- Heating: 80,000 BTU input, 78,000 BTU output, 97.5% AFUE, two-stage, 52,000 BTU input on low fire
- Cabinet: C size, 21 inches wide, upflow or horizontal (left or right)

- Temperature rise: 40 to 70°F on high fire, 25 to 55°F on low fire
Reading the model number
SL is the Dave Lennox Signature Collection, 2 means two-stage, 97 is the AFUE code (this model is rated 97.5%), and UH is upflow/horizontal. 080 is the 80,000 BTU input, N means it meets California's 14 ng/J NOx standard, V is the variable speed blower motor, 60 is the nominal add-on cooling size, and C is the 21-inch cabinet.
What it pairs with
Coils with the same letter physically match the furnace, so you want a Lennox coil with C in its size code, such as a CK40CT, CK40HT, or CK40UT.
The AHRI Directory lists this furnace in certified systems with CK40CT, CK40HT, and CK40UT coils and Lennox EL16KC1, EL18KCV, EL22KCV, ML13KC1, ML14KC1, and ML17KC2 air conditioners, plus EL16KP1, EL18KSLV, EL19KPV, EL21KLV, and ML14KP1 heat pumps. Your efficiency rating depends on the exact outdoor unit, coil, and furnace together.
Sizing and fit
Size the furnace from a Manual J load calculation. Filters and filter mounting aren't included, so plan for a filter rack.
Because it meets the 14 ng/J limit, Lennox approves it for the South Coast, San Joaquin Valley, and Bay Area air districts. It isn't certified for mobile homes, RVs, or outdoor installs.
Warranty and registration
HVAC USA is an authorized Lennox reseller, and everything we sell is new factory equipment. Your full Lennox warranty applies when a licensed, manufacturer-certified contractor installs your system and registers it within 60 days.
