Figure 5-8. Performing a Combustion Test
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.
Sensor Indicators:
The following indicators appear in the
sensor’s data field depending on certain conditions:
(* * *)
Sensor that is not calibrated or installed.
(XXX) Sensor over range
(
- - -
) The calculated data cannot be displayed
because the measured data necessary to
make the calculation is out of range (i.e.,
oxygen level above 18.8%).
2. Use the up and down arrow keys to scroll to the T-STK reading. Loosen
the thumbscrew on the probe stop and move the probe in and out of the
stack until the stack’s core temperature (hot spot) is located as indicated
by the highest T-STK reading; then tighten the thumbscrew to prevent
further probe movement. Locating the highest stack temperature is very
important for accurate efficiency calculations.
3. You can now begin burner service procedures. The analyzer readings
will change quickly to show changes in burner performance.
CAUTION:
Position the water trap with its gas flow arrow
pointing upward. Do not let water condensate go above the
tip of the riser tube. The sensors could be damaged if
water would enter the analyzer. Empty the water trap after
every combustion test. See Emptying the Water Trap on
pages 53 and 87.
4. Pressing the
RUN/HOLD
button holds all readings, stops the pump and
displays the Combustion Test HOLD screen. Press the ▲▼ buttons to
scroll through all test values. Pressing
RUN/HOLD
again restarts the
pump and resumes testing.
