How is the Modern Flames Redstone 36" installed, and can I do it myself?

The Redstone 36" (RS-3626) is designed for two installation methods: it can slide directly into an existing zero-clearance wood-burning fireplace, or it can be recessed into a wall with at least 10 inches of depth for a flush-mounted look. No venting, chimney, or gas lines are required, and the unit comes with DIY-friendly step-by-step installation instructions. It plugs into a standard 120V outlet, though a hardwire option is also available for a cleaner appearance.

How much heat does the Redstone 36" produce, and what size room can it heat?

The Redstone 36" includes a built-in 5,000 BTU heater with two heat settings — 750W on low and 1,465W on high — capable of providing supplemental zone heating for rooms up to 400–500 square feet. A built-in thermostat lets you set and maintain temperatures between 68°F and 88°F automatically. The flame effect can also run independently without heat, making it usable year-round purely for ambiance.

What flame and color customization options does the Redstone 36" offer?

The Redstone 36" features Modern Flames' Hybrid-FX™ flame technology, which independently controls the flame, ember bed, and downlight colors — each offering 10 unique RGB color options for a total of highly personalized combinations. Flame brightness, height, and intensity are all adjustable, and the unit comes standard with both acrylic crystal media and a realistic driftwood log set. Optional cannonball media is also available for an alternative aesthetic.

Is it safe to mount a TV above the Modern Flames Redstone 36" electric fireplace?

Yes — the Redstone 36" is specifically engineered to be safe for TV installation above it because it produces no upward heat, directing warmth outward into the room rather than upward toward electronics. This makes it an excellent choice for media wall builds, provided clearances outlined in the installation manual are followed. The clean-face flush-mount design further supports a polished, integrated media wall look.

What warranty does the Modern Flames Redstone 36" come with?

The Modern Flames Redstone 36" comes with a 5-year limited manufacturer's warranty if the product is registered with Modern Flames within 30 days of purchase, or a 2-year warranty if it is not registered within that window. The warranty covers defects in materials and workmanship, and Modern Flames may repair, replace, or refund the purchase price for covered defects. Normal wear and tear, improper installation, and environmental damage are excluded from coverage.

A Fire So Real, You'll Do a Double Take

The Redstone's Hybrid-FX™ Flame Technology produces a layered, ultra-realistic flame display unlike anything a standard electric fireplace can achieve. With 10 color combinations across the flame, ember bed, and downlight — each controlled independently — you can dial in a fire that perfectly matches your room's mood. Whether you want a dramatic amber blaze or a cool, modern blue glow, this fireplace makes it happen at the touch of a button.

Cozy Warmth, Exactly Where You Need It

The Redstone delivers up to 5,000 BTUs of efficient supplemental heat, capable of warming rooms up to 400 square feet — perfect for a living room, bedroom, or home office. Choose between two heat settings to match the conditions, and let the built-in variable thermostat take over from there, automatically maintaining your ideal temperature without constant adjusting. It's zone heating done right: warm the room you're in and stop paying to heat the rooms you're not.

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

Because the Redstone requires no venting and no gas line, you're not limited to rooms with an existing chimney or exterior wall — place it virtually anywhere in your home. The plug-in design and DIY-friendly installation mean most homeowners can complete the setup with minimal tools and no contractors required. Whether you're updating an old, non-functioning fireplace or adding one to a new build, the Redstone fits both built-in and clean face configurations with ease.

Mount Your TV Above It — Seriously

Most fireplaces and TVs don't mix, but the Redstone was engineered specifically with this combination in mind. Because it emits zero heat upward, there's no risk of heat damage to your television or any electronics mounted above — giving you the sleek, magazine-worthy media wall look you've always wanted. It's one of the most practical and distinctive features of this model, solving a real design problem that stops most homeowners from combining these two focal points.
