Remii 45" Wall Mount Xtraslim Electric Fireplace WM-SLIM-45

Product overview

The Remii WM-SLIM is a 45-inch electric fireplace only about 4 inches deep, slim enough to hang on the wall like a picture or to recess into a standard 2×4 wall. Its full-frame viewing area keeps the face clean and modern, finished with a black powder-coated surround.

Flames glow in yellow, orange and red with five settings in each color, and the ember bed lights up in 10 colors or cycles through them all. Clear glass diamonds catch the light, and three flame speeds let you choose a slow flicker or a lively fire.

Heat is easy to manage. Set the room temperature you want, use the shut-off timer, or run the fireplace from your phone with the Smart Life app. The flames run without heat for year-round ambiance, and it plugs into a standard 120-volt outlet. It is made for indoor rooms, at home or in a commercial space.

Installation and safety notes

Keep furniture, curtains, bedding and other combustibles at least 3 feet (0.9 m) from the front, sides and back, and choose a dry spot. The fireplace is for indoor use only and must not be installed where water is used, such as a bathroom, kitchen or pool area. It works best in rooms between 41°F and 95°F (5–35°C).

For a wall mount, level the hanger, check the wall for wiring and pipes, drill at least 8 holes (8 mm wide, 40 mm deep), fit the wall plugs, fasten the hanger, hang the fireplace and secure it with the safety screw. For a recessed install, frame the opening with at least 1/4" (6 mm) around the unit, remove the glass and inner side panels, fasten the fireplace in the opening and refit the panels, media and glass.
