Product detail
Bring modern fireplace style, customizable flame visuals, and supplemental warmth into your home with the Modern Flames Spectrum Slimline Built In Electric Fireplace. Designed with a clean linear profile and slim installation depth, the Spectrum Slimline is ideal for living rooms, media walls, bedrooms, condos, apartments, offices, and contemporary entertainment spaces.
Available in multiple sizes, this electric fireplace gives homeowners the flexibility to create a polished built in fireplace feature without the venting, gas lines, ash, smoke, or maintenance of a traditional fireplace.
The Spectrum Slimline is designed for a sleek, modern look with a high viewing area and minimal trim. Its linear shape makes it a strong choice for fireplace feature walls, media walls, and spaces where the fireplace needs to feel architectural without overpowering the room.
Whether installed beneath a mounted TV, inside a recessed wall opening, or as a wall mounted fireplace, the Spectrum Slimline creates a clean focal point that adds warmth, depth, and visual balance to the space.
Modern Flames equips the Spectrum Slimline with Hybrid FX Flame Technology for a vibrant, customizable electric fireplace experience. The fireplace includes independently controlled flame and ember bed colors, variable flame speed, and adjustable brightness so you can create the exact mood you want.
Choose a traditional warm flame for everyday comfort or adjust the colors for a more modern and dramatic room atmosphere.
The Spectrum Slimline includes both a hand painted Canyon Driftwood log set and acrylic crystal media, giving you two design options for the ember bed. Use the driftwood logs for a warmer, more natural fireplace appearance, or use the crystal media for a cleaner contemporary look.
This built in electric fireplace includes a 5,000 BTU heater for supplemental warmth in your room. The flame effect can also operate without heat, allowing you to enjoy the look and ambiance of the fireplace throughout every season.
Use it for added comfort during colder months, or turn on the flame display by itself when you simply want the relaxing visual presence of a modern fireplace.
The Spectrum Slimline is designed for flexible installation and can be installed as a recessed built in electric fireplace or as a wall mounted fireplace. Its slim design makes it a strong fit for modern wall applications where depth, clean lines, and visual simplicity matter.
The Modern Flames Spectrum Slimline Built In Electric Fireplace is a strong choice for homeowners who want modern fireplace design with flexible installation and customizable ambiance. Its slim profile, high viewing area, realistic media options, and adjustable flame display make it easy to create a premium fireplace feature in almost any indoor space.
For anyone building a fireplace wall, upgrading a media room, or adding a clean electric fireplace to a modern home, the Spectrum Slimline delivers style, comfort, and everyday convenience in one refined fireplace system.
