All fossil fuel burning equipment, such as standby
generators, contains carbon monoxide (CO) gas in the
engine exhaust. CO gas is odorless, colorless and tasteless
and is unlikely to be noticed until a person is overcome.
CO gas can kill you so it is required that the following is
included as part of the installation:

Fuel Pipe Sizing
There are numerous on-line or otherwise-published
references for fuel pip sizing. For example, NFPA 54-Natural
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.

Grounding the Generator
Generator Power Connection
The home generator must be installed as part of a system
that includes a listed transfer switch, with neutral to ground
bonding at the transfer switch in accordance with installation
instructions. Unless mandated by local code, additional
grounding to earth at the generator is not required. Any
grounding at generator must use metal piercing lock
washers (or equal), UL listed terminals installed per terminal
supplier’s instructions, and comply with national electrical
codes and local requirements.
Using installer supplied minimum 300V, 6 AWG wire,
connect generator power output Line 1, Line 2, neutral and
ground to the corresponding Line 1, Line 2, neutral and
ground in the transfer switch.
Transfer Switch Communication
Using installer supplied #18 AWG twisted pair conductors,
no greater than 200 ft in length, connect Tx Rx and Tx Rx
GND from the generator terminal block to T/R and GND on
the transfer switch control board. When making connections,

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.
Initial Start-up (No Load)
The unit has been set-up for NG operation at the factory.
Fuel conversion, if needed, must be completed prior to
performing these steps. See Fuel Conversion.
Before operating the home generator or placing it into
service, inspect the entire installation carefully. Then begin
testing the system without any electrical loads connected,
as follows:
6. Listen for unusual noises, vibration or other indications
of abnormal operation. Check for oil leaks while engine
runs.
7. Let engine warm up for about 5 minutes to allow
internal temperatures to stabilize.
8. Check generator output at load side of circuit breaker.
Voltage should be 225 - 250 Volts, frequency should be
59.0 - 61.0 Hz.
1. Remove three screws (A) that secure control box cover
to enclosure to expose unit’s circuit breaker.
2. Connect an accurate frequency meter to line side of
generator’s main circuit breaker.
9. Check generator output between one generator
connection lug and neutral lug, then between other
generator connection lug and neutral lug. In both cases,
voltage reading should be between 112 and 125 Volts.
3. Set generator’s main circuit breaker to ON

Electronic Governor System
The engine electronic governor system allows for improved
control and increased generator performance compared
to mechanically governed systems. The result is smooth
TUFBEZꢇTUBUFꢀPQFSBUJPOꢀXJUIPVUꢀUIFꢀiIVOUJOHwꢀDPNNPOꢀUPꢀ
many mechanical governors. The system also reduces
speed variations under engine loading and unloading and
significantly reduces frequency fluctuation experienced when
the engine is under higher loads.
The electronic governor system is composed of a stepper
motor (B), stepper motor throttle control linkages (C), and
throttle side linkage (A). The control board contains a digital
controller that processes engine speed information and
sends appropriate commands to the stepper motor to control
the position of the engine throttle.
Since the electronic governing system controls the engine
throttle demand based upon generator load, the following
service codes and/or conditions may be related to an
electronic governing system issue:

tꢀ 6OTUBCMFꢀ/Pꢀ-PBEꢀ&OHJOFꢀ$POUSPM
While trouble shooting any of these conditions, a verification
of the electronic governor system can be initiated through
the control panel – advanced menu options – Electronic
Governor Check.
Electronic Governing Check:
The generator has an electronic governing check feature that
will turn on the stepper motor and move the throttle linkage
clockwise and counterclockwise within the throttle limits.
The test will rotate the stepper motor and move the throttle
arm between the wide open throttle and dead idle limits 4
times with a 2 second delay between each throttle sweep.
This will allow visual verification that the stepper motor is
functioning properly and the control linkages are connected.
The engine will not attempt to start during this test. If the
stepper motor does not move, or if a linkage binds, then
service may be required.

Setting Exercise Timer
Operation
The generator is equipped with an exercise timer. During the
exercise period, the unit runs for approximately 20 minutes
and then shuts down. Electrical load transfer DOES NOT
occur during the exercise cycle (unless an utility power
outage occurs).
Automatic Operation Sequence
The generator’s control board constantly monitors utility
voltage. Should utility voltage drop below a preset level, the
control board will signal the engine to crank and start.
The generator will only enter the exercise cycle if the unit is
in the AUTO mode and this exact procedure is followed.
When utility voltage is restored above a preset voltage level,
the engine is signaled to shut down.
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:
To set the exercise timer:
NOTICE The generator is set with a default exercise cycle
setting of Tuesday at 2:00 P.M, Central Time. To change the
cycle setting, proceed to the following steps:
