Frequently Asked Questions

  • Yes, the Sierra Flame 40-inch (WM-FML-34-4023-STL) is designed for both installation methods. Heat is emitted through the face below the glass viewing area, allowing for a flush/recessed installation, and if recessing is not an option, it can also be surface-mounted on the wall using the included mounting brackets. This makes it a practical choice for apartments or spaces where wall construction is not possible.

  • The Sierra Flame 40-inch linear electric fireplace features an integrated 4,800 BTU heater capable of zone heating approximately 400–500 square feet. It is designed as a supplemental heat source, not a primary one, and the heater can be turned off entirely so the flame display can be enjoyed year-round without producing heat.

  • The unit features Sierra Flame's Fire & Ice flame presentation with three color LED light strips, allowing you to choose from red, yellow, orange, and rose-colored flames with a click of the remote. It also includes 13-color surround back-lighting behind the steel surround, which can be mixed with flame colors independently for a virtually limitless combination of visual effects.

  • The overall surround measures 40 inches wide by 22.5 inches high, with a glass viewing opening of 31.5 inches wide by 10 inches high and a unit depth of approximately 6.125 inches. The package includes the charcoal steel surround, clear crystal ember decorative fire glass media, a mounting plate, and a multi-function remote control; additional media options are available for separate purchase.

  • Sierra Flame warrants the electric fireplace to be free from manufacturing and material defects for a period of two years from the date of first purchase, covering parts only (labor is not included). The unit operates on a standard 120V outlet, so no special wiring or dedicated circuit is required for a straightforward plug-in installation.
