gas line shutoff valves are OPENand that

fuel pressure is availablewhenever automatic

in is desired.

Power Loss

Air density is less at high altitudes, resulting in less available

engine power. Specifically, engine powerwill decrease3.5%

for each 1,000feet (300 meters) abovesealevel and 1% for

each 10° F(5.6°C) above77% (25°C). Makesure you and

your installer consider these factors when determining total

generator load.

Fuel Pipe Sizing

Thereare numerous on-line or otherwise-puNished

referencesfor fuel pip sizing. For example,NFPA54-Natural

FuelGasCode,2006 (item #: 320-6031-06) is a

common resource.

The installer should consider the specific gravity of gas and

compensate for a nominal amount of restriction from bends,

fittings, etc. if an unusual number of fittings, bends,or other

restrictions are used, referto federal andlocal codes

for guidance.
