ENGINE GENERATOR SET MOUNTING
WARNING - Personal Injury
The enclosures on these units can become very
hot adjacent to the exhaust areas. Special care
must be taken when installing these units to
insure that the risk of contact by people is mini-
mized.
The unit’s main frame should be bolted to a four to
six inch thick cement pad. The engine-generator is
mounted on a sub-frame which is isolated with spe-
cial shock mounts on the main frame. This allows
the engine-generator to vibrate without affecting the
control panel on the main frame. (See page 20).
Do not install any shock mounts between the base
frame and the concrete pad. Engine vibration will be
transmitted to the control panel causing erroneous
start/stop cycles and premature control failure.
These units should be mounted a minimum of
24” from a structure.
This will allow for ample
room to maintain and work on the generator set.
Units must be installed in accordance with all local,
state, and national codes. Consult your local agency
having jurisdiction for specific requirements.
FUEL INSTALLATION
The fuel supply should be as close as possible to the
engine. This will reduce the installation cost of fuel
runs. The information in this manual is offered to as-
sist you in providing the proper fuel for your engine.
However, this information is only provided to inform
you of the engine’s requirements and assist in mak-
ing you aware of the decisions you must make. In
no case should the instructions and information pro-
vided be interpreted to conflict with any local, state
or national codes. If in doubt, always consult your
local fire marshal, gas supplier or building inspector.

***** WARNING *****
******************
FIRE HAZARD - All fuel runs should be installed
by a licensed fuel supplier.
To connect the fuel line to the generator set you will
connect your incoming fuel line to the 3/4 inch NPT
fitting located on the left side of the engine-genera-
tor set. This fitting is shipped with a plastic plug
installed to insure the fuel system stays clean.
For all vapor fuel systems the delivery pressure of
the fuel to the fuel solenoid on the unit must be four
to six ounces psi (per square inch) or 7 to inches
W.C. (water column).
These fuel pressures are critical; failure to provide
the proper pressure can cause many problems rang-
ing from a unit that will not start to causing damage
to the fuel system.
These units are normally tested on Natural Gas and
will have a fuel line connected to the NG port on the
fuel outlet tee. If you are going to operate on LP you
will need to move the fuel line from the NG port to
the LP port on the fuel outlet tee. These two ports
have different orifice inserts installed in them, which
provide proper operation with no further adjust-
ments.
When moving the fuel line from one port to the other
be sure not to kink or bend the line. Use a large
sweeping curve as possible and never shorten the
fuel line. For proper operation the fuel line must stay
the same length as it was shipped.
INSTALLING THE FUEL LINE
** NOTICE **
The engine generator sets are properly adjusted
before they leave the factory. A tag is attached to
the unit that specifies the fuel, natural gas (NG) or
propane vapor (LP) that the unit was set up and
tested on.
NATURAL GAS or LP VAPOR PIPE SIZE
Size of pipe nomally required for generators operat-
ing on NATURAL GAS or LP VAPOR.
Unit location will determine the size of fuel line that
is required to supply the engine with a constant fuel
pressure and volume.
LIQUID PROPANE VAPOR (LP)
Refer to the tables below for fuel line size and rec-
ommended tank size. For distances of 00 feet or
over, a two regulator fuel system is recommended.
This is accomplished by installing a primary regula-
tor at the tank which will reduce the tank pressure
down to 0 to 5 lbs.
