7. Connect the gas pressure manometer to the upstream side of the gas train’s SSOV, as
shown in Section 4.2.2 and connect the Combustion Analyzer and Multimeter, as shown in
Section 4.2.3, and ensure that the heating loop is capable of dissipating sufficient heat at
full fire.
8. Verify that the incoming gas pressure to the unit is within the allowable range (see the
Benchmark Pre-Installation Gas Supply Guide (TAG-0047, GF-2030)).
9. Once you have completed the previous step, move the manometer (or use a secondary
one) to the downstream side of the SSOV and press Next to continue.
10. For the NOx requirement choose None.

11. The main Manual Combustion Calibration screen appears. It provides two methods to
ramp the unit’s valve position up or down:
• Method 1: Toggle through the pre-set calibration points till you reach the desired
valve position, then press Go to go to that point (left image below).
• Method 2: Enable Fine VP Step, then manually press the + or – buttons once per
1% to bring the unit to the desired valve position (right image below).
