Standby and overload ratings based on ISO3046.
2
All ratings are gross flywheel horsepower corrected to 77oF at an altitude of 328feet with no
cooling fan or alternator losses using heating value for NG of 1015 BTU/SCF.
3
Production tolerances in engines and installed components can account for power variations of
+/- 5%. Altitude, temperature and excessive exhaust and intake restrictions should be applied to
power calculations.
4
The preceeding pipe sizes are only suggestions and piping sizes may vary with temperature,
pressure, distance from supply and application of local codes. Gas must be available at
adequate volume and pressure for engine at the EPR.
