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.
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 moistureor any particulate
material. Using fuels outsidethe following recommended
values may cause performance problems.
In engines set up to run on propane (LP) gas,
commercial grade HD5 propanewith a minimum fuel
energy of 2S00 BTUs/fta with maximum propyiene
content of 5% and butane and heaviergas content of
2.5% and minimum propane content of 90%.

AUTION!This
equipment 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, resu_ng 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 backup generator has a
direct affect on:
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 (NFPA 37). Leave at
least 3 fr_(92 cm) all around the enclosure for access to the
inside of the enclosure
(NEC Art, I I 0-26a, Art. I I 0-26b).
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).
Exhaust port must be
S ft (152em)
minimum
distance from building
openings
