Napoleon Ascent Deep 42 Direct Vent Gas Fireplace

  • Deeper Firebox, Richer Flames: The extended firebox depth creates a fuller, more dimensional flame that closely mimics a traditional wood-burning fireplace — giving your room an authentic, inviting focal point.
  • Realistic Logs and Embers: Hand-painted ceramic logs and a glowing ember bed deliver a lifelike fire experience that adds warmth and character to any living space without the mess of real wood.
  • Flexible Ignition and Controls: Choose between millivolt or electronic ignition and operate your fireplace via wall switch, remote control, or app — putting comfort and convenience at your fingertips.
  • Heat Management System: The optional heat management system redirects warmth away from the wall above, making it safe to mount a TV or hang artwork directly over the fireplace without worry.
  • Fully Customizable Aesthetic: Select from a range of decorative fronts, trim kits, and interior brick panels to tailor the fireplace's look to your home's style — from classic to contemporary.
  • Lifetime Warranty Backed Confidence: Napoleon's President's Limited Lifetime Warranty means you're investing in a fireplace built to last, with manufacturer support that protects your purchase for the long haul.

Frequently Asked Questions

  • The Napoleon Ascent Deep 42 (D42NTRE) produces a maximum of 26,000 BTUs, which is capable of heating up to approximately 700 square feet. This output is notably higher than the standard Ascent 42 (B42NTRE), which tops out at 22,000 BTUs, making the Deep model a better choice for larger living spaces.

  • The Ascent Deep 42 requires minimum framing dimensions of 42 inches wide, approximately 40.88 inches high, and 23 inches deep. The actual unit itself measures 40.25 inches high by 37.44 inches wide by 23.75 inches deep, and the extra-deep 22-inch firebox depth is what distinguishes this model from the standard Ascent 42 series.

  • The Ascent Deep 42 is a direct vent fireplace that accepts both top and rear venting via a 5-inch/8-inch vent system. It supports both rigid and flexible venting, including Napoleon's Freedom Flex Venting system, which can save significant time and labor costs compared to traditional rigid venting.

  • Yes, the Ascent Deep 42 includes a battery backup control system, so the fireplace can still be operated even when the power goes out. The electronic ignition (IPI) model relies on this battery backup to ensure continuous comfort during outages, making it a reliable heating source in emergency situations.

  • The Napoleon Ascent Deep 42 is covered by Napoleon's President's Limited Lifetime Warranty. During the first 10 years, Napoleon will replace or repair any defective covered parts free of charge; from 10 years onward, replacement parts are provided at 50% of the current retail price for the lifetime of the product.
