Save These Instructions The manufacturer
suggests that these rules for safe operation
be copied and posted near the units installation site. Safety should be stressed to all
operators and potential operators of this
equipment.
Study these SAFETY RULES carefully before installing, operating
or servicing this equipment. Become familiar with this Owners
Manual and with the unit. The generator can operate safely,
efficiently and reliably only if it is properly installed, operated and
maintained. Many accidents are caused by failing to follow simple
and fundamental rules or precautions.
• Adequate, unobstructed flow of cooling and ventilating air
is critical to correct generator operation. Do not alter the
installation or permit even partial blockage of ventilation
provisions, as this can seriously affect safe operation of the
generator. The generator MUST be installed and operated
outdoors only.
• Keep hands, feet, clothing, etc., away from drive belts, fans,
and other moving or hot parts. Never remove any drive belt or
fan guard while the unit is operating.
CALIFORNIA PROPOSITION 65 WARNING

• When working on this equipment, remain alert at all times.
Never work on the equipment when physically or mentally
fatigued.
• Inspect the generator regularly, and contact the nearest Dealer
for parts needing repair or replacement.
• Before performing any maintenance on the generator,
disconnect its battery cables to prevent accidental start up.
Disconnect the cable from the battery post indicated by a
NEGATIVE, NEG or (–) first, then remove the POSITIVE, POS
or (+) cable. When reconnecting the cables, connect the
POSITIVE cable first, the NEGATIVE cable last.
• Never use the generator or any of its parts as a step. Stepping
on the unit can stress and break parts, and may result in
dangerous operating conditions from leaking exhaust gases,
fuel leakage, oil leakage, etc.
CARBON MONOXIDE HAZARDS
• The engine exhaust fumes contain carbon monoxide, which
can be DEADLY. This dangerous gas, if breathed in sufficient
concentrations, can cause unconsciousness or even death.
Do NOT alter or add to the exhaust system or do anything that
might render the system unsafe or in noncompliance with
applicable codes and standards.
• Install a battery operated carbon monoxide alarm indoors,
according to manufacturer’s instructions/recommendations.
ELECTRICAL HAZARDS
• All generators covered by this manual produce dangerous
electrical voltages and can cause fatal electrical shock. Utility
power delivers extremely high and dangerous voltages to
the transfer switch as does the standby generator when it
is in operation. Avoid contact with bare wires, terminals,
connections, etc., while the unit is running. Ensure all
appropriate covers, guards and barriers are in place, secured
and/or locked before operating the generator. If work must
be done around an operating unit, stand on an insulated, dry
surface to reduce shock hazard.
• Do not handle any kind of electrical device while standing
in water, while barefoot, or while hands or feet are wet.
DANGEROUS ELECTRICAL SHOCK MAY RESULT.
• The National Electrical Code (NEC) requires the frame and external
electrically conductive parts of the generator to be connected to
an approved earth ground. Local electrical codes also may require
proper grounding of the generator electrical system.
• After installing this home standby electrical system, the
generator may crank and start at any time without warning.
When this occurs, load circuits are transferred to the STANDBY
(generator) power source. To prevent possible injury if such
a start and transfer occur, always set the generator’s AUTO/
OFF/MANUAL switch to its OFF position before working on
equipment and remove the 7.5A fuse from the generator control
panel.
• In case of accident caused by electric shock, immediately shut
down the source of electrical power. If this is not possible,
attempt to free the victim from the live conductor. AVOID DIRECT
CONTACT WITH THE VICTIM. Use a nonconducting implement,
such as a dry rope or board, to free the victim from the live
conductor. If the victim is unconscious, apply first aid and get
immediate medical help.
2
• Never wear jewelry when working on this equipment. Jewelry
can conduct electricity resulting in electric shock, or may get
caught in moving components causing injury.
FIRE HAZARDS
• For fire safety, the generator must be installed and maintained
properly. Installation must always 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) has established. Also, ensure that the
generator is installed in accordance with the manufacturer’s
instructions and recommendations. Following proper
installation, do nothing that might alter a safe installation and
render the unit in noncompliance with the aforementioned
codes, standards, laws and regulations.
• Keep a fire extinguisher near the generator at all times.
Extinguishers rated “ABC” by the National Fire Protection
Association are appropriate for use on the standby electric
system. Keep the extinguisher properly charged and be
familiar with its use. Consult the local fire depar tment with any
questions pertaining to fire extinguishers.
EXPLOSION HAZARDS
• Do not smoke around the generator. Wipe up any fuel or oil
spills immediately. Ensure that no combustible materials are left
in the generator compartment, or on or near the generator, as
FIRE or EXPLOSION may result. Keep the area surrounding the
generator clean and free from debris.
• Gaseous fluids such as natural gas and liquid propane (LP)
gas are extremely EXPLOSIVE. Install the fuel supply system
according to applicable fuel-gas codes. Before placing the
home standby electric system into service, fuel system
lines must be properly purged and leak tested according to
applicable code. After installation, inspect the fuel system
periodically for leaks. No leakage is permitted.

