Final Installation Considerations; Fuel System Selection - Briggs & Stratton Home Generator Systems Installation And Startup Manual

More information may be found in Controls in the Operator's
Manual.
System Switch
This two-position switch is the most important control on
the home generator and is used as follows:
• "AUTO" position is the normal operating position. If
a utility power outage is sensed, the system will start
the generator. When utility power is restored, lets the
engine stabilize internal temperatures, shuts off the
generator, and waits for the next utility power outage.
• "OFF" position turns off running generator, prevents
unit from starting and resets any detected faults.
15 Amp Fuse
Protects the home generator DC control circuits. If the fuse
has 'blown' (melted open) or was removed, the engine
cannot crank or start. Replace the fuse using only an
identical ATO 15A fuse. One spare fuse is supplied with the
unit. If fuse was blown or removed, you will need to reset
the excercise timer (see Setting Excercise Timer).

Final Installation Considerations

Engine Oil
NOTICE
Any attempt to crank or start the engine before it has been
properly serviced with the recommended oil will result in
equipment failure.
• Refer to Maintenance and engine manual for oil fill
information.
• Damage to equipment resulting from failure to follow this
instruction will void engine and generator warranty.
This engine is shipped from the factory pre-run and filled
with synthetic oil (API SJ/CF 5W-30W). This allows for
system operation in the widest range of temperature and
climate conditions. Before starting the engine, check oil level
and ensure that engine is serviced as described in the engine
operator's manual.
NOTE: The use of synthetic oil does not alter the required oil
change intervals described in the engine operator's manual.
Battery
The home generator is supplied with a sealed, valve-
regulated, lead-acid rechargeable 12 Volt DC, AGM type,
55 Amp-Hour battery. The battery cables are connected
at the factory. The unit's 15 Amp fuse, which isolates
the battery and prevents the unit from starting, has been
removed for shipping. The battery will lose some charge
prior to installation of the generator. If battery voltage
is below 12 Volts, charge the battery. See Battery in the
Operator's Manual Maintenance section for details.
IMPORTANT: If battery voltage is below 5 Volts, it may not
take a charge and you will need a new battery.
Fuel Supply System
Ensure that all fuel pipe connections are tight, secure and
without leaks.
Ensure that all gas line shutoff valves are OPEN and that
adequate fuel pressure is available whenever automatic
operation is desired.

Fuel System Selection

The engine of your Home Generator System is factory
calibrated to run on natural gas (NG). It may also be
operated on liquefied petroleum (LP) vapor. There is no
additional hardware/equipment required to switch between
either fuel. However, LP fuel inlet pressure must be between
11 and 14 inches water column.
To configure the fuel system for LP use:
1. Open control panel and oil fill access doors.
2. Set generator's system switch to OFF.
3. Remove 15 Amp fuse from control panel.
For a 12kW Home Generator System:
4. Connect the fuel select solenoid by joining the two-pin
electrical connector (A).
A
5. Reinstall 15 Amp fuse in control panel.
6. Set generator's system switch to AUTO.
7. Close control panel and oil fill access doors.
The system is now ready to operate automatically using LP
fuel. With a fixed main jet for LP gas, there is no need to
perform any engine adjustments for LP operation.
