The Modern Flames Redstone 30 (RS-3021) is a traditional-look electric firebox that either slides into an existing fireplace or builds flush into a new framed wall. It brings a log fire picture and real supplemental heat to a fireplace you no longer burn, or to a wall that never had one.
Ten flame colors and ten ember bed colors, a flame brightness control and four flame speeds are run from the touch panel or the included remote. Driftwood logs and glacier crystals come in the box, along with a second, thicker trim.

- Required: a dedicated 120V 15 A circuit; for an insert, an outlet inside the existing fireplace wired by an electrician

Installation Notes
For a built-in, frame a 28-1/4 x 18-3/4 x 10 in. D finished opening and keep 11.8 in. from the glass to a mantel. For an insert, clear the existing fireplace, add an outlet inside it, then slide the unit in; it is held by gravity and friction. Never use an extension cord. Electric fireplaces need no gas line or venting, which makes them one of the simplest fireplace options for New York City apartments and co-ops, subject to building and board approval for any electrical work. Book a design consultation to plan an insert or a new built-in wall.
