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.

WARNING

Generator produces hazardous voltage/current.

•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.

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.

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.

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.

WARNING

Propane and Natural Gas are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•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.

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/ft3 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.
