LENNOX’ ELITE®SERIES
G60 Gas Furnace ◆80% AFUE

The Elite®Series G60 gas furnace surrounds you with quiet, cozy comfort
all season long. Its two-stage design accommodates two levels of heating:
high heat for extremely cold days, and low heat for mild days.
ENGINEERED FOR QUIET COMFORT AND EFFICIENCY
Because the G60 operates at low capacity about 80% of the time,
it provides quieter, more even heat distribution and regulates the
temperature to within as little as one degree of the thermostat setting.
And with an 80% efficiency rating, the G60 can reduce your energy bills
when compared with less efficient furnaces.
