FlexBurn Technology

FlexBurn stoves burn with or without a catalyst and achieve 15% higher efficiency on low burns with the catalyst in place.

Start Up

  • Primary burn started and fueled by fresh air
  • Bypass damper is open

2-Stage Burn

  • Damper is closed once stove and flue are sufficiently hot, forcing smoke into the secondary combustion chamber
  • Additional air feeds combustion of gases for secondary burn

3-Stage Burn

  • With catalyst in place, increased efficiency and lower emissions result from a tertiary burning of gases and CO
  • The catalyst also enables combustion at much lower temperatures, extending burn times and saving on fuel costs



Save Money and Use Less Wood with a Catalyst

Increase your heating efficiency and lower your stove emissions, ensuring you get the most out of each load of wood.




Catalytic Performance

Catalysts are ceramic cartridges made up of honeycomb-shaped cells with a special metallic coating, which triggers a chemical reaction that converts smoke into water vapor, carbon dioxide and heat. This chemical reaction occurs at roughly half the temperature that is required to combust wood smoke naturally.

Why Use a Catalyst

Save Money

  • Achieve 15% higher efficiency on low burn

Less Pollution

  • Lower particulate emissions
  • Significantly lower CO emissions

Less Creosote Buildup

  • Fewer chimney cleanings

More Even Burn

Maintenance and Care

  • Clean a few times per season
  • Clean out fly ash by forcing air through the combustor with a vacuum or can of compressed air*
  • Avoid burning wet or unseasoned wood, wood with high salt content, trash or petroleum products
  • Typical life expectancy is five to eight years, with a three-year 100% warranty; prorated through six years

*Do not use an air compressor, which could damage the catalyst
