4.5 Performing a Combustion Test

Ensure that the following has been completed, and then proceed with the combustion test as described below:

• Turn ON analyzer and allow it to warm up (Section 4.2).

• Select fuel being burned (Section 4.3).

• Inset probe into stack (Section 4.4).

• If necessary, insert optional primary air thermocouple into combustion- air stream of burners that use an outside source of combustion air.

1. Press the RUN/HOLD button to start the test. You should hear the pump start running and see the word RUN appear at the top of the Combustion Test screen.

2. Press the ENT button to view the various combustion test screens that contain the data listed in Table 4-1 on Page 4-6.

The screens to the right show typical combus- tion test data for an analyzer equipped with O2, COLOW, NO and NO2 sensors.

TIP: Use the zoom-display to show only the values of O2, CO, and efficiency in large char- acters. Refer to Section 3.13.

Sensor Indicators: The following indicators appear in the sensor's data field depending on certain conditions:
