Air-cooled Generators
_ SAVE THESE INSTRUCTIONS - The,manufacturer suggests that these rules for safe operation
be copied and posted near the unit s installation site. Safety should be stressed to all opera-
tots and potential operators of this equipment.
A GENERALHAZARDSA
. For safety reasons, the manufacturer recommends
that the installation, initial start-up and main-
tenance of this equipment is carried out by a
Dealer.
. The engine exhaust fumes contain carbon monox-
ide, 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
Study these SAFETY RULES carefully before install-
ing, operating or servicing this equipment. Become
familiar with this Owner's 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.
The manufacturer cannot anticipate every possible
circumstance that might involve a hazard. The warn-
ings in this manual, and on tags and decals affixed
to the unit are, therefore, not all-inclusive. If using
a procedure, work method or operating technique
the manufacturer does not specifically recommend,
ensure that it is safe for others. Also make sure the
procedure, work method or operating technique uti-
lized does not render the generator unsafe.
/_ Despite the safe design of this generator,
operating this equipment imprudently, neglecting
its maintenance or being careless can cause
possible injury or death. Permit only responsible
and capable persons to operate or 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.
might render the system unsafe or in noncompli-
ance with applicable codes and standards.
. 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.
. Adequate, unobstructed flow of cooling and venti-
lating air is critical to correct generator operation.
Do not alter the installation or permit even partial
blockage of ventilation provisions, as this can seri-
ously affect safe operation of the generator. The
generator MUST be installed outdoors.
* 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 replace-
ment.
. Before performing any maintenance on the gen-
erator, 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 con-
ditions from leaking exhaust gases, fuel leakage,
oil leakage, etc.

iMPORTANT SAFETY iNSTRUCTiONS
Air-cooled Generators
SAFETYRULES
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 opera-
tion. 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 oper-
ating 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 sys-
tem, the generator may crank and start at any
time without warning. When this occurs, load cir-
cuits 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, imme-
diately 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 equip-
ment. Jewelry can conduct electricity resulting in
electric shock, or may get caught in moving com-
ponents causing injury.
FiREHAZARDS/g,
* 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 installa-
tion, do nothing that might alter a safe installation
and render the unit in noncompliance with the
aforementioned codes, standards, laws and regu-
lations.
* Keep a fire extinguisher near the generator at all
times. Extinguishers rated 'TkBC" by the National
Fire Protection Association are appropriate for
use on the standby electric system. Keep the extin-
guisher 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 com-
bustible materials are left in the generator com-
partment, or on or near the generator, as FIRE or
EXPLOSION may result. Keep the area surround-
ing the generator clean and free from debris.
Gaseous fluids such as natural gas and liquid pro-
pane (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 permit-
ted.

Air-cooled Generators
1.1 UNPACKING/INSPECTION
After unpacking, carefully inspect the contents for
damage.
. This standby generator set is ready for installa-
tion 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 pack-
aged 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).
-,_ WARNING _-
/_ 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 con-
signor'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 cen-
ter 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.
Section 1 - Genera[ information
1.2 PROTECTION SYSTEMS
Unlike an automobile engine, the generator may have
to run for long periods of time with no operator pres-
ent to monitor engine conditions. For that reason,
the engine is equipped with the following systems
that protect it against potentially damaging condi-
tions:
1. Low Oil Pressure Sensor
2. High Temperature Sensor
3. Overcrank
4. Overspeed
5. RPM Sensor
6. Low Battery
There are readouts on the control panel to notify
personnel that one of these failures has occurred.
There is also a System Set LED (single cylinder) or a
Status message on the display (V-twins) that displays
when all of the conditions described in the "System
Set LED" section are true.
1.3 NEC REQUIREMENTFORARC
FAULTCIRCUITiNTERRUPTION
BREAKER FOR BEDROOMS
In 2001, the National Electric Code (NEC) intro-
duced a requirement for new construction. This new
requirement indicates the need for Arc Fault Circuit
Interrupters to be used to protect the complete
branch circuit that feeds a dwelling bedroom. The
actual NEC requirement is indicated below.
@ 1.3.1 SECTION 110.11 ARC FAUET CIRCUIT
INTERRUPTER PROTECTION
1. Definition: An arc fault circuit interrupter is a
device intended to provide protection from the
effects of arc faults by recognizing characteristics
unique to arcing and by functioning to de-ener-
gize the circuit when an arc fault is detected.
2. Dwelling Unit Bedrooms: All branch circuits that
supply 125 volt, single-phase, 15 and 20 ampere
outlets installed in dwelling unit bedrooms shall
be protected by an arc fault circuit interrupter
listed to provide protection of the entire branch
circuit.
Section 210.12 requires that AFCI protection be
provided on branch circuits that supply outlets
(receptacle, lighting, etc.) in dwelling bedrooms. The
requirement is limited to 15 and 20 ampere, 125
volt circuits. There is no prohibition against provid-
ing AFCI protection on other circuits or in locations
other than bedrooms. Because circuits are often
shared between a bedroom and other areas such as
closets and hallways, providing AFCI protection on
the complete circuit would comply with 210.12.

