Central Boiler Classic 4030NR Titanium Series

The Classic series outdoor wood furnaces are engineered for effortless loading and operation while upholding exceptional durability, quality, and performance.

Crafted from titanium-enhanced stainless steel, the firebox boasts outstanding corrosion resistance and excellent heat transfer efficiency. This design enables extended burn durations and even allows for the use of wood that isn’t perfectly seasoned.

For non-residential applications only.

Benefits and Options

• Maximized Heat Output: The innovative RippleTop design expands the firebox’s surface area, while the HeatLock Baffle captures and retains heat within the collection zone.
• Effortless Loading: A generously sized, insulated steel door is ergonomically designed for smooth opening and closing, effectively locking in heat.
• Simple Operation: An automatic draft control system adjusts airflow as needed to maintain the desired water temperature.
• Built to Last: Durable steel siding combined with powder-coated paint ensures a flawless finish that endures over time.
• Dual Fuel Ready Option: Every Classic model can be configured as Dual Fuel Ready (standard on the CL 7260 and Pallet Burner), allowing the installation of an optional fuel oil, natural gas, or propane burner.

Features

• Vent Cap: Specially designed to minimize evaporation.
• High-Capacity Water Jacket: Rigorously tested multiple times to ensure robust welding integrity.
• RippleTop Design: Enhances the heat transfer area while reducing maintenance needs.
• Large, Insulated Steel Door: Ergonomically designed for ease of loading, with insulation and powder-coated components that maximize efficiency and durability.
• Automatic Draft Control: Precisely regulates system water temperature via a thermostatic mechanism.
• Skid Base Framework: Simplifies installation on various foundations—with only the CL 7260 and Pallet Burner models requiring a cement slab.
• Welded Steel Framework: Constructed from heavy-gauge steel for enhanced strength in both the side panels and roof.
• Insulated Chimney: A factory-built, Type HT listed chimney for wood-burning appliances, featuring two standard 4-foot sections.
• Rear Exhaust Outlet: Increases overall efficiency by eliminating leaks and reducing the risk of corrosion common with roof-exiting chimneys; designed for easy inspection and reduces heat loss by over 50%.
• Water-Filled HeatLock Baffle: Creates a secondary combustion zone and retains heat in the firebox, engineered to withstand extreme temperatures without warping or burning out.
• Urethane Foam Insulation: Sprayed on to form a 100% airtight seal around the water jacket.
• Rectangular Firebox: Reinforced with stay pins to prevent collapse, unlike some round designs.
• Ash Pan: A robust, 3/8-inch thick, formed ash pan that is both durable and easy to clean.

Fan Draft option available for all models.

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