1. fUEL REQUIREMENTS AND RECOMMENDATIONS
The following NG and LPG fuel information is provided to assist
the fuel installer. This information should not be deemed to be
all inclusive or to conflict with local dry fuel codes. Consult your
local fuel supplier or Fire Marshall for guidance on proper local
codes and installations. Local codes will mandate correct routing
of gaseous fuel line piping around gardens, shrubs and other
landscaping to prevent any damage.
Special considerations should be given when installing the
HSB where local conditions include might flooding, tornadoes,
hurricanes, earthquakes and unstable ground. These are
considerations for the flexibility and strength of piping and their
connections.
NG is lighter than air and will collect in high areas. LPG is heavier
than air and will settle in low areas.
Gaseous fuels such as NG and LPG are highly explosive.
Even the slightest spark can ignite such fuels and cause an
explosion, which could cause burns, fire or explosion resulting
in serious injury, property damage or even death. NO leakage
is permitted.
Recommended fuels should have a BTU content of at least 1,000
BTU's per cubic foot for NG, or at least 2,500 BTU per cubic foot
for LPG. Ask the fuel supplier for the BTU content of the fuel.
Before NG fuel lines plans are made, call your NG supplier, provide
them information on the amount cubic feet/hour and the BTU's/
hour that the HSB will use, and ask if the NG meter and primary
regulator can accommodate the addition of the NG generator. NG
companies have different meters for increased BTU demands.
Utilize the "Fuel Consumption (BTU) Chart" contained in this
manual or the Installation Manual for your specific HSB model.
Verify that the current gas meter is capable of providing enough
fuel flow to include household appliances and other loads
including the addition of the HSB. Check the NG primary regulator,
connected at the NG meter output. The correct primary regulator
is set at 5 to 7 inches water column. The existing primary
regulator may be undersized once the HSB is added.
The HSB engine can run on either NG or LPG. The HSB comes
equipped from the factory to run on NG. If your installation
requires the engine to run on LPG, orifices in the master mixer
assembly (carburetor) MUST be changed. The LPG orifices are
shipped with HSB. Refer to "Converting to LPG" in this manual or
the "Installation Manual" for your specific HSB model.

Install the fuel system in accordance with NEC and local codes.
The HSB is EPA Phase 3 certified for LPG and NG fuels.
2. fUEL CONSUMPTION
Air density is less at high altitudes, resulting in less available
engine power. Engine power will decrease 3.5% for each 1,000
feet (300 m) above sea level and 1% for each 10° F (5.5° C) above
77° F (25° C). Make sure these factors are considered when
determining total HSB load.
The gas supply and pipe MUST be sized at 100% load BTU rating.
Understand that as a specific fuel supply line pipe diameter is
extended in length, its ability to carry the volume of gas diminishes
in direct proportion. Improper fuel pipe sizing is the number one
reason for poor operating performance (hard starting, output).
Required fuel pressure for NG is 5 – 7 inches water column.
Required fuel pressure for LPG vapor is 10 – 12 inches water
column. These are estimated fuel supply requirements listed.
Refer to "Fuel Consumption Chart" above.
