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.
