How difficult is it to install the Modern Flames Redstone 54-inch electric fireplace, and does it require an electrician?

Installation is designed to be a straightforward DIY project — the unit can slide directly into an existing zero-clearance wood-burning fireplace, or it can be recessed into a wall that has at least 10 to 12 inches of depth for a flush-mount look. It plugs into a standard 120-volt outlet, so no special wiring or electrician is required. Modern Flames includes easy-to-follow DIY installation instructions along with finish trim kits to create a clean, polished result.

What flame customization options does the Modern Flames Redstone 54-inch offer?

The Redstone 54-inch uses Modern Flames' Hybrid-FX™ flame technology, which independently controls the flame color, ember bed lighting, and downlighting using ultra-bright RGB LEDs — giving you 10 unique flame colors to choose from. Flame height, intensity, and motor speed are all variable, letting you fine-tune the look to your preference. Both acrylic crystal media and a detailed driftwood log set are included standard, so you can switch between a contemporary or traditional aesthetic.

What is the warranty on the Modern Flames Redstone 54-inch electric fireplace?

Modern Flames offers a 5-year limited warranty if you register the product with the manufacturer within 30 days of purchase, or a 2-year limited warranty if registration is not completed in that window. If a defect is found, Modern Flames may repair, replace, or refund the purchase price at their discretion. The warranty does not cover normal wear and tear, damage from improper installation or misuse, or environmental damage such as floods or storms.

Can the Modern Flames Redstone 54-inch insert fit into an existing wood-burning masonry fireplace?

Yes — the Redstone 54-inch is specifically designed as an excellent retrofit option for existing wood-burning or zero-clearance fireplaces, and Modern Flames considers the Redstone Series the best choice for that application. You simply slide the unit into the existing opening and plug it into a standard outlet; no venting, gas lines, or chimney work is needed. Two trim kit sizes (5/8" and 1-5/8") are included with the unit to ensure a finished, gap-free appearance around the insert.
