• Hazardous voltage can cause severe injury or
death. Electrocution is possible whenever
electricity is present. Open the main circuit
breaker of all power sources before servicing
the equipment. Configure the installation to
electrically ground the generator set, transfer
switch and related equipment and electrical
circuits to comply with applicable codes and
standards. Never contact electrical leads or
appliances when standing in water or on wet
ground because these conditions increase the
risk of electrocution.
• The exhaust from this product is extremely hot
and remains hot after shutdown. High grass,
weeds, brush, leaves, or other combustible
materials, must remain clear of the exhaust.
Such materials may ignite and burn from the
heat of the exhaust system.

• The generator engine exhaust fumes contain
carbon monoxide, which can be DEADLY. This
dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness or
even death. The generator must be installed
properly, in strict compliance with applicable

The generator is supplied with an integral molded
plastic base for use as an installation pad. Use of this
base is intended to minimize installation cost by
eliminating the need for a poured concrete pad.
A pad of crushed gravel a minimum of three inches
thick is recommended as a base to set the generator on.
Compact the gravel and ensure that the pad is level in all
directions, making sure that the overall pad height is
greater than the surrounding grade with a slope to carry
water away from all sides of the pad. Pad dimensions at
least six inches larger than the base size in all directions
are recommended.
It is possible to use a standard concrete pad if
desired. When using this method, a lightly steel
reinforced pad a minimum of 2 inches thick, poured to
local codes is recommended. Ensure the pad extends
past the generator pallet and is high enough to promote
drainage of water away from the generator.
After preparing the base pad (C), position the
generator (A) directly on the pad , complete with the
wooden skids supplied for shipping. Remove the lag
bolts (B) fastening the wood to the pallet from all six
positions. Using a pry bar with a block of wood as a
pivot, carefully lift one end of the pallet and remove the
wooden skids from both that end and the center of the
pallet (D). Lower the pallet to the pad, then pry the other
end up and remove the skid from that end (E). Check
the generator with a level in all directions, placing
material under the base as required.
Although the weight of the generator is adequate to
prevent movement during normal operation, anchoring of
the generator is recommended. To anchor the generator
on a gravel pad, drive a minimum of four (4) spikes
through the anchoring tabs located on the outside
corners of the pallet. If a concrete pad is used, anchor
the pallet at the same points using appropriate concrete
fasteners.

• For fire safety, the generator must be installed
and maintained properly. Installation always
must comply with applicable codes, standards,
laws and regulations. Adhere strictly to local,
state and national electrical and building codes.
Comply with regulations the Occupational
Safety and Health Administration (OSHA) and
National Electrical Code (NEC) have
established.
• This generator is designed to be installed
outside only. Never install this unit inside any
room, enclosure, or basement. The generator
needs adequate cooling and ventilation for
continued proper and safe operation.

200-266710
When connecting the generator to a building
electrical distribution system, use of a transfer switch is
recommended to isolate the normal utility source from
the generator supply. By preventing backfeed of the
generator power into the utility lines during a utility power
outage, the switch provides a level of safety for electrical
line workers. An automatic transfer switch listed to
Underwriters Laboratories Standard 1008 performs this
function while also supplying a method to automatically
start and stop the generator set and transfer power to the
building electrical system from an appropriate source.
When planning for a transfer switch/generator
installation, it is necessary to know the method of
interconnection to the building system. As illustrated, it is
recommended to connect the generator to power only
circuits that are necessary during a power outage. When
following this method, the transfer switch feeds only the
necessary circuits. Another option is to connect the
transfer switch directly to the entire building electrical
distribution system. In this case, all circuits or loads must
be controlled to avoid overloading and possibly
damaging the generator set.
Switch selection is based on factors such as the size
of the building distribution system, available generator
power and required generator control system. Due to the
complex nature of electrical distribution systems, the
sizing, selection and installation of a switch is best
handled by a licensed electrician or qualified standby
generator dealer. Any switch installation must be
performed by a licensed electrician to the instructions of
the switch manufacturer and any applicable local,
regional or national codes.

