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/ft 3with maximum propylene
content of 5% and butane and heavier gas content of
2.5% and minimum propane content of 90%.
WARNING
• The Home Standby Generator 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.
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 I% 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
on2
I. 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.
Generator Clearances
The generator enclosure must be a minimum of 3 ft.
(92 cm) from combustible material. Leave at least 3 ft.
(92 cm) all around the enclosure for access to the inside of
the enclosure.
The unit's exhaust port must be at least 5 ft. (I 52 cm) from
any building opening (window, door, vent etc.), and the
exhaust must not be able to accumulate in any occupied
area (Figure I).
