Napoleon Ascent™ Linear 46 Direct Vent Gas Fireplace
The Ascent™ Linear 46 is a wide, single-sided linear gas fireplace built for modern rooms — a long ribbon of flame behind edge-to-edge glass, sealed direct-vent combustion, and electronic ignition. It installs into a framed wall in a NYC apartment, Long Island home or New Jersey build without a chimney.
Key Features
- Up to 24,000 BTU/h with flame and heat adjustment
- Electronic ignition with battery back-up
- Edge-to-edge ceramic glass with standard safety barrier
- top vent 4″ / 7″ direct venting — no chimney required
- President’s Limited Lifetime Warranty on the firebox and burner
Choosing Your Configuration
Log Kit above is optional — choose a log set or beach-fire kit to dress the burner. Interior Panels are optional — the firebox ships with a painted black interior. MIRRO-FLAME™ reflective porcelain brightens and deepens the firebox; Ledgestone adds a natural stone texture.
A direct vent kit is required to complete this installation and is sold separately — the correct kit depends on whether you terminate through a wall or the roof. Blower kits, heat-management ducting and remote upgrades are optional.
