Product detail
Upgrade your fireplace opening or built in wall design with the Modern Flames Redstone 30 Inch Built In Electric Fireplace Insert. Designed for homeowners who want the look and comfort of a traditional fireplace without the smoke, ash, venting, or wood burning maintenance, the Redstone RS 3021 delivers realistic flame visuals, supplemental heat, and a clean finished appearance.
With its compact 30 inch size, glowing driftwood log set, acrylic crystal ember bed, customizable flame presentation, and built in heater, this electric fireplace insert is ideal for living rooms, bedrooms, offices, condos, apartments, smaller fireplace openings, and renovation projects.
The Redstone 30 inch fireplace insert is designed to help modernize older wood burning fireplace spaces. It can be installed into many existing fireplace openings or placed into a properly framed wall cavity for a built in, flush mount appearance.
This makes it a strong option for homeowners who want the classic presence of a fireplace with the simplicity of electric operation. No wood storage, no gas line, no ash cleanup, and no traditional venting requirements.
The Redstone RS 3021 uses Modern Flames Hybrid FX Flame Technology to create a more vivid and dimensional electric fireplace experience. The Redstone Series includes customizable flame colors, adjustable flame speed, ember bed lighting, and down lighting so the fireplace can match your room, mood, and season.
Keep the flame warm and traditional for everyday comfort, or adjust the lighting effects for a more modern fireplace presentation.
The Redstone 30 inch fireplace includes both an LED lighted driftwood log set and acrylic crystal media. This gives the fireplace a layered look that blends traditional warmth with modern visual detail.
The driftwood logs create a familiar firebox feel, while the acrylic crystal ember bed adds brightness, depth, and a more refined electric fireplace appearance.
This electric fireplace insert includes a 5,000 BTU heater for supplemental warmth. The flame effect can also operate with or without heat, allowing you to enjoy the look and ambiance of the fireplace throughout every season.
Use the heat function during cooler months, or turn on the flames by themselves when you simply want the visual comfort of a fire.
The Redstone RS 3021 is designed for built in, flush mount, or insert style installation. It can be installed into an existing fireplace opening or placed into a properly framed wall opening with the required depth.
The unit can plug into a standard 120V outlet and is also hardwire ready for projects where a cleaner finished installation is preferred. Professional installation is recommended for built in or hardwired applications.
The Modern Flames Redstone 30 Inch Built In Electric Fireplace Insert is a strong choice for homeowners who want a realistic fireplace upgrade in a compact, versatile format. It combines the classic look of a traditional firebox with electric convenience, customizable flame visuals, included media options, and supplemental heat.
For anyone refreshing an older fireplace opening or creating a new built in fireplace feature, the Redstone RS 3021 delivers warmth, ambiance, and a clean finished look without the maintenance of a wood or gas fireplace.
