Napoleon Ascent Linear Premium 42 Direct Vent Gas Fireplace


The Napoleon Ascent Linear Premium 42 is for people who want a long, clean line of fire with a log set sitting in it. The glass opens up a 37.5 by 16.75 inch view, wide and low, so the fire reads like a picture across the wall instead of a box in the corner.

A lot comes in the box. The heat circulating blower, the eFIRE controller and remote, and the safety barrier are all included. You choose the log set, driftwood, birch, or split oak; it's sold separately and required to finish the fireplace. It's built in Ontario, Canada, runs on natural gas with electronic ignition, and vents direct vent through the top or rear.

What Makes the Ascent Linear Premium 42 Different

  • Blower and remote already included. The heat circulating blower and the eFIRE controller and remote come standard, so you're not adding them later to get fan-assisted heat and easy control.
  • Your pick of log sets. Driftwood, birch, or split oak logs give the linear fire a traditional look. One of them is required to complete the unit, and we'll help you choose.
  • Night Light system. Napoleon's Night Light system is built in, giving the firebox a soft glow of its own.
  • Panel options. Optional Mirro-Flame reflective porcelain panels or a brick panel let you change the look of the firebox walls behind the logs.

This listing is the Napoleon BLX42NTE, the Ascent Linear Premium 42 direct vent gas fireplace for natural gas with electronic ignition. BLX42NTE is the current code for the earlier BLP42NTE. A log set is required and sold separately.
