General Information

Protection Systems

The generator may have to run for long periods of time
with no operator present to monitor the engine/generator
conditions. Therefore, the generator is equipped with a
number of systems to automatically shut down the unit to
protect it against potentially damaging conditions. Some
of these systems are as follows:
•
Low Oil Level Sensor
•
High Temperature
Sensor
•
Overcrank Detection
•
Overspeed Detection
•
RPM Sensor
•
Underspeed Detection
The control panel contains LEDs which alert the operator
when a fault condition occurs. The above list is not all
inclusive. For more information about alarms and control
panel operation, see Operation.

Emissions

The United States Environmental Protection Agency (US
EPA) (and California Air Resources Board (CARB), for
engines/equipment certified to California standards)
requires that this engine/equipment complies with
exhaust and evaporative emissions standards. Locate
the emissions compliance decal on the engine to deter-
mine applicable standards. For emissions warranty infor-
mation, please reference
warranty. It is important to follow the maintenance specifi-
cations in the manual to ensure that the engine complies
with the applicable emissions standards for the duration
of the product's life.
This generator is certified to operate on Liquid Propane
Vapor fuel or pipeline Natural Gas.
The Emission Control System code is EM (Engine Modifi-
cation). The Emission Control System on this generator
consists of the following:
System Components
- Airbox assembly
Air induction
- Air cleaner
- Carburetor / mixer assembly
Fuel metering - Fuel regulator
- Fuel jet
- Spark plug
Ignition
- Ignition module
- Exhaust manifold
Exhaust - Muffler
- Muffler system

Fuel Requirements

DANGER
Explosion and Fire. Fuel and vapors are extremely
flammable and explosive. Add fuel in a well
ventilated area. Keep fire and spark away. Failure
to do so will result in death or serious injury.
The engine has been fitted with a dual fuel carburetion
system. The unit will run on natural gas or LP gas
(vapor), but it has been factory set to run on natural gas.
The fuel system will be configured for the available fuel
source during installation.
Recommended fuels should have a BTU content of at
least 1000 BTUs per cubic foot (37.26 megajoules per
cubic meter) for natural gas, or at least 2500 BTUs per
cubic foot (93.15 megajoules per cubic meter) for LP gas
(vapor).
NOTE: If converting to LP gas from NG, consult with
your local LP fuel provider to correctly size the generator
fuel tank. See Installation
procedures and details.

Battery Requirements

Group U1, 12V, minimum 300 CCA.
For correct battery maintenance procedures, see
tenance.

Battery Charger

The battery charger is integrated into the control panel
module in all models. It operates as a Smart Charger
which ensures output charging levels are safe and con-
tinuously optimized to promote maximum battery life.

Engine Oil Requirements
