INSTALLATION
25
6. Connect breather tube (1) to breather port and put clamp (2)
on breather tube.
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.
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.
