Direct-vent appliances draw combustion air from the outdoors and exhaust its combustion products to the outdoors, eliminating the need for a standard chimney system. A glass panel in direct-vent units is critical to keeping the combustion system sealed from the home, maintaining high efficiency and indoor air quality. Direct-vent piping can go out the wall directly in back of the unit or terminate vertically above the roof. Various models differ.

 

 
  • Framing – Zero clearance to combustible framing.
  • Heated Air – Forced convection heated room air.
  • Radiant Heat
  • Burner – Advanced burner technology produces the most realistic flames in the industry.
  • Heat Exchanger – Cool room air is naturally drawn into the heat exchange chamber.
  • Flue Gas Outlet
  • Combustion Air Inlet
  • Heat Exchange – Efficient heat exchange system.
  • Optional Rear Exhaust – (selected models)
  • Sealed Combustion Chamber
  • Glass – High heat ceramic or tempered glass increases the radiant heat that is dispersed throughout the room. Save up to 30% on energy costs with radiant heat and zone heating.
  • Panels – Porcelain Reflective Radiant Panels further increases radiant heat. (Optional on selected models)
  • Advanced Ceramic – Burner System (selected models)
  • Blower – Optional air circulating variable speed blower with high temperature bearings increases efficient heating.
