 • Installtheflexible,gaseoushose(supplied)between
the generator fuel inlet port and rigid piping to prevent
thermal expansion or contraction from causing
excessive stress on the piping material.
NOTE: Where local conditions include earthquake, tornado,
unstable ground, or flood hazards, special consideration
shall be given to increase strength and flexibility of piping
supports and connections.
 • Pipingmustbeofthecorrectsizetomaintainthe
required supply pressures and volume flow under
varying generator load conditions with all gas
appliances connected to the fuel system turned on
and operating.
 • Useapipesealantorjointcompoundapprovedfor
use with NG/LPG on all threaded fittings to reduce the
possibility of leakage.
 • Installedpipingmustbeproperlypurgedand
leak tested, in accordance with applicable codes
and standards.
Consider the following factors when planning to install the
fuel supply system:
 • Airdensityislessathighaltitudes,resultinginless
available engine power. See Power Decrease at High
Altitude or High Temperature in the operator’s manual.
 • Aminimumofoneaccessible,approvedmanualshutoff
valve shall be installed in the fuel supply line within 6 ft
(1.8 m) of the residential generator. A union or flanged
connection shall be provided downstream from this
valve to permit removal of controls.
 • BothLPvaporandnaturalgasfuelsupplypressure
at the generator’s fuel inlet port should be between
7 to 11 inches of water (in. W.C.) at full load with all
gas appliances turned on and operating.
The generator unit has been factory load tested to run on
either natural gas or LP vapor fuel. The unit can be converted
from natural gas to LP vapor or vice versa using two people
and special tools. See Fuel Conversion, later in this manual.
It is recommended that the fuel connection incorporate the
following components:
 • Aminimum10ft.(3m)sectionofgaspipebetween
the primary fuel regulator and the generator fuel inlet
connection (acts as accumulator for high block loads).
 • Amanualfuelshut-offvalvelocatedintheinteriorof
the building.
 • Amanualfuelshut-offvalvelocatedoutsidethe
building, just before the generator unit.
 • Wheretheformationofhydratesoriceisknownto
occur, piping should be protected against freezing. The
termination of hard piping should include a sediment
trap where condensate is not likely to freeze.
 • Amanometerportshouldbeprovided.
CAUTION The supplied flexible gaseous pipe is not to
be installed underground or in contact with the ground.
The entire flexible gaseous pipe must be visible for •
periodic inspection and must not be concealed within nor
contact nor run through any wall, floor, or partition.
WARNING Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe
burns or death.
Before placing the generator into service, the fuel system •
lines must be properly purged and leak tested.
No leakage is permitted.•
12
The manometer port permits temporary installation of
a manometer to ensure that the engine receives the
correct fuel pressure to operate efficiently throughout its
operating range.
When the initial test runs are completed, the manometer
is removed and the port is plugged. A typical final fuel
connection assembly is shown here, where (A) is the fuel
supply and (B) goes to the generator.
Fuel Pipe Sizing
There are numerous on-line or otherwise-published
references for fuel pipe sizing. For example, NFPA 54 -
National Fuel Gas Code, 2006 (Item #: 320-6031-06) is a
common resource. The installer should consider the specific
gravity of gas and compensate for a nominal amount of
restriction from bends, fittings, etc. If an unusual number of
fittings, bends, or other restrictions are used, refer to federal
and local codes for guidance.

System Connectors
Low voltage connections to signal fault contacts, transfer switch communication, remote LED and auxiliary 12VDC power are
made via a removable ten-pole connector plug. Compare this illustration with your generator to familiarize yourself with the
location of these connections. Count down to the proper pin location on the control board since visual alignment with the
decal can be misleading:
A - 10 Pole Connector Plug
B - Fault Contacts Use NO, COM and NC to hook up a
siren, light, etc. to alert you in case of a fault. Contacts
reverse state (NO goes to NC and vice versa) upon a
fault condition.
C - Transfer Switch Communication — Connect to transfer
switch control board for communication interface using
18AWG copper twisted pair wire.
D - Remote LED Output — Use this to hook up the remote

Generator AC Connection System
A single-phase, three-wire AC connection system is used
in the residential generator. The stator assembly consists
of a pair of stationary windings with two leads brought out
of each winding. The junction of leads T2 and T3 forms the
neutral lead, as shown schematically and as wiring diagram
below. A complete schematic and wiring diagram can be
found later in this manual.
NOTE: Neutral is not bonded to ground at generator.
Grounding the Generator
Ground the generator per applicable codes, standards and
regulations. There are two generator GND lug locations.
The one inside the alternator junction box next to the circuit
breaker is the primary lug and should suffice for most
applications. The second generator GND lug is located on the
frame below the generator circuit breaker cover and should
ONLY be used for a ground rod located at the generator, if
required by local codes. See Controls for location.
Utility Circuit Connection
“240VUtilityCircuit”leadsmustberoutedinconduit.The
“240VUtilityCircuit”leadsdeliverpowertothegenerator’s
circuit board and water heater. This power also charges
the starting battery. When power on these leads is lost, the
generator will start.
Using installer-supplied minimum 300V, 14 AWG copper
wire, connect each ten-amp fuse terminal in the alternator
junction box to the ten-amp fuse terminals in the automatic
transfer switch.
When making connections, obey wire type and torque
specifications printed on the circuit breaker and neutral/
ground connector.
Fault Detection System
The generator may have to run for long periods of time with
no operator present. For that reason, the system is equipped
with sensors that automatically shut down the generator
in the event of potentially damaging conditions, such as
low oil pressure, high temperature, over speed, and other
conditions. Refer to Fault Detection System in the Operator’s
Manual for more detailed information.
The owner will use the remote LED indicator to observe the
status of the residential generator system. The remote LED
will turn on and off in a series of blinks if certain faults are
detected in the generator system. Consult with the owner
for a convenient location. Locate the electrical box in an
area visible by the home owner such as near a garage door
opener or security control panel.
To install the remote LED indicator:
1. Push the LED through the mounting plate from the
front until it snaps in place.
IMPORTANT: The LED is polarity sensitive.
2. Using provided 10 pole connector and installer-supplied
minimum 18AWG wire, connect the remote LED to the
generator control board +LED and GND connection.
Use wire nuts to attach wire to LED leads.
3. Attach mounting plate to installer-supplied
electrical box.

