GASOLINE
When using gasoline, always use fresh, clean,
unleaded fuel. This engine is certifi ed to operate on
unleaded gasoline with a minimum octane rating of
86 or higher. Gasoline containing no more than 10%
ethanol is acceptable.
CAUTION: EQUIPMENT DAMAGE
Do not use unapproved gasoline, such as E15 or
E85. Do not mix oil in the gasoline. Use of unap-
proved fuels will damage the engine components
and void the engine warranty.
Use of fuels with content of ethanol greater than
shown above may cause starting and/or perfor-
mance problems. Always ensure that the fuel is
clean and free of all impurities.
WARNING: FIRE DANGER
Gasoline and its fumes are VERY explosive when
proper precautions are not taken.
Never use gasoline that has been stored for an ex-
tended period of time as the fuel will lose its volatile
properties and you will be left with varnish residue.
The varnish like substance will clog the carburetor
and will not burn properly.
The use of fuel additives, such as STA-BIL, or an
equivalent will minimize the formation of fuel gum
deposits. If a unit has been out of operation for an
extended period of time, it is best to drain old fuel
from the engine and replace with fresh fuel before
attempting to start.
NG FUEL INSTALLATION
The information in this instruction is offered to assist
you in providing the proper Natural Gas (NG) fuel
supply for your engine. This information is only pro-
vided to advise you of the engine’s requirements and
the decisions you must make. In no case should this
information be interpreted to confl ict with any local,
state or national code. If in doubt, always follow local
codes.
DANGER: FIRE - PERSONAL INJURY -
All fuel lines must be installed by a qualifi ed fuel
supplier
.
The fuel source should be as close as possible to
the outdoor operating location. This will reduce the
installation cost of fuel runs. Connect the fuel supply
line to the inlet of the fuel demand regulator on the
unit using a locally approved fl exible fuel line (see
table for recommended line size).
The pressure
supplied to the demand regulator must be 4 TO 6
OUNCES or 7 to 11 INCHES W.C. (water column).
The primary regulator at the fuel supply must be
capable of delivering the proper volume of fuel at this
pressure.
Have your local fuel supplier install a protected fuel
connection at the outside operating location. They
should also install a lockable fuel shut off valve at the
connection point. An approved fl exible fuel line must
be installed between the engine generator set and
the supply line.
DANGER: FIRE - PERSONAL INJURY -
The NG fuel supply line must always be shut off
when the engine is not running. Failure to do so may
allow fuel to leak at the unit.
INSTALLING THE FUEL LINE
DANGER: PERSONAL INJURY
Units that are intended to be run unattended MUST
have an electric fuel solenoid installed. This solenoid
MUST be wired to AUTOMATICALLY turn off the fuel
whenever the engine stops.
Unit location will determine the size of fuel line that
is required to supply the engine with a constant fuel
pressure. Refer to the tables below for fuel line size,
and recommended tank size. The line size from the
table below applies to the distance from the second
regulator to the demand regulator.
AMBIENT TEMPERATURE
Use 4-stroke motor oil that meets or exceeds the requirements for
API service classification SJ or later (or equivalent). Always check
the API service label on the oil container to be sure it includes the
letters SJ or later (or equivalent).
SAE 10W-30 is recommended for general use. Other viscosities
shown in the chart may be used when the average temperature in
your area is within the indicated range.
