manufacturer does not specifically recommend, ensure that it is
safe for others. Also make sure the procedure, work method or
operating technique utilized does not render the generator unsafe.
Despite the safe design of this generator,
operating this equipment imprudently, neglect-
ing its maintenance or being careless can
cause
possible injury or death. Permit only responsi-
ble and capable persons to install, operate and
maintain this equipment.
Potentially lethal voltages are generated by
these machines. Ensure all steps are taken to
render the machine safe before attempting to
work on the generator.
Parts of the generator are rotating and/or hot
during operation. Exercise care near running
generators.
Installation must always comply with applicable
codes, standards, laws and regulations.
A running generator gives off carbon monoxide,
and odorless, colorless poison gas. Breathing
in carbon monoxide can cause headaches,
fatigue, diziness, nausea, vomitting, confusion,
fainting, siezures or death.

GENERAL HAZARDS
• For safety reasons, the manufacturer recommends that this equipment be
installed, serviced and repaired by a Service Dealer or other competent,
qualified electrician or installation technician who is familiar with applicable
codes, standards and regulations. The operator also must comply with all
such codes, standards and regulations.
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.
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.
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.
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 15A 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.
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 department
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.

UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for damage.
This standby generator set is ready for installation with a factory
supplied and pre-mounted base pad and has a weather protective
enclosure that is intended for outdoor installation only.
This UL listed standby generator set may be packaged with an
automatic transfer switch with built in load center. The combination
transfer switch and load center is pre-wired with a two foot and 30
foot conduit. Circuit breakers for emergency circuit connections are
included (if equipped).
This UL listed, 2-pole switch is rated at 100 or 200 AC amperes at
250 volts maximum. The 100 Amp transfer switch is for indoor use
only. The 200 Amp transfer switch is for indoor/outdoor use (if
equipped).
If this generator is used to power electrical load
circuits normally powered by a utility power
source, it is required by code to install a transfer
switch. The transfer switch must effectively isolate
the electrical system from the utility distribution
system when the generator is operating (NEC 700,
701 & 702). Failure to isolate an electrical system
by such means will result in damage to the gen-
erator and also may result in injury or death to
utility power workers due to backfeed of electrical
energy.
If any loss or damage is noted at time of delivery, have the person(s)
making the delivery note all damage on the freight bill or affix their
signature under the consignor’s memo of loss or damage.
If a loss or damage is noted after delivery, separate the damaged
materials and contact the carrier for claim procedures.
“Concealed damage” is understood to mean damage to the contents of a
package that is not in evidence at the time of delivery, but is discovered
later.
To properly open the roof, press down on the center top lip and release
the latch. If pressure is not applied from the top, the roof may appear
stuck. Always verify that the side lock is unlocked before attempting to lift
the roof.
NEC REQUIREMENTS
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 Part 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.
BEFORE YOU BEGIN
Contact the local inspector or City Hall to be aware of all federal,
state and local codes that could impact the installation. Secure all
required permits before starting the job.
Carefully read and follow all of the procedures and safety
precautions detailed in the installation guide. If any portion of the
installation manual, technical manual or other factory-supplied
documents is not completely understood, contact a dealer for
assistance.
Fully comply with all relevant NEC, NFPA and OSHA standards
as well as all federal, state and local building and electric codes.
As with any generator, this unit must be installed in accordance
with current NFPA 37 and NFPA 70 standards as well as any other
federal, state, and local codes for minimum distances from other
structures.

SITE PREPARATION AND GENERATOR
PLACEMENT
1. Locate the mounting area as close as possible to the transfer
switch and fuel supply.
Leave adequate room around the area for service access
(check local code), and place high enough to keep rising
water from reaching the generator.
Choose an open space that will provide adequate and
unobstructed airflow (see the “Location” section in the
Owner’s Manual).
2. Place the unit so air vents won’t become clogged with leaves,
grass, snow or debris. Make sure exhaust fumes will not enter
the building through eaves, windows, ventilation fans or other
air intakes.
Dig a rectangular area approximately five inches deep and
about six inches longer and wider than the footprint of the
generator. Cover with polyurethane film and fill with pea gravel
or crushed stone. Compact and level the stone. A concrete
pad can be poured if desired.
3. Inspect the generator for shipping damage and if necessary,
file a claim with the shipper.
Remove the bands holding the generator to the wooden pallet.
