LESS TIME TO FILL…MORE TIME FOR YOU

 

Constructed of titanium-enhanced stainless steel, the firebox has superior corrosion resistance and excellent heat transfer performance. This allows loading the firebox for longer burn times (in some cases up to 48 hours or more*) and burning some wood that is less than perfectly seasoned.

Central Boiler recommends burning seasoned wood when possible because dry wood burns better and provides more energy for heating your home. You’ll burn less wood, saving you more money and time. That is, after all, what you want your outdoor furnace to do. *Actual burn times vary based on wood types, moisture content, heat load and ambient temperature.


Features and Benefits

  • More heat from the wood – the RippleTop design maximizes the surface area of the firebox and the HeatLock Baffle traps the heat in the heat collection area.
  • Easy to load – the large, insulated steel door is ergonomically designed for easy opening and closing and insulated to lock in the heat.
  • Easy to operate – the automatic draft control opens and closes as needed to control the water temperature in the system.
  • Durable and long-lasting – steel siding and powder-coating paint provide unequaled fit and finish and withstand the elements of time.
  • Dual Fuel Ready option – All Classic models are available as a Dual Fuel Ready model (standard on the CL 7260 and Pallet Burner) that allows the furnace to be fitted with an optional fuel oil, natural gas, or propane burner.
