Rheem 6 Ton R-454B Gas/Electric Package Unit, 125,000 BTU/h Heat — RGECYB072ADT12BAAAA0
The Rheem RGECYB072ADT12BAAAA0 is a 6-ton Commercial Renaissance Classic Series packaged gas/electric unit that combines R-454B air conditioning with two-stage natural gas heat in one factory-assembled rooftop cabinet. Wired for 460V 3-phase power, it delivers 68,500 BTU/h AHRI net cooling at 11.0 EER / 14.6 IEER and pairs it with a 125,000 BTU/h nominal gas furnace (97,200 BTU/h heating output at 81% steady-state efficiency). A two-stage scroll compressor, all-microchannel coils, factory refrigerant leak detection, and a stainless-steel two-stage heat exchanger make this convertible downflow/horizontal unit a complete heating-and-cooling solution for light-commercial buildings that want cooling and high-capacity gas heat from a single 460V 3-phase rooftop.
Is a 6-Ton / 125,000 BTU Gas Package Unit the Right Size?
This unit matches 68,500 BTU/h of net cooling with a 125,000 BTU/h gas furnace, so it has to be sized for two loads at once. On the cooling side, 6 tons typically suits roughly 2,400 to 3,600 sq ft of light-commercial space; on the heating side, the 97,200 BTU/h output (high-capacity heat) should be matched to the building's design heating load and climate.
Cooling load depends on insulation, ventilation, occupancy, glazing, and local design temperatures, while heating load depends on climate, envelope, and ventilation air. The two-stage gas valve runs first stage at about 70% of full fire for quieter, more even heat and better part-load efficiency, with a high-fire temperature rise range of 40–70°F. Size both sides from a commercial load calculation rather than floor area alone so the unit neither short-cycles in cooling nor over- or under-heats the space.
Ideal for: High-occupancy retail, assembly, and large open commercial zones on 460V 3-phase power, in colder climates that need high-capacity gas heat.

Frequently Asked Questions
What cooling and heating capacity does the RGECYB072ADT12BAAAA0 provide?
It delivers 68,500 BTU/h AHRI net cooling (11.0 EER / 14.6 IEER) and 97,200 BTU/h of gas heating output from a 125,000 BTU/h nominal, two-stage furnace at 81% steady-state efficiency. Size both the cooling and heating sides from a commercial load calculation.
What power does the RGECYB072ADT12BAAAA0 require?
It is wired for 460V, 3-Phase, 60 Hz and needs a 18 A minimum circuit ampacity with a 25 A maximum overcurrent protection device. If your panel is 208/230V, order the 208/230V version instead.
Is the furnace two-stage, and can it run on propane?
Yes. The gas furnace is two-stage with a stainless-steel heat exchanger and direct spark ignition; first stage runs at about 70% of full fire for quieter, more even heat. It ships for natural gas and can be field-converted to LP (propane) with the Rheem RXGJ-FP41 LP conversion kit.
Can I add an economizer for free cooling?
Yes. This unit is pre-wired for an economizer. The matching Rheem RXRD-01MCDBM3 downflow economizer with single-enthalpy control brings in outdoor air for free cooling when conditions allow, and installs on 3–6 ton RGECYB units.
Can this unit be installed downflow and horizontal?
Yes. Airflow is field-convertible between vertical downflow (for curbed rooftop openings) and horizontal side-flow, so the same unit works on a curb or a slab with side duct connections.
How is the 6-ton gas package different from the smaller sizes?
Besides its higher 68,500 BTU/h AHRI net cooling, the 6-ton uses a two-stage scroll compressor (the 3–5 ton use single-stage) and is rated 11.0 EER / 14.6 IEER rather than in SEER2. It is offered only in the 125,000 BTU/h gas-heat configuration.