4. Make sure the lifting equipment to be used has sufficient
capacity to safely handle the weight of the generator.
Use nylon lifting straps and connect them to the lifting eyes
on each corner of the base frame to avoid damaging the
enclosure.
5. Set the generator onto the pad so that the gravel bed extends
several inches beyond the generator on all sides.
Make sure the generator is level within ½ inch.
6. Connect an approved ground strap to the grounding lug on the
base frame and to an approved earth ground or grounding rod
as specified by local regulations.
General Information
5
7. Check the engine oil and, if necessary, add enough of the
recommended oil to bring the level up to the FULL mark on
the dipstick. Be careful not to overfill the crankcase.
CONVERTING TO LP VAPOR
1. The generator was configured for natural gas operation at the
factory. Switching over to LP Vapor is a simple procedure.
On models with a single cylinder engine, begin by
disconnecting and removing the battery if installed.
2. Take the plastic T-handle fuel selector in the poly bag supplied
with the generator and locate the selector tab on the air box
cover. Insert the pin end into the hole in the selector tab
and pull outward to overcome spring pressure. Then twist
clockwise 90 degrees and allow the selector to return in once
aligned with the LP position.
3. On 10 kW units, open the roof, loosen the forward clamp
on the air inlet hose, and slide the hose away from the hose
fitting.
4. Slide the fuel selector pin on the carburetor out towards the
back of the enclosure.
5. Replace the inlet hose and tighten the clamp securely.
6. On all other models, simply remove the air cleaner cover and
slide the fuel selector pin outward from the natural gas to the
LP position.
General Information
6
INSTALLING & CONNECTING GAS LINES
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 shutoff valve
on the fuel line.
3. Where the gas line is to enter the generator, install a T-fitting
to allow for gas pressure monitoring. On one opening of the
fitting install a ¼” NPT nipple and threaded plug. In some
cases a sediment trap may also be installed.
4. 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.
5. 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.
General Information
7
6. After checking for leaks, check the gas pressure at the
REGULATOR to make sure there’s enough gas pressure for
generator operation. See Owner’s Manual for fuel pressure
specifications. If not within these limits, contact your local gas
supplier.
7. When finished checking the gas pressure, close the manual
shutoff valve.
EXTERNAL ELECTRICAL CONNECTIONS
1. Drill a 1 ¾ inch hole and feed the conduit through the hole.
2. Remove the knockout in the back of the connection box, feed
the wires through the back of the box and secure the conduit
with the lock nut.
Seal the hole with silicone caulk. Don’t forget to caulk the hole
inside the house as well.
3. Mount the connection box so that it completely covers the hole in
the wall. Caulk around the sides and top of the box to ensure a good
seal.
Connect all wires to the lugs in the connection box (black to black,
red to red and white to white). Attach the green ground wire to
the ground screw and connect the two small plugs to their mating
receptacle ends.
General Information
8
4. Replace the protective cover plate and retaining screw, and
lock the connection box.
5. For 10-20 kW models, locate the metal hasp that is packaged
in the owner’s manual bag. Insert the hasp in the slot located
on the left side of the external circuit breaker box. Be sure that
the clip of the hasp is facing toward the front of the generator.
If desired, lock the external box.
GENERATOR ACTIVATION

APPENDIX A – EZ SWITCH INSTALLATION &
OPERATIONAL TESTING
1. Before beginning any installation, make sure power is shut
OFF to the main distribution panel and carefully read the
Owner’s Manual that came with the transfer switch.
The distributed load center switch must be mounted close
enough to the main distribution panel to accommodate the
two-foot, pre-wired conduit. Make sure no water or corrosive
substances can drip onto the transfer switch enclosure.
2. Always inspect the switch for shipping damage. Never mount
a transfer switch that shows any evidence of damage.
3. Protect against impact and mount the switch vertically to
a rigid support structure. Make sure the switch is level and
plumb.
The transfer switch is an open transition switch. Open
transition switches prevent electrical feedback between the
generator and the utility by only allowing load circuits to be
connected to one power supply at a time.
4. Each wire in the pre-wired transfer switch is color-coded to
easily match circuits in the main panel to their new breakers
in the transfer switch.
5. When three-conductor wiring is used, two 120 volt circuits
will often share the same neutral wire. To avoid overloading
the neutral, either move BOTH of the circuits that share the
neutral or don’t move either of them.
