  • 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.

  1. Vent Cap - design eliminates evaporation.
  2. High Capacity Water Jacket - is tested multiple times to ensure welding integrity.
  3. Ripple Top Design - for increased heat transfer area and lower maintenance.
  4. Large, Insulated Cast Iron Door - ergonomically designed with a large door for easy loading. Door is insulated for maximum efficiency. Door parts are powder-coated for increased paint durability.
  5. Automatic Draft Control - thermostatically controls the system water temperature.
  6. Skid Base Framework - makes installation easy with or without cement foundation. Only the CL 7260 and Pallet Burner require a slab.
  7. Welded Steel Framework - heavy-gauge framework engineered for enhanced strength of side panels and roof.
  8. Insulated Chimney - the chimney is a Type HT listed, factory-built chimney for wood-burning appliances. Two 4-foot chimney sections are standard.
  9. Rear Exhaust Outlet - increases efficiency and eliminates leaks and corrosion that competitors experience from chimneys that exit through the roof. Designed for easy inspection. Reduces heat loss by over 50%.
  10. Water-Filled HeatLock Baffle - creates secondary combustion area and traps heat in the firebox. Will not warp or burn out with extreme heat.
  11. Urethane Foam Insulation - insulation is sprayed on and forms a 100% airtight seal around the water jacket.
  12. Rectangular Firebox - engineered with stay pins. Will not collapse like round designs can.
  13. Ash Pan - 3/8" thick, formed ash pan is durable and easy to clean.
