Key specs

  • Heating: 60,000 BTU input, 47,000 BTU output, 80% AFUE, two-stage, 39,000 BTU input on low fire
  • Cabinet: B size, 17.5 inches wide, downflow
  • Blower: 1/2 hp variable speed motor, 600 to 1,350 cfm, for 2 to 3 tons of cooling
  • Temperature rise: 35 to 65°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, 80 is the AFUE, and DF is downflow. 060 is the 60,000 BTU input, N means it meets California's 14 ng/J NOx standard, V is the variable speed blower motor, 36 is the nominal add-on cooling size, and B is the 17.5-inch cabinet.

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 B in its size code.

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