The cutting-edge combustion technique uses a catalytic combustor and unique bypass damper to incinerate fine particulates all the while providing more control over how your fire burns. The catalytic combustor helps create a controlled flame that allows a more even burn rate helping to:

• Reduce over-heated, uncomfortable rooms and the
  need to constantly adjust to the appliance.
• Give an extended burn period generally only seen
  in rural LEB models.
• Prolongs the life of your firebox that gives us the
  confidence to provide a market-leading 20-year
  firebox replacement warranty on our catalytic ULEB.
