Frequently Asked Questions

  • The Redstone 30" can be installed two ways: slide it directly into an existing zero-clearance wood-burning fireplace, or recess it into a wall with at least 10 inches of depth for a flush-mount look. It plugs into a standard 120-volt outlet, making it a true DIY-friendly install — reviewers frequently note it is easier to install than expected, with no need for a professional. It is also hardwire-ready if you prefer to conceal the power cord.

  • The Redstone 30" includes a 5,000 BTU heater capable of warming spaces up to 400 square feet, with two power settings — 1,465 watts on high and 750 watts on low. The thermostat can be set anywhere from 68°F to 88°F using the touchscreen panel or included remote. Importantly, the flame display can be enjoyed with or without the heater running, making it suitable for year-round ambiance.

  • The Redstone 30" uses proprietary Hybrid-FX™ flame technology, which independently controls the flame, ember bed, and downlight colors for a highly realistic effect. It offers 10 unique flame color options with RGB LED up-lighting and down-lighting, plus adjustable flame speed and brightness. Both acrylic crystal media and hand-painted driftwood logs are included as standard media, giving the display a natural, layered look.

  • The Redstone 30" comes with a 5-year limited 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. If a defect in materials or workmanship is found during the warranty period, Modern Flames may repair, replace, or refund the purchase price. The warranty is only valid when the unit is purchased through an authorized retailer and installed according to Modern Flames' guidelines.

  • The Redstone 30" comes standard with a 1-5/8" finish trim kit (measuring approximately 32"W x 21"H), which gives the unit a clean picture-frame appearance after installation. A narrower 5/8" slide-in trim is also included for zero-clearance fireplace installs. If you need a wider surround to cover a larger fireplace opening, optional extra-wide trim kits and insert surround kits are available separately in 4", 5", 6", and 8" sizes.
