Sold and installed from our Stevens Point showroom · SKU NEFL42AS
A fireplace that fits inside a standard wall—no gas line, no venting, no bumped-out framing. Quick Facts • Heating Capacity: 150–250 sq ft • Viewing Area: 42 1/8″ × 12 3/8″. • Fuel: Electric. • Controls: Remote with thermostat and 7-day schedule; more settings through the Napoleon Home app and voice control with Google Home and Alexa. • Fan: Included Who It’s For You’ve got the wall picked out, but a traditional fireplace there means a gas line, a vent run, and framing that eats into the room. You need a fireplace that fits inside the wall you already have . If you want a wide linear fire as the focal point of a bedroom, den, or office—hung on the wall or set flush into it—the Astound SlimMount 42 is the one. Choose a deeper unit instead and you’re building out the wall to hide it. What Makes It Special The whole unit is four inches deep , so it recesses into a standard framed wall without excessive construction, or mounts on the surface with barely any projection. Edge panels and trim come in the box for either install, and it plugs into an outlet or can be hardwired. Recessing still means opening the wall, so count that as part of the job. The fire earns the spot. The flame effect mimics the movement of a real fire, and the tinted, anti-glare glass means you see the flames, not your lamp reflected back. There are 13 top light and ember color options on the remote and more through the Napoleon Home app, and the included remote runs everything—on/off, thermostat, 7-day schedule, flame, ember bed, and top lights. The heat is real, too—enough for a bedroom or a den. ECO mode runs at half heat and uses less energy; BOOST runs the heater at maximum with the fan turned up for a cold morning. It’s backed by a 3-year registered warranty . Possible Downsides • The heater warms one room, not the house. Figure roughly 150–250 square feet of comfort heat—it supplements the furnace, it doesn’t replace it. • It needs its own dedicated circuit. A dedicated 15 amp grounded circuit is required, so an electrician may be part of the install. • The colored glass ember kits are optional, not included. The fireplace ships with woodland glass; amber, black, blue, clear, red, and topaz embers are add-ons. If you want a fire on the wall without a construction project, the Astound SlimMount is the right decision. The wall you used to walk past becomes the room everyone ends up in. Media options run from the included woodland glass to optional glass ember kits in amber, black, blue, clear, red, and topaz and a black crystal kit, with flame colors in orange, yellow, or both, and an optional wall mount controller with a black or white faceplate.

Corner Wall Mount Smart
A fire built for the corner, where a full fireplace won’t go. Quick Facts • Heating Capacity: Up to 400 sq ft. • Fuel: Electric. • Controls: Remote with two heat settings and an auto thermostat mode. • Fan: Included Who It’s For Some rooms have no wall to spare, only a corner that sits empty. You need a fire shaped for a corner, not a flat wall. The Amantii Corner Wall Mount Smart is for the small room or nook that wants a modern corner fire. Choose it for the look and warmth in the room; it is supplemental heat. What Makes It Special It installs two ways, built in or mounted across a corner , behind a curved black glass surround with a modern, geometric look. The heater runs on low or high, or on auto to hold the temperature you set, and warms up to 400 square feet. The flames run with or without the heat. Possible Downsides • It is supplemental heat. The heater warms the room you are in, not the whole house; the flames also run with the heat off. • It is shaped for a corner only. For a flat wall, look at Amantii’s Wall Mount/Flush Mount linear fires. If you have a corner and want a fire in it, the Amantii Corner Wall Mount Smart is the right decision. The empty corner becomes the coziest seat in the room. Install it built in or mounted across the corner.
A nearly frameless linear fire that hangs on the wall and plugs in. Quick Facts • Heating Capacity: Up to 400 sq ft. • Fuel: Electric. • Controls: Full-feature remote and touch controls that dim when not in use. • Fan: Included Who It’s For You want a modern linear fire, but opening a wall isn’t in the plan. You need one that hangs, plugs in, and still looks clean. The Fire & Ice Evolution Linear 36 is for the room that wants a 36-inch linear fire with a minimal frame. Choose it for the look and warmth in the room; it is supplemental heat. What Makes It Special The black, nearly frameless design keeps the focus on the flames. It hangs on the wall and plugs into a standard outlet, or builds into the wall. High-intensity LEDs in the flames and ember bed keep the fire visible in a bright room, the controls glow when you need them and dim when you don’t, and the heater warms up to 400 square feet. Fire & Ice backs it with a one-year warranty; a log set is optional. Possible Downsides • It is supplemental heat. The heater warms the room you are in, not the whole house; the flames also run with the heat off. • The warranty is one year. Amantii’s Symmetry series carries two or five. If you want a clean linear fire without construction, the Fire & Ice Evolution Linear 36 is the right decision. The wall gets a fire the same day it goes up. Choose the 36-, 42-, 50-, or 60-inch size, and add the optional log set.
