The FireStar combustion controller constantly monitors how the wood is burning and automatically adds air where and when it’s needed for the cleanest, most efficient combustion.

  • Easy Refire – saves the coal bed for quick, easy restarts
  • Burn Time Monitor – helps to estimate when you need to add woods
  • Clean Reload – reduces smoke when you open the firebox door to add wood
  • Text Alerts – be notified when it’s time to add wood

Super-heated gases enter the round chamber of the Afterburner and swirl in a turbulent vortex, creating a Fireball and allowing enough time for complete combustion to occur.

The patented vertical Easy View Heat Exchanger with hinged door provides full access without the use of tools.

With the titanium-enhanced stainless steel firebox, there is zero corrosion and a lifetime of use, no matter what kind of firewood you burn.
