Frequently Asked Questions

  • 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.

  • 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.

  • 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.

  • 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.

  • 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.
