Ground Fault Protection
The generator’s receptacles are equipped with Ground
Fault Circuit Interrupter (GFCI) protection. This GFCI
device meets applicable federal, state and local codes.
The GFCI protects against electrical shock that may be
caused if your body becomes a path in which electricity
travels to reach the ground. This could happen if you
touch a “Live” appliance or wire, or are touching plumbing
or other materials that connect to the ground.
When protected by a GFCI device, one may still feel a
shock, but the GFCI should cut current off quickly enough
so that a person in normal health should not suffer any
serious electrical injury.
Connections
to a Building’s Electrical
System
Connections from this generator to a building’s electrical
system must be made through a switching neutral transfer
switch installed by a qualified electrician. The connection
must isolate the generator power from utility power, and
must comply with all applicable laws and electrical codes.
IMPORTANT
: A switching neutral transfer switch MUST
be used when switching between utility and generator power.
Customer’s Responsibilities
•
If considering installation with a transfer swith, read
and follow the instructions given in this manual.
•
Follow a regular schedule in maintaining, caring for
and using your generator, as specified in this manual.
•
ALWAYS disconnect and store indoors the cord used
to connect generator and inlet connection box when
generator is not in use.
To help you make informed choices and communicate
effectively with your installation contractor(s),
Read and understand the Assembly section of
this manual before starting your generator
installation.
You can arrange for proper installation by contacting the
store at which you purchased your generator, your Briggs
& Stratton dealer, a licensed professional electrician or
your utility power provider.
The generator warranty is VOID if permanent fuel
connections to the generator are installed by
anyone other than a licensed gaseous fuel
professional.
The generator warranty is VOID if permanent
electrical connections to the generator are made.
The Gaseous Fuel System
The generator unit has been factory set to run on
liquefied petroleum gas. If the generator is to run on
natural gas, the engine will need to be reconfigured using
the supplied NG Conversion kit. Contact a licensed
professional gaseous fuel technician to install this kit.
The generator engine is fitted with a fuel mixer system
that meets the specifications of the California Air
Resources Board for “tamper-proof” dual fuel systems.
The unit will run on natural gas or liquefied propane
vapor.
•
Use clean, dry fuel, free of moisture or any particulate
material. Using fuels outside the following
recommended values may cause performance
problems:
•
Commercial grade HD5 LPG is recommended -
minimum fuel energy of 2500 BTU’s/ft
3
with maximum
propylene content of 5% and butane and heavier gas
content of 2.5% and minimum propane content of 90%.
•
See “Specifications” for required fuel supply pressure.
Fuel Consumption
See the following table for fuel supply requirements at half
and full load for both natural gas and LP vapor.
•
Contact with the hot and neutral conductor at the same time can
cause electrical shock or burn, even if the circuit is GFCI
protected.
•
Before using the GFCI receptacle, ALWAYS push the test button
to insure it works.
Generator produces hazardous voltage/current.
WARNING
Only qualified electricians and gaseous fuel
technicians should attempt fuel conversion or
permanent connection of this generator. Each
installation must strictly comply with applicable
codes, standards and regulations.
WARNING
•
LP gas is heavier than air and will settle in low areas.
•
Natural gas is lighter than air and will collect in high areas.
•
The slightest spark can ignite these fuels and cause an explosion.
•
IF YOU SMELL GAS - Shut off gas to the generator at the LP
cylinder(s)/source.
•
If odor continues, leave the area and immediately call your gas
supplier or fire department.
Propane and Natural Gas are extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