6. When moving two circuits with a shared neutral, they should
be connected to adjacent positions (one above the other) in
the transfer switch. That will assure that the two hot wires
are on separate phases and will maintain their relationship to
neutral.
Appendix A
12
7. Choose a circuit to be backed up and remove the power lead
from the breaker.
8. Using UL Listed wire nuts, reconnect the power lead to a
matching breaker in the transfer switch.
9. Make sure each circuit moved is protected by the same
size breaker in the transfer switch. 15 Amp circuits must be
connected to 15 Amp breakers and 20 Amp circuits to 20
Amp breakers.
10. Connect the provided large neutral to the neutral bar in the
distribution panel.
11. Install a 2-pole breaker in the distribution panel to protect
the transfer switch. The required amp rating of the breaker
depends on which transfer switch is used. Pre-wired load
center switches the breaker cannot exceed 70 Amps. This
breaker must be compatible with the existing electrical
distribution panel.
Install the breaker in two adjacent empty slots (one above the
other) in the main panel.
12. When all priority circuits have been moved to the transfer
switch, close the main breaker to restore utility power and
make sure utility voltage at the transfer switch is correct.
Refer to NFPA 70-E for the safety equipment required when
working inside a live transfer switch.
Appendix A

circuit breakers in the transfer switch in the OFF position.
3. Locate the transfer handle, insert the metal end into the slot
in the main contactor assembly and pull the handle DOWN to
move the main contacts to the standby power, or generator
position.
NEVER OPERATE THE TRANSFER SWITCH
MANUALLY WHEN LOADS ARE CONNECTED.
4. Put the generator’s mode switch in MANUAL to start the engine.
Allow the engine to warm up, then switch the generator’s
main breaker to the ON position. The generator is now
supplying electricity to the transfer switch but is not carrying
any load.
5. Be sure that voltage and frequency from the generator is
correct. If line-to-line voltage is not approximately 240
volts, refer to the Owner’s Manual for the proper adjustment
procedures. On all models, if line-to-neutral voltage is not 120
volts, check the neutral connection between the generator and
transfer switch.
Appendix A
14
6. When finished checking the voltage, switch the generator’s
main circuit breaker OFF and put the mode switch in the OFF
position to shut down the generator.
7. Make sure the 2-pole circuit breaker installed in the main
distribution panel is in the OFF position.
8. Use the transfer handle to move the main contacts in the
transfer switch to the UP (utility position). Switch the 2-pole
breaker ON in the distribution panel.
9. Now switch the generator’s main breaker ON, and put the
mode switch in AUTO.
10. Shut OFF utility power and make sure the generator starts
automatically.
11. If everything worked properly, switch the main breaker to ON
and make sure that power is automatically transferred back to
the utility.
12. After the engine has completed its cool down cycle and shut
down, shut OFF utility power again.
When the generator is supplying power to the transfer switch,
move the breakers in the switch to the ON position, one at a
time, until the generator has accepted the entire priority load.
13. With the generator carrying the entire priority load, recheck
gas pressure to verify that it is at the same level it was before
the generator was started.
NOTE:
Even if the generator is running smoothly at
this point, a drop in gas pressure indicates that
the supply is barely adequate to supply the
generator’s needs. Changes in the generator load,
or additional gas demand by other appliances
may affect the generator’s performance. Verify
gas pressure and pipe sizing.
Unhook the
manometer and reinstall the port plug.
Appendix A
15
14. Switch the main breaker ON to restore utility power.
The generator will continue to run to allow the engine to cool
down before shutting itself off.
Shut off utility power again. The generator should start and the
entire priority load should transfer to the generator.
Close the main breaker to restore utility power and allow the
engine to cool down and shut itself off.
15. Operational tests are now complete. Refer to – Setting the
Automatic Exercise Function to complete the installation.
APPENDIX B – RTSX AND RTSD TRANSFER
SWITCH INSTALLATION & OPERATIONAL
TESTING
1. Before beginning any installation, make sure power is shut
OFF to the main distribution panel and carefully read the
Owner’s Manual that came with the transfer switch.
To simplify the installation process, the transfer switch
should be mounted as close to the main distribution panel as
possible. Make sure no water or corrosive substances can
drip onto the transfer switch enclosure.
2. Always inspect the switch for shipping damage. Never mount
a transfer switch that shows any evidence of damage.
