CetdWeather Kit
if operating the generator below 30°F(-1°0), it is HIGHLY
RECOMMENDEDthat a Model 6231 Cold Weather Kit
(includes oil warmers and batterywarmer) be installed.
Theseitems areavailableatyour local servicing dealer.
Forcold weather areas(below 0°F (-18°C)) it is also
recommendedthat a BCl, Size75, wet bad-acid battery be
used of 630 CCAminimum.

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.
