Napoleon Ascent Deep Series

The key difference is firebox depth — the Ascent Deep features an extra-deep 22-inch firebox, while the standard Ascent is designed with a shallower depth for versatile installations where space is limited. The deeper firebox gives the fire a more luxurious, dimensional appearance, making every inch of the flame visible and more immersive. Both series share the same ease of installation and wide range of customization options.

The Napoleon Ascent Deep Series produces up to 31,000 BTUs of heat output, which is sufficient to warm most average-sized living rooms comfortably. An optional blower accessory can be added to distribute warm air more efficiently throughout the space, further reducing utility costs. Both natural gas and propane models are available to suit your fuel preference.

Yes, but it requires the optional Heat Management System, which reduces clearance to combustible materials during installation for greater interior design flexibility. This system redirects heat away from directly above the fireplace, allowing electronics, artwork, and TVs to be placed closer without risk of heat damage. Always follow Napoleon's installation manual clearance guidelines for safe placement.

The Napoleon Ascent Deep is a direct vent gas fireplace, meaning it does not require a traditional chimney and can be vented horizontally through a wall or vertically through the roof. It supports both rigid and flex venting configurations, giving installers flexibility for a variety of home layouts. The direct vent system draws combustion air from outside, so it does not consume indoor air or create drafts.

The Napoleon Ascent Deep is backed by Napoleon's President's Limited Lifetime Warranty, which covers defects in materials and workmanship — including the combustion chamber, burner, log set, and ceramic glass — for as long as the original purchaser owns the appliance. Electrical components and wearable parts such as gas valves, blowers, and igniters are covered for the first year, including free replacement parts. Labor for warranty repairs is also covered free of charge during the first year through an authorized Napoleon dealer.
