Napoleon Astound 74" Built-In Linear Electric Fireplace

Seventy-four inches of flame to anchor an open plan, with no vent run.

A built-in linear electric fireplace with orange, yellow or combined flame and a spark effect through the ember bed. No gas line, no venting, no flue.

The open plan finally has a center.

Kitchen, dining and living all look toward the same wall now. At 74 inches the Astound spans a true feature wall or runs beneath a large television, with no flue, vent run or gas line behind it.

Flip down the front glass to change the look: Beach Fire logs, the Woodland kit, or your own glass and stone.

What it does for your home

Comfort, on demand. Up to 10,000 BTU (3,000 W) of supplemental heat. The flame runs independently of the heater, so you can keep the fire in summer.

A room that feels finished. A frameless finishing flange and an adjustable trim are both included, so the long line of flame reads as part of the architecture.

A real home upgrade. It builds into the wall like a gas firebox and needs nothing behind it: no flue, no vent run, no gas line. Hardwired at 120V or 240V.

Easy from the sofa. Premium remote included, plus Napoleon Home app control and voice control through Google Home and Alexa. Nothing to light.

Overview

Six feet of fire for the wall that has to carry the room

At 74 inches the Astound spans a true feature wall — wide enough to anchor a great room, run beneath a large television, or give an open-plan space a single focal point — and it does it without a flue, a vent run, or a gas line. If you want the presence of a wide linear gas fireplace without the cost and constraints of venting one, this is the size that delivers it.

The front glass flips down, so the media bed changes whenever you want it to: Beach Fire logs, the Woodland kit, or your own glass and stone. Best for great rooms, long media walls, open-concept living spaces, and remodels where venting was never on the table.

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.

The look of a custom build. A frameless, recessed flame gives your wall the finish of a high-end renovation.

A focal point your space has been missing. Your furniture has an anchor, and the room finally feels complete.

Questions Buyers Ask Before Ordering

Will it fit my wall?

It installs built-in and recessed. Framing and rough-opening dimensions 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 Astound Built-in hardwires at 120V or 240V, so plan for a licensed electrician and a dedicated circuit before the wall is closed up.

Does the 74-inch give more heat than the smaller sizes?

No. Every Astound Built-in size is rated up to 10,000 BTU (3,000 W). At this width you are buying flame length and presence, and the flame can run without the heater.

Can I change the look later?

Yes. The front glass flips down for tool-free media changes. The Beach Fire log set and Woodland media kit are both included, and you can add decorative glass, stone or seasonal décor.

Does it need venting or a gas line?

Neither. It goes on an interior wall, in a condo, or in a finished basement where a direct-vent run is not possible. It does need an electrical connection.

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 frame.

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.
