Part No. 101049
5. Install fuel inlet chamber to mixer body. Tighten fuel inlet
chamber screws (3). Screw Tightening Torque: 26.0 lb.-in
(2.94Nm).
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.
