Part No. 101049 Rev. B
FLEXIBLE FUEL LINE
A
fl
exible 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
fl
exible line is to ensure that
vibration from the HSB does not cause a gas leak at one of the
connection points.
The
fl
exible fuel line is not to be installed underground, in contact
with any enclosure parts or contact with the ground. The entire
fuel line must be visible for periodic inspection and must not
be concealed within not contact nor run through any wall,
fl
oor,
partition or fence.
Never bend a
fl
exible fuel line to avoid using an elbow. Bending
the
fl
exible fuel line decreases its ability to absorb vibrations and
could constrict the actual fuel
fl
ow. Because the HSB engine is
prone to vibration, a
fl
exible piping connection to the gas supply
is required. Connect the HSB to the gas supply piping with an
approved
fl
exible gas line according to local codes. The
fl
exible
gas line also protects against settlement between the HSB pad
and the ridged gas supply piping.
!
CAUTION
Check for leaks by spraying all connection points with
a soap solution made of dishwashing soap and water. If
you see soap bubbles, this would be an indication of a
leak and it should be corrected. Check each connection
point, there should not be a visible bubbling with the
soap solution applied. Refer to the “Fuel Pipe Sizing
Chart” contained in this manual or the Installation
Manual for your speci
fi
c HSB model. Installed
piping must be properly purged and leak tested, in
accordance with applicable codes and standards.
Champion HSB units have been run and tested at the factory
prior to shipment. They do not require any type of break-in
period.
WIRE SIZING
All installations must comply with National, State and Local
codes. It is the responsibility of the installer to perform an
installation that will pass the
fi
nal electrical inspection. Conductor
wire sizes must be adequate to handle the maximum current to
which they will be subjected. The installation must comply fully
with all applicable codes, standards and regulations.
All power cables must enter the enclosure through the knockouts
provided. If not using knockouts, conduit entry into the enclosure
must be at or below knockouts to maintain the Type 3R rating.
NEMA 3R enclosures are rated and tested for outside installation,
they are water proof enclosures and only come with knockouts
on the bottom side of the enclosure. If a NEMA 3R enclosure
in used for an inside installation, a greenlee type punch will
be required to make a knockout(s) on the side or top of the
enclosure. Conduits should be arranged to provide separation
between the Utility Source and HSB Source supply conduits
inside the enclosure.
Conductor wires must be properly supported, of approved
insulated qualities, protected by approved conduit and of the
correct wire gauge size in accordance with all applicable codes.
Before connecting wiring cable to terminals, remove any surface
oxides from the cable ends with a wire brush. These oxides can
work as insulators, preventing proper
fl
ow of current and signals.
!
CAUTION
Use a torque wrench to tighten conductors, being sure
not to overtighten, or damage to the switch base could
occur. If not tightened properly, a loose connection
would result, causing excess heat which could damage
the switch base.
