The Ascent™ 42 is Napoleon's best-selling direct vent gas fireplace — a clean-burning, sealed-combustion firebox that delivers real radiant heat with 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
- 25,000 BTU/h with flame and heat adjustment — dial the output to the room
- PHAZER™ log set and ember bed included — a deep, realistic fire straight 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 and Fuel Type above are required — they determine the factory unit you receive. Millivolt ignition uses a standing pilot and operates without electricity; Electronic ignition uses an intermittent pilot for higher efficiency. Interior Panels are optional — the firebox ships with a painted black interior. 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. Decorative fronts, surrounds, finishing trim, media kits, the blower kit and remote upgrades are optional and listed under Related Products below.
