DANGER
!
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's 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 6 to 8 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 degrees F
above 77 degrees F. 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" contained in this manual or
Installation Manual for your specific HSB model.

3. NG PIPE SIZING
The HSB leaves the factory set up for NG, no changes or
alteration need to be made if NG is the fuel source you are going
to use The following NG 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. All piping must comply with NFPA 54
