About The Lennox SL280UH090V36B

The Lennox SL280UH090V36B is a Dave Lennox Signature Collection two-stage gas furnace rated 88,000 BTU input and 70,000 BTU output on high fire at 80% AFUE. It comes in a 17.5-inch B cabinet, installs upflow or horizontal, and has a variable speed blower sized for 2 to 3.5 tons of add-on cooling.

Key specs

  • Heating: 88,000 BTU input, 70,000 BTU output, 80% AFUE, two-stage, 57,000 BTU input on low fire
  • Cabinet: B size, 17.5 inches wide, upflow or horizontal
  • Blower: 1/2 hp variable speed motor, 498 to 1,393 cfm, for 2 to 3.5 tons of cooling
  • Temperature rise: 40 to 70°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 UH is upflow/horizontal. 090 is the 88,000 BTU input, 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

Coils with the same letter physically match the furnace, so you want a Lennox coil with B 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, 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.
