The unit’s main frame should be bolted solid to a four to
six inch thick cement pad.  The engine-generator is
mounted on a sub-frame which is isolated with special
shock mounts on the main frame.  This allows the engine-
generator to vibrate without affecting the control panel on
the main frame.

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.

The unit should be mounted to allow for ample working
room around it.  A general rule to follow is five (5) feet
clearance on all sides.  See NFPA Code 37 for additional
clearance  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 assist 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 making you aware of the
decisions you must make.  In no case should the instruc-
tions or information provided be interpreted to conflict with
any local, state or national codes.  If in doubt, always
consult your local fire marshal or gas supplier.

    *************
*****  WARNING  ****
    *************
FIRE HAZARD  - All fuel runs should be installed by a
licensed fuel supplier.

To connect the fuel line, locate the 3/4 inch NPT fuel inlet
fitting on the side of the enclosure.  This inlet is shipped
with a plastic cap plug installed to insure the fuel system
stays clean.

    *************
*****  WARNING  ****
    *************
FIRE HAZARD - DO NOT OVERTIGHTEN THE FUEL
LINE. THIS IS A TAPERED FITTING, OVERTIGHTENING
WILL CAUSE THE FITTING TO CRACK AND LEAK
FUEL.

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 11 inches W.C. (Water
column). These fuel pressures are critical; failure to
provide the proper fuel pressure can cause many prob-
lems ranging from a unit that will not start to causing
damage to the fuel system

.

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.

Line Size

Unit location will determine the size of fuel line that is
required to supply the engine with a constant fuel pres-
sure and volume.  Refer to the tables below for fuel line
size, fuel consumption and recommended tank size.  For
distances of 50 feet and over, a two regulator fuel system
is recommended.  This is accomplished by installing a
primary regulator at the tank which will reduce the tank
pressure down to 10 to 15 lbs.  A secondary regulator is
installed to further reduce the fuel pressure to the required
four (4) to six (6) oz. operating pressure.  This secondary
regulator must be at least 10 feet from the engine genera-
tor set, any closer installation will require a larger line be
installed to provide a fuel reservoir.   This is also true for
the single dual stage regulators, it should also be mini-
mum of 10 feet from the unit.   If this is not done the
demand regulator on the unit and the pressure regulator
in the fuel line will interfere with each other.

When the two (2) stage regulator system is used, a fuel
line size of 1/2 to 5/8 inch is generally adequate for
distances up to 300 feet from the primary to the second-
ary regulator.  (Consult your local fuel supplier for your
exact requirements.) The appropriate line size from the
table below is then installed from the secondary regulator
to the generator set.

    *************
*****  WARNING  ****
    *************
PERSONAL DANGER - Do not use galvanized pipe in
fuel line runs.  The galvanized coating can become
eroded and flake off, causing possible obstructions in the
regulator or fuel valve.  The results could range from
inoperative engine start  to hazardous fuel leaks.
