Fuel use
| Fuel | Half load | Full load |
|---|---|---|
| Propane | 1.64 gal/hr | 2.21 gal/hr |
| Natural gas | 124 ft³/hr | 193 ft³/hr |
On propane, a 500-gallon tank filled to 80% holds about 400 gallons. That runs the Kohler 14RCA for about 244 hours (10.2 days) nonstop at half load, or about 181 hours (7.5 days) at full load. See how much propane a generator uses for other tank sizes.
On natural gas, the gas line and meter have to deliver the full-load figure, 193 ft³/hr, even if the generator rarely runs that hard. Installers size the pipe to it.
Kohler publishes propane use in cubic feet per hour. Gallons are converted at Kohler's 2,500 Btu per cubic foot and the EIA's 91,452 Btu per gallon.
