Reading the model number
ML is Lennox's Merit line, 1 means single-stage, 80 is the AFUE, and DF is downflow. 090 is the 88,000 BTU input, E is the high efficiency constant torque blower motor, 48 is the nominal add-on cooling size, B is the 17.5-inch cabinet, and K means the furnace is ready for Lennox refrigerant detection.
What it pairs with
Downflow coils with the same letter match the furnace's supply air opening, so you want a Lennox CK40CT, CK40DT, CK40HT, or CK40UT coil with B in its size code.
The AHRI Directory lists this furnace in certified systems with CK40CT, CK40DT, CK40HT, and CK40UT coils and Lennox EL15KC1, EL16KC1, EL18KCV, 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, 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.
Shipping and help
It ships from our Kansas City warehouse. Call (913) 364-0070, Monday to Friday, 9am to 5pm CST, and we'll help you confirm sizing and an AHRI-matched pairing before you order.
