Modern Flames Spectrum Slimline Built-in/Wall Mounted Electric Fireplace with Multicolor Flame and Ember Bed

Modern Flames Spectrum Slimline Built-In Linear Electric Fireplace is an improved version of the Spectrum electric fireplace! Featuring Hybrid-FX™ Flame Technology, twelve flame and ember bed colors, thermostat, remote, and timer, this fireplace has more color combinations and features than the original Spectrum in a slim package. Available in four sizes: 50" to 100" wide, this visually stunning fireplace is perfect for adding style, warmth, and ambiance to any room.

Spectrum Slimline electric fireplace is less than 5" deep and designed for wall mount or recessed installation. Wall mounting this fireplace is quite easy using the mounting brackets that come with it. Two people can do the job. Clean face or 2" x 4" installation may require a bit more work as hardwiring this fireplace requires a qualified electrician.

Modern Flames' Hybrid-FX™ Flame Technology is an enhanced version of their realistic award-winning flame technology. This new technology allows independent control of the flame and ember bed colors resulting in more color combinations and more vibrant flames. A large viewing area with a sleek 5/8" trim and colorful display, combined with log or glass media, both come with the fireplace, makes this fireplace an eye-catching wall accent.

Spectrum Slimline is more than just a decorative piece as it can easily heat up a small room or provide supplementary heat to a large room. At its highest setting, it is capable of producing 5,000 BTUs of heat, which is good enough to heat a room up to 450 square feet. Or, set it to a particular temperature from 68 to 88 °F using the touch control panel or remote included with the fireplace.

Modern Flames Spectrum Slimline is available in four sizes, 50", 60", 74", and 100" making it an excellent fire feature for any residential or commercial space.

        Perfect fireplace for our short term rental!

        We bought two of these fireplaces in different sizes to install in our vacation house that we also Airbnb part of the year. The fireplaces look amazing!! They gave our vacation home a cozy warm feel and made our Airbnb listing really stand out! Money well spent.

        Very nice!

        We did test it to see how the heat runs. Hoping this will help warm up the room. It’s the main reason why we got it