Section 1 - General information
Air-cooled Generators
GENERAL
NFORMATON
If during the installation of the home standby system
the decision is made to provide back up power to a
bedroom branch circuit, then the circuit breaker in
the transfer switch should be replaced with an Arc
Fault Circuit Interrupter.
It is most important that breakers only be switched
like for like. For instance, if replacing a 15A breaker,
it MUST be replaced with a 15A AFCI breaker.
Likewise, a 20A breaker MUST be replaced with a
20A AFCI.
These AFCI breakers are available at the nearest
hardware store.

1.7 SYSTEMSETLED
The "System Set" LED (single cylinder) or "Ready to
Run" on the display (v-twin) is ready when all of the
following conditions are true:
1. The AUTO/OFF/MANUAL switch is set to the
AUTO position.
2. The utility voltage being supplied to the unit is
being sensed by the PCB. If the utility sense volt-
age is not connected to the unit or if it is below
approximately 150-160 volts AC, then the system
set light will flash rapidly (8kW). This indicates
that if the AUTO/OFF/MANUAL switch is placed
in the Auto position, the generator will start.
3. No alarms are present, for example, low oil pres-
sure, high temperature, etc.
1.8 FUEL REQUIREMENTS
AND RECOMMENDATIONS
With LP gas, use only the vapor withdrawal sys-
tem. This type of system uses the vapors formed
above the liquid fuel in the storage tank.
The engine has been fitted with a fuel carburetion
system that meets the specifications of the 1997
California Air Resources Board for tamper-proof dual
fuel systems. The unit will run on natural gas or LP
gas, but it has been factory set to run on natural gas.
Should the primary fuel need to be changed to LP
gas, the fuel system needs to be reconfigured. See the
reconfiguring the Fuel System section for instructions
on reconfiguration of the fuel system.
Recommended fuels should have a Btu content of at
least 1,000 Btus per cubic foot for natural gas; or at
least 2,520 Btus per cubic foot for LP gas. Ask the
fuel supplier for the Btu content of the fuel.
Required fuel pressure for natural gas is five (5)
inches to seven (7) inches water column (0.18 to
0.25 psi); and for liquid propane, I0 inches to 12
inches of water column (0.36 to 0.43 psi). The
primary regulator for the propane supply is NOT
INCLUDED with the generator.
NOTE:
All pipe sizing, construction and layout must com-
ply with NFPA 54 for natural gas applications and
NFPA 58 for liquid propane applications. Once the
generator is installed, verify that the fuel pressure
NEVER drops below four (4) inches water column
for natural gas or I0 inches water column for liq-
uid propane.
Prior to installation of the generator, the installer
should consult local fuel suppliers or the fire mar-
shal to check codes and regulations for proper instal-
lation. Local codes will mandate correct routing of
gaseous fuel line piping around gardens, shrubs and
other landscaping to prevent any damage.

Special considerations should be given when install-
ing the unit where local conditions include flooding,
tornados, hurricanes, earthquakes and unstable
ground for the flexibility and strength of piping and
their connections.
Use an approved pipe sealant or joint compound on
all threaded fitting.
All installed gaseous fuel piping must be purged and
leak tested prior to initial start-up in accordance with
local codes, standards and regulations.

Gaseous fuels such as natural gas and liquid
propane (LP) gas are highly explosive. Even the
slightest spark can ignite such fuels and cause
an explosion. No leakage of fuel is permitted.
Natural gas, which is lighter than air, tends to
collect in high areas. LP gas is heavier than air
and tends to settle in low areas.

To reconfigure the fuel system from NG to LR follow
these steps (Figure 1.4):
NOTE:
The primary regulator for the propane supply is
NOT INCLUDED with the generator, A fuel pres-
sure of I0 to 12 inches of water column (0,36 to
0.43 psi) to the fuel inlet of the generator MUST
BE SUPPLIED,
1. Turn off the main gas supply (if connected).
2. Open the roof and remove the door.
3. Remove the battery (if installed).
4. Take the plastic T-handle fuel selector in the poly
bag supplied with the generator.
5. Locate the selector knob on the air box cover,
behind the yellow air filter door and power
bulge. The unit comes from the factory in the NG
(Natural Gas) position. Grasping the T-handle,
insert the pin end into the hole in the selector
knob and pull out to overcome spring pressure
and then twist clockwise 90 degrees and allow
the selector to return in once aligned with the LP
(Liquid Propane) position.
6. Save this tool with the Owner's Manual.
7. Install the battery, door and close the roof.
8. Reverse the procedure to convert back to natural
gas.