1. Both natural gas and LP Vapor are highly volatile substances,
so strict adherence to all safety procedures, codes, standards
and regulations is essential.
Gas line connections should be made by a certified plumber
familiar with local codes. Always use AGA-approved gas pipe
and a quality pipe sealant or joint compound.
Verify the capacity of the natural gas meter or the LP tank in
regards to providing sufficient fuel for both the generator and
other operating appliances.
2. Most applications will require an external manual full flow
shutoff valve on the fuel line.
3. Where the gas line is to enter the generator enclosure. Install
a 3 - 5“ long piece of ½” black iron pipe threaded at both
ends (Not provided). Thread one end into the generator fuel
regulator using the reducing bushing provided. On the other
end of the pipe thread a ½” standard pipe Tee as shown (Not
provided).
6. When connecting the gas line to the generator, use the
provided section of UL Listed or AGA-approved flexible fuel
line in accordance with local regulations. The purpose of the
flexible fuel line is to ensure that vibration from the generator
does not cause a gas leak at one of the connection points, so
it’s important that the line be installed with as few bends as
possible.
7. Never bend the flexible fuel line to avoid using an elbow.
Bending the flexible line decreases its ability to absorb
vibrations and defeats its purpose as well as constricts the
actual fuel flow.
8. After checking for leaks, check the gas pressure at the
regulator to make sure there’s enough pressure for proper
generator operation.
The local gas supplier is responsible for ensuring adequate
pressure, so if the pressure is too low, or if it’s greater than
14 inches of water column, contact the gas supplier.
Correct static fuel pressure should be:
• Natural Gas = 5-7 inches water column
• LP = 10-12 inches water column
Measure fuel
pressure here.
9. When finished checking the gas pressure, close the manual
shutoff valve.
4. Make sure the center leg of the Tee is pointing straight down
when fully tightened onto the pipe.
5. Thread a 3 – 4” long piece of ½” black iron pipe threaded
at both ends (not provided) into the Tee Fitting. Fully tighten.
Thread a ½” Pipe cap (not provided) to the other end of the
pipe. Fully tighten. This downward pointing pipe will serve as
a water and sediment trap and should be periodically emptied
once the generator is in service.

1. Electrical Connections to the generator are to be made inside
the main output circuit breaker panel. The connections will
consist of the following:
• 2 x Ungrounded conductors – Minimum wire size use 75
Deg C, 300V wire, 10AWG Copper.
• 1 x Grounded Conductor - Minimum wire size use 75 Deg
C, 300V wire, 10AWG Copper.
• 1 x Equipment Grounding Conductor - Minimum wire size
use 75 Deg C, 300V wire, 10AWG Copper.
• 6 x Control Wires – Use 75 Deg C, 300V wire, 14AWG
Copper.
NOTE:
Either use different colored wires or identify both ends of the
wires for easy connection of all wires to the Transfer Switch.
NOTE:
Local codes may require the control wires to be run in a separate conduit than the power wires.
• Use Class 1 wiring methods.
• These conductors should be fed through ¾” Flexible Liquidtight conduit for easy connection to the generator.
2. Remove the dead front plate from the output circuit breaker
panel. Retain fastener and external tooth washer for
reassembly.
5. Support the conduit connector plate up towards the output
circuit breaker. Make all the required wiring connections to the
Circuit breaker, Neutral Bar, Ground bar and Terminal strips
as described on the decal on the back side of the dead front
plate.
NOTE:
In order to maintain separation of circuits, the DC control wires
must be separated from the AC control wires. A piece of fiberglass sleeving has been provided in the manual kit to achieve
this. Slide the sleeving over the AC wires OR the DC wires, but
not both. Sleeving should extend over the wires from the conduit
connector in the conduit plate up to the terminal blocks.
3. Remove the conduit connector plate from the output circuit
breaker panel. Remove the plastic hole plug from the conduit
connector plate.
4. Pass all wires through hole in conduit connector plate, insert
conduit connector, and place lock nut onto conduit connector.

6. Once all connections are made, reattach the conduit
connector plate to the output circuit breaker panel making
sure no wires are trapped behind the panel.
7. Reattach the dead front plate to the output circuit breaker
panel with hardware removed in Step 1. Make sure to
reconnect the grounding wire.
8. Insert the padlock hasp that is supplied loose with the
generator through the slot in the dead front plate. Push the
padlock hasp back until it clicks and locks into place.
The correct size battery for this generator that will fit easily and
provide the required star ting ability is any maintainable automotive
style group 26R with a minimum of 525 CCA @ 0 deg F.
Before attempting to install the battery make
sure the auto/off/manual switch is in the off
position. Remove the main fuse from the
control panel.
Remove fuse!
9. To complete the external electrical connections snap in the
output circuit breaker cover that is supplied loose with the
generator into the output circuit breaker panel. Allow the cover
to swing down providing weather protection for the circuit
breaker.
The padlock hasp will now protrude through the circuit
breaker cover and it is recommended that once installation
of the generator is completed a padlock be used to provide
suitable security to the generator.
2. Rest the battery on the base of the generator and make the
battery connections. Connect battery positive (red) first then
battery negative (black). Install the plastic battery covers
supplied loose with the generator.

3. Slide the battery under the rubber air in duct until it drops into
the holding well in the generator base. It may be necessary
to gently lift up the bottom edge of the rubber air in duct to
allow the battery to pass underneath until it drops into its final
location.
4. Once the battery is in place double check that the rubber air in
duct has not been displaced and is still fully connected at both
ends.
2. Connect the utility supply from the 50A 2-pole circuit breaker
in the main distribution panel to the terminals in the transfer
switch marked – Utility Source Connection.
NOTE:
Make sure the 50A Circuit Breaker remains OPEN or OFF at this
time.
Utility voltage is potentially leathal. It is
strongly recommened that the electrical portion of this installation be performed by a
qualified electrician.
Local code enforcement may require that AFCI’s be incorporated
into the transfer switch distribution panel. The Transfer Switch
provided with this generator has a distribution panel that will
accept AFCI’s.
Siemens Par t No. Q115AF - 15A or Q120AF - 20A can be
obtained from a local electrical wholesaler and will simply replace
any of the single pole circuit breakers supplied in the Transfer
Switch distribution panel.
