The Ascent™ 46 is part of Napoleon's best-selling direct vent gas line — a clean-burning, sealed-combustion firebox that delivers real radiant heat behind the tall, full flame of the PHAZER™ log set. It vents horizontally through a wall or vertically through the roof, so it drops into almost any room in a NYC apartment, Long Island home or New Jersey build.
Key Features
- 30,000 BTU/h with flame and heat adjustment — dial the output to the room
- PHAZER™ log set and ember bed included — a deep, realistic fire out of the box
- Battery back-up control keeps the fireplace running through a power outage
- Tempered heat-resistant glass with standard safety barrier — safe around children and pets
- Top or rear 4"/7" direct venting for flexible placement
- President's Limited Lifetime Warranty on the firebox and burner
Choosing Your Configuration
Ignition above is required — it determines the factory unit you receive. Millivolt uses a standing pilot and runs without electricity; Electronic uses an intermittent pilot for higher efficiency. Interior Panels and Decorative Front are optional — the firebox ships with a painted black interior and the standard safety barrier. MIRRO-FLAME™ reflective porcelain brightens and deepens the firebox; Westminster™ brick adds a traditional masonry look.
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. Finishing trim, surrounds, media kits, the blower kit and remote upgrades are optional.
