6. FULL FUEL SHUT OFF
A minimum of one accessible, approved manual full fuel shutoff
valve shall be installed in the fuel supply line of the HSB. A
manual full fuel shut off valve should be installed inside the
building, for those locations with inside gas meters. The full
flow shut off valve should be installed in accordance with all
applicable codes and standards.
7. SEDIMENT TRAP
A sediment trap should be installed into the fuel supply line pipe
when using either NG or LPG to drain any condensation. Always
make sure the HSB is completely in the OFF position and the full
flow fuel shut off valve is closed before removing the sediment
trap for drainage. Use a pipe sealant or joint compound approved
for use with LPG/NG on all threaded fittings to reduce the
possibility of leakage. Install a sediment trap downstream of the
HSB shut-off valve as close to the inlet as possible in accordance
with local codes.

INSTALLATION
8. CHECKING PRESSURE WITH A
MANOMETER
This check should only be done when the HSB and ATS have
been installed, properly inspected and ready for testing.
A Manometer is a general term for any device that measures
pressure. A gas Manometer measures gas pressure. It's
important to make sure the correct amount of fuel is being
delivered to the HSB when it starts and at full load usage, the
Manometer provides the ability to check the fuel pressure
throughout the operation of the HSB. A Manometer port should
be placed in the fuel supply pipe line.
CAUTION
!
Remove the plug, install the Manometer. Open the
gas supply valve check to make sure the pressures
are within the specified values for NG or LPG. This is
always a good starting point for evaluations related to
poor performance.
After all appliances have been turn on, start the HSB. If the
Manometer stays within 5 -7 inches of water column for NG,
10 -12 inches of water column for LP, with full load applied to a
proper running HSB, the installation is good.
If the Manometer reading falls below the listed inches of water
column for either specific gas rating while the HSB engine is
starting or running. It may be an indication that the gas meter or
primary regulator is undersized.
If the Manometer reading stays within the specific gas rated
inches water column, but the HSB engine will not start, run
erratic, it may indicate insufficient fuel volume due to long fuel
supply pipe line, incorrect full pipe diameter. Recheck you initial
calculations to ensure where the problem might exist.
Champion HSB units have been run and tested at the factory.
They do not require any type of break-in period.
