Briggs & Stratton Power Products Home Generator System
Owners Manual
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 system.
Generator Location
The actual physical location of your backup generator has a direct affect on:
1.The amount of plumbing required to fuel your generator.
Fuel Factors
An important consideration affecting the entire installation is the type of fuel used by your Home Generator System. The system was factory tested and adjusted using natural gas as a fuel. Liquid propane (LP) may also be used as a fuel (see the Installation Manual).
Although there are specific factors that are inherent to each of these fuels, your location and the duration of possible utility interruptions should guide your selection of fuel type. For urban installations, Natural Gas (if available) should be your fuel of choice. For remote installations, a Liquefied Petroleum (LP) tank might better meet your needs.
For proper engine function, the following fuel guidelines are recommended:
•Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside the following recommended values may cause performance problems.
In engines set up to run on propane (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%.
CAUTION! This equipment is equipped with an automatic safety gas “fuel
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.
2.The amount of wiring required to control and connect your generator.
NOTE: Specific location guidelines are discussed in the Installation Manual. Acquaint yourself with that information and confer with your installer. Be sure to ask how your site might affect installation costs and compliance with local codes and standards.
Generator Clearances
The generator enclosure must be a minimum of 3 ft.
(92 cm) from combustible material (NFPA 37). Leave at least 3 ft. (92 cm) all around the enclosure for access to the inside of the enclosure (NEC Art.
The unit’s exhaust port must be at least 5 ft. (152 cm) from any building opening (window, door, vent etc.), and the exhaust must not be able to accumulate in any occupied area (Figure 1).
