Briggs & Stratton Power Products Home Generator
Owners Manual
NOTE:In some areas you may need to acquire electrical
permits for installing the Home Standby Generator,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.
Fuel Factors
An important consideration affecting the entire installation
is the type of fuel used by your Home Standby Generator.
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/ft3with maximum propylene
content of 5% and butane and heavier gas content of
2.5% and minimum propane content of 90%.
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.
Generator Location
The actual physical location of your HSG has a direct affect
on:
1. The amount of plumbing required to fuel your generator.
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.
Home Standby Generator Location
Before installing generator,consult with homeowner and
convey the following guidelines which may affect the
desired location.
Generator Clearances
The generator enclosure must be at least 5 ft.(152 cm)
from structures having combustible walls and/or other
combustible materials.Leave at least 3 ft. (92 cm) all around
the enclosure including the roof,for adequate cooling,
maintenance and servicing.
Place generator in a well ventilated area which will allow for
removal of deadly exhaust gas.DO NOT install generator
where exhaust gas could accumulate and enter inside or be
drawn into a potentially occupied building.Ensure exhaust gas
is kept away from any windows,doors,ventilation intakes or
other openings that can allow exhaust gas to collect in a
confined area (Figure 1).Prevailing winds and air currents
should be taken into consideration when positioning generator.
General Location Guidelines
• Install the unit outdoors ONLY.
• Place the unit in a prepared location that is flat and has
provisions for water drainage.
• Install the unit where air inlet and outlet openings will
not become obstructed by leaves,grass, snow,etc. If
prevailing winds will cause blowing or drifting,you may
need to construct a windbreak to protect the unit.
• The Home Standby Generator is equipped with an automatic
safety gas “fuel shut-off” valve.
• DO NOToperate the equipment if the “fuel shut-off” valve is
missing or inoperative.
Propane and Natural Gas is extremely
flammable and explosive.
Fire or explosion can cause severe burns or
death.
WARNING
• Operate generator ONLY outdoors.
• Keep exhaust gas from entering a confined area through
windows,doors, ventilation intakes or other openings.
Running generator gives off carbon monoxide,
an odorless,colorless, poison gas.
Breathing carbon monoxide will cause nausea,
fainting or death.
