INSTALLATION
and related codes. Gas line connections should be made by a
certified plumber familiar with local codes.
Always use AGA approved gas pipe and a quality pipe sealant
or joint compound. The piping should conform to federal and
local codes, rigidly mounted and protected from vibration. Piping
should be black iron or steel to avoid reacting with the sulfur in
the fuel.

NG is highly explosive. Even the
slightest spark can ignite and cause
an explosion, which could cause
burns, fire or explosion resulting in
serious injury, property damage or
even death. NO leakage is permitted.
Safety is important.
Gas pipe sizing is critical to the proper operation of the HSB. The
HSB fuel inlet size has no bearing on the proper gas pipe size
running to the HSB. 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 is diminished in direct proportion.
Pipe sizes are measured by inside diameter (ID) to include any
fittings, valves, elbows, tees or angles. Add 2.5 feet (.76 m) per
bend, tee or angle in the pipe line to the overall distance, for
each 90 degree elbow, add 8 feet (2.4 m) to the measurement.
Use a pipe sealant or joint compound approved for use with LPG/
NG on all threaded fittings to assure zero leakage.
A dedicated NG fuel supply line pipe and primary gas regulator is
mandatory for proper operation. A minimum of one (1) approved,
external manual full flow shutoff gas valve must be installed in
the fuel supply line pipe leading to the HSB. This line must be
easily accessible.
FLEXIBLE FUEL LINE
A flexible fuel line (enclosed with the HSB) is to be installed
between the stationary fuel supply line pipe and the fuel inlet
pipe to the HSB. The purpose of the flexible fuel line is to ensure
that vibration from the HSB does not cause a gas leak at one of
the connection points. The flexible fuel line is not to be installed
underground, in contact with any enclosure parts or contact
with the ground. The entire flexible fuel line must be visible for
periodic inspection and must not be concealed within nor contact
nor run through any wall, floor, partition or fence. Never bend
flexible fuel line to avoid using an elbow. Bending the flexible fuel
line decreases its ability to absorb vibrations and could restrict

the actual fuel flow. Because a HSB engine is prone to vibration,
a flexible piping connection to the gas supply is required.
Connect the HSB to the gas supply piping with an approved
flexible gas line according to local codes. The flexible gas line
also protects against settlement between the HSB pad and the
ridged gas supply piping.
Check for leaks by spraying all connection points with a soap
solution made of dishwashing liquid and water. If you see
bubbles, this indicates a leak and the connection should be
corrected. Check each connection point, there should not be
a visible bubbling when soap solution applied. Installed piping
must be properly purged and leak tested, in accordance with
applicable codes and standards. A sediment trap should be
placed in the fuel supply pipe line to drain any condensation.

the Installation manual for your specific HSB model. Champion
HSB units have been run and tested at the factory prior to
shipment. They do not require any type of break-in period.

Reduced pipe size will affect fuel delivery and performance.
Measure the pipe length from the generator fuel inlet to the
primary gas pressure regulator.