• Hazardous "backfeed" voltage can cause
severe injury or death. Install a transfer switch
in standby power installations to prevent
connection of standby and other sources of
power. Electrical backfeed into a utility
electrical system can cause serious injury or
death to utility personnel working on
transmission lines.
• Do not try MANUAL operation of the transfer
switch until all power supplied to the switch has
been positively turned OFF. Failure to turn OFF
power supplied may result in extremely
dangerous and possibly lethal electrical shock
or arching.

Once the generator is anchored in its final position, it
is ready for electrical connections. The generator is
supplied with two terminal blocks for connection of three
distinct electrical circuits; main line output power, utility
power input and generator start signal. Main line output
power is the electrical output of the generator, utility input
powers the battery charger and optional block heater
devices and the generator start signal is the interface
with an Automatic Transfer Switch that allows the
generator to operate automatically upon a utility power
outage.
The output circuit of the generator is 4-wire, 240V,
rated for the amperage as shown on the generator
nameplate. Connection to the transfer switch requires
two leads, commonly referred to as "hot" leads (L1 & L2),
a neutral (N), and ground lead. Positions of these leads
are labeled on the main line output terminal block, also
shown in Fig. A. Select proper power output wire
sizes according to allowable ampacities given in
Table 310-16 of the latest revision of The National
Electric Code(NFPA 70). To connect the wires, strip
the insulation back approximately ½" from the end of the
wire, insert the stripped end into the terminal block, then
torque the terminal block screw to 35 in-lbs (4.0 N-m).

A receptacle is provided with the generator to power
the battery charger for reliable starting. It is also
intended to power an optional block heater if that option
is desired. Connection of this circuit to a power supply
that is only present when normal utility power is supplied
is recommended. By connecting the receptacle in this
fashion, it is possible to insure that neither the battery
charger or block heater are on while the engine is
running. Precautions are engineered into the generator
to prevent these occurances but connection of the circuit
in this fashion provides an additional fail-safe method of
engine and battery protection.
Input to the utility circuit is 3-wire, 120V, 15A.
Connections include a "hot" lead (L1), neutral (N) and
ground lead. Positions of the incoming wire connections
are labeled at the auxiliary connection block, shown in
Fig. B . Select proper utility supply wire size
according to allowable ampacities given in Table
310-16 of the latest revision of The National Electric
Code(NFPA 70). To connect the wires, strip the
insulation back approximately ¼" from the end of the
wire, insert the stripped end under the screw and washer
on the terminal block, then torque the terminal block
screw to 20 in-lbs (2.3 N-m).
When the control panel mode switch is placed in the
AUTO position, generator starting and stopping is
controlled by the opening or closing of a set of voltage
free contacts. Two wires from those contacts are
connected to the generator through the auxiliary
connection block shown in Fig. B. Use of a twisted pair of
stranded copper wire no smaller than AWG 18 gage is
recommended. To insure proper operation of the auto
start feature, use a transfer switch offering “close-to-run
control contacts. To connect the wires, strip the
insulation back approximately ¼" from the end of the
wire, insert the stripped end under the screw and washer
on the terminal block, then torque the terminal block
screw to 20 in-lbs (2.3 N-m).
NOTICE: A field-installed conductor is not required
to be separated from a field wiring terminal of a
different circuit when the field wiring is insulated for
the maximum voltage of either circuit and both
circuits are Class 2 or Class 3, or both circuits are
other than Class 2 or Class 3.

