SL297NVVARIABLE-SPEED, ULTRA-LOW NOX GAS FURNACE

High-efficiency comfort you can feel good about

The SL297NV ultra-low NOx gas furnace provides reliable comfort, while producing 65% lower NOx emissions than standard low NOx furnaces. So, while you’re staying cozy warm, you’re also helping to protect the environment.

ALL-AROUND COMFORT

With an efficiency rating of up to 97% AFUE* as part of a communicating system, the SL297NV can potentially save you hundreds of dollars per year in energy costs.

ENERGY-SAVING PERFORMANCE

EFFICIENCY INNOVATIONS

FINE-TUNED FUEL USEThe SL297NV operates at two different levels of heat output, so it maintains a consistent temperature in your home using as little fuel as possible. This helps you stay comfortable and reduces your utility costs.

STAINLESS STEEL SECONDARY HEAT EXCHANGER The secondary heat exchanger allows the furnace to achieve higher efficiency levels by capturing additional heat.

SMART CONTROLWhen combined with the iComfort® S30 ultra smart thermostat, the SL297NV adjusts your heating for energy savings based on your family’s routine.

DUAL-FUEL-CAPABLE Can be combined with a Lennox® electric heat pump for peak efficiency.

The SL297NV has earned the ENERGY STAR® certification, which means it meets or exceeds guidelines set forth by the U.S. Environmental Protection Agency.

CONSISTENT TEMPERATURESA variable-speed blower motor allows the SL297NV to constantly and efficiently adjust airflow speed and gently disperse even heat throughout your home. It also prevents loud blasts of air that can occur when a single-speed system starts up, providing quiet operation for enhanced comfort.

COMFORT INNOVATIONS

TWO-STAGE HEATINGThe SL297NV operates at a more efficient low capacity most of the time to maintain your set temperature, with extra capacity for chilly mornings or evenings.

LOW FAN SPEED By circulating air slowly and steadily in “FAN ON” mode, the SL297NV can control humidity levels and create continuous filtration for cleaner, healthier air.

SPECIAL SOUND-ABSORBING INSULATION Further reduces sounds for quiet operation.

*AFUE, or Annual Fuel Utilization Efficiency, is a measure of how much usable heat is generated when natural gas is burned in the furnace. The higher the AFUE, the more heat you’ll get from your natural gas, and the less gas you’ll have to use to stay warm.
