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.
1
Standby and overload ratings based on ISO3046.
2
All ratings are gross flywheel horsepower corrected to 77
o
F at an altitude of 328 feet with no cooling fan or alternator losses using heating value for NG of 1025
BTU/SCF (HHV) and for propane of 2490 BTU/SCF (HHV).
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. Engine maybe operated at : up to 1200 feet and 86°F without power deration. For sustained operation above
these conditions, derate by 2.5% per 1000 feet, and 1.5% per 10°F.

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.

Standby and overload ratings based on ISO3046.
2
All ratings are gross flywheel horsepower corrected to 77o
F at an altitude of 328 feet with no cooling fan or alternator losses using heating value
for NG of 1025 BTU/SCF (HHV) and for propane of 2490 BTU/SCF (HHV).

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. Engine maybe operated at : up to 1200 feet and 86°F without power
deration. For sustained operation above these conditions, derate by 2.5% per 1000 feet, and 1.5% per 10°F.
