Napoleon Astound FlexMount 50" Linear Electric Fireplace
Description
Want a fully flush, built-in look instead? See the Astound Built-in 50".
Hang it, partly recess it or build it in. One, two or three sides.
A 50-inch linear electric fireplace with orange and yellow flame, a spark effect and 13 ember bed and top light colors. No gas line, no venting, no flue.
On the wall, in the wall, or between two rooms.
Hang it with no framing at all, recess it partway, or build it in fully. Set it up as a 1-, 2- or 3-sided fireplace for a room divider or peninsula, and the flame shows from more than one angle.
The Beach Fire logs and the Woodland media kit both come in the box, so the look is yours to choose.
What it does for your home
Comfort, on demand. Up to 10,000 BTU (3,000 W) at 240V, or 5,000 BTU (1,500 W) at 120V. ECO mode runs at half heat; BOOST runs at max heat with a faster blower.
A room that feels finished. Finishing edge panels and trim are included, so it looks complete on the wall or in it.
A real home upgrade. Wall-mount, partially recessed or fully recessed, with nothing to vent. Hardwired at 120V or 240V.
Easy from the sofa. The included remote handles on/off, thermostat, a 7-day schedule, flame, ember bed and top lights, with Napoleon Home app and Google Home or Alexa voice control.
Overview
One fireplace, three ways to install it — no venting required
The Astound FlexMount 50" is the most adaptable fireplace in the Astound family. Hang it on the wall with no framing at all, recess it partway, or build it in fully — and configure it as a 1-, 2-, or 3-sided fireplace so the flame shows from more than one angle. There's no flue, no vent run, and no gas line, so it goes where a vented fireplace can't.
Orange and yellow flames with a spark effect, 13 ember bed and top light colors, and both the Beach Fire logs and Woodland media kit in the box. Best for renters and condo owners who can't open walls, room dividers and peninsulas, and anyone who wants to decide on the install style later.
Why It Changes the Room
Every evening, not just holidays. Turn on the flame for a quiet morning or a movie night, with or without heat, all year round.
A finished look, however you install it. On the wall or in it, the clean linear flame gives your space the feel of a high-end renovation.
A focal point your space has been missing. Your furniture has an anchor, and the room finally feels complete.
Width: 50 in · Finish: Black · Heat: up to 10,000 BTU (3,000 W) at 240V · Model: NEFL50AB

Questions Buyers Ask Before Ordering
Will it fit my wall?
It can hang on the wall, recess partway or build in fully. Exact dimensions and clearances are in the Napoleon installation manual; send us your measurements and we will confirm the fit, and send the manual, before you order.
Do I need an electrician?
Yes. The FlexMount is hardwired only, at 120V or 240V. Plan for a licensed electrician, and choose the voltage before wiring, since it sets the heat output.
How much heat does it give?
Up to 10,000 BTU (3,000 W) at 240V, or 5,000 BTU (1,500 W) at 120V. It is supplemental heat, and the flame runs without the heater.
Can it show flame on more than one side?
Yes. It configures as a 1-, 2- or 3-sided fireplace, which suits room dividers and peninsulas.
FlexMount or Built-in: which should I choose?
Choose the FlexMount if you want to hang it on the wall without framing, show the flame on two or three sides, or keep your installation options open. Choose the Astound Built-in if you are framing a wall anyway and want a fully flush, recessed look.
Do I need to buy the media separately?
No. Both the Beach Fire log set and the Woodland media kit ship in the box, along with the finishing edge panels and trim.
Can I mount a TV above it?
Electric fireplaces are generally friendlier to a TV above than gas, since there is no flue and far less heat travelling up the wall. Follow the clearances in the Napoleon installation manual for this model; email us and we will send the current version before you install.
What if it arrives damaged?
Note any box damage on the delivery receipt and tell us, ideally within 48 hours. Every shipment is insured; we handle the claim and the replacement.
What if it is not right for my room?
You have 30 days to return it under our return policy.
Install it your way this season.
The Astound FlexMount 50" ships free, insured, and backed by the full Napoleon warranty. Choose your media and add it to your cart, or send us your measurements and a specialist will confirm the fit.

The Lumiflares Difference
Why Lumiflares
A fireplace is more than a purchase.
It should be an experience.
We're a specialist boutique — not a big-box retailer. Every brand we carry, every product on our site, and every customer we serve gets our full, personal attention. Here's what that means for you.
Personally curated by our founder
We carry Kingsman, Napoleon, Dimplex, SimpliFire and EcoSmart Fire — respected names in fireplaces and fire features — hand-selected by our founder for quality, performance, and safety. When you order, you'll receive a personal thank-you from them directly — because to us, you're not an order number. You're someone trusting us with your home.
100% secure shopping
Our site uses SSL encryption on every transaction. We never store your credit card information — shop with complete confidence.
Authorized dealer — full manufacturer warranty
We're authorized for every brand we sell, so your fireplace comes with the full manufacturer's warranty. Have it installed per the manufacturer's instructions to keep that coverage.
Fully insured shipments
Every order is fully insured against loss or damage in transit. If something goes wrong on the way to you, we handle it — at no cost to you.
30-day returns
Not the perfect fit? Our 30-day return policy is straightforward and fair. We'll help you find the right solution — no pressure, no runaround.
Real support, real people
From the moment you order to the day your fireplace is installed, our team is here for you. Call, email, or reply to any of our messages — we always respond.
Why buying from an authorized dealer matters
Fireplaces are sold online by many sellers who are not authorized by the manufacturer. On a purchase this size, that difference matters. Here's what buying from an authorized dealer protects.
- Your warranty. Some manufacturers only honor their warranty when the unit was bought from an authorized dealer — Napoleon's warranty, for example, requires it. Others, like Kingsman and Dimplex, require warranty repairs to go through authorized dealers or service providers. Buying from us keeps you inside those rules from day one.
- A genuine, factory-new unit. Every fireplace we sell ships through the manufacturer's official distribution channel — not gray-market, used, or reboxed stock.
- Someone who stands behind the sale. If something arrives damaged or isn't right, we work with the manufacturer and distributor on your behalf, so you're never left to sort it out alone.
- The right unit for your home. Fuel type, venting and clearances all have to match your space. We check your project against the manufacturer's manuals before you order, so you buy the right model the first time.
We're an authorized dealer for Kingsman, Napoleon, Dimplex, SimpliFire and EcoSmart Fire. Want proof for the brand you're considering? Just ask and we'll send it.
Free shipping on every order — no minimum required
We ship free to the contiguous United States on all orders. No hidden fees or surprise shipping charges at checkout.
Still have questions? We'd love to hear from you.
Call us at 877-879-9191 or email support@lumiflares.com — our team is here to help you find exactly what you're looking for.
