Features & Benefits

Primary Air Delivery – Cyclone Side Draft provides primary fan-forced, adjustable air delivery controlled by actuators rather than solenoids.
Combustion Accelerator™ – An over-air tube provides air at the top of the Combustion Dome™, the area in the firebox where gases are trapped for more complete combustion. This air accelerates combustion and improves combustion efficiency. This makes starting and restarting the furnace super easy.
Shaker Grate for improved airflow and easy ash removal through the Ash Cleanout Door.
Titanium-enhanced stainless steel firebox is impervious to corrosion and designed to last a lifetime.
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.
Patented Ripple Top® – Design increases heat transfer area in the firebox and absorbs radiant heat.
Rear-Exit Chimney – The rear-exiting, easy-to-inspect, design eliminates leaks and corrosion that through-the-roof designs can experience.
Removable Swinging Baffles – Increase combustion efficiency and easily removed with no tools.
High-Density Spray Foam Insulation – The ultimate airtight, waterproof insulation that locks heat in.
Dual Fuel Ready – Easily add an optional fuel oil, natural gas, or propane burner (kit sold separately and will be available for purchase in the future).
FireStar® Ready – Wired and ready for a FireStar® controller module, which lets you stay connected to the furnace from anywhere in the world. The module will be available as an option in the future.
