About this model
The Astound Built-in is Napoleon's recessed electric fireplace in four widths from 50 to 96 inches, with an extra-large viewing area and a spark flame effect.
The Flip-Down Glass
The Astound Built-in's front glass swings down on a hinge, so changing the logs, glass beads or mineral rock doesn't mean taking the fireplace apart.

Sizing to Your Wall
The fireplace should span roughly half to two-thirds of the wall section it anchors (full size guide →). The 96" needs a wall that can carry it — check the width before ordering.
Built-in or FlexMount?
This is the recessed-only version. If you want the option of hanging it on the wall, the Astound FlexMount mounts on the wall, partly recessed or fully recessed.

Before you order
Questions people ask about this kind of product
Will this fit my wall?
The dimensions on the page are the appliance body; framing and rough-opening sizes are different numbers and come from the manufacturer's installation manual linked on the page. Call or text (814) 440-4817 with your wall width and height and we'll confirm the right size before you order.
Do I need a professional to install it?
Gas appliances: yes, a licensed gas installer, and most jurisdictions require a permit and inspection. Electric fireplaces are simpler but hardwired models need an electrician. We don't install — we supply the manufacturer's installation manual and clearance specs so your installer and inspector have what they need.
What's included, and what do I need to add?
Each product page lists what ships in the box. Log sets, glass media, decorative fronts, mantels and venting kits are usually separate items — tell us what look you want and we'll put the complete build on one quote so it ships together where possible.
Is freight included, and how long until it arrives?
Freight is included to the 48 contiguous states, with liftgate delivery and no surcharges at checkout. Your order typically ships in 1-3 business days, and most deliveries arrive in 1-2 weeks from your order. We provide tracking once it ships, and the carrier calls to schedule delivery. Alaska, Hawaii, U.S. territories and international are quote-only — call before ordering.
What happens if it arrives damaged?
Look the crate over before you sign, write any damage on the delivery receipt (even "box damaged"), take a couple of photos, and contact us right away. For damage you find after unboxing, contact us as soon as you see it. We'll take it up with the distributor and manufacturer.
Can I return it?
Yes, within 30 days of delivery, if it's unused, unassembled and in the original packaging. Approved returns carry a 20% restocking fee and the customer covers return freight unless the return is due to our error or a defect — on a large freight item that is real money, which is exactly why we check the size and setup with you before you order. Special-order and custom-finish items can't be returned. Full terms: Refund policy.
