Napoleon Ascent 36-inch Electronic Ignition Direct Vent Fireplace

The Napoleon Ascent 36-inch Electronic Ignition Direct Vent Gas Fireplace, available as natural gas and propane, combines a traditional fireplace appearance with electronic ignition and flexible built-in installation. Rated at up to 18,000 BTU/hr, the Ascent 36-1 features a pan-style burner, adjustable flame and heat output, a realistic PHAZER log presentation, and a generously sized viewing area for a classic wood-fire look without the need for a traditional chimney.

Both models use an electronic ignition system with Napoleon's Pilot-on-Demand operation. The system provides Intermittent Pilot Ignition (IPI) along with a Continuous Pilot Ignition (CPI) mode featuring an integrated seven-day timer. In IPI mode, the pilot automatically lights before the main burner when the fireplace is turned on and shuts down with the burner when the fireplace is turned off. CPI mode can keep the pilot operating between burner cycles for improved cold-weather startup, while the seven-day timer automatically shuts the pilot off after approximately seven days without fireplace use to avoid unnecessary fuel consumption.

The Ascent 36-1 is equipped with a pan-style burner with flame and heat adjustment, allowing the flame presentation to be tailored to the desired setting. A PHAZER log set is included, along with tempered heat-resistant glass and a standard safety barrier designed to reduce the risk of accidental contact with the hot viewing glass.

The direct vent system uses a dedicated 4-inch exhaust and 7-inch air intake configuration to bring combustion air through the vent system while routing combustion gases outdoors. The fireplace can be configured for top or rear venting, providing flexibility when planning the fireplace location and vent path. 

The electronic ignition models require a properly installed electrical supply. The manual's rating-plate information specifies 115V, 60Hz, less than 12 amps, while the installation checklist references a compliant 110 VAC supply connection. The fireplace must be properly connected and grounded according to applicable electrical codes. The installation manual specifically warns not to wire 110 volts directly to the gas valve or wall switch. Always verify the electrical rating on the actual appliance rating plate before installation.

Alternative firebox media can also be used in place of the standard log presentation. When optional media is installed in the B36, the RR36 support bracket is required.
