The Lennox EL280UH110E48CK is an Elite Series two-stage gas furnace rated 110,000 BTU input and 89,000 BTU output on high fire at 80% AFUE. It comes in a 21-inch C cabinet, installs upflow or horizontal, and has a constant torque blower sized for 3 to 4 tons of add-on cooling.
Key specs
- Heating: 110,000 BTU input, 89,000 BTU output, 80% AFUE, two-stage, 72,000 BTU input on low fire
- Cabinet: C size, 21 inches wide, upflow or horizontal
- Blower: 3/4 hp constant torque motor, 865 to 1,780 cfm, for 3 to 4 tons of cooling
- Temperature rise: 35 to 65°F on high fire, 25 to 55°F on low fire
Reading the model number
EL is Lennox's Elite line, 2 means two-stage, 80 is the AFUE, and UH is upflow/horizontal. 110 is the 110,000 BTU input, E is the high efficiency constant torque blower motor, 48 is the nominal add-on cooling size, C is the 21-inch cabinet, and K means the furnace is ready for Lennox refrigerant detection.
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 EL15KC1, 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.
This model doesn't carry the X low NOx code, and Lennox says this furnace series can't go in the South Coast and San Joaquin Valley 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.
