Fuel Factors
An important consideration affecting the entire installation is the type of fuel used by your generator. The system was factory tested and adjusted using either natural gas or liquid propane (LP vapor). For proper engine function, factors that are inherent to each of these fuels, your location and the duration of possible utility interruptions are important considerations in the following fuel guidelines:
t 6TFDMFBOESZGVFMGSFFPGNPJTUVSF PSBOZ particulate material. Using fuels outside the following recommended values may cause performance problems.
t *OFOHJOFTTFUVQUPSVOPOQSPQBOF -1 DPNNFSDJBM grade HD5 propane with a minimum fuel energy of 2500 BTUs/ft3 with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%.
Natural gas rating will depend on specific fuel but typical derates are between 10 to 20% off the LP gas rating.
