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:
• Ensure exhaust gas is kept away from:
B windows
C doors
D ventilation intakes
• Install generator outdoors in an area that will not
accumulate deadly exhaust gas.
E soffit vents
F garage doors
• DO NOT install generator where exhaust gas could
accumulate and enter inside or be drawn into a
potentially occupied building or structure.
• By law it is required in many states to have a Carbon
Monoxide (CO) detector in operating condition in
your home. Carbon monoxide detector(s) A MUST
be installed and maintained indoors according to
the manufacturer’s instructions/ recommendations.
A CO monitor is an electronic device that detects
hazardous levels of CO. When there is a buildup of

WARNING Propane and Natural Gas are extremely flammable
and explosive, which could cause burns, fire or
explosion resulting in death, serious injury and/or
property damage.
LP gas is heavier than air and will settle in low areas.
Natural gas is lighter than air and will collect in high areas.
The slightest spark could ignite these fuels and cause an explosion.
DO NOT light a cigarette or smoke.
TO THE INSTALLER: Consult with the generator owner(s) and
convey any technical considerations that might affect their

The following general rules apply to gaseous fuel
system piping:
• Install the flexible steel fuel line B (supplied) between
the generator fuel inlet port A and rigid piping
to prevent thermal expansion or contraction from
causing excessive stress on the piping material.
n
The information below is provided to assist gaseous fuel
system technicians in planning installations. In no way
should this information be interpreted to conflict with
applicable fuel gas codes. Consult with your local fuel
supplier or Fire Marshall if questions or problems arise.
WARNING Propane and Natural Gas are extremely flammable
and explosive, which could cause burns, fire or
explosion resulting in death, serious injury and/or
property damage.
• Before placing the generator into service, the fuel system lines
must be properly purged and leak tested.
• No leakage is permitted.
NOTICE The supplied flexible steel fuel line is not to be installed
underground or in contact with the ground.
• The entire flexible steel fuel line must be visible for
periodic inspection and must not be concealed within
nor contact nor run through any wall, floor, or partition.
20
• 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 F where condensate is not likely to freeze.
• The piping should be of a material that conforms
to federal and local codes, rigidly mounted and
protected against vibration.
• A minimum of one accessible, approved manual
shutoff valve E shall be installed in the fuel supply
line within 6 ft (180 cm) of the home generator.
• Piping should be protected from physical damage
where it passes through flower beds, shrub beds, and
other cultivated areas where damage could occur.
• A manual fuel shut-off valve located in the interior of
the building.
• 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.
• 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.
Fuel Pressure
Both LP vapor and natural gas fuel supply pressure at the
generator’s fuel inlet port should be between the following levels
at full load with all gas appliances turned on and operating.
• NG is 3.5-7” W.C.
• LP is 11-14” W.C.
Air density is less at high altitudes, resulting in less available
engine power. Specifically, engine power will decrease 3.5%
for each 1,000 feet (300 m) above sea level and 1% for each
10° F (5.6°C) above 77°F (25°C). Generators located in these
conditions must have their transfer switch programmed
appropriately for this power decrease.
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.

Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.
Power Loss

• 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.
21
To configure the fuel system for LP use:
Fuel Conversion
1. Set generator’s system switch to OFF.
The engine of your home generator system is factory
calibrated to run on natural gas (NG). It may also be operated
on liquefied petroleum (LP) vapor. The LP Conversion Kit
(supplied) is required to convert the unit to LP vapor fuel.
LP fuel inlet pressure must be between 11 and 14 inches
water column at full load with all gas appliances turned on
and operating.
2. Remove 15 Amp fuse from control panel.
3. Remove roof, divider, side panels, exhaust panel and
muffler cover.
4. Change main jet in fuel mixer following instructions
provided in LP Conversion Kit.
5. Reinstall muffler cover, exhaust panel, side panels,
divider and roof.

C - 15 Amp Fuse — Protects the home 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).
26
D - System Switch — This two-position switch is the most
important control on the home 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.
E – MANUAL OVER-RIDE — Used to manually start and
stop the generator.
F - Digital Display — Displays running time in hours or
fault codes.
More information may be found in Controls in the

Final Installation Considerations
Engine Oil
NOTICE Any attempt to crank or start the engine before it has
been properly serviced with the recommended oil will result in
equipment failure.
• Refer to Maintenance in the operator’s manual for oil fill
information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
This engine is shipped from the factory pre-run and filled
with synthetic oil (API SJ/CF 5W-30). This allows for system
operation in a wide range of temperature and climate
conditions. Before starting the engine, check oil level as
described in Maintenance of the Operator’s Manual.
n
The use of synthetic oil does not alter the required oil change
intervals described in the Operator’s Manual.

