What to check

  • Meter capacity, service pressure, and line size from the gas fitter
  • Heating value from the utility, which varies by region

Fuel figures are estimator-grade. A manufacturer fuel curve at your load and ambient beats any generic curve; verify the nameplate rating, the actual load fraction, and the delivered fuel price before you size a tank or promise a runtime.