System Control Panel
The residential generator control panel, located inside the
generator housing, is shown below.
Brief descriptions of the controls used during installation are:
A - Circuit Breaker Must be ON to supply power to the
transfer switch. Breaker enclosure includes removable
bottom panel to assist with conduit connections.
B - SET EXERCISE Used to set exercise cycle start time.
C - MANUAL OVER-RIDE Used to manually start and stop
the generator.
D - 15 Amp Fuse — Protects DC control circuits.
E - System Switch Switches modes to OFF or AUTO.
F - Digital Display Displays running time in hours or
fault codes.
See Controls in the operator’s manual for more information
System Switch
This two-position switch is the most important control on
the residential generator and is used as follows:
 • AUTO”positionisthenormaloperatingposition.If
a utility power outage is sensed, the system will start
the generator. When utility power is restored, lets the
engine stabilize internal temperatures, shuts off the
generator, and waits for the next utility power outage.
 • OFF”positionturnsoffrunninggenerator,prevents
unit from starting and resets any detected faults.
15 Amp Fuse
Protects the generator DC control circuits. If the fuse has
‘blown’ (melted open) or was removed, the engine cannot
crank or start. Replace the fuse using only an identical
ATO 15A fuse. One spare fuse is supplied with the unit.
If fuse was blown or removed, you will need to reset the
exercise timer (see Setting Exercise Timer).
Final Installation Considerations
Engine Oil
The engine is shipped from the factory pre-run and filled
with non-synthetic oil (API SL 10W-30). This allows for
system operation in a wide range of temperature and climate
conditions. Before starting the engine, check oil level and
ensure that engine is serviced as described in the engine
operator’s manual.
Coolant System
The engine is shipped from the factory filled with a
50-50 mix of automotive (Dex-Cool™ orange) anti-freeze
and water. This will provide optimum year round protection
against freezing, boiling and corrosion. The coolant system
incorporates a water heater that operates when ambient
temperature is below 80ºF AND utility power is present at the
transfer switch. Periodically check coolant level as described
in the engine manual.

NOTICE Any attempt to crank or start the engine before
it has been properly serviced with the recommended
coolant or oil will result in equipment failure.
Refer to • Maintenance in the operator’s manual and engine
manual for coolant and oil fill information.
Damage to equipment resulting from failure to follow this •
instruction will void engine and generator warranty.

make sure the NEGATIVE cable is connected last.
Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.
Initial Start-up (No Load)
Before operating the generator or placing it into service,
inspect the entire installation carefully. Then begin testing the
system without any electrical loads connected, as follows:
NOTE: Unit has been set-up for NG or LP vapor operation at
the factory. Fuel conversion, if needed, must be completed
prior to performing these steps.
1. Connect an accurate AC voltmeter and a frequency
meter to check generator output at load side of
circuit breaker.
2. Set generator’s circuit breaker to its ON
(closed) position.
3. Confirm 15 Amp fuse is installed in system
control panel.
4. Set generator’s system switch to AUTO.
5. Push and hold MANUAL OVER-RIDE button on control
panel for about six seconds. Engine will start.
NOTE: When the generator is started for the very first time, it
will require that air in the gaseous fuel lines be purged. This
may take a few minutes.
6. Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil or coolant leaks
while engine runs.
7. Let engine warm up for about five minutes to allow
internal temperatures to stabilize.
8. No-load voltage should be 239 - 244 Volts, frequency
should be 59.8 - 60.2 Hz.
NOTE: If AC voltage is outside these ranges, perform the
generator adjustment, Steps 11 and 12 below.
9. Check generator output between one of the generator
connection lugs and the neutral lug, then between the
other generator connection lug and the neutral lug. In
both cases, voltage reading should be 117 - 123 Volts.
IMPORTANT: DO NOT proceed until you are certain that
generator AC voltage is correct and within the stated limits.
Generator frequency is fixed and not adjustable.
10. If voltage and frequency values are correct, proceed to
step 13.
11. Connect voltmeter as described in step 1 above.
12. While observing voltmeter, adjust alternator voltage
control (A) for 240 volts. DO NOT adjust either of the
other alternator controls.
13. Push and hold MANUAL OVER-RIDE button on control
panel until engine stops.
14. Install alternator circuit breaker enclosure cover.
