Reading the model number
EL is Lennox's Elite line, 2 means two-stage, 80 is the AFUE, and UH is upflow/horizontal. 045 is the 44,000 BTU input, E is the high efficiency constant torque blower motor, 36 is the nominal add-on cooling size, and A is the 14.5-inch cabinet.
What it pairs with
Coils with the same letter physically match the furnace, so you want a Lennox coil with A 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.