The engine driving the generator is engineered to
provide reliable power on either Liquefied Propane Vapor
(LPG) or Natural Gas. For proper operation on these
fuels, it is important to deliver gas with adequate energy
content, at sufficient pressure and flow rate. This
generator is designed to operate on Liquefied Propane
Vapor (LPG) with a minimum energy content of 2500
BTU per cubic foot or Natural Gas with a minimum
energy content of 1000 BTU per cubic foot. This
generator is designed to operate with a fuel pressure at
the inlet of the unit between 6 and 11 inches of water
column (4-6 ounces).
Required fuel flow rates for specific models are given
in the table below. To insure correct sizing of the piping
supplying fuel to the generator set, provide the flow and
pressure requirements of this section to a fuel supplier or
licensed plumber during the installation planning stage. If
the fuel supplier cannot guarantee delivery of fuel with
these properties, the generator may not perform as
advertised.
Due to differences in the energy content of fuel used,
it is necessary to derate the output of the generator when
connected to Natural Gas. Additionally, regional and/or
seasonal variations in the makeup of the fuel can further
affect output of the engine/generator system. When
using Natural Gas fuel with minimum properties as
defined, engine output can fall approximately 10% below
that of the same set using Propane Vapor.
Per the National Gas Code (NFPA 54 - ANSI
2223.1), a manual shutoff valve in the fuel supply line
to the generator is recommended.
FUEL REQUIREMENTS:
For the best operation of the unit, the fuels used
should have a minimum content of 1000 BTU’s per cubic
foot for Natural Gas (NG) and 2520 BTU’s per Cubic foot
for Liquid Propane vapor (LPG). Contact local fuel
supplier for local BTU content. Fuel supply pressures
must be between 4oz (6” H20 per square inch) and 6oz
(11” H20 per square inch) at the inlet to the unit.
After electrical connections are complete, the next
installation step is to connect a fuel supply to the unit.
The fuel inlet fitting supplied with the generator is male
3/4" NPT. To accommodate potential settling of the
generator relative to rigid supply pipeline, use of a
flexible line, provided by manufacturer, in the supply line
is suggested. When making connections, use only
materials rated for the fuel supplied and approved for use
by local, regional or national codes and/or regulatory
agencies.

To insure reliable starting in most weather
conditions, it is important to properly match a battery to
the requirements of the generator. The generator uses a
12 Volt, direct current, negative ground control system
powered by an automotive style lead acid battery.
Successful engine starting is dependent upon the
cranking speed of the engine, which in turn is affected by
the cranking capacity of the battery. When selecting a
battery, choose the model that provides the highest
available cold cranking amperes (CCA) within a given
size range, as specified by the Battery Council
International (BCI). The battery tray and cables supplied
with the generator are sized to accept a BCI Group 26
or 26R battery, with a minimum recommended rating of
450 CCA.
The next step in installation of the generator is
placement and connection of the engine cranking
battery. Provided battery cables are sized to accept a
BCI Group 26 or 26R automotive style battery. A
battery with a minimum of 450 CCA (cold cranking
amperes) in this size range is recommended to assure
reliable engine starting.

• Where electrolyte contacts the skin, wash it
off immediately with water.
• Where electrolyte contacts the eyes, flush
thoroughly and immediately with water and
seek medical attention.
• Spilled electrolyte is to be washed down with
and acid neutralizing agent. A common
practice is to use a solution of one pound
(500 grams) bicarbonate of soda to one
gallon (4 liters) of water. The bicarbonate of
soda solution is to be added until the
evidence of reaction (foaming) has ceased.
The resulting liquid is to be flushed with

• Use tools with insulated handles.
• Wear rubber gloves.
• Do not lay tools or metal parts on top of
batteries.
• Disconnect charging source prior to
connecting or disconnecting battery
terminals.
• Determine if the battery is inadvertently
grounded. When inadvertently grounded,
remove source of ground. Contact with any
part of a grounded battery is capable of
resulting in electrical shock. The risk of such
shock is reduced when such grounds are
removed during installation and

