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.

CleanFire Series Q&A

WoodMaster certified furnaces top the EPA Cord Wood Database for Overall Efficiency. This Overall Efficiency can be as high as 84% but depending on Heat Delivery rates, the efficiency can be up to 86% Higher Heating Value and 93% Lower Heating Value. Lower Heating Value is the preferred measurement in Europe.

Pushing the air through the firebox keeps the fan clean and eliminates time consuming and costly combustion fan repairs.

The Clean Reload feature puts the furnace in idle mode about 30 minutes before your planned reloading. This helps reduce smoke when you open the firebox door to add wood.

The heat exchanger can be easily inspected with the hinged rear door. When needed, simply remove the tension-fit turbulators and run the provided cleaning tools through the heat exchanger ripples.

With the smaller firebox, a bypass is unnecessary. This model has passed the safety listing without the bypass.

Easy Refire reserves enough wood in the firebox to help quickly and efficiently ignite the new wood load.
