Product detail
Upgrade your home with the warmth, style, and convenience of the Modern Flames Redstone 42 Inch Built In Electric Fireplace Insert. Designed for built in applications and existing fireplace openings, the Redstone RS 4229 gives homeowners the look of a traditional fireplace with the clean operation of modern electric technology.
With its realistic flame display, glowing log set, crystal ember bed, and supplemental heat, this 42 inch electric fireplace insert is ideal for living rooms, bedrooms, media rooms, offices, condos, and home renovation projects where a gas or wood burning fireplace is not practical.
The Redstone 42 inch fireplace is designed to bring new life to older fireplace spaces. It can slide into an existing zero clearance wood burning fireplace or be installed into a built in wall application with the proper framing depth. This makes it a strong choice for homeowners who want to replace ash, smoke, wood storage, and maintenance with a cleaner electric fireplace solution.
The finished look feels classic, warm, and familiar, while the electric operation makes it easier to use every day.
The Redstone RS 4229 uses Modern Flames Hybrid FX Flame Technology to create a more vivid and realistic fireplace experience. With 10 flame color options, adjustable flame speed, ember bed lighting, and down lighting, you can customize the fireplace to match your room, mood, or season.
Keep the flame soft and traditional for a cozy evening, or adjust the colors and brightness for a more modern visual effect.
This built in electric fireplace includes a 5,000 BTU heater for supplemental warmth in spaces up to approximately 400 square feet. The flame effect can also operate without heat, allowing you to enjoy the ambiance of the fireplace throughout the year.
Use the heater during colder months, or turn on the flame display by itself when you simply want the relaxing visual presence of a fire.
The Redstone 42 inch fireplace is designed for built in, flush mount, or insert style installation. It can be installed into a properly framed wall opening or used to modernize an existing fireplace opening. The unit plugs into a standard 120V outlet and should be installed according to the owner’s manual and local electrical requirements.
The Modern Flames Redstone 42 Inch Built In Electric Fireplace Insert is a strong choice for homeowners who want the comfort and character of a traditional fireplace with the simplicity of electric operation. It delivers realistic flames, customizable lighting, supplemental heat, and a clean built in look without venting, gas lines, or wood burning maintenance.
For anyone refreshing an old fireplace or creating a new built in fireplace feature, the Redstone RS 4229 offers a balanced combination of warmth, convenience, and timeless fireplace style.
