4.2.4 Performing a Combustion Efficiency Test

1. After turning ON the analyzer and selecting the appropriate fuel,

press the  or  button to display the Stack Temperature & Effi-

ciency Screen (refer to Section 4.13.10).

2. Position the probe in the flue-gas stream to obtain the hottest

“Stack” reading. Locating the highest stack temperature is very im-

portant for accurate efficiency calculations.

3. Burner-service procedures can now begin. Use the  and  buttons

to scroll through the analyzer’s other display screens (refer to Sec-

tion 4.12). The analyzer readings will update continuously showing

changes in burner performance.

Note: When a calcuation cannot be made because of im-

proper data (i.e., oxygen level above 17.9%), four dashes

“- - - -” appear in place of the calculated value on both the

screen and printout.

Tip: Pressing the HOLD button will freeze all readings and

stop the pump, allowing the operator to scroll through the

Run Mode Screens and examine the readings at any single

point in time. Press ENTER to restart the pump and resume

testing.

4.2.5 Ending a Combustion Test

WARNING! Burn Hazard. Do not touch the probe after

removing it from the stack. Allow the probe to cool before

handling (about 5 minutes).

1. Remove probe from the flue-gas stream.

2. Allow the pump to run until all combustion gases are flushed from

the analyzer as indicated by the O

reading returning to 20.9%.

3. Turn OFF the analyzer per Section 4.10.
