Napoleon Astound 50 FlexMount: a wall hanging fireplace with glass sides
The Napoleon Astound 50 FlexMount is a wall hanging electric fireplace that can also sit partly or fully inside the wall. It is 50 inches wide. You can leave the glass sides showing for a view from around the room. Orange and yellow flames have spark effects. Colored lights brighten the area beneath the logs.
It needs no gas line and no chimney. It provides up to 10,000 BTU of heat. Run the flames with or without heat. ECO mode runs the heater at half power. BOOST mode turns the heater and fan all the way up. It comes with a remote. You can also run it from your phone with the Napoleon Home app or by voice through Google Home or Alexa. Beach Fire logs and a Woodland Kit come in the box. On the page you can add birch logs, glass beads, or a wall mounted controller, and more. Napoleon backs it with a 3 year warranty.

FAQ
What does FlexMount mean on the Astound 50 FlexMount?
Two installs in one unit: hang the NEFL50AB on the wall like artwork, or recess it into a shallow cavity — minimum framing just 50.75 x 26.25 x 7.50 in — whichever the room calls for.
Does the Astound 50 FlexMount actually warm the room?
Yes — up to 10,000 BTU (3 kW) of fan-forced heat per its spec sheet, alongside a 50 x 18 in flame display that also runs heat-free for ambiance.
How shallow is the Astound 50 FlexMount?
Just 7 in deep — nearly half the depth of the built-in Astound — which is what makes surface wall-mounting a clean, low-profile option.
What does it cost to run the Astound 50 FlexMount?
About 45–50 cents per hour at full heat at typical U.S. electricity rates, and only pennies in flame-only mode.
Does the Astound 50 FlexMount need venting?
No venting, gas, or chimney — fully electric. Condos, offices, and bedrooms are all candidates; just have the 3 kW circuit confirmed by an electrician.
Can the Astound 50 FlexMount produce carbon monoxide?
No — there is no combustion. It emits light and warm air only, making placement an interior-design decision rather than a safety one.
What is the Astound 50 FlexMount’s warranty?
A 3-year limited warranty from Napoleon, included fully through our authorized-dealer status.
