Tempstar® SmartComfort® DLX80
80% AFUE Furnace


Direct hot surface ignition system features an advanced silicon nitride igniter and in-shot burners for greater reliability.


Temperature limit control, reliable gas valve and induced draft motor all help ensure safe operation.


Solid pre-painted steel insulated cabinet with tight-fit door latch system, blower motor isolated behind a sealed door, and soft-mount rubber gaskets on key components lower operating sounds.


Two-stage redundant gas valve and two-speed induced draft blower adjust to the higher or lower settings when more or less heat is needed, then heated air is delivered by a PSC blower. The IIS 80 is also compatible with two-stage cooling, and its advanced dehumidification capability can reduce additional moisture in the air when you add a humidity-sensing thermostat to your system.

  • Energy-saving high efficiency operation of 97% AFUE.
  • 10-year no hassle limited warranty will provide a replacement unit if the heat exchanger should fail within the first ten years.
  • Lifetime limited warranty on the primary and secondary heat exchanger.
  • 10-year limited warranty on all functional parts.
