Recreational Vehicle Generator
1.2 GENERATOR APPLICABILITY
These generators have been designed and manufac-
tured for supplying electrical power for recreational
vehicles. Do not modify the generator or use it for
any application other than for what it was designed.
If there are any questions pertaining to its applica-
tion, write or call the factory. Do not use the unit until
advised by a competent authority.
DANGER

For fire safety, the generator must have been
properly installed in compliance with ANSI
119.2-1975/NFPA 501C-1974, “Standard for
Recreational Vehicles, Part III – Installation of
Electrical Systems.” The generator also must
have been installed in strict compliance with the
manufacturer’s detailed installation instructions.
After installation, do nothing that might render
the unit in noncompliance with such codes, stan-
dards and instructions.
Use this generator to supply electrical power for
operating 120-volt, single-phase, 60 Hertz, AC elec-
trical loads. These loads can require up to 3,400
watts (3.4 kW) of power, but cannot exceed 28.3 AC
amperes of current at 120 volts.

Do not overload the generator. Some installa-
tions may require that electrical loads be alter-
nated to avoid overloading. Applying exces-
sively high electrical loads may damage the
generator and may shorten its life. Add up the
rated watts of all electrical lighting, appliance,
tool and motor loads the generator will power
at one time. This total should not be greater
than the wattage capacity of the generator. If an
electrical device nameplate gives only volts and
amps, multiply volts times amps to obtain watts
(volts x amps = watts). Some electric motors
require more watts of power (or amps of cur-
rent) for starting than for continuous operation.
1.3 SAFETY
Before attempting to use the generator set, care-
fully read the “Safety Rules” section of this manual.
Comply strictly with these rules to prevent accidents
and damage to equipment and/or property. We sug-
gest copying and posting the “Safety Rules” in poten-
tial hazard areas of the vehicle. Stress safety to all
operators and potential operators of this equipment.
1.4 GENERATOR AC
CONNECTION SYSTEM
This generator set is equipped with dual stator AC
power windings. These two-stator windings sup-
ply electrical power to customer electrical loads by
means of a two-wire connection system. Note, how-
ever, that the neutral is bonded to the frame of the
engine-generator.
The generator may have been installed so that it pow-
ers 120-volt AC loads (Figure 1.1).

1.5 SPECIFICATIONS
1.5.1 FUEL REQUIREMENTS
These generators are equipped with a liquefied petro-
leum (LP) gas fuel system. LP gas is usually aupplied
as a liquid in pressure tanks.
These generators require a “vapor withdrawal” type
fuel system. This type of gaseous fuel system uses the
vapors forming above the liquid fuel in the storage
tank. Air temperature around the storage tank must
be high enough to sustain adequate fuel vaporization.
In colder climates, use of an independent heat source
may be needed to be sure the fuel sufficiently vapor-
izes in the storage tank.
LP gas may consist of propane, butane, or a mixture
of the two gases. Propane vaporizes at tempertures as
low as -20°F (-29°C), but butane returns to its liquid
state when the temperature drops below about 32°F
(0°C). For that reason, a higher ratio of propane is
desired in the gas mixure when temperatures drop
below freezing.
1.5.2 FUEL CONSUMPTION
Fuel consumption is in gal/hr.
