Features and Benefits

- Vent Cap – Design eliminates evaporation.
- High-Capacity Water Jacket – Provides an added safeguard compared to designs with lower water capacity. Rigorously tested to verify weld integrity.
- Patented Ripple Top™ Design – Increases heat transfer area in the firebox and absorbs radiant heat for increased efficiency.
- Large, Insulated Steel 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. Central Boiler’s Cam Loc® door closure ensures a tight seal each time the door is closed.
- 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%.
- Removable Swinging Baffles – Increases combustion efficiency and easily removed with no tools.
- Shaker Grates – Makes ash removal easy.
- Urethane Foam Insulation – Insulation is sprayed on and forms a 100% airtight seal around the water jacket.
- Patented HeatLock Baffle® – Secondary Heat Exchanger – With up to 36% more heating surface area than other brands, it traps more heat and gases for most complete combustion and heat extraction.
- Combustion Accelerator™ – The over-air tube provides air at the top of the Combustion Dome, accelerating combustion and improving combustion efficiency.
- Combustion Dome™ – Area at the front of the firebox where gases are trapped for more complete combustion.
- Cyclone Side Draft – Provides primary fan-forced adjustable air delivery controlled by actuators rather than solenoids.
- Ash Clean-Out Door – Easily remove ash during operation.
- Titanium-Enhanced Stainless Steel, Rectangular Firebox – Superior corrosion resistance and excellent heat transfer performance. Engineered for exceptional structure integrity and will not collapse like round designs can.
- Skid Base Framework – makes installation easy with or without cement foundation.
- Welded Steel Framework – heavy-gauge framework engineered for enhanced strength of side panels and roof.
- Insulated Chimney – Features a Type HT-listed, factory-built chimney that helps minimize condensation.
