Frequently Asked Questions

  • The Napoleon Ascent X 36 Direct Vent Gas Fireplace generates up to 26,000 BTUs of heat output, making it suitable for a variety of living spaces. It features a built-in blower that helps distribute warmth evenly throughout the room. For larger spaces or to redirect heat to other rooms, an optional Hot Air Distribution Kit or Universal Heat Management System is available.

  • Yes, the Napoleon Ascent X 36 must be installed by a licensed, authorized service technician or contractor, and installation must comply with all local and national building and fire codes. The unit requires a chimney with a 4-inch inner diameter for direct venting, and it supports both top and rear vent configurations. Zero-clearance construction simplifies installation in new builds or renovations.

  • Yes, the Napoleon Ascent X 36 is available in both natural gas and propane models. The electronic ignition system includes a battery backup, ensuring the fireplace continues to operate even during a power outage. The millivolt ignition option also does not require any electricity to light the fireplace.

  • Napoleon gas appliances like the Ascent X 36 carry a Lifetime Limited Warranty covering key components such as the combustion chamber, heat exchanger, stainless steel burner, PHAZER logs, ceramic glass (against thermal breakage), and porcelain-enameled surfaces. Electrical and wearable parts — including blowers, gas valves, ignitors, and remote controls — are covered for the first year, along with labor for warranty repairs. The warranty is non-transferable and requires purchase through an authorized Napoleon dealer.

  • The Ascent X 36 comes standard with a remote control, a built-in blower, and Napoleon's exclusive NIGHT LIGHT™ feature that illuminates the firebox and logs even when the fireplace is off. The optional eFIRE app allows full control of the fireplace and blower — including flame height adjustment — from an iOS or Android device via Bluetooth. Mounting a TV above the fireplace is possible with the optional Heat Management System, which redirects heat away from above the unit to reduce clearance-to-combustibles requirements.
