NATURAL GAS Manual Combustion Calibration Instructions
23. Once the O
2
level is within the specified range at 100%:
•
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
2
value, on the Combustion Calibration Data Sheet
provided with the unit.
24. Lower the Valve Position to the next calibration point using the
(Left) arrow key (if using
Method 1 in step 11) or the Fine Valve Position
–
(Minus) key (if using Method 2).

25. Repeat step 17, 18 and 21 at that valve position and the rest of the valve positions in Table
4-3a through 4-3d, depending on model. The O
2
, NOx and CO should stay within the
ranges shown in these tables.
