SoftSound IIS 90 Two-Stage Gas Furnace                                               

Reliable  Direct Hot Surface Ignition System features an advanced silicon nitride igniter for years of reliable starts.                   

Durable  The RPJ III primary heat exchanger is made of corrosion-resistant weld-free stainless steel. The unique integrated ripple-edged design forces more heat to the outside surface area for higher efficiencies.

Heating On Demand  Two-stage redundant gas valve, two-speed induced draft blower assembly, and variable-speed motor operate normally at the lower stage and ramp up as needed.                          


Quiet  Enclosed burner, fully insulated cabinet, and solid door design result in quiet operation.


System Monitoring  State-of-the-art electronic controls monitor system operation and allow for advanced diagnostics, a timesaving tool for technicians.

  • Energy-saving high efficiency operation of  92% AFUE.
  • Two-stage operation system reduces temperature and humidity swings in the home by heating and cooling more evenly.
