtual flame effect available in any electric fireplace. Choose from three flame patterns (wood-burning with sparks, gas flame, or hybrid), six flame colors, adjustable flame speed, and multi-color ember bed and downlighting to create exactly the ambiance you want. An ambient crackling sound system completes the experience.
Control everything from the included remote, the built-in touch panel, or the Modern Flames WiFi app on your phone. The app also provides Alexa and Google Home integration, weekly scheduling, and thermostat control for the built-in 5,000 BTU heater. The OR52-SLIM comes with a western driftwood log set and black reflective crushed glass media included.
