INSTALLATION
General Information
******************
***** WARNING *****
******************
Before proceeding with the installation be sure the
operation selector switch is in the stop position.
These engine generator sets are designed to be
mounted on a concrete pad outdoors only. As an
option a prefab pad may be used as long as proper
attention is paid to site preparation to insure the unit
will not move after installation. The transfer switch is
mounted next to your electrical entrance or distribution panel inside or outside the building. Consult a
qualified, licensed electrician or contractor to install
and wire the transfer switch. The installation must
comply with all national, state and local codes.
Before beginning the installation process check the
rating of the generator set and its transfer switch
rating. Be certain they can handle the intended
load and are compatible with the enterance voltage,
phase and current ratings. Plans for installation
should be prepared with proper attention to mechanical and electrical engineering detail to assure
a satisfactory system installation. The information
in this manual is offered only as a guide to finializing
your installation plans.
e. Always avoid hot mufflers, exhaust manifolds,
and engine parts. They can cause severe
burns instantly.
f. Installing a generator set is not a “Do-it-your self” project. Consult a qualified, licensed elec trician or contractor. The installation must com ply with all national, state, and local codes.
TESTING POLICY:
Before any generator is shipped from the factory, it
is fully checked for performance. The generator is
loaded to its full capacity, and the voltage, current
and frequency are carefully checked.
Rated output of generators is based on engineering
tests of typical units, and is subject to, and limited
by, the temperature, altitude, fuel, and other conditions specified by the manufacturer of the applicable
engines.
INTRODUCTION AND
DESCRIPTION
The package standby system includes all times
necessary for a completely automatic standby power
system as standard equipment.
DESCRIPTION
The package standby system is designed to automatically provide standby power to unattended
loads during electrical outages. Upon an interruption
of normal electrical service the packaged standby
system electrical control circuits will automatically
start the engine. The generator will produce electrical power and the Automatic Transfer Switch (ATS)
will automatically transfer the electrical loads to the
generator set. Upon restoration of normal electrical service the emergency transfer switch will sense
return of the normal commercial power. The Automatic Transfer Switch will retransfer the load back to
the normal commercial power source. The engine
control circuits will begin a cool-down cycle, after
which the fuel supply will be shut off and the engine
ignition system disabled.
These packaged standby systems consist ot two
major components:
1) AUTOMATIC TRANSFER SWITCH
A wall mounted ASCO 165 Automatic Transfer
Switch (ATS) designed for inside installation. The
transfer switch is UL1008 approved. A fourteen day
electronic exerciser circuit is installed in the ATS
as standard equipment. The ATS also contains the
power failure sensing circuitry necessary to start and
stop the engine generator set. The transfer switch is
also equipped standard with a 3 second start delay,
and a 15 second transfer delay to allow the engine
to warm up before transferring the load to the generator. When the line power is restored the ATS has
a 5 minute retransfer delay to allow the incoming utility to stabilize before transferring back to line power
and then an additional 1 minute engine cool down
delay before the engine shuts down. Read and
understand the ATS owners manual before installing,
servicing or operating the transfer switch.

2) ENGINE / GENERATOR
The engine generator set consists of a Honda, twin
cylinder, four cycle air cooled engine. The engine is
factory equipped to run on LP or NG fuel. The engine operates at 3600 rpm and frequency regulation
is maintained by the engine governor within 4 cycles
variation (62.5 Hz - 58.5 Hz) from no load to rated
load. The generator is a brushless, single bearing,
direct drive, rotating field design. The generator is
connnected to the engine’s tapered (quill) crankshaft
extension. The engine generator is mounted in a
drip-proof enclosure for outside installation. Connection boxes and terminal blocks are provided for
all customer connections (both AC output and DC
control). A customer supplied 12 volt 500 CCA (BCI
group 26) battery is required to complete the installation.
** NOTICE **
This unit will automatically transfer if a power outage
occurs while running in an exercise mode.

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 minimized.
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 special 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 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 instructions and information provided 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-generator 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 11 inches
W.C. (water column).
These fuel pressures are critical; failure to provide
the proper pressure can cause many problems ranging 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 adjustments.
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 operating 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 recommended tank size. For distances of 100 feet or
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 low pressure regulator is installed to further reduce
the fuel pressure to the required four (4) to six (6) oz.
operating pressure. This low pressure regulator
must be at least 10 feet from the engine generator set, any closer installation will require a
larger line be installed to provide a fuel reservoir.
This is also true for the single low pressure regulators, it should also be a minimum 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) regulator system is used on LP, 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 low pressure regulator. (Consult you local fuel supplier for your exact
requirements). The appropriate line size from the
table below is then installed from the low pressure
regulator to the generator set.
FEET SIZE OF PIPE
up to 25 FT* 3/4 “ Pipe
25 - 100 FT* 1” Pipe
over 100 FT* Use a two regulator
system.
* Allow an additional 3 feet for each standard
elbow. Do not use ‘street ells’ (restrictive).
NATURAL GAS (NG)
The primary regulator (fuel meter) on the building
should deliver the correct volume and pressure to
the generator set. This regulator must be sized to
deliver the required BTU’s to the generator set and
all other appliances in the building. If the primary
regulator (fuel meter) is a high pressure regulator then a low pressure regulator must be
installed to bring the pressure down to 4-6 oz.
(7-11 inches water column) of pressure. This low
pressure regulator must be at least 10 feet from
the engine generator set, any closer installation
will require a larger line be installed to provide a
fuel reservoir. If this is not done the demand regu-
lator on the unit and the pressure regulator in the
fuel line will interfere with each other. This regulator must be sized to accomidate the demand of the
generator set and any other appliance connected to
it. See table below for the correct size of pipe to be
installed.
FEET SIZE OF PIPE
up to 25 FT* 3/4 “ Pipe
25 - 100 FT* 1” Pipe
over 100 FT* Consult Factory
* Allow an additional 3 feet for each standard
elbow. Do not use ‘street ells’ (restrictive).
******************
***** 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 to hazardous fuel
leaks.
**** CAUTION ****
Be careful when sealing gas joints. Excessive sealing compound can be drawn into the solenoid, regu-
lator or carburetor causing an engine malfunction.
FUEL PRESSURE
LP & NG VAPOR FUEL Correct fuel pressure can-
not be stressed enough. The most common cause
for inoperative systems is an inadequate or incorrect fuel pressure. Performance of the engine is in
direct relation to the correctness of the fuel system.
Shown below is a diagram of a typical LP vapor fuel
installation. Notice the following tables give two
(2) different units of measuring fuel pressure. The
first and most accurate is the use of a simple water
manometer. A manometer is calibrated in inches of
water column. The second is with a pressure gauge
calibrated in ounces per square inch.
