Napoleon Ascent Linear Premium Fireplace

Napoleon Ascent Linear Premium Gas Fireplace Selection and Installation

Find the fire that fits your home

The Napoleon Ascent Linear Premium is for homeowners who want a wide, contemporary fire without giving up a natural-looking interior. Its horizontal format can anchor a media wall, balance a long living room or become the visual center of a redesigned gathering space. Chimneys Plus helps choose the scale and presentation before the surrounding wall is committed.

Serving the Triangle and surrounding Central North Carolina communities.

What makes this family different

The family combines a linear view with included lighting, a blower and remote control. Approved log and glass presentations provide different moods, from the texture of wood to a more minimal flame display. Current sizes are 42, 46, 56 and 76; the exact size and accessory package should be confirmed for the project rather than assuming every option transfers between models.

Selection and installation, considered together

This is a good comparison point when you want more built-in lighting and control features than a simpler linear fireplace. Heat-management options must be planned alongside the wall finish and television, not added as a cosmetic afterthought. We also consider low-fire comfort: a fireplace that looks right should be enjoyable in the room where you spend time. Napoleon classifies this as a decorative appliance, not a rated backup-heating system or a replacement for home heating.

This is a complete built-in gas fireplace with its own firebox, not an insert that requires a separate existing fireplace. Its direct-vent combustion system uses outside air and exhausts outdoors rather than using already conditioned room air for combustion. A suitable vent route, the complete enclosure, finish materials and service access all matter; the appliance’s body dimensions alone do not establish installation fit.

Chimneys Plus handles or coordinates gas piping, required electrical work and permitting. We check the fuel supply and the selected model’s requirements before finalizing the installation. The current BLX42/46/56/76 installation manual requires hardwiring. Lighting and the circulating blower need household power; battery backup does not remove this installation requirement.

Frequently asked questions

Why choose the Napoleon Ascent Linear Premium over a simpler linear fireplace?

It includes conveniences such as a blower, remote and accent lighting. Compare it when the everyday experience and interior finish choices are as important to you as the long horizontal shape.

How much heat will a Napoleon Ascent Linear Premium add to my room?

Napoleon identifies this as a decorative appliance, not a room heater. The published input range describes fuel use, not heat delivered or a guaranteed room size. We consider the chosen model, room layout, insulation and how often you want the fire on. The larger size is not automatically the more comfortable choice.

Can the Napoleon Ascent Linear Premium operate during a power outage?

Yes! The documented BLX42/46/56/76 battery-backup arrangement can retain burner on/off and flame control when gas and the specified batteries are available. Lights, blower and powered heat-distribution accessories do not run from those control batteries. This is outage flame operation, not a guaranteed backup-heating system; any power-vent configuration requires separate review.

Does the Napoleon Ascent Linear Premium require an electrical connection?

The current BLX42/46/56/76 installation manual requires hardwiring. Lighting and the circulating blower need household power; battery backup does not remove this installation requirement. We coordinate the electrical work, so you do not need to arrange that part of the project separately.

Can a Napoleon Ascent Linear Premium be built into a television wall?

Yes, where the completed design meets the fireplace, approved heat-management kit and television requirements. We plan the enclosure outlets, finishes and clearances together; a product photo is not an installation specification.

Can the Napoleon Ascent Linear Premium use an existing gas line?

Possibly. Chimneys Plus checks fuel type, pipe capacity, pressure, shutoff access and the demand from other appliances. An existing connection does not automatically mean that the line is adequate for the new fireplace.

Does installing or replacing a Napoleon Ascent Linear Premium require permits?

Yes, fireplace switch-outs require permitting even when a gas line already exists. Chimneys Plus confirms the applicable requirements and handles permits for the installation.

How should I maintain a Napoleon Ascent Linear Premium?

Follow the model’s care instructions and arrange qualified inspection and service at least annually. Burner and pilot condition, approved media placement, glass, controls and venting all deserve attention. Keep required barriers installed and keep enclosure air openings unobstructed.
