Central Boiler Classic 6048NR Titanium Series

The Classic series of outdoor wood furnaces is designed for effortless loading and operation while delivering outstanding durability, quality, and performance.

Built with a titanium-enhanced stainless steel firebox, these furnaces offer exceptional corrosion resistance and superior heat transfer capabilities. This robust construction enables longer burn times and even allows for burning wood that isn’t perfectly seasoned.

For non-residential applications only.

Benefits and Options

• Enhanced Heat Output: The RippleTop design maximizes the firebox’s surface area, while the HeatLock Baffle captures and retains heat within the collection area.
• Effortless Loading: An oversized, insulated steel door is ergonomically designed for easy access and ensures that heat is efficiently retained.
• User-Friendly Operation: Automatic draft control adjusts airflow as needed to maintain consistent water temperature throughout the system.
• Long-Lasting Construction: Durable steel siding paired with powder-coated paint provides a superior finish that stands up to the elements.
• Dual Fuel Ready Option: Every Classic model can be upgraded to a Dual Fuel Ready configuration, allowing for the addition of an optional fuel oil, natural gas, or propane burner.

Key Features

• Vent Cap: Engineered to minimize evaporation.
• High-Capacity Water Jacket: Undergoes rigorous testing to ensure welding integrity.
• RippleTop Design: Increases the available heat transfer area and minimizes maintenance requirements.
• Large, Insulated Steel Door: Provides easy loading with its ergonomic design, and is insulated and powder-coated for enhanced durability.
• Automatic Draft Control: Thermostatically regulates the system water temperature for optimal performance.
• Skid Base Framework: Simplifies installation on various foundations—with only select models, like the CL 7260 and Pallet Burner, requiring a cement slab.
• Welded Steel Framework: Constructed from heavy-gauge steel for reinforced strength in the side panels and roof.
• Insulated Chimney: A factory-built, Type HT listed chimney designed specifically for wood-burning appliances, standard with two 4-foot sections.
• Rear Exhaust Outlet: Boosts efficiency by preventing leaks and corrosion common with roof-exiting chimneys, while reducing heat loss by over 50% and allowing for easy inspection.
• Water-Filled HeatLock Baffle: Creates a secondary combustion zone and traps heat in the firebox, engineered to withstand extreme temperatures without warping or burning out.
• Urethane Foam Insulation: Applied as a spray to form a 100% airtight seal around the water jacket.
• Rectangular Firebox: Reinforced with stay pins to maintain its shape, avoiding the collapse issues sometimes seen with round designs.
• Ash Pan: A durable, 3/8" thick, formed ash pan that’s designed for easy cleaning.

Fan Draft option available for all models.

Additionally, a Dual Fuel Ready option is available that allows the furnace to be fitted with an optional fuel oil, natural gas, or propane burner.
