INSTALLATION

OWNER ORIENTATION

This section provides the Home Generator System owner with the information necessary to achieve the most satisfactory and cost effective installation possible.

The illustrations are for typical circumstances and are meant to familiarize you with the installation options available with the Home Generator System. A thorough understanding of these options will provide fundamental control over the cost of installation, as well as ensure final satisfaction and security.

Power Decrease at High Altitude or High Temperature

Air density is less at high altitudes, resulting in less available engine power. Specifically, engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and 1% for each 10° F (5.6°C) above 77°F (25°C). Make sure you and your installer consider these factors when determining total generator load.

INSTALLATION

Federal and local codes, appearance, noise levels, fuel types, and distances are the factors that must be considered when negotiating with an installation professional. As the distance from the existing electrical service and gaseous fuel supply increases, so must the piping and wiring materials.This is necessary to comply with local codes, overcome electrical voltage drops and gaseous fuel pressure drops.

The factors mentioned above will have a direct affect on the overall price of your Home Generator System installation.

NOTE: In some areas you may need to acquire electrical permits for installing the Home Generator System, building permits for installing gas lines, and permits for noise allowances.Your installer should check your local codes AND obtain the permits before installing the generator.

Fuel Factors

An important consideration affecting the entire installation is the type of fuel used by your Home Generator System. The generator was factory tested and adjusted using natural gas as a fuel. Liquid propane vapor (LP) may also be used as fuel by installing the included conversion kit.

For proper generator performance, the following fuel guidelines are recommended:

In engines set up to run on propane vapor (LP) gas, commercial grade HD5 propane with a minimum fuel energy of 2500 BTUs/ft3 with maximum propylene content of 5% and butane and heavier gas content of 2.5% and minimum propane content of 90%.

WARNING

Propane and Natural Gas are extremely flammable and explosive.

Fire or explosion can cause severe burns or death.

•The Home Generator System is equipped with an automatic safety gas “fuel shut-off” valve.

•DO NOT operate the equipment if the “fuel shut-off” valve is missing or inoperative.

PROCEDURES

Unpacking Precautions

The unit is shipped bolted to its mounting pad, ready for installation. Avoid damage from dropping, bumping, collision, etc. Store and unpack carton with the proper side up, as noted on the shipping carton.

Delivery Inspection

After removing the carton, carefully inspect the Home Generator System for any damage that may have occurred during shipment.

IMPORTANT: If loss or damage is noted at time of delivery, have the person(s) making delivery note all damage on the freight bill and affix his signature under the consignor's memo of loss or damage. If loss or damage is noted after delivery, separate the damaged materials and contact the carrier for claim procedures. Missing or damaged parts are not warranted.

Approved Transfer Switches

The Home Generator System should be used ONLY with Briggs & Stratton Power Products UL approved Transfer Switches. Connection to any other transfer switch will void your generator warranty.
