General Information
1.7 FUEL REQUIREMENTS AND
RECOMMENDATIONS
This unit uses a LP vapor withdrawal system only. This type of
system uses the vapors formed above the liquid fuel in the storage
tank.
Recommended fuels should have a Btu content of at least 2,520
Btus per cubic foot for LP gas. Ask the fuel supplier for the Btu
content of the fuel.
Required fuel pressure for liquid propane, 10 inches to 12 inches
of water column (0.36 to 0.43 psi). The primary regulator for the
propane supply is NOT INCLUDED with the generator.
All pipe sizing, construction and layout must comply NFPA 58
for liquid propane applications. Once the generator is installed,
verify that the fuel pressure NEVER drops below 10 inches
water column.
Prior to installation of the generator, the installer should consult
local fuel suppliers or the fire marshal to check codes and regula-
tions for proper installation. Local codes will mandate correct rout-
ing of gaseous fuel line piping around gardens, shrubs and other
landscaping to prevent any damage.
Special considerations should be given when installing the unit
where local conditions include flooding, tornados, hurricanes,
earthquakes and unstable ground for the flexibility and strength of
piping and their connections.
Use an approved pipe sealant or joint compound on all threaded
fitting.
All installed gaseous fuel piping must be purged and leak tested
prior to initial start-up in accordance with local codes, standards
and regulations.

6 kW
** LP is in gallons per hour/cubic feet per hour.
*** Values given are approximate.
Verify that gas pipe and regulator is capable of providing enough
fuel flow to include household appliances.


Gaseous fuels such as liquid propane (LP)
gas are highly explosive. Even the slightest
spark can ignite fuel and cause an explo-
sion. No leakage of fuel is permitted. LP gas
is heavier than air and tends to settle in low
areas.

A minimum of one approved manual shut-off valve must be
installed in the gaseous fuel supply line. The valve must be eas-
ily accessible. Local codes determine the proper location.

LOCATION

The engine exhaust fumes contain carbon
monoxide, which can be DEADLY. This dan-
gerous gas, if breathed in sufficient con-
centrations, can cause unconsciousness or
even death. This generator must be installed
properly, in strict compliance with applicable
codes and standards. Following installation,
do nothing that might render the system
unsafe or in noncompliance with such codes
and standards.
Operate the generator outdoors ONLY.
• Keep exhaust gases from entering a confined
area through windows, doors, ventilation, crawl
spaces or other openings (Figure 1.3).
• It is highly recommended that carbon monox-
ide detector(s) be installed indoors according
to the manufacturer's instructions/recommen-
dations.
• The generator must me mounted safely per
applicable codes and the manufacturer's speci-
fications. Do NOT alter or add to the exhaust
system, or do anything that might render the
exhaust system unsafe or in noncompliance
with applicable codes and standards.
1.9.1 GENERATOR
Install the generator set, in its protective enclosure, outdoors,
where adequate cooling and ventilating air is always available
(Figure 1.3). Consider these factors:
• The installation of the generator
NFPA 37, NFPA 58, and NFPA 70 standards.
• 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, consider using a wind-
break to protect the unit.
• Install the generator on high ground where water levels will not
rise and endanger it.
• Allow sufficient room on all sides of the generator for mainte-
nance and servicing. This unit must be installed in accordance
with current applicable NFPA 37 and NFPA 70 standards; as
well as any other federal, state and local codes for minimum
distances from other structures. DO NOT install under wooden
decks or structures unless there is at least four (4) feet of clear-
ance above the generator, three (3) feet of clearance on sides
and front, and 18 inches of clearance at back of unit.
• Install the unit where rain gutter down spouts, roof run-off,
landscape irrigation, water sprinklers or sump pump discharge
does not flood the unit or spray the enclosure, including any air
inlet or outlet openings.
NOTE:
must comply strictly with