3. Protect against impact and mount the switch vertically to a rigid
support structure. Make sure the switch is level and plumb.
Check local codes before wiring the transfer switch. Some
jurisdictions require that wiring inside the switch be done by a
licensed electrician.
4. All wiring must be the correct size and type, and must
conform to all codes, standards and regulations. Refer to the
transfer switch Owner’s Manual and the National Electrical
Code for additional information.
Appendix B
16
5. As with any product, design changes can occur over time, so
always refer to the schematics in the transfer switch Owner’s
Manual for the required connections and safety precautions.
6. The transfer switch being used is an open transition switch.
Open transition switches prevent electrical feedback between
the generator and the utility by only allowing load circuits to
be connected to one power supply at a time.
SELECTED CIRCUIT COVERAGE
1. The generator powers only designated circuits that are grouped
together and wired into a separate priority distribution panel.
The transfer switch is installed between the main distribution
panel and the priority panel.
The amperage rating of the transfer switch must be equal to
or greater than the highest amperage rating of the utility and
generator breakers feeding the switch.
WHOLE-HOUSE CIRCUIT COVERAGE
1. The generator will be backing up all electrical loads within the
panel, so the amperage rating of the transfer switch must be
equal to or greater than the amperage rating of the normal
utility service.
Unless a service rated transfer switch is used, a main service
disconnect must be located before the transfer switch. The
transfer switch must be installed between the utility service
entrance and the building distribution panel.
2. A service rated transfer switch is installed between the
service and the main distribution panel. The service rated
switch becomes the main service so no service disconnect is
needed. The existing main distribution panel becomes a sub-
panel.
Appendix B
17
3. The grounding that is normally in the main panel must be
accomplished in the service rated switch and must be
disconnected in the existing distribution panel. Refer to the
National Electrical Code (NEC) for complete information on
grounding and bonding.
ELECTRICAL CONNECTIONS
1. Connect the power leads from both the generator and the
utility to the appropriate lugs in the transfer switch. The lugs
are clearly marked in the switch.
N = Normal Utility Supply
E = Generator Connection Panel
T = Load Distribution Panel
2. Neutral wires from both the utility and the generator are
connected to the same neutral lug in the switch.
3.
Connect the control wires from the generator to the designated
locations. Wires 0, 23 and 194 connect to the terminal strip; N1,
N2, and T1 connect directly to the fuse holders.
4. Complete the transfer switch wiring by connecting the
equipment ground wires from both the utility and the
generator to the ground lug.
5. Being careful to support the lugs, torque the lugs in the
transfer switch to the specifications shown on the transfer
switch. Decal located on the inside of the switch door.
OPERATIONAL TESTING
1. If installing the RTSD switch, the service was changed so make
sure the terminations are good before re-energizing the utility.
Appendix B
18
2 Switch the main utility breaker OFF. Refer to NFPA 70-E for the
safety equipment required when working inside a live transfer
switch.
3. Energize the utility and check line-to-line and line-to-neutral
voltage at terminals N1 and N2 on the transfer contactor. If
line-to-line voltage is not approximately 240 volts, de-energize
utility power and check the terminations between the utility
and N1 and N2.
If line-to-neutral voltage is not approximately 120 volts, de-
energize utility power and check the neutral terminations.
Repeat the same voltage checks on terminals T1 and T2 to
make sure current is flowing properly through the contactor.
4. Switch the generator’s main circuit breaker OFF and put the
mode switch in the OFF position.
5. Make sure utility power is OFF and place all of the individual
circuit
breakers in the main distribution panel in the OFF position.
6. Locate the transfer handle, insert the metal end into the slot in
the main contactor assembly. Pull the handle DOWN to move
the main contacts to the standby power (generator) position.
NEVER OPERATE THE TRANSFER SWITCH MANUALLY WHEN
LOADS ARE CONNECTED.
7. Put the generator’s mode switch in MANUAL to start the engine.
Allow the engine to warm up, then switch the generator’s main
breaker to the ON position. The generator is now supplying
electricity to the transfer switch but is not carrying any load.
8. Check to be sure that voltage and frequency from the
generator is correct. If line-to-
line voltage is not approximately
240 volts, refer to the generator
Owner’s Manual for the
proper adjustment procedures. If line-to-neutral voltage is
not approximately 120 volts, check the neutral connection
between the generator and transfer switch.
