Modern Flames Redstone 42" Built-in Electric Fireplace Insert

Hybrid-FX™ Flame Technology

• High-intensity RGB LEDs create ultra-realistic, independently controlled flames, ember bed, and downlight colors — giving your room the warmth and ambiance of a real fire without any of the mess.

10 Customizable Color Options

• Choose from 10 flame, 10 ember bed, and 10 downlight color combinations so you can perfectly match your mood, décor, or season at the touch of a button.

Heats Up to 400 Sq. Ft.

• With 5,000 BTUs and two heat settings, this insert efficiently warms small to mid-sized rooms, making it an ideal zone-heating solution that can lower your overall energy costs.

Safe to Mount TV Above

• Forward heat projection means no heat rises toward your TV or mantel, so you can confidently install this fireplace beneath your television without worry.

No Venting, Easy DIY Install

• Designed to slide into existing zero-clearance fireplaces or a standard 10-inch wall cavity, this insert requires no venting, no gas lines, and no special construction — just plug in and enjoy.

Flame-Only Year-Round Mode

• Run the flame display without any heat output, so you can enjoy the cozy ambiance of a flickering fire even during warm summer months.

Flames So Real, You'll Do a Double Take

• Powered by Hybrid-FX™ Flame Technology, the Redstone uses high-intensity RGB LEDs to produce a fire display that genuinely rivals the look of a real wood-burning hearth. With 10 flame, 10 ember bed, and 10 downlight color options all independently controlled, you can dial in exactly the right mood — from a warm golden glow on a cozy evening to a dramatic, vivid display that becomes the focal point of any room.

Warmth Where You Need It, When You Need It

• The Redstone delivers 5,000 BTUs of supplemental heat, efficiently warming up to 400 square feet without cranking up your central heating system. Choose between two heat settings or let the built-in thermostat automatically maintain your ideal temperature — so your living room, bedroom, or home office stays perfectly comfortable all season long, without the waste of heating rooms you're not using.

Install It Anywhere — No Gas, No Venting, No Contractor

• Unlike traditional fireplaces, the Redstone requires zero venting and zero gas lines, which means you're not locked into one spot in your home. Slide it into an existing zero-clearance fireplace or build it into any standard 10-inch wall cavity — it's a genuine DIY project that comes with trim kits and clear instructions included. Simply plug it into a dedicated 120V outlet and you're done.

Your TV Belongs Right Above It

• Most fireplaces and TVs don't mix — but the Redstone is specifically engineered with forward heat projection, meaning warm air flows outward into the room rather than rising upward. That makes it one of the rare electric fireplaces genuinely safe to mount a television above, giving you the sleek, modern media-wall look you've been envisioning without any risk to your electronics.
