About The Lennox ML180DF110E60CK

The Lennox ML180DF110E60CK is a Merit Series single-stage gas furnace rated 110,000 BTU input and 90,000 BTU output at 80% AFUE. It comes in a 21-inch C cabinet, installs downflow, and has a constant torque blower sized for 3 to 5 tons of add-on cooling.

Key specs

  • Heating: 110,000 BTU input, 90,000 BTU output, 80% AFUE, single-stage
  • Cabinet: C size, 21 inches wide, downflow
  • Blower: 1 hp constant torque motor, 990 to 2,410 cfm, for 3 to 5 tons of cooling
  • Temperature rise: 30 to 60°F

Reading the model number

ML is Lennox's Merit line, 1 means single-stage, 80 is the AFUE, and DF is downflow. 110 is the 110,000 BTU input, E is the high efficiency constant torque blower motor, 60 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

Downflow coils with the same letter match the furnace's supply air opening, so you want a Lennox CK40DT coil with C in its size code.

The AHRI Directory lists this furnace in certified systems with CK40DT 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, 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.
