1. Vent Cap: Design eliminates evaporation.

2. High Capacity Water Jacket: Receives multiple tests to ensure welding integrity. Certified high quality steel used - no mixed metals.

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 water temperature in system.

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 standard.

9. Rear Exhaust Outlet: Increases efficiency. 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. Traps heat in 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. (1/4” thick, formed ash pan on stainless steel models.)

Fan Draft option available for all models.

A dual fuel ready option is also available which allows the furnace to be fitted with a fuel oil, natural gas, or propane burner.
