•
Enter the Flame Strength, NOx and CO readings from the Combustion Analyzer
and multi-meter in the Manual Combustion Calibration screen's Reading column.
•
Enter the same values, plus the O
provided with the unit.
24. Lower the Valve Position to the next calibration point using the  (Left) arrow key (if using