To access the battery and charger, remove the front
and back panels by inserting the key into the locks
located on top of the panel. and turn 1/4 turn
counterclockwise to unlock. Lift the panels up and out of
the base and set it aside.
Place the battery (A) on the base as shown in Fig G.
After the battery is set, begin attaching the battery
cables to the battery posts, starting with the positive (+),
or red, cable (B). Loosen the bolt (C) on the post clamp
slightly to allow the clamp to expand, then firmly push the
clamp onto the battery post marked positive (+) until the
top of the post extends past the top of the clamp. Rotate
the clamp around the post as required to insure the
clamp cannot contact any metal components, then
tighten the clamp bolt (C) until snug. Finally,slide the
post boot (D) down the cable and place it entirely over
the clamp.
Finish connecting the battery by placing the negative

negative (-). Push the clamp firmly over the post until the
post extends past the top of the clamp, then rotate the
clamp to avoid contact with any metal parts. Tighten the
battery clamp bolt (F) until snug.
The final step of battery installation is to verify proper
connection of all battery charger connections. A battery
charging system (G) is included with the
engine/generator set to maintain the battery charge
during extended periods of generator inactivity, therefore
providing consistent starting. A quick check of charger
connections will verify that factory connections are
correct so the charger can function as intended. Insure
that the charger is connected by checking to see that it is
plugged into a powered receptacle, and that the positive
(+) and negative (-) charger cables are connected to their
respective battery cables.
Install the panels back onto the generator by placing
the bottom of the panel onto the base and pushing it up
into place. Lock the panel by inserting the key into the
locks and turning 1/4 turn clockwise.
Once all connections are made, the final installation
step is verification of proper engine oil level. Check oil
level before start-up (see page 23 for instructions). The
unit is shipped with the proper type of oil in the
crankcase for operation above 40°F. Follow the engine
manufacturer’s recommendations for oil at temperatures
below 40°F. Check oil periodically to ensure that the unit
is properly lubricated. Follow the engine manufacturer’s
recommended service schedule.

A standby generator is an engine driven air cooled
system to convert the energy contained in either liquid
propane vapor or natural gas to electrical power. When
coupled with an automatic transfer switch to monitor for
failure of utility power, the unattended system can start,
stop and transfer between sources to insure a nearly
seamless supply of power. The generator is housed in a
weather resistant, sound attenuated enclosure for
outdoor installation only.
Before installing and starting the generator, become
familiar with the controls and operational features of the
generator. Know how the control panel operates, what to
expect when activating control panel switches and how
to shut the generator off in the event of an emergency.

A. Mode Buttons
The Mode Buttons are used to set the operating
state of the generator. Pressing the OFF button prevents
engine operation or stops the engine if it is already
running. Pressing the MANUAL button (center button)
immediately starts the generator. Pressing the AUTO
button sets the generator for unattended operation under
the control of properly matched automatic transfer
switch.
B. Auto LED
The Auto LED will be green when the controller is
placed in the Auto Mode.
C. Status Indicator LED’s
Status Indicator LED’s are provided to communicate
the status of the generator to the user. Under normal
running conditions, only the green Auto LED is lit.
Function of all other LED’s are described on page 21.
D. Utility Power Monitor LED
The Utility Power Monitor LED will illuminate green
when the Voltage Sensing detects that the Utility is
available.
E. Transfer Switch Monitor LED
The Transfer Switch Monitor LED will illuminate
Green when the transfer switch is in the normal position
and it will illuminate Red when the Transfer Switch is in
the Emergency position.
F. Generator Power Monitor LED
The generator power monitor LED will illuminate Red
when the Voltage Sensing detects that the Generator
source is available.
G. Generator Hour Meter
The Generator Hour Meter is provided to track the
total numbers of hours of operation. The hour meter
runs whenever the engine is running and the alternator is
producing electricity. Placing the main line circuit
breaker in the OFF position while the engine is running
does not stop the meter from counting hours.
Main Line Circuit Breaker
A Main Line Circuit Breaker is provided to protect the
generator from damage caused by electrical faults within
the attached electrical distribution system. It is also used
to isolate the output of the generator from the connected
electrical distribution system by moving the breaker
handle to the OFF position. Placing the breaker in this
position does not prevent startup of the generator.
Control Circuit Fuse
The Control Circuit Fuse provides protection against
damage from electrical faults. Replace the fuse only with
an equivalent size and style of fuse to prevent damage to
the control system.
Charging Circuit Fuse
The Charging Circuit Fuse provides protection to the
engine mounted alternator in the event of electrical faults
in the positive (+) battery circuit. Failure of this fuse
prevents charge from reaching the battery when the
generator is running, leading to early battery failure.
Replace the fuse only with an equivalent size and style of
fuse to prevent damage to the control system.

