Modern Flames Redstone 36" Built-in Electric Fireplace Insert with Trim, Multicolor Flame, Ember Bed and Downlight

Modern Flames Redstone Built-In Electric Fireplace is a modern fireplace insert with a traditional look! Featuring Hybrid-FX™ Flame Technology to independently control the flame, ember bed, and downlight colors, thermostat, remote, and timer, this fireplace is perfect for adding style, warmth, and ambiance to any room.

Redstone looks like a real traditional fireplace without the drawbacks. This 36" wide fireplace comes with two trims. Designed for easy installation, just slide it in an existing zero clearance fireplace, and add the trim for a perfect finish. It can also be installed on any wall with 10" depth. Installing this fireplace can be a DIY job.

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 tall viewing area with a colorful display, combined with log and glass media, both come with the fireplace, makes this fireplace a stunning wall accent. Cannon Balls are optional decorative media for those who want a different look.

Redstone 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 400 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 Redstone is an excellent upgrade option for an existing wood-burning fireplace in any residential or commercial space.

This fireplace is also available in other sizes: Modern Flames Redstone Series Collection

What's Included: Electric Fireplace, Remote Control, Glass Media, Log Set, Trim Kits, and User's Manual

          Classy and warmth = this insert!

          Quick delivery, fairly easy installation, and lovely product (which has color options) are a few reasons to order this insert. Our other insert was open, but this ones gives a clean appearance and more modern vibes. LIVE!!

          Modern Flames Redstone 36" Built-in Electric Fireplace Insert (RS-3626)

          Shipped quickly and was well packaged. Well made and very easy install for a DIY project. More options to mix trim sizes would improve fitment when installing as an insert. Still a great product!
