Product Overview

The Arlington cast iron gas stove, with its slender, space saving design and 45° venting, is perfect for smaller room applications. Despite being small in size, it holds a large PHAZERAMIC™ burner system and features a brightly glowing ember bed for all the look and feel of a larger stove. Mirro-Flame™ Porcelain Reflective Radiant Panels and Napoleon's exclusive Night Light™ setting are included with the Arlington™ for a complete, top of the line experience.

Napoleon's Direct Vent Gas Fireplaces do not require a chimney and can be vented directly through a wall or roof. The direct vent draws its combustion air from outside while venting to the same outside atmosphere - thereby not consuming warm house air, nor competing with other appliances and furnaces for combustion air. Direct venting also eliminates drafts and heat loss associated with other fireplaces.


  • 20,000 BTUs of heating power keeps your home warm even during the coldest nights
  • Realistic PHAZER® logs create a natural burning wood look
  • Mesh safety barrier prevents direct contact with the viewing area glass, preventing burns
  • Millivolt ignition system keeps your fireplace working even without power
  • Built-in on/off switch and adjustable flame and heat control gives you customizable comfort
  • High heat ceramic glass front offers a safe, beautiful view of the fire
  • All Napoleon products are backed by a limited lifetime warranty
