13. With the valve position still at 100%, and the combustion analyzer probe in the exhaust
manifold probe opening (see Section 4.2.3):
a. Allow enough time for the combustion analyzer reading to stabilize.
b. Note
the combustion analyzer’s oxygen (O
2
) reading.
c.
If it doesn’t match the value in the O2 Target cell, adjust the
Blower Voltage
using
either the
+
or
–
controls, or press on the field and type the value directly, until the
O
2
value matches the O2 Target.
d. Once it matches the O2 Target, press the
O2
Reading cell and enter the value.
14.
Enter the downstream manometer’s gas pressure reading in the
Downstream Gas
Pressure
field. Note, this field appears only when
Valve Position %
=
100%
.
15. Enter the
Flame Strength
,
NOx
and
CO
readings from the Combustion Analyzer and
multi-meter in the
Reading
cells.
16. Enter the same values, plus the
O
2
value, on the Combustion Calibration Data Sheet
provided with the unit.
17. Compare the NOx and carbon monoxide (CO) values in the
Reading
and
Target
columns.
If NOx readings exceed the target values in Table 4.3-2, below, repeat Step 13c to
increase the O
2
level up to 1% higher. You must then record the increased O
2
value on the
Combustion Calibration sheet (repeat Step 16).
NOTE:
These instructions assume that the
inlet air temperature is between 50°F and 100°F
(10°C
– 37.8°C)
.
18.
Lower the Valve Position to the 80% calibration point using either the
(Left) arrow key or
the Fine Valve Position
–
(Minus) key, then repeat step 13 and 17 at that valve position.
The O
2
, NOx and CO should stay within the ranges shown in these tables. If they are not in
the ranges shown, check the following:
