A fire that fits the way you live
Astound FlexMount gives you more than one route to a finished fireplace wall. Keep it on the wall for a three-sided view, recess it partway to reduce its projection, or build it into a one-, two- or three-sided enclosure. Choose a size here, then plan the viewing arrangement, framed opening and power supply with your installer.
Orange and yellow flames move above the supplied Beach Fire logs and Woodland media. The spark effect adds another layer of movement. Settle on a familiar glow or change the ember-bed and top lighting to suit the evening.
The flame can run with the heater off. When you want extra warmth, use the heater controls to suit the room rather than making heat part of every evening.
See the fire before you decide
Choose orange flames, yellow flames or both together, then adjust brightness and flame speed. The ember bed and top lights each offer thirteen colors with cycling options, giving you control over the background glow as well as the fire itself.
Start with the supplied logs and Woodland media before considering a different decorative treatment. They give the fireplace its intended starting appearance without an immediate media purchase.
Comfort within reach
The premium remote is included, with everyday touch controls on the appliance. Pair with the Napoleon Home App over Wi-Fi for phone control, or use the supported Google Home and Alexa integrations. A separate wall-mounted controller is optional.
ECO mode runs the heater at half output. Boost selects enhanced heater operation with a higher blower speed. The remote also supports a weekly on/off schedule. These functions let you choose how the heater works alongside the separate flame and lighting controls.
Plan the wall and the wiring together
Wall mounting keeps the fireplace on the room side of the wall with three visible sides. Partial recessing reduces its projection while retaining those side views. Full recessing supports a single-sided finish, an open corner with two visible sides, or a three-sided enclosure. Match the finishing panels and framing method to that choice.
| Outside width | 62 in |
|---|---|
| Inside width | 61 11/16 in |
| Height | 23 in |
| Depth | 7 1/8 in |
| Rough-opening width | 62 1/2 in |
| Rough-opening height | 23 7/16 in |
| Full-recess framing depth | 7 1/2 in |
| Partial-recess framing depth | 3 1/2 in |
The fireplace is not load-bearing. Support the wall finish independently and keep air openings clear. For full recessing, each model needs a rough opening 1/2 inch wider than its outside body, 23 7/16 inches high and 7 1/2 inches deep. Partial recessing uses the same opening width and height with a 3 1/2-inch framing depth. Follow the manual for the chosen viewing arrangement, mantel and finishing details.
The included cord supports a 120-volt wall-mounted installation. Recessed installations must be hardwired by a qualified electrician. The appliance supports 120-volt or 240-volt hardwiring; maximum input is 1,500 watts at 120 volts or 3,000 watts at 240 volts.

Turn the fireplace off, disconnect its power supply and let it cool before cleaning. Clear dust from the heater and vent areas with a vacuum or duster. Apply a suitable glass cleaner to a soft cloth rather than spraying the fireplace; avoid abrasive products. The manual gives separate care instructions for glass, metal and plastic.
Yes. Wall mounting, partial recessing and full recessing are supported. Wall mounting uses the supplied bracket and a suitable grounded 120-volt connection. Both partial and full recessing require hardwiring by a qualified electrician; a plug-in cord must not be concealed inside the framed wall.
Yes. Wall-mounted and partially recessed installations retain the front and side views. For a fully recessed installation, the supplied finishing arrangement supports a single-sided, two-sided or three-sided presentation. Plan the view with your installer before framing and use the matching installation instructions.
Maximum electrical input increases from 1,500 watts at 120 volts to 3,000 watts at 240 volts. The 240-volt option requires hardwiring. A qualified electrician should plan the circuit and connection for the installation.
Yes. The flame effect can operate while the heater is off. Fan-only and heater settings are also available, and the appliance has a heater lockout function.
Beach Fire logs and the Woodland media kit are included. The 50-inch model has 5 logs, the 62-inch has 6 and the 74-inch has 7, with supplied glass, rocks and charcoal forming the media bed. Follow the selected size’s placement diagram before arranging the media. Optional decorative treatments are separate purchases.
A premium remote is included, and the fireplace also has touch controls. The wall-mounted controller is optional. Napoleon Home App control and supported voice integrations provide additional control choices.
Yes. Pair the fireplace with the Napoleon Home App over Wi-Fi. App setup requires an account and the pairing steps in the manual. The included remote remains a separate way to operate the fireplace.
ECO runs the heater at half output. Boost selects enhanced heater operation with a high blower setting. These are operating modes, rather than a change to the installation or electrical supply.
No. Astound FlexMount is an indoor electric fireplace. Choose a location protected from moisture and follow the exact installation clearances; an outdoor setting is not an approved application.
No. NEFL50AB, NEFL62AB and NEFL74AB have outside body widths of 50, 62 and 74 inches. Their rough-opening widths are 50 1/2, 62 1/2 and 74 1/2 inches respectively. The opening is 23 7/16 inches high; depth depends on partial versus full recessing. Use the exact-model drawing before building.

EXTERNAL CUSTOMER FEEDBACK
OUR PRODUCT ASSESSMENT
A three-sided fireplace earns its keep when people see it from more than one direction. We’d choose the Astound for a long room where the sofa faces the fire and the dining table sees it from the side. The included logs and woodland pieces give the flame something to move behind, and you can change the lighting without turning up the heat. Decide which glass sides will stay visible before choosing the width or drawing the wall.
Owners give a good sense of how this fireplace lives in a room. One built a mantel around it and left all three sides exposed, enjoying the fire even when the room was already warm. Another chose the side glass for a narrow room, found the blower quiet in their installation and used the app and voice controls in place of the remote.
The glass ends make the flame visible on the approach to the room as well as from the sofa. The Beach Fire logs and Woodland media are included, so you can lay out the bed before deciding whether you want extra decoration.
Mock up the finished wall depth as well as the fireplace width. A return wall or a tall cabinet right beside the glass can hide the very view you’re buying. Have the installer show you how the front glass comes off after finishing.
The extra spend makes the most sense for a corner, a projecting wall or an open-plan room. If every seat faces straight ahead, compare the simpler Entice before paying for side glass you’ll rarely see.