RUN MODES
There are three run mode options: Off, Manual and
Auto. When the Manual pushbutton is pressed the unit
will immediately start and the run indicator light will
illuminate. In Manual mode, the generator will continue
to run until the Off pushbutton is pressed to stop the unit.
At this point the “not in auto” light will illuminate and the
unit will not operate.
When the Auto pushbutton is pressed the unit will
enter automatic run mode, where the generator controller
and the transfer switch will control the operation of the
unit. In automatic run mode, the unit will automatically
start up and shut off when power failure occurs and to
exercise the unit.
When power failure occurs, a signal will be sent to
the generator to start a warm up cycle. After the warm up
cycle is completed, the transfer switch will allow the load
to be transferred to the generator until it senses that
regular utility power has been restored. When this
occurs, the transfer switch will remove the load from the
generator and a signal will be sent to the generator to
begin a cool down cycle. After the cool down cycle is
completed, the unit will stop running, but remain in the
automatic run mode.
The unit will also automatically start itself to ensure it
remains in good working order. Every 28 days the unit
will automatically start up without warning and run for 20
minutes before shutting down. The unit will remain in
automatic run mode after each exercise session.
Two methods are available to start the generator.
The automatic, or AUTO mode is for use with an
automatic transfer switch. With the control panel mode
switch set to this position, the generator waits for an
external signal to start. This signal is supplied by the
transfer switch when utility power is of unacceptable
quality. Since utility power can fail at any time, be aware
the generator can start unexpectedly whenever in the
AUTO position. Keep away from moving parts at all
times. Once utility power is once again acceptable, the
signal from the transfer switch is removed, the generator
shuts off, then returns to waiting for another signal to
start.
The other method for starting the generating is to
press the MANUAL position mode button. This mode is
intended for generator control during maintenance or if
an automatic transfer switch is not used. With the control
panel switch shifted to this position, the generator will
immediately attempt to start after a brief pause. Upon
starting, the generator runs until the switch is moved
from the MANUAL position, at which time the generator
will shut off.
To insure the generator starts without damaging the
starter motor, cranking of the engine is performed in a
cyclic manner. When the generator is started from either
the AUTO or MANUAL positions, the controller alternates
between 10 seconds of engine cranking, followed by 10
seconds of engine rest. If the engine starts during any of
the cranking periods, crank attempts are halted and the
controller begins monitoring for proper function of the
generator. In the event that three 10 second start
attempts occur without the engine starting, cranking
attempts are halted and the Overcrank light is lit.
After the engine is started and the generator is
producing electrical power, the controller begins
operation in a monitoring state. In this state, several
generator functions are continuously checked to ensure
proper operation of the generator. If functions are
determined unacceptable, a fault is declared, the engine
is shut down and a status light is lit to communicate the
reason for the shutdown.
When operating with the control panel switch in the
MANUAL position, the generator will continue to run until
a fault is declared or until the mode switch is moved to
the OFF position. Once the switch is shifted to the OFF
position, the engine is shut off.
When operating with the control panel switch in the
AUTO position, the generator continues to run until a
fault light is declared or the run signal is removed. Once
the signal is removed, the engine shuts down and the
controller returns to waiting for a start signal.
