Napoleon Astound electric fireplaces combine a modern linear design with realistic flame movement, flexible installation options and smart controls. The series is available in two distinct styles—Astound Built-In and Astound FlexMount—so the fireplace can be matched to the way the room and feature wall are being designed. Both use Napoleon's spark-effect flame technology, customizable lighting and natural-looking media to create more depth than a basic linear electric fireplace.

Choose Between Astound Built-In and FlexMount
The biggest decision when choosing a Napoleon Astound Series electric fireplace is the installation. Astound Built-In is designed for a permanent, fully recessed single-sided installation with a deeper firebox and large viewing area. Astound FlexMount uses a shallower, more adaptable design that can be wall mounted, partially recessed or fully recessed and configured for one-sided, two-sided or three-sided viewing. Both share many of the same flame, lighting, media and smart-control features, but they are designed for different types of projects.
Napoleon Astound Built-In Electric Fireplaces
Astound Built-In is the choice for a clean, integrated fireplace that becomes part of the finished wall. Available in 50-inch, 62-inch, 74-inch and 96-inch sizes, these models are designed specifically for fully recessed installation. The extra-large viewing area and tinted front glass help keep the flame display prominent while reducing reflections, and the included finishing options allow the fireplace to be completed with either a streamlined frameless appearance or an adjustable trim when additional coverage around the opening is preferred.
One of the most useful features of the Built-In design is its flip-down front glass, which provides convenient access to the logs and media. A Beach Fire log set and Woodland media kit are included, while optional birch logs, mineral rocks, glass beads and black crystals provide additional ways to change the appearance. This makes Astound Built-In well suited to custom feature walls where both the fireplace itself and the media presentation are important parts of the finished design.
Napoleon Astound FlexMount Electric Fireplaces
Astound FlexMount is designed for projects where installation versatility is the priority. Available in 50-inch, 62-inch and 74-inch sizes, FlexMount models can be wall mounted, partially recessed or fully recessed. They can also be configured as a traditional single-sided fireplace or with one or both side panels open for two-sided and three-sided viewing.
That flexibility makes FlexMount particularly useful for media walls, corner installations and feature walls where exposed side glass can become part of the design. It is also a practical option when the available wall depth makes a deeper built-in firebox less desirable. Customers specifically looking for wall-mounted and multi-view options can compare Astound with the other models in our Napoleon linear electric fireplace collection.
Realistic Flames and Customizable Lighting
Both Astound styles use spark-effect flame technology designed to add movement and depth to the fire. Orange and yellow flames can be used independently or together, allowing the display to range from a warmer traditional appearance to a brighter layered flame effect. Tinted glass further enhances the flame presentation by helping reduce reflections in brighter rooms.
The flame is only part of the visual experience. Astound fireplaces also include an illuminated ember bed and overhead lighting with 13 standard color options. Additional customization is available through the Napoleon Home app, making it possible to coordinate flame, ember-bed and top-light settings with the room or desired mood. The included Beach Fire logs and Woodland media create a more natural hearth appearance, while optional media kits provide additional contemporary and traditional styling choices.
Smart Controls and Supplemental Heat
The Napoleon Astound Series can be controlled with the included remote, built-in controls or the Wi-Fi-enabled Napoleon Home app. Compatible Google Home and Alexa devices also provide voice-control options for select functions. The app expands the available customization and provides features such as favorite settings and scheduling, making Astound especially useful for customers who want a fireplace that can be integrated into a connected home.
Astound fireplaces also provide supplemental room heat, with ECO and BOOST modes for different comfort needs. Current models can operate on 120-volt or 240-volt power depending on the fireplace and installation, with higher heat output available when properly configured for 240-volt operation. Electrical and hardwiring requirements vary between Built-In, wall-mounted and recessed FlexMount applications, so the specifications and installation manual for the selected model should always be reviewed before planning the electrical connection.
Astound Built-In vs. FlexMount: Which Is Better for the Project?
Choose Astound Built-In when the goal is a permanent, fully recessed linear fireplace with a deeper firebox, large single-sided viewing area and integrated finished appearance. It is also the only Astound style currently offered in the extra-wide 96-inch size. Choose Astound FlexMount when wall mounting, a shallower installation, partial recessing or two-sided and three-sided viewing is important.
For customers who already know they want the Astound flame technology but are unsure which version to buy, the installation style should usually be decided first. Once that is established, selecting among the available 50-inch, 62-inch, 74-inch and 96-inch models becomes much easier. Always use the actual fireplace and framing dimensions rather than the nominal model size when planning a recessed installation.
Benefits of Napoleon Astound Electric Fireplaces
Because Astound is electric, there is no chimney, gas line or combustion venting required. This creates considerably more flexibility when designing a fireplace into a living room, bedroom, entertainment space, office or custom media wall. The flame and lighting effects can also be enjoyed independently of the heater, allowing the fireplace to remain part of the room's ambiance throughout the year.

Napoleon Astound Series Electric Fireplaces FAQs
What is the difference between Napoleon Astound Built-In and Astound FlexMount?
The main difference is how the fireplace can be installed. Astound Built-In is designed for a permanent, fully recessed single-sided installation and provides a deeper firebox with an extra-large viewing area. Astound FlexMount can be wall mounted, partially recessed or fully recessed and can be configured for one-sided, two-sided or three-sided viewing. Both offer Astound spark-effect flames, customizable lighting, smart controls and supplemental heat, so the best choice usually comes down to the desired installation and finished appearance.
What sizes are available in the Napoleon Astound Series?
Astound Built-In is available in 50-inch, 62-inch, 74-inch and 96-inch sizes, while Astound FlexMount is available in 50-inch, 62-inch and 74-inch sizes. The nominal size is useful for comparing models, but it should not be used as the final framing measurement. Always compare the actual overall dimensions and required framing dimensions in the specifications or installation manual before ordering a fireplace for a recessed application.
Can a Napoleon Astound electric fireplace be wall mounted or installed as a three-sided fireplace?
Yes, but only the Astound FlexMount provides those installation options. FlexMount models can be wall mounted, partially recessed or fully recessed and configured for single-sided, two-sided corner or three-sided viewing. Astound Built-In models are designed specifically for fully recessed, single-sided installations. Customers who need exposed side glass or greater flexibility in wall depth should generally consider FlexMount first.
How much heat does a Napoleon Astound electric fireplace provide, and does it require 240 volts?
Napoleon Astound fireplaces can provide up to 10,000 BTUs of supplemental heat when properly configured for 240-volt operation, while current models can also operate at 120 volts with lower heat output. The exact wiring method depends on the model and whether the fireplace is wall mounted or recessed. Built-In models require hardwiring, while FlexMount electrical requirements change with the installation method. Always review the selected model's specifications and installation manual, and use a qualified electrician when hardwiring is required.
