This unit is tested in accordance to UL 2200 standards
with an operating temperature of -20 °F (-29 °C) to 122
°F. (50 °C). For areas where temperatures fall below 32
Normal Operating Range °F (0 °C), a cold weather kit is highly recommended.
When operated above 77º F (25º C) there may be a
decrease in engine power. (Please reference the engine
specifications section).
These generators are rated in accordance with UL2200, Safety Standard for Stationary
Engine Generator Assemblies; and CSA-C22.2 No. 100-04 Standard for Motors and
Generators.
** Circuits to be moved must be protected by same size breaker. For example, a 15 amp
circuit in the main panel must be a 15 amp circuit in the transfer switch.

* Engine power is subject to and limited by such factors as fuel Btu content, ambient
temperature and altitude. Engine power decreases about 3.5 percent for each 1,000
feet above sea level; and also will decrease about 1 percent for each 6 C (10 F) above
16 C (60 F) ambient temperature.

The "Ready to Run" on the display 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 voltage is not connected to the
59.0/59.0
unit or if it is below approximately 150-160 volts AC, then
the system will display the message "No Utility Present". This
60 Amp
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 pressure, high
temperature, etc.

With LP gas, use only the vapor withdrawal system. 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 pro-
pane, 10 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.
All pipe sizing, construction and layout must comply 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 10 inches water column for liquid propane.
Prior to installation of the generator, the installer should consult
local fuel suppliers or the fire marshal to check codes and regula-
tions for proper installation. Local codes will mandate correct rout-
ing of gaseous fuel line piping around gardens, shrubs and other
landscaping to prevent any damage.
Special considerations should be given when installing 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.