Engine Adjustment
There are regional variances in the composition of natural
gas. Each home generator unit leaves the factory set for
NG operation. If the generator output voltage or frequency
measured during Initial Start-Up is outside the listed ranges,
the combustibility of the gas supplied at the installation
site may be substantially different from the fuel used at
the factory.
To adjust the engine for this difference, proceed as follows:
1. Remove four screws A that secure control box front
to enclosure to expose unit’s circuit breaker.
A
A
8. Turn utility service disconnect to transfer switch OFF.
After a short time delay, transfer switch will connect
to generator.
9. Load generator to full load.
10. After load stabilizes, frequency should be
above 57.0 Hz.
11. If frequency is below 57.0 Hz, slowly adjust the
governor until frequency is above 57.0 Hz.
12. Turn service disconnect to transfer switch ON.
Transfer switch will connect to utility power after
five minutes.
13. Push and hold MANUAL OVER-RIDE button on control
panel until engine stops.
14. After the engine has stopped:
• If an adjustment was made in step 11, repeat steps
2 through 7.

3. Ensure that the 15 Amp fuse is installed.
4. Set the generator’s main circuit breaker ON.
5. Set the generator’s system switch to AUTO.
6. Push MANUAL OVER-RIDE button on control panel.
When the engine starts, allow it to warm up for
five minutes.
7. Normal no load frequency is 62.0 to 62.5 Hz. If
adjustment is needed at no load, remove unit
side panels. Using needle nose pliers, bend spring
anchor tang B slowly up or down until frequency is
62.0 to 62.5 Hz.

If no load frequency falls out of the no load range shown in
step 7 after full load adjustment is made, contact Customer
Service at (888) 575-8226
15. Reinstall control panel into enclosure.

Operation
Automatic Operation Sequence
The generator’s control panel houses a logic control circuit
board. This control board constantly monitors utility power
source voltage. Should that voltage drop below a preset
level, control board action will signal the engine to crank
and start.
Utility Voltage Pickup Sensor
When utility source voltage is restored above a preset
voltage level, the engine is signaled to shut down.
Engine Cool-down Timer
Utility Voltage Dropout Sensor
• This sensor monitors utility source voltage.
• The timer will run for about one minute, then the
generator will stop.
• Minimum engine run time is 5 minutes.

• If utility source voltage drops below about 70 percent
of the nominal supply voltage, the sensor energizes
a 10 second timer. The timer is used to ‘sense’
brown‑outs.
• When the load is transferred back to the utility power
source, the engine cool-down timer starts timing.
n
The actual system operation is not adjustable and is
sequenced by sensors and timers on the control board,
as follows:
This sensor monitors utility power supply voltage. When that
voltage is restored above 80 percent of the nominal source
voltage, a time delay starts timing and the engine will go to
engine cool-down.
• Once the timer has expired, the engine will crank
and start.

Setting Exercise Timer
The home generator is equipped with an exercise timer that
will start and exercise the system once every seven days.
During this 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).
A button on the control panel is labeled “SET EXERCISE” (see
System Control Panel). The specific day and the specific
time of day this button is pressed is programmed into the
control board memory. This date and time is then used to
automatically initiate the system exercise cycle. The “SET
EXERCISE” legend on the control panel will flash until the set
exercise cycle is set.
To perform the Set Exercise procedure:
1. Choose the day and time you want your home
generator to exercise.
2. On that day and time, press and hold “SET EXERCISE”
for three seconds.
The “Set Exercise” display will illuminate then turn off
to confirm that the exercise timer has been set. Then
release the button.
The unit will crank and run the exercise cycle. During
the cycle, “Set Exercise” will illuminate.
Once the exercise cycle is complete, the unit will turn
off and “Set Exercise” will no longer be displayed.
The exercise cycle may be discontinued at anytime by
turning the System Switch to OFF.
3. The unit will then start and run it’s 20 minute exercise
cycle.

For example, if you press SET EXERCISE on Sunday morning
at 10:00 AM, the unit will run an immediate exercise cycle
and an exercise cycle every following Sunday at 10:00 AM
(+/- 1/2 hour).
“Set Exercise” will only work if the unit is in the AUTO mode
and this exact procedure is followed. The exerciser will need
to be re-set if the 15 Amp fuse is removed or changed, or if
the starting battery is disconnected.
If you want to change the day and time the unit exercises,
simply perform the “Set Exercise” procedure at the exact
weekday and time you want it to take place.
Generator will not exercise if timer is not set.
